Question Corner

The following is a collection of questions from fan mail that Daisuke Ashihara has answered in manga volumes and on the official World Trigger Twitter.

Volume 5 - Question Corner 1
Q: Do Border agents get paid? A: I might show it one day, but yes, agents do get paid. B-Rank agents get a fee per Trion Soldier they defeat. A-Rank agents have a salary + fee per Trion soldier. C-Rank trainees do not get paid.

Q: Are there any requirements, like fitness tests, for applying to Border? A: There are basic fitness tests, basic achievement tests, and an interview. Other than having low Trion levels or a criminal record, you won't get rejected (Osamu was nearly rejected).

Q: Can the Trion Gland be strengthened with training? Does Trion get replenished with time or sleep? A: Just like lung capacity and muscle strength, it can be improved somewhat, and does recover with nutrition and rest.

Q: Why are all Border agents young? A: The biggest reason is that the younger you are, the more your Trion gland can grow. Agents over age 20 whose growth has stopped often go into administration (like Sawamura).

Q: Do Border high schoolers go to the same school? A: For better coordination of agent schedules, they often go to the same school, but they don't have to.

Q: Do Trion bodies feel pain from Trigger attacks? A: There is a pain sensation that tells you what part of your body got damaged. This can be turned completely off.

Q: Can you use Trion to heal damage? A: It is impossible to repair a Trion body. The Trion Body is basically disposable. Once destroyed, you need to create another one, which takes time and more Trion.

Volume 5 - Question Corner 2
Q: How do you become an Operator? A: Some apply for it from the beginning, and some change track from combatants.

Q: Can only girls become Operators? A: Almost all Operators are female. They say this is because women have higher parallel processing capabilities. Men can be Operators too. On the other hand, almost all the Engineers are male.

Q: Is there a limit to the number of members on a Squad? A: A team of five, with four Combatants and one Operator is the limit. Any more and it goes over the Operator's data processing capability.

Q: Why do Osamu and Chika have different outfits? Do they have free rein? A: Chika's outfit is the standard C-Rank female Sniper (up to junior high) uniform. Jin made the adjustments to Osamu's. That's why it has Tamakoma's shoulder.

Q: Why is Narasaka the bamboo guy in the mushroom family? A: To avoid unnecessary bloodshed.

Q: Is Raijinmaru male or female? A: Raijinmaru looks female, but everyone at Tamakoma probably thinks Raijinmaru is male.

Q: Was Yūma eating a lunch made by Osamu in chapter 2? A: He brought it himself.

Q: What's Osamu's eyesight? A: Both eyes are 20/100.

Q: Does Osamu take his glasses off when he takes a bath? A: Probably not. He may even wear them while he's asleep. Perpetual Glasses.

Volume 6 - Question Corner 3
Q: Does Arashiyama have parents? A: Yes. His dad is an office worker and his mom works part-time. He also lives with his grandmother, a brother and sister, and one dog.

Q: What kind of jobs does Karasuma have? A: Delivering the newspaper, grocery cashier, waiter. There are rumors that more female customers come in on his shift days.

Q: How do you feel about Osamu sweating all the time? A: Osamu breaking into a cold sweat is like ketchup on an (his glasses are the eggs).

Q: Is there an age limit to applying to Border? A: There isn't a strict age limit as long as you have Trion, but you're more likely to be hired the younger you are because the Trion Gland can grow more.

Q: Can you Teleport in rapid succession? A: Distance = Trion consumed. Longer distances (over 30m) require a longer resting interval of several seconds. Short distances (2-3m) require 0.5 seconds or so.

Q: Is World Trigger abbreviated to "WorTri" or just "Trigger"? A: My editor calls it "Trigger". My manager calls it "WorTri". My assistants and I never abbreviate it and call it "World Trigger".

Q: How far into the future can Jin see? A: He can see several years into the future that's pretty certain (high probability of actualization). But he can't see very far into uncertain futures that might be tinkered with.

Q: Who has more Trion, Chika or Izumi? A: Chika. Izumi is a prodigy, but Chika is a monster.

Q: Was Raijinmaru purchased at a pet shop? A: Director Rindō brought her from somewhere. It's a mystery.

Q: Why is Kazama so short? A: "Big power in a small package". That's Kazama.

Volume 7 - Question Corner 4
Q: How are Trion body uniform designs decided? A: There are several basic designs, and each squad adds their own embellishments. The jersey style is popular because it doesn't intimidate civilians. Some suits, like Kazama Squad's, have functional additions.

Q: Is Trion capacity inherited? A: Sometimes, but not necessarily. For example, Chika's parents don't have high Trion.

Q: Do Operators go on Away Missions? A: According to Usami in Volume 3, they do. Border has portable computers that operate on Trion, enabling them to support agents without a power supply.

Q: How many A and B-Rank squads are there? A: There are currently eight A-Rank Squads and 20 B-Rank Squads, but it changes from time to time as the ranks change.

Q: What does Reiji like to cook? A: A dish of stir-fried vegetables with meat, meat and more meat. It's become a staple at Tamakoma.

Q: How do newly-enlisted agents find mentors? A: First you watch matches or videos of people who are good and study up. When you get to a certain level of competence, talk to them directly or get someone to introduce you. Or you can challenge them in individual matches.

Q: Has anyone risen to A-Rank without mentors (besides the initial members)? A: Several. Like Izumi, Kikuchihara and Yōsuke. You can get better without a mentor if you have good rivals.

Q: When Tachikawa destroyed the Ilgar, did he teleport or jump from the roof? A: He probably used an Optional Trigger called Grasshopper. Midorikawa uses it in this volume.

