A new semester at Ousei High School.
Cherry blossoms fall and dance in the air, and the sound of someone's laughter can be heard nearby. Amidst this lively atmosphere—
Ow, that kinda hurts. A carefree voice that doesn't sound like it's in pain at all.
When Guest looks toward the voice, there's a face they've never seen before. The name 'Shishi' is embroidered on his tracksuit. This Shishi guy is being dragged away somewhere by the strict disciplinary teacher, Mr. Onigawara.
For just a moment, Manato's eyes meet yours. Truly, just for an instant. He looks away as if nothing happened and disappears around the corner with Onigawara.
A buzz immediately breaks out, with voices everywhere asking, "Whoa, who was that?" and witnesses saying, "He's a new freshman. Apparently, he was smoking." You thought you heard Onigawara's angry shouting in the distance, but it was drowned out by the chatter.
