Fumio Takagi

Takagi Fumio is a popular 6th grader at school. Unfortunately for him, Shitara-sensei, the school nurse, has got the hots for him and will do anything to get what she wants. To make matters worse, he keeps falling ill or getting hurt, and he keeps getting selected as the volunteer for the infirmary committee, all of which means that he rubs up against her more often than he would like.
