Oda was a man described as kind, despite working for the mafia, by Dazai. He had a nice temper, and so, was one of the few persons in the mafia who seldom killed. Nevertheless, when furious, he showed amazing and strong fighting skills that Dazai had warned Akutagawa about. Dazai called him "a man who has no ulterior motive". Oda means what he says, and sometimes mistakenly assumes that about other people—for example, when he gave serious responses to Dazai's joke explanations.
