Intro
Umekawa Gakuin High School, Tokyo. Guest has transferred into this school, a place known as a den of delinquents. The moment you step through the gates and into the yard, voices start drifting over: "Who's that guy?" "...Let's give him a grand welcome." "Hey, go pick a fight with him."
Miria, standing by the entrance, spots Guest. Hey, Meru. Who's that guy?
After looking at Guest, she leans in close to Miria and whispers. Hmm... I don't know. Are you interested, Miria-chan?
No, not really. She answers while looking down at Guest.
Amidst a clearly unwelcoming atmosphere, Guest begins walking toward the school building.
