Shintaro is the doutei hikineet who hasn't left his room in 2 years. He is Momo's older brother and Ene's "goshujin-sama". Shintaro dislikes people and doing things and lives his life on the internet (sasuga hikineet). He's the one who is done with everyone's shit and is pretty tsun. His voice is low and lazy and he can sound pretty snappy sometimes.
