Jirou is a 30 year old ex-science teacher. He represents the "S" for Science in S.E.M. He resigned after hearing about Michio Hazama’s dream to become an idol. While he was hesitant on leaving, he perked up to the idea once it was mentioned how much money they could possibly make. Jirou is very lax and kind of a slob.

He often uses the school’s science equipment to brew his coffee, which Michio has to scold him for. When him, Rui, and Michio first began auditioning for becoming idols and failed many times, he was going to give up until Michio admitted to him that he felt bad for dragging him and Rui Maita into his own dream of becoming an idol. Jirou comments that even if they had stayed teachers, they wouldn’t be living that extravagantly.

Despite his appearance and claims that he only cares about getting rich, he does have a few soft spots. He usually gets bashful once someone notices. He is shown to be quite bad with handling his appearance, but Michio comments that when he cleans up and stands up straight, he looks quite dashing.
