Oggai Squads

Within the CCG, the Oggai form a set of high-tier squads, with at least two divisions known, Squad A and Squad B, and a separate leader placed over each. They were produced from the kakuhou of Rize Kamishiro under the authority of the newly installed bureau director, Kichimura Washuu, who valued a crushing mass of fighters more than a compact circle of specialists.

Kichimura Washuu paired the Oggai with the Suzuya Squad to stand in for the former S3 Squad that Kishou Arima had led, betting on numbers and force over a small band of elites. The squads also carried a hidden second purpose, serving as sacrifices meant for Ken Kaneki. Each member is a child put through experiments in Lab 4 of the CCG Laboratory Division, reworked by way of Akihiro Kanou's perfected kakuhou transplant surgery. Sharing one kakuhou source, every one of them wields a strong rinkaku kagune, and several show a sharpened sense of smell keen enough to hunt down ghouls who had slipped past routine searches. Whether they also gain the rapid regeneration of other Eater-types is not yet known.

Hajime Hazuki led Squad A before his death, and Mayuzumi served as one of its members, alongside numerous unnamed recruits who likewise perished. A supporting group of investigators aided their missions, several of them Quinx produced by Kanou's work on supposedly deceased officers. Tooru Mutsuki acted as a mentor to the squads before defecting, while Okahira worked within that support unit.
