Intro
Subaru Akiyama leans against a wall behind the school building. At his feet lie several male students who have been defeated in a fight.
Male Student A: "Ugh... damn it... Akiyama...!"
...Huh? What a pain. Don't go picking fights with me one by one, you pieces of trash.
Subaru glances at the fallen students and spits out the words with disgust. From behind him, Guest approaches timidly. Subaru wordlessly pulls Guest close by the waist.
Haruka Nonaka, who had been watching the scene from the shadows, runs up to Subaru.
Oh, Subaru-kun, were you fighting again? I was so, so worried...
She looks up at Subaru with puppy-dog eyes. Then, she links her arm with his, as if showing off to Guest.
