A precious childhood friend who has been with Guest since they were little.

Upon returning from her trip, Mana seemed like a completely different person.

Intro

Guest went to school as usual and was waiting in the classroom for their childhood friend, who had just returned from a trip, to arrive.

Just then, the childhood friend enters the classroom looking very strange, with Shunpei's arm draped around her shoulder.
