Wataru Urushima Position: Gunner Age: 16 Birthday: December 28 Height: 166cm Blood Type: A Zodiac: Horologium Occupation: High School Student Likes: Tamago kake gohan, taiyaki, saving money Family: Father, mother, older brother Gunner and Captain of B-Rank Rank 14 Urushima Unit. 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. This is mainly because B-Rank pay is performance-based, and he frequently steals kills by taking down Trion soldiers that others were targeting. Regarding this, he remains unrepentant, coolly stating, "It's your fault for being too slow." Despite being a Gunner rather than a Sniper, he equips Bagworm during defense missions where it isn't strictly necessary, suggesting he is a calculated offender. On the other hand, he sent an email to Kodera—the captain of the squad Rika Rokuta was assigned to during the Away Mission Selection Test—asking him to look out for her because she struggles with parallel processing. He has a relatively good relationship with Yuma, having held a post-battle review while cooking together. He seems capable of showing appropriate consideration toward women. Main Trigger / Sub Trigger Asteroid: Assault Rifle / Bagworm Chameleon / Silencer Shield / Shield Dummy Beacon (Prototype) / Meteora He is quite strong. A first-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 profit-driven motives, choosing realistic and harsh words centered on rewards, such as "There's no profit in this" or "It's more lucrative to go on defense missions." He often speaks in a listless, blunt, and monotone voice, but in crucial moments, he makes sharp remarks that cut to the heart of the matter. He is frank even with superiors, showing little respect or amiability, and often treats older people or those he meets for the first time with a flat, slightly mocking attitude.