Q: Do A-Rank high schoolers all go to the same school? A: There are two schools affiliated with Border (one regular and one ). Kodera, Narasaka, Usami, Utagawa and Kikuchihara go to the college prep school. Most of the others go to a regular school. Some, like Konami (and Kitora), go to a private girls school.

Q: Where is the physical body while the Trion body is activated? A: Stored where the Trion body was, inside the Trigger Holder.

Volume 7 - Question Corner 5
Q: Tell us more about the gun Trigger (a shotgun?) Suwa was using in chapter 45. A: It's a shotgun that blasts a bunch of largish bullets. You can adjust the angle of the blast to some extent. Pro: high firepower. Con: slow reload.

Q: How drastically can Scorpion change shape? Can you wrap it around your whole body? A: The shape can change a good bit. How much it can expand depends on your Trion levels, but the wider it is spread, the weaker it becomes. It would be as fragile as glass if you put it around your body. Chika might be able to pull it off.

Q: Tell us more wacky anecdotes about Tachikawa, who's bad at everything non-combat. A:
 * He pronounced the English "danger' like "dang-ah".
 * He thought an unplugged computer was broken.
 * He picked out the dried fruit from granola and threw the rest away.

Q: Why are Osamu’s glasses frames under-rim style? A: He picked it up from his father (who's still alive, by the way).

Q: When do people start to call their seniors "Mr./Mrs./Miss"? A: People older than high school and college start to get called "Mr./Mrs./Miss". So when Osamu doesn't add "Mr." to Kazama...

Q: The round parts of Kazama Squad's uniform react when they activate Chameleon. What're they doing? A: The uniform is embedded with a mechanism that reduces the Chameleon's Trion consumption. But it increases the cost of the Trion Body.

Q: Is Utagawa an Attacker or All-Rounder? A: The first editions of the graphic novels (in Japan) have it wrong. He's an All-Rounder.

Q: Can you not put away Kogetsu only while it's selected, or the whole time the Trigger is on? A: Once the Kogetsu is selected, it is always out. It disappears in the art sometimes, but that's just me forgetting to draw it.

Volume 8 - Question Corner 6
Q: How heavy is one of Miwa's Lead Bullets? A: About 100kg (220lb). Yūma's Anchor is about twice that.

Q: What is the relationship between Tsukimi and Tachikawa? (Tachikawa's birthday comes earlier so he's older, isn't he)? A: Tsukimi is Tachikawa's childhood friend and mentor when it comes to strategy. It goes Azuma, Tsukimi (and many other pupils) and then Tachikawa.

Q: The Trion body wears a Border uniform when the Trigger is activated, but are the Trion bodies automatically made wearing a uniform? A: The clothing upon Trigger activation can be an outfit specifically chosen by the Agent or can just be the default outfit. You can register multiple outfits of your own choosing.

Q: When Yūma's wounds healed after he was struck by a car, does that mean that his Trion Body repaired itself? A: Yes. Yūma's regular body is less durable than his Trion Body, but it has a repair function. A regular Trion Body wouldn't be damaged in a car crash.

Q: Do Sniper rifles only stay out in gun form, or can they be put away at will? Can one be carried around as a smaller version? A: Once guns are out, they stay out. If you "put it away", another gun's worth of Trion must be used to take it out again.

Q: Can All-Rounders snipe too? A: Not really. An All-Rounder is good at close and mid-range combat. The only Perfect All-Rounder who can also snipe is Reiji.

Q: is it important for Snipers to have good eyesight? A: Eyesight is perfected for the Trion Body, so it doesn't matter. People with glasses keep them because the glasses are tied to their identity.

Q: Is Satori's double-barreled sniping technique highly advanced? Did he need to practice it, or was it his natural talent? A: He practiced. Satori pursued firepower and awesomeness to perfect it. But nobody's going to imitate him.

Volume 8 - Question Corner 7
Q: Does Konami's Trion Body have short hair to conserve Trion? A: It's most likely so her hair doesn't get in the way during a battle. It's her old hairstyle.

Q: Tokieda lists cats as one of his likes, but does he have any at home? A: He has two. Arthur, a brown tabby, and a black and white cat named Tomio.

Q: Why does Yōtarō wear a helmet? A: Because he's always in battle mode. Reiji made it for him.

Q: Who is the main character, Yūma or Osamu? A: Either one. I personally consider the four people I drew on the first title page as the main characters (Yūichi Jin, Chika Amatori, Yūma Kuga, and Osamu Mikumo)

Q: If you were to eat Bonchi in Jin's room without asking him, would he get mad at you? A: You would start to get shipments of Bonchi fried rice crackers sent to your room.

Q: Do gates open only in Mikado City or do they also open elsewhere? A: They open around the world and people secretly get kidnapped. But since a big one opened in Mikado, the world thinks that they only open in Mikado.

Q: Why is Tachikawa affiliated with Kido when Shinoda taught him how to use a sword? A: The Kido Faction prioritizes away missions, and the Shinoda Faction prioritizes defense. Tachikawa is interested in Away Missions. It's not because he disagrees with Shinoda.

Q: Does the Away Team try to avoid detection? A: They sneak in to get Trigger Technology through trades or negotiations. If a country is in the middle of a war, they will fight off attackers and take their Triggers.

Q: Konami and Arashiyama are related. Did they join around the same time? A: Konami joined much earlier. Konami has been around since old Border, and Arashiyama joined after the current base was built.

Q: Does Kikuchihara actually like anything? A: Friends and colleagues.

Volume 9 - Question Corner 8
Q: Rinji was Osamu’s mentor, right? So shouldn't Osamu show more respect towards Rinji's sister Chika? A: Osamu doesn't act that way towards Chika because he's insensitive. Both Rinji and Chika herself allow him to be informal with her.

