Yusa Arima (有馬 夕作, Arima Yusa) is a former ghoul investigator and alumni of the Sunlit Garden. He served as one of Kishou Arima's personal squad until his defection at Cochlea. He and his squad now serve as one of Ken Kaneki's bodyguards.
Yusa is a slight boy with short, wavy black hair. He is typically dressed in the white trench coat worn by all members of his squad.
Yusa is a gentle and mild-mannered boy, often acting as the voice of reason within his group. He enjoys fantasizing and daydreaming, and hides an interest in learning about the outside world and things not pertaining to fighting.
Third Cochlea Raid Edit
Yusa along with the other members of the Arima Squad was tasked to protect Cochlea and later encountered Ken Kaneki beside Arima's corpse. After being granted permission to say their goodbyes to their late squad leader, they gathered around his body and cried over his death.
Yusa and the rest of Squad 0 followed Kaneki deeper into Cochlea and encountered Eto Yoshimura who was critically injured on the floor. Moments later, Squad 0 interrupted the fight between Kiyoko Aura and Mougan Tanakamaru against Touka Kirishima, Ayato Kirishima, Renji Yomo, Kazuichi Banjou, and the members of Banjou's crew.
Post-Third Cochlea Raid Edit
Clown Siege Edit
Yusa and the rest of his squad respect and look up to Kaneki as Arima's successor. They call him by his name as an investigator. Kaneki acts very kind and fatherly towards Yusa and his squad, even cooking food for them like he once did for his former "kids", the Quinx Squad.
Hirako says that Arima was hope itself to the children of the garden. Yusa had a profound respect and admiration for Kishou, as the idol of all young half bred illegitimate children of the Washuu raised in the Sunlit Garden.
Powers and Abilities Edit
Half-Human Physiology: A half-human hybrid, Yusa possesses enhanced physical abilities that allow him to be a highly-efficient fighter.
Swordsmanship: Yusa is a skilled quinque-user, and a specialist in techniques involving weapons modeled after long swords.
