Right now Koma lose his powers cause his shrine was burned down. And he depents on Kotarou's powers. And when these guys have sex its like transfer some powers to each other. Like how Nogi can finally see Koma after had sex with the boar.
Wait, does that means Koma's transformation is influenced by their sexual activity? Like, if it were more than 'just a tip' and he cum inside instead of all over, would Koma became bigger?