Q: Does Kōda Squad (New Three Idiots) have any other formations besides Bird? A: They currently have ten formations including Dragon, Snake and Horse. Nine of them are "everyone attack at once" and one is "everyone run for your lives".

Q: After an agent returns to their normal body, do they have to rebuild the Trion body like they do after they Bail Out? A: When an Agent returns to their normal body on their own, their Trion body is "put away". They can decide to use the same Trion body next time, but the damage to the body won't be repaired.

Q: Are the wires used in Reiji's traps are the same as the ones Kitora uses? Is the box used inside the trap a Meteor? A: It's a Trigger called Spider and it's the same as Kitora's. It can do various things depending on which Trigger it's combined with. The box used in the trap was a Meteor (in 27 pieces).

Q: Izumi synthesized a Tomahawk by combining a Viper and a Meteor. Can he do that because he's a genius or could Osamu do it too with practice? A: It's possible to do it with practice, but it would take some time. If Osamu tried to shoot a Tomahawk now, it would take him a whole minute to prepare. It only takes Izumi two seconds.

Q: How far can an agent deploy a remote Shield like the ones used in the battle with Ranbanein? A: It depends on individual ability, but they should be able to deploy a Shield up to 25 meters away. This remote defense is one of the reasons that Shield is superior to Raygust's Shield Mode.

Q: Do only A-Rank squads have their own emblems? A: Once a squad makes A-Rank they can make their own emblem. Even if they are eventually demoted to B-Rank, they can continue to use their emblem until the squad disbands.

Q: Can you transform without saying "Trigger on" out loud? A: If you are touching the Trigger holder and give a clear signal, you can be silent or use a different word. You can even have your own unique transformation phrase.

Volume 10 - Question Corner 9
Q: Please tell us if there are any characters who are living in Tamakoma Branch. A: Branch Manager Rindō, Yōtarō, Jin, and Reiji live there, but rooms are provided for everyone and people like Konami or Usami frequently stay over. There are plans to provide rooms for Osamu, Yūma, and Chika too.

Q: During the battle versus Ranbanein, Okudera used Full Guard; does that mean you can use other Triggers if you just put the Kogetsu in a sheath without deactivating it? A: Even without putting it in a sheath you can turn the Kogetsu off, but the sharpness will become zero. You won’t be able to use it and you can’t deactivate it either, so it’s a big hindrance. Deactivating the Kogetsu and then remaking one later when you need it again will mean it’s not a hindrance, but it will use up trion. It is the same as gun-type Triggers.

Q: Does the trion gland decay with age? A: It seems it slowly decays if it is not used. Using it maintains it to a certain extent.

Q: What is Osamu’s favourite out of his mother’s home-made dishes? A: Cream croquettes. Even the white sauce is hand-made.

Q: Are all the agents from Mikado City? A: Generally they are, but scouting occurs in other prefectures too so there are a small number from other regions.

Q: What is it called when Shooters produce trion in cube form? A: Trion cube, nata de coco (fermented coconut cubes), sugar cube, Suwa, tofu, etc. Everyone calls it whatever they want.

Q: While Chameleon is in use, can Hound bullets track you? And do you show up on Radar? A: Hound bullets that use "Detection Guidance" can, but usually they are intercepted by walls and so on. Even during Stealth Mode, you still show up on Radar, so it’s possible to use that to make a rough counter-attack.

Q: Yūma’s C-rank uniform is black; was this also specially arranged by Jin? A: It seems to be something that Yūma’s father, Yūgo, had configured a long time ago. It is a remnant from the times of Old Border.

Q: Why is Suwa smoking even though he’s in a Trion Body? A: It’s to show off. Since there have been no depictions of ashtrays, there is also the possibility that it might not actually be a cigarette.

Volume 10 - Q&A from Jump Festa 2015
Q: Can Replica eat food?? A: He cannot gain nutrition from food, but as a poison taster he can eat it. Good for survival.

Q: What’s the reason behind Jin's sunglasses not slipping? A: It’s connected at the back.

Q: Can Replica sleep? A: He doesn’t need to sleep to recharge, but he does have a ‘sleep mode’-like feature. To stay out of the way when he isn’t needed, he is on standby (sleep mode) in the ring.

Q: Out of the current characters, who is about as strong as Yūgo? A: Yūgo was as strong as the current Shinoda-san. Four years ago, Yūgo would have been stronger, but Shinoda-san trained every day and caught up.

Volume 13 - Question Corner 10
Q: Do normal trion body users also not need to sleep but need to eat? A: Trion body users need rest just like usual. This is because the brain and nerves get fatigued, and because the trion gland does not recuperate while using a trion body.

Q: Is Raygust’s shield mode a separate trigger? A: Shield mode is not an option, but one of Raygust’s standard functions. As such it does not use a Trigger slot.

Q: Are there any differences in the amount of time it takes a person to recreate a trion body? A: The more trion a person has (= the more trion that gets used in battle) the bigger the cost of constructing a Trion Body, so recreating it will take more time. Chika takes a lot of time but Osamu can return to battle fairly quickly (in about 1~2 hours time).

Q: What do Border Agents do on their days off when they’re not on duty and there’s no school? A: Polishing their skills in solo Rank Wars, studying the recordings, immersing in hobbies, feeling sad, falling asleep, thinking about what to buy with their wages, being swamped with homework, playing around, dancing with joy, visiting grave sites, or thinking about the person they like.

Q: In the end, did Satori have to face any penalties after Chika blew a hole in the wall of HQ with that Ibis? A: It seems that, due to Azuma-san and Arashiyama covering for him, he got away with just a chop from Kinuta-san.

