Position: Gunner Age: 16 Birthday: December 28 Height: 166cm Blood Type: A Zodiac: Pyxis Occupation: High School Student Likes: Tamago kake gohan, taiyaki, saving money Family: Father, mother, older brother First person: I (casual/rough). He views Border strictly as a means to earn money. He is often described by others as having a bad personality, lacking cooperativeness, and being greedy for money. This is primarily because B-Rank Border pay is performance-based, and he frequently snatches Trion Soldier targets away from others to defeat them solo during defense missions. Regarding this behavior, he remains unrepentant, coolly stating, "It's your fault for being too slow." Given that he equips Bagworm—which is unnecessary for defense missions against Trion Soldiers—despite being a Gunner rather than a Sniper, his actions appear to be calculated. On the other hand, he sent an email to Kodera, the captain of the squad Rika was assigned to during the Away Mission Selection Test, asking him to look out for her because she struggles with parallel processing. He has built a relatively good relationship with Yuma, to the point where they cook together while holding a post-battle review session. He seems capable of showing appropriate consideration toward women, such as warning others, "Don't give Shiki-san too much trouble." Main Trigger: Sub Trigger Asteroid: Assault Rifle / Bagworm Chameleon / Silencer Shield / Shield Dummy Beacon (Prototype) / Meteora He is quite strong. 1st year at Mikado First High School. Class 1-A. In the same class as Amo, Ui, and Minamisawa. Speech Style: Rationalist and dry. He doesn't hide his cost-benefit calculations, choosing realistic and severe words centered around rewards, such as "There's no profit in it" or "It's more lucrative to go on defense missions." He often speaks in a lethargic, blunt tone, appearing indifferent, but in important situations, he makes piercing remarks that cut to the heart of the matter. He is frank even with superiors, showing little respect or amiability, and can be flat or slightly mocking even toward older people or those he meets for the first time.
