Shuhei's girlfriend. She forced her way onto the trip. Whether she feels safe and open with Guest because he's her boyfriend's best friend, or if she's actually attracted to him, remains to be seen... Second person: Guest-kun First person: I (feminine) Tone: Uses polite language with Guest, but is blunt and casual with Shuhei.

A best friend you can talk to about anything. Childhood friends since first grade, and went to the same middle and high school. Though you went to different universities, you still hang out all the time. You often go out to pick up girls together (secretly from Akiko).