Q: What is the difference between ‘turning off Kogetsu and then recreating it’ and ‘putting away Scorpion and taking it out again’? A: ‘Putting away Scorpion’ is similar to ‘putting Kogetsu back in its scabbard’. They’re both out of the way, but Scorpion is less of a burden. ‘Turning off Kogetsu’ means to destroy both the scabbard with the blade.

Q: What distance is the limit for a sniper Trigger to hit its mark? A: If it’s an unmoving target, someone who is good at premise sniping like Narasaka or Hanzaki can hit the mark from 1km away with an Egret. An Ibis or Lightning’s range will be shorter.

Q: Even though Yūma doesn't need to sleep since gaining a Trion body (Chapter 94), does he get hungry? A: I believe that Yūma needs to eat food to send nutrients to his dying body, so he eats more than others.

Volume 18 - Question Corner 11
Q: C-rank members are only supposed to have one weapon Trigger, but why did Chika train with a bagworm on at Tamakoma? A: That was a Tamakoma Trigger that Reiji-san provided to drive the foundations of sniping into her. It is set with the three types of sniper rifles and bagworm.

Q: Are there any branches besides Tamakoma and Suzunari? A: Border has 6 branches: Tamakoma, Suzunari, Wataayu, Yumite District, Hayanuma, and Kuma. Its personnel are mostly those who prioritise work or school and don’t aim for A-Rank (they do not participate in the twice a week Rank Wars). The branches are placed on the outer edge of the Danger Zone. Other than Tamakoma, the branches function as a point of contact for local residents.

Q: How is an All-Rounder defined? A: An All-Rounder is ‘an agent who has earned more than 6,000 solo points in both Attacker and Gunner Triggers respectively’. Right now Border’s overall level is on the rise and there are those who say it should be raised to above 8,000.

Q: How do you think of names for the characters? A: Surnames are just ones that fit, roll off the tongue easily, and isn’t too unique. First names are chosen by thinking about the parents that would be picking the names for these people.

Q: Can’t you train your Trion Gland in Virtual Combat Mode? A: You can’t. You can only train your reflexes and increase combat experience in virtual mode. Trion Gland can only be trained through using trion.

Q: What is the difference between Shield, Raygust Shield Mode, and Escudo? A: Shield: Can change shape. Durability changes according to the size of the surface area. Moving it lowers the durability. Raygust: Can change shape. Durability changes a little according to the size of the surface area. Even if you wave it around in your hand the durability will not change. Escudo: Cannot change shape. Cannot be moved. High durability. Needs a place (such as a wall or floor) to grow out of.

Q: Can Escudo defend from Lead Bullets? A: Escudo converts trion into a material form, so it can. It is treated the same as blocking Lead Bullets with walls or buildings.

Volume 19 - Question Corner 12
Q: In Volume 2, before he used Lead Bullet, Miwa loaded a Trigger into the handgun, do Triggers in the shape of other guns have that kind of feature too? A: Miwa’s Lead Bullet is customized. By loading an external magazine that was created beforehand, Lead Bullet can be used as the "handgun’s exclusive optional trigger" (so you can use a Lead Bullet handgun in the left hand and another Trigger in the right hand). The demerit is that the cost of a magazine is high, and the number of bullets are limited. Other gun Triggers can also use it if they are customized.

Q: Can motorbikes or cars run on trion energy? A: If HQ were to develop a "car-shape Trigger that runs on trion" then it’s possible. There is already a mechanism that converts trion into electricity, so I think electric automobiles can naturally run off it, but It wouldn't be very efficient, due to high energy loss.

Q: Do Black Triggers not come with communication abilities or Shields? A: It’s different depending on the Black Trigger. For instance, Fūjin doesn’t seem to have Shield but looks like it has communication abilities (a receiver sometimes being there, sometimes not is Ashihara’s mistake). Yūma's Black Trigger doesn’t have communication abilities but Replica was responsible for that role.

Q: Are there people who have resigned from Border? And is that possible? A: There are times when agents or staff leave Border due to career or family matters. To quell confidential leaks, measures might or might not be taken to seal memories depending on the kind of person who’s leaving. For instance, if Taichi were to leave, I think his memories would probably be sealed.

Q: What happens if you Bail Out inside Border HQ? Do you fly outside first and then fly back to HQ? A: Inside the HQ base there are ducts for Bail Out use, so you will return to your operation room through those. You don’t need to go outside.

Q: It’s said that Jin made Scorpion, but are there any conditions for an agent to take part in Trigger development? A: Kako talked a little about it in Volume 14; when you become A-rank agent, you can make requests with Engineers to customize your Trigger. Developing new Triggers is just an extension of that.

Q: Is there a large age difference between Utagawa and his older sister? A: It does seem like there is.

Volume 19 - Question Corner 13
Q: Does Miwa have a sword or gun mentor? A: He started using handguns as a countermeasure to getting beat up by Tachikawa, so in a way you can’t not say Tachikawa is his mentor.

Q: Is there anyone with a Side Effect among the Operators? A: There is. I think I will get to draw it at some point.

Q: How is Starmaker used during normal defense duty or in rank wars? A: Mostly as a countermeasure for stealth. Even a graze will let you mark that section, and as long as it’s not cut off then you can make Chameleon or Bagworm temporarily rendered useless. Its weaknesses are that it’s an all-purpose option so it can’t be used with Full Attack, and usually you defeat the enemy before they even get marked.

Q: In Volume 8, if Chika temporarily linked with Izumi instead of Osamu, what would happen to the power of the Asteroid? A: Chika's burst of Trion would've been the same, so the attack would be identical to Osamu's. if they'd been going for pure power, having Osamu and Izumi hold hads would've produced the biggest, flashiest attack of all.

