    World Trigger Wiki

    This article is about the character. For other uses, see Yūichi Jin (disambiguation).

    As you well know, I have the Side Effect of foresight. I had seen multiple futures during the Large-Scale Neighbor Invasion. So when I found out they wanted to capture agents, I could've let Chika escape early on. But I didn't do that. The more the enemy focused on Chika, the less likely they were to damage the city. It worked out well in that respect, but you almost died, and Professor Replica's gone. So it's my fault. It wasn't yours at all.

    Yūichi Jin to Osamu Mikumo, in Yūichi Jin 9.[1]

    Yūichi Jin ((じん) (ゆう)(いち), Jin Yūichi ?) is an A-rank (formerly S-rank) member of Border, and a member of the Tamakoma Branch. He is one of the main characters of World Trigger[9] and the tritagonist of the series. He is also one of the twelve candidates for the Black Trigger Fūjin and is the most prominent user.

    Appearance[edit | edit source]

    Jin has combed brown hair and blue eyes. He wears a pair of turquoise tinted sunglasses, usually held around his collar.

    He is always wearing his Border uniform, a blue jacket with a long black stripe going down the middle of each sleeve over a white shirt, and the Tamakoma Branch's emblem on his jacket's upper sleeves. He also wears dark brown pants and black boots.

    Personality[edit | edit source]

    Jin has a laidback demeanor, even in situations when he is called out for being antagonistic, such as hiding and protecting a humanoid Neighbour[10]. His favorite food being rice crackers, he always has a bag in his hand wherever he goes, offering some to everyone, even people he once fought with. Despite losing his mother to a Neighbor, he believes that not all Neighbors are inherently bad. In fact, he thinks humans and Neighbors should get along, believing that both races could co-exist[11]. Jin always acts like a carefree person, but in order to protect his friends from being threatened, he shows a more serious side[12]. Even then, he tends to hold back, showing no desire of harming his foes unless they force him to.

    Despite his lighthearted behavior, Jin is one of the most clever and influential agents in Border. He is shown to be very resourceful and good at "pulling strings" with his Side Effect, which gives him the ability to see the possible futures of the people around him[13]. He often uses any advantage or piece of information he has to obtain objectives for the sake of others, especially his comrades. Jin's amiability and high rank makes him popular and well-known among Border members and counts as another advantage, given all the networking and connections he needs to get things done. This was best seen when he was able to get the help of numerous Border members and captains to search for and destroy the thousands of trion drones that were causing irregular gates to open[14]. He usually refers to himself as the "power elite", although it is implied he is the only one who does.

    Quotes[edit | edit source]

    • (To Osamu Mikumo) "Hey. You alright, Four-Eyes?" [15]
    • (About the future) "Not just victory and defeat decide the future." [16]
    • (To Osamu Mikumo, about Aftokrator's Invasion) "As you well know, I have the side effect of foresight. I had seen multiple futures during the Large-Scale Neighbor Invasion. So when I found out they wanted to capture agents, I could've let Chika escape early on. But I didn't do that. The more enemy focused on Chika, the less likely they were to damage the city. It worked out well in that respect, but you almost died. And professor Replica's gone. So it's my fault. It wasn't yours at all." [1]

    Trivia[edit | edit source]

    • "Jin" ( ?) means swift, while "Yuichi" (悠一 ?) is made up of the symbols for permanence, and one.
    • He likes Bonchi rice crackers (which he is frequently seen eating and sharing with others), women's butts, and working behind the scenes.[17]
    • He came 5th in the first of the World Trigger Character Popularity Polls.
    • When around Border agents, Jin is always in his trion body to reinforce his “talented elite” image.[18]
    • If you steal and eat Jin's rice crackers, he will send a whole box of them to your room without permission.[19]
    • Due to brand issues, Bonchi rice crackers are changed to the generic agesen (lit. fried rice crackers) in the anime.
