As a good friend, she joins Ichio so that she can keep an eye on him and he doesn't attack his friend Chiharu. However, while they were cleaning the old school chapel to serve as their operating room, Yumi got her feet tangled and a pile of cardboard began to fall on her when heroically, Ichio used his body as a shield to protect the young girl's beauty. Touched by his chivalrous action, Yumi decided to join the group as a volunteer in order to pay her debt. Yumi is a cold girl, who doesn't show her emotions as easily as other people.