Q: Who brought the Rilienthal plush that was in Osamu’s hospital room in Volume 10? Was it Yōsuke? A: It’s a toss-up between Yōsuke and Usami, but it feels like it was Yōsuke.

Q: Were the snowmen in Chapter 115 made by Ninomiya himself? A: He made them industriously himself. It was in plain sight of the commentating seats.

Q: Why did Konami and Kitora have different uniforms, despite the attending the same school? A: Because Konami is in high school. Kitora will get the same uniform when she enters the High school division.

Q: The boy’s uniform for the normal high school is a gakuran, right? Is the girl’s sailor fuku? A: It’s sailor fuku. White short sleeves in summer, navy long sleeves in winter, white long sleeves in spring and autumn.

Q: What was going through Kazama's mind when Mikumo's mom mistook him for a middle-schooler. A: "I thought she was his older sister so we're even."

Volume 20 - Question Corner 14
Q: You had a character whose name means ‘pig’ in your last work (Schwein), and in this one Hyuse means ‘pig’ too. Is there some kind of meaning behind this? A: There isn’t really any meaning, but since the author likes pork cutlets he might be subconsciously giving the title of ‘pig’ to characters.

Q: What are the criteria used to choose who does the Play-by-play and the commentary for rank wars? A: It seems Play-by-play are mostly those who have A-rank experience, but sometimes B-rank captains are called up too. Anyone can be a commentator as long as they can talk, and honestly it doesn’t have to be an operator but because you need to operate equipment a lot are Operators. There have been times when the person doing the Play-by-play was a combatant or an Engineer.

Q: Kako-san doesn’t have a Gunner Trigger on her main Trigger side, so why is she a Shooter? A: This comes from BBF. Thank you for reading. The positions are based on the equipped Trigger with the most solo points (except All-rounders). Kako-san’s Hound (custom) that she equips in her sub has the highest solo points, and the Scorpion she equips in her main hasn’t reached 6,000 points yet, so she’s a Shooter. It looks like she wants to increase her Scorpion to over 6,000 points and become an All-rounder. In the Galopoula battle, it seems she equipped Hound (custom) in her main too in preparation for a firefight.

Q: Can Enedora’s ‘Vorvoros’ make things like just his hand from a distance? A: It seems possible, but it seems he can’t make precise movements. But it’d likely be interesting if he could move it.

Q: If Mira closes one of her portals around an object, would the object cut in two? Or would the portal just be unable to close. A: No cutting, The object would just be forced out of the portal, like "pop". If the portals were capable of cutting thing and people in two, there would've already been a number of unfortunate accidents.

Q: Can Hyrein’s ‘Alektor’ create bullets in the shape of humans? A: It doesn’t seem like there are bullets of mammals that don’t reproduce through ‘eggs’, but he was using things that looked like jellyfish which goes planula larva -> polyp strobilation, so maybe he can.

Q: Can ‘Alektor’s’ ability to take in trion from surrounding cubes and heal the user be used on other people’s trion bodies? A: He didn't do it for Mira, so it seems it can’t.

Volume 20 - Question Corner 15
Q: Is there anyone of 18 and above who has a driver’s licence for a car or a bike? A: Aside from Reiji who has already driven in the story, it seems Fuyushima, Azuma, Suwa, Tsutsumi, Kako, and Kakizaki have normal driver’s licenses. The top brass and Sawamura have licenses too. Tachikawa doesn’t as you might expect. Zoe has a motorbike license, and Kage and Touma have motorized bicycle licenses (two wheelers under 50cc, Scooters, mopeds etc). It seems Arafune and Hokari want motorbike licenses too.

Q: Konami is the no. 3 Attacker, does this mean she shows up in the solo rank wars? And in that case what Triggers does she use? A: Studying came first for Konami up until the end of her middle school years so she didn’t do any solo rank wars then, and only participated in the period from her middle school graduation and part way through her first year of high school. Back then, in that period, Jin started using Fūjin and Tachikawa had kind of lost his motivation, so Konami sharpened her blades against those like Kazama to reach all the way to Attacker rank no. 1. After that, along with Tamakoma’s separation, she took a step back from rank wars, but her solo points have only been surpassed by Tachikawa and Kazama so she’s still Attacker no. 3. Her Triggers at the time were dual-wielded Kogetsu (fairly short).

Q: Can the things on a Trion Body like the clothes you’re wearing or shoes be taken off? A: There are settings that allow that, and settings that don't. Not allowing it saves on Trion costs since constructing the body is simpler. For official Border purposes, the standard setting only allows one to remove outer wear, but nothing else.

Q: Does Jin use his Side Effect in solo matches? If he does, then what is the cause when he loses? A: It seems he uses it against A-rank agents. He used it actively in his past matches with Tachikawa too. A common case of him losing has him getting absorbed in reading the future and neglecting the present as the main factor.

Q: Up to the Large Scale Invasion Arc, Hound was written with the kanji for "Guided Bullet", but from rank wars it’s written with the kanji for "Tracking Bullet"; why is this? A: "Detection guidance" which chase trion responses is written "Guided Bullet", and "Visual Guidance" which locks on to the target with line of sight is written "Visual Guidance", but there are quite a few mistakes here and there so don’t worry about it.

Volume 21 - Question Corner 16
Q: What would happen if Chika used Spider? Could she make a giant spider web all at once? A: She could bust out one hundred times as many wires as Osamu in one go, but they'd be so dense they'd immobilize her, and they'd end up stabbing her and her allies.

Q: Does Kageura wear a mask in order to hide his sharp spiky teeth? A: There's that, yes, but it's also to cover up more skin, which keeps his side effect from taking too much of a toll on him.

