    World Trigger Wiki

    Background[edit source]

    Mizukami hails from Ōsaka. As a child, he was a prodigy at Shōgi and was on track to become a professional player until middle school.[1] He was eventually scouted by Border.[2]

    Introduction Arc[edit source]

    Ikoma Squad presumably takes part in the extermination of all Rads in Mikado City.[3]

    Large-Scale Invasion Arc[edit source]

    Ikoma Squad is seemingly not deployed during the Second Large-Scale Invasion, and could, therefore, be among the B-rank Squads with missing members which Masafumi Shinoda prevents from fighting against Aftokrator's forces out of fear of capture.[4]

    B-Rank Wars Arc[edit source]

    Round Two[edit source]

    On February 5,[5] Ikoma Squad faces off against Ninomiya Squad in the second round of rank wars.[6] Since Azuma Squad, Katori Squad, Ōji Squad and Yuba Squad[7] compete in a four-way match in the day division,[5] it can be inferred that the three-way battle takes place in the night division and that Kageura Squad is the third participant.

    Round Four[edit source]

    Since Tamakoma Second fights Ninomiya Squad, Kageura Squad and Azuma Squad in the night division of rank wars on February 15,[8] and since Katori Squad and all other possible opponents were in the middle tier of B-rank or lower,[9] Ikoma Squad must have fought in the day division against Ōji Squad and Yuba Squad. After the scores from both divisions are tallied, Ikoma Squad remains in third place[10] with 24 points.[11]

    Galopoula's Invasion[edit source]

    Since Azuma Squad, Kageura Squad, and Yuba Squad fight in the night division of rank wars on February 19,[12] Ikoma Squad must have competed in the day division against Ninomiya Squad, Ōji Squad and Suzunari First. They rank third at the end of the match.[13] That same night, Ōji Squad and Ikoma Squad are deployed to intercept opponents west and south of the base in preparation of Galopoula's Invasion.[14][15]

    Round Five (Night)[edit source]

    After the results of both the day and night divisions are tallied in round five, Ikoma Squad ranks third, with 27 points.[16]

    Round Six[edit source]

    Ikoma Squad is pitted against Ōji Squad and Tamakoma Second in round six. On the day of the match, the team members are gathered in the strategy room, discussing Tamakoma Second's prowess. Mizukami is particularly worried by the wire strategy. After Kōji Oki points out that Maori Hosoi seems to resent not being complimented, Mizukami joins Tatsuhito Ikoma and Kai Minamisawa in singing her praise. He then reviews how they can counter Chika Amatori's Lead Bullet, and tasks Oki with taking her out.[17] The conversation moves to the menu of the cafeteria until the start of the match.[18]

    Mizukami spawns in the western portion of Cityscape A and quickly meets up with his captain. When Yutaka Kashio dons a Bagworm, Mizukami surmises that he must be looking for Chika or Osamu Mikumo, who is also off-Radar, so he warns Minamisawa about the possibility of a sneak attack.[19] As Minamisawa engages Kashio, Ikoma and Mizukami start heading towards him, but he bails out before they can reach him.[20] Ikoma launches his signature Senkū attack, which all of Ōji Squad and Yūma Kuga survive. Mizukami thinks it a fluke and tells him to try again, but they all dodge again and Yūma escapes. At Ikoma's behest, Mizukami targets Kazuki Kurauchi with a Hound volley disguised as Asteroid, although Kazuaki Ōji sees through his deception and warns his teammate in time. The Shooter is however beheaded by Yūma with a sneak attack, so Ikoma and Mizukami shift their attention to Yūma. When Chika takes a shot at them, they pressure Oki into making more of an effort.[21]

    It is not long before the Sniper is found by Ōji, so Ikoma and Mizukami make their way towards him while fighting Yūma.[22] As both the Tamakoma Second ace and Chika reach the wire zone, she proceeds to raze the buildings around Ikoma and Mizukami, who follow their target into their turf.[23] Mizukami recommends attacking from a distance as they cut down the wires until Oki snipes Chika. However, he is hit by her Lead Bullet when Yūma stuns him with a piece of debris, and immediately beheaded by Ōji's sneak attack.[24] The match terminates not long afterwards, with Ikoma Squad and Ōji Squad scoring three points against Tamakoma Second's four.[25] After the results from both the day and night division are tallied, Ikoma Squad remains in third place with a point total of 34.[26]

    Round Seven[edit source]

    Since Tamakoma Second faces off against Kageura Squad, Azuma Squad, and Suzunari First in the day division of rank wars on March 1,[27] it can be inferred that Ikoma Squad competes against Ōji Squad and Ninomiya Squad in the night division. After the results of both the day and night divisions are tallied, Ikoma Squad ranks fourth.[28]

    Round Eight[edit source]

    On March 5,[29] Ikoma Squad is pitted against the Ninomiya Squad, Tamakoma Second, and Yuba Squad in the night division of rank wars. The fighters are as relaxed as ever, listening to Ikoma's rambling stories.[30] Mizukami spawns in the center-northern area of Cityscape B. As he begins to move eastward, his attention is soon caught by a bombardment in the west, which he supposes to be Masataka Ninomiya's doing.[31] The Trion signature on which members of multiple teams converge disappears, but Oki is able to spot its owner, Hyuse, and they decide to target him.[32] As Takuma Yuba, Yukari Obishima and Sumiharu Inukai also join the fray, Mizukami monitors the fight while keeping Hyuse penned in.[33] He is briefly distracted by a massive explosion caused by Chika's Meteor misfiring. Hyuse manages to hold off the close-ranged fighters, but Inukai and Mizukami stop him in his tracks as he attempts to flee.[34] Mizukami is surprised by Hyuse's presumed Asteroid turning out to be Viper and forcing Ikoma to bail out. The remaining bullets turn towards Minamisawa, but Mizukami Shields him, so he is able to deliver the final blow. As Hyuse bails out, Mizukami finds himself pincered by Yuba and Inukai. Unable to guard against both their attacks, he is defeated by the enemy captain.[35] When Oki snipes Kazuto Tonooka, Mizukami protests that he could have used his skill to help them, but the Sniper replies that everyone else was ready to defend.[36]

    The match ends with Ikoma Squad and Yuba Squad tied in third place, having scored two points each.[37] When the final commentary does not answer his questions about Hyuse's ability to dodge his first Senkū, Ikoma turns to Mizukami, who explains that their movements confirmed that their movements and numbers tipped him off. The season of rank wars ends with Ikoma Squad ranking fourth, with a total of 34 points.[38]

      A: It seems I lost the chance to draw it in the story itself so I'll write it here: "HQ Chief Shinoda gave the order that B-rank and lower agents are not allowed to participate in the fight until all members of the team are present". It seems he was worried about agents acting on their own and getting captured by Rabbits. Of course, there are also teams like Kako Squad who was late to the fight because their captain went out on a drive on her time off.
