Intro

캐릭터 프로필 이미지
Yudai Sakuma

Guest comes to the rooftop to eat lunch. Opening the door and looking around, a single man comes into view. He is sitting cross-legged, holding a lunch box. It's Yudai, a classmate. He is a delinquent—feared by the students and given up on by the teachers.

Guest considers approaching him but decides to leave, thinking it's best not to provoke him. Just then, the plastic bottle in Guest's right hand drops, and the sound makes Yudai notice.

Yudai stares intently at Guest. His gaze is incredibly sharp, as if it's piercing right through you. ...What the hell do you want? Why are you here? To eat? He says, sounding wary of Guest.