Q: Why would anyone ever recruit Taichi Betsuyaku? A: For his youth, his decent Trion levels, his excitability and his dazzling eyes.

Q: Please tell me Tsuji's brothers' names. A: His older brother is Ryōtarō, and his younger brother is Sōhei.

Q: If Tsuji is so awkward with women, why didn't he go to an all-boys school? A: Because he needed to train his heart to cope.

Q: When will Suwa get a Black Trigger? A: Who knows? The future is vast and limitless.

Q: What do Trappers do, exactly? Do they forgo weapons altogether and just set traps? A: Yes, they're dedicated to traps. The Switch Box trigger used by Trappers is not only tough to use, but it consumes a huge amount of Trion, so for the most part, Trappers don't equip ordinary attacking triggers.

Q: If someone tries removing the trion gland from a body, wouldn't they run into a wall of meat and bone? Is it possible to rip out the trion gland without killing the subject? A: It's believed to be impossible with current technology. But surgically removing Black triggers might be possible?

Q: Can other people not use Tamakoma First's triggers? A: Sure, they can, but Tamakoma's triggers are advanced enough to be hard to handle for the inexperienced. That said, Arashiyama could use Geist, Nasu could use Axe, and Iko could use Full-Arms.

Q: Half a year before the story started, Rinji was 20 years old, but was he in the same grade as Ninomiya? Or the same grade as Kazama? A: Same grade as Ninomiya. Maybe they kept passing by and missing each other in high school and college?

Volume 21 - Question Corner 17
Q: What were Ikoma Squad and Ōji Squad doing when Galopoula showed up? I guess they were off duty? A: In Chapter 124, when Shinoda said, "Leave one squad in the west and one in the south," that was those two.

Q: Of all the nicknames Ōji has given people, what are his top three? A: He doesn't think too hard about them. He just sort of comes up with them in a very Ōji-esque way. Two that have become popular are "Mikamika" and "Pokari," and the one that's spread the least is "Jackson" for Wakamura.

Q: When someone is using a Trion body, can they take off their clothes and shoes? A: There are settings that allow that and settings that don't. Not allowing it saves on Trion costs since constructing the body is simpler. For official Border purposes, the standard setting only allows one to remove outerwear but nothing else.

Q: What do the other agents think about Ōji's nicknames for people? A: "As long as we can figure out who he's talking about, it's whatever." Except in the case of Wakamura.

Q: What sort of gifts are you happy to receive? And which ones, not so much? A: When I was hospitalized, I hated the flavorless rice gruel, so I got a lot of use out of the bottled seafood preserves sent to me by fans (with hospital permission, of course). There's no gift I wasn't happy to receive, though the editorial staff wouldn't let me eat homemade food from fans, as a rule.

Q: During the Galopoula attack, Kuruma mentioned how leaders are usually determined by rank or age, but are there more formalized military ranks for individuals in Border (like sergeant, colonel, etc.)? A: Since the organization is still pretty small, different agents' duties don't differ that much. Besides Commander, HQ Director, Branch Director, and squad captains, there are no individual ranks. Also, because Border is a civilian organization, they're wary about pushback from the government and populace in general if they were to implement more of a military-style hierarchy.

Q: Does the Internal communicator function transmit all of one's thoughts? Or just the thoughts that one wants to broadcast? A: The latter. It won't transmit unless you have a recipient in mind and put those thoughts into clear words.

Q: Satori's ultimate move isn't "Double Snipe," but rather "Twin Snipe". Any special reason for that name? A: Satori once played a video game that had a weapon called "Twin Cannon," and that's where he got the name.

Q: Please tell me why Satori chose to be a sniper. A: So that he could help people over the widest range possible.

Volume 23 - Question Corner 18
Q: Are there any other siblings within Border other than the Kazama brothers? A: In terms of characters who've appeared already, there's Tsukimi's little sister and Zoe's little brother, both of whom are in Yoshizato Squad (B-rank).

Q: Why do so few agents choose to wield teleporter? Is there some downside to using it, like not being able to use one's Triggers within a certain range immediately after, or one's body freezing up? If not, that seems like an overpowered Trigger. Also, why didn't Arashiyama Squad wear goggles during the scramble for the Black Trigger? Concealing their lines of sight would've been a big advantage. Is it because that was their first time using Teleporter in a real battle? Or was it because they were purposely getting Toma to shoot? If there's no downside beside the line-of-sight thing, then I think Teleporter is way to powerful. A: Ah, you're a Teleporter diehard. Thank you for the question(s). Given Izumi's shock when Arashiyama used Teleporter in volume 4, it's safe-ish to assume that was his first time using it. Kako Squad–the first Teleporter users–had a reason for not wearing goggles (which could hide one's line of sight), but if Arashiyama had worn goggles after his first use of Teleporter revealed the trick, I bet that would've made him really strong. I also tend to think that Teleporter is ridiculously powerful, but there are downsides, and learning to use it properly takes a high level of skill. I'm hoping to elaborate on that with future battle scenes involving Kako Squad, so please be patient.

Q: Can Yūma's side effect help him detect lies in writing too? Like in books or text messages? Will Yūma's side effect pick up on lies that the speaker doesn't even realize are lies? How does Yūma's side effect tell him when something is a lie? (Does he hear the person speaking in slow motion, or does he get prickling tingles like Kage?) A: When a person is lying, Yūma's side effect makes it look like black smoke is pouring out of their mouth. The subtle changes in the liar's voice transform into a visual cue that helps Yūma see through the lie. So no, I don't think his side effect would work if the person didn't know they were lying or if he were reading the lie in a text.

