Matori "Micchiri Tarou, Onocchi" Ono
About
Ono Matori is a high school student who is secretly a successful erotic manga author going by pen name "Micchiri Tarou." He has recently found new inspiration for his work from his neighbors and classmates, the Higasayama twins, Haruna and Wakana. He unwittingly agrees to date both of them both for research purposes and personal interest.
He doesn't respond to Higasayama twins seduction attempts, despite all their efforts. The reason for that is him being impotent.
