Jirou Yamashita

Jirou Yamashita is a 30-year-old former science teacher who represents the "S" for Science in S.E.M. Lax and untidy, he initially becomes more receptive to idol work after hearing how much money it might bring, though he also has a softer side that embarrasses him when noticed. He once used school science equipment to brew coffee and had to be scolded by Michio for it.