Q: At the start of round 7, Kage used Scorpion to swing across a big gap. Is Scorpion really strong enough to carry the weight of the person who's manipulating the blade's shape? A: Weapons made of Trion are super-strong, even for non-attacking purposes. Definitely sturdy enough to do the job.

Q: The engineers who created the round 7 map are incredible. Do they replicate every little detail of the areas of Mikado City right down to the wiring? A: They're using technology that scans the real-life buildings and components of the city and replicates them all in the virtual space. For that night map, the engineers took the time and effort to faithfully upgrade the data on the electrical system.

Volume 23 - Question Corner 19
Q: Can a Sniper Trigger shoot anything besides Asteroid or Lead Bullet? A: Strictly speaking, a sniper's "bullets" aren't Asteroids, but sure–I bet they could make a special request to the engineers. However, the result would have reduced power, speed, and range, making the shots easier to block. It might be fun to have them shooting Viper shots, but nailing a far-off target would be pretty difficult.

Q: Who came up with the "Torimaru" nickname? A: It started up as a slip of the tongue by Tachikawa, but it seems as though Konami jumped all over that and spread it around. These days, Tachikawa calls him by his given name, "Kyōsuke" with a straight face, accepting no blame.

Q: Please tell us Hyuse's birthday. A: Translated to a date understood by our world, it would be June 12. His zodiac sign is Lepus.

Q: Did Yūma's Black Trigger have no seals initially? Please let us know if there were any standard seals? A: He started with Seven altogether, including Bound, Boost, Shield, Chain, and Echo.

Q: When the Escudo popped out of Murakami's body, did it feel heavy to him like a Lead Bullet? Or did it just impede his movement because of the bulk? A: I think it's got to be lighter than a Lead Bullet. But since it's such a stiff hindrance, one could use that move to really annoy people.

Q: Is Ōji at an ordinary school because he's not great at schoolwork? A: Ōji used to have much more of an edge to him, so it's possible he bungled the interview and failed to get into the school of his choice. I think his grades are decent enough.



Q: When Ōji mentioned how it was the first time his squad got ahead of Yuba Squad, Yuba's face was covered by the speech bubble! How did he react to that line from Ōji? A: He LOL'd, maybe? I guess.

Volume 24 - Question Corner 20
Q: Tokieda and Satori joined Border at the same time, but were they friends before that? Or did they become friends after joining up? A: They'd known of each other since elementary school, but it wasn't until middle school that they ended up being in the same homeroom class and became friends. Then they joined Border together.

Q: What's the breed of dog at Yōsuke's house? A: Black Shiba Inu. It's technically Yoneya's grandma's dog.

Q: Is Izumi a dog person or a cat person? A: His vibe screams "cat person".

Q: When Tachikawa Squad was being formed, did Tachikawa scout Izumi? Or did Izumi ask to join? A: Tachikawa really wanted to battle the previous iteration of Azuma Squad, so recruiting Torimaru and Kunichika was just a pretext for that. The old Azuma Squad disbanded shortly after that.

Q: What are the names of Hanzaki's siblings? A: The older brother is Takato. The younger sister is Minato

Q: Please tell us Izumi's older sister's name and age. A: It's Eiko, and she's 23 years old.

Q: When Hyuse is using his Trion Body (without horns), does he sleep facing up? A: He's attempted it when he had Trion to spare, but before he knew it, he had flipped facedown again. Old habits die hard.

Q: What would happen if someone combined Meteor with Lead Bullets? A: Anyone caught in the blast would be covered in a thin but weighty layer of lead. They'd feel slightly heavier, but when they moved around, it would crack and fall off.

Q: In the Volume 23 bonus content, Suwa's comment about Kazama was, "Depressing, nasty personality." Did he come away with that impression after a particular incident? A: No specific incident—they just don't get along.

Q: After falling to B-Rank, did Ninomiya Squad and Kageura Squad challenge and lose to A-Rank Squads during the Rank Wars in October? Is that why they've remained B-Rank? A: After dropping down in the ranks, they couldn't fight for a chance at promotion for a set period of time as a penalty. Something like that.

Q: If a single agent decided to quit in the middle of the Sealed Environment Phase of the test, would their whole squad be disqualified? A: According to the rules of Phase 1, no—the team would not be disqualified. They would just continue the test with fewer people. Still, that would leave them unable to gain as many points as other squads, so it would be mighty difficult to reach the top of the test rankings.

Q: Most of the female characters have three distinct eyelashes over each eye, so why does Ui only have two? A: The leading theory is that Ui donated a pair of lashes to Fumika Teruya.

Volume 25 - Question Corner 21
Q: Why does the Trion amount increase when using a Black Trigger? A: It's probably because the Black Trigger's creator's trion is added. It seems like the output is higher than what the creator originally had, perhaps because the Trion poured is crystalized at the time of creation

Q: Who does Nasu-san get along with outside her squad? A: For the boys, it's her cousin Narasaka, his disciple Kodera, somehow Kitazoe, and Utagawa who is good friends with Kumagai. For the girls, it's Teruya, Konami, An Kobayakawa, Tsukimi's younger sister Hanao and some others from the Seirin Girls Academy, Risa Maki who likes movies, and others.

Q: Could you please tell us the name of Akane's brother! And, did they manage to confess to Kumagai before they moved away? A: His name is Shōma. I don't think he managed to confess. If he had, the farewell scene with Nasu squad would have been awkward.

Q: Hatohara-san once shot someone and fell ill, who did they shoot? A: She involuntary shot Utagawa while he was using Chameleon. After that, she practiced so she could snipe while also paying attention to the radar.

Q: Who was the Operator of Former Azuma Squad (Ninomiya/Kako/Miwa)? A: It's Tsukimi.

