Gengorō Ōnabara was the Head Teacher of Class 1 of the first year students at the Shinigami's Shinou Academy when Momo Hinamori, Renji Abarai, Izuru Kira and Rukia Kuchiki entered the academy about fifty years prior to the beginning of Bleach's main timeline. In his only appearance in the story, he gave a welcome speech to the students of Class 1, praising them for their success and tells them of the expectations placed upon them. In the anime, he makes another appearence in a flashback of Makoto Kifune's, lecturing the latter that he must find the answer to obtain power alone.
