Eriko Takahashi

The happy-go-lucky main character of the story, Eriko gets good grades but is nevertheless quite clumsy and not at all athletically coordinated (unless it is to escape the many perverts who often cross her path). She tends to be the main victim of the perverted actions (accidental or not) of Odagiri, though she occasionally uses this to blackmail him. Described a few times as "A nosy busybody", Eriko tends to go out of her way to find out people's problems. She's also quite fickle. Eriko is frightened of injections.