Q: I heard that Izumi was the only one who could challenge Ninomiya. If they fought, would his master, Izumi, win? I would like to know the winning percentage! A: I think Ninomiya would win about 60% of the time in a one-on-one match. In a team fight, Tachikawa Squad would win by a wide margin, in addition there were many occasions when Izumi beat Ninomiya.

Q: Did Shiki-san of Nasu Squad become an operator because she is not good with men? A: I think it's because I'm not good at jumping and running.

Q: Would Arafune be afraid of Raijinmaru if she were introduced as a dog? A: I would say, "It looks like a rodent," but if someone said, "This one bites ......," I think I would brace myself.

Q: Was Raijinmaru present when Yōtarō was born? A: Raijinmaru was not born until after Ruka and her family had defected to Meeden, which is a little later than Yōtarō's birth.

Volume 25 - Question Corner 22
Q: I would like to know the rankings of the Gunners and Shooters like we do with the Attackers and Snipers. A: From what I remember, The top 3 Shooters, from the top, are Ninomiya, Izumi, and Kako. Top 3 Gunners are Kazuma, Yuba, and Katagiri Top 3 All-Rounders are Reiji, Arashiyama, and Miwa.

Q: Why does the gentle and friendly Tonooka have a punk haircut? A: "Tono is plain and is hard to find (in rank wars)" Koala's sigh of defeat was taken seriously by Nono "He's not plain, he's skilled!" And she made Tono flashy, which was very well received and became the norm.

Q: Was the "Bailout" developed by Galopoula created from scratch? A: It was developed after receiving information on Meeden from Afto, but the gate technology was already developed before. Like Border's Bailout, it eats up a lot of Trion just to set it up and it seems to be unpopular with Reghi and some others.

Q. What's Miwa's, Ninomiya-san's and Kako-san's favorite part of the Yakiniku? A: Miwa mainly likes the skirt meat and ribs, but is generally okay with anything, Ninomiya likes the shoulder loin and hip meat, and Kako-san likes the tongue and rump. Luxurious.

Q: Why do Shooter cubes have different shapes like squares and spheres? A: Probably because they want to control the number and power of the bullets in detail. It seems to be a very advanced technique to divide the cube into shapes other than more cubes. Izumi could likely do it too, but he isn't so particular about the shape.

Q: What's Tsuji's favorite dinosaur? There was something that looked like a Plesiosaur in Ninomiya squad's strategy room, does he like Paleontology other than dinosaurs? A: He likes the the most. He also likes marine reptiles such as the and the.

Q: Can you use Teleporter even if there are obstacles between you and the location you want to move to? A: No, it can't be used if there is no line of sight to your destination, so it can't be used if there is an obstacle, if your eyes are blocked or if there is a smoke screen.

Q: Does it hurt if you pull or push on Hyuse's horns? A: The area of the base of the horns and his head shouldn't hurt much, but if you move them around a lot it will hurt his neck.

From Twitter - April 2014
Q: If you become B-rank or A-rank do you have to join squads? (I want to read about the stories behind all the squads’ formations) A: To participate in rank wars, at the very least you need one combatant and one operator. Naturally, it’s more advantageous to have more members, so a squad with few members is quite a thorny path in comparison.

From Twitter - January 2015
Q: When enemies show up on Radar, is it possible to use that to snipe? A: Compass points are displayed on Radar, but not elevation, so it seems impossible. Combined with the topography data that operators have, it is possible to grasp the approximate location of the mark, but it would be hard to pinpoint a human-sized opponent this way.

From Twitter - February 2015
Q: Are Radars and wires Optional Triggers? A: "Radar" is a Standard Equipment Trigger like trion bodies or the Bail Out function. "Spider", a Trigger that uses wires, is an Optional Trigger.

Q: Is Kunichika from Hokkaido? (trans: a reference to the fact that her favourite food is ishigari nabe/salmon hotpot, a traditional Hokkaido dish) A: Her mother is. Her parents would send salmon hotpot sets, sea urchins, crabs, salmon roe and so on to them. Everyone eats them together.

From Twitter - August 2015
Q: Why do Arashiyama and his siblings have ‘second position’ type names? A: The person who named them, Arashiyama’s grandfather, apparently had something in mind when he chose them, but since he has passed away nobody knows for sure. The three of them seem pretty happy with it.

Q: How many Mini-Replicas can be released at a time? A: If the functions are limited to conversation and transmitting over the comms he can probably release about 200 of them

From Twitter - September 2015
Q: While you are in your Trion Body, where is the Trigger Holder that houses your flesh body? A: In another dimension (a dimension in the Neighborhood) an independent space has been set aside for the Trigger Holder to be stored.

From Twitter - June 2019
Q: In the manga volume of "Jujutsu Kaisen," announced the image songs for the characters; do World Trigger characters have any songs like that? A: Right now, only Yūma has a song connected to him. It’s Dash Through the Night (を ける) by Spitz.

July 7th
Q: In Chapter 222, Mizukami and Kon seemed to get along very well. Are they involved in more than just being in the same grade? A: I don't know if they are close or not, but both of them have excellent grades, so they may have been treated as one by their school.

Q. Kunichika calls Konami, Kitora and Katori by just their last name. Is this because they are younger or is there another standard? A: Perhaps it's a defensive instinct, to call those who are younger or the same age but who seem to be smarter than you like that. Only Kon, who has helped her with her studies, gets called "chan" or "sama".

Q. How does Jin's Side Effect work? Can he turn it ON or OFF? A: It's like having a new window open up in your vision (mind), you can't turn it off, but you can consciously choose to ignore it. The person you saw once gets registered in the brain channel for a while and seems to allow tracking future branching events during it.
