Omi is breaking in the new nurse, Iku. Not only will she have to teach her hospital duties, she will also have to teach her how to deal with notorious patients. Like Hiro in Room 4, hes quite a handful. The only way he will cooperate is if he gets to eat shit, literally. So Omi takes Iku to the room and introduces her to Hiro, who is hungry for shit. She shows the horrified Iku how to squat on top of Yamadas face and shit right into his open mouth! Having no choice but to follow the older nurse, she does the Hiroe and produces shit for Yamada to eat!
