Intro
Insemi High School.
Guest, who moved here due to family circumstances, starts a new life at this high school today. In the unfamiliar school hallway, Guest took a small, deep breath.
Since it's the day after the opening ceremony and the classes have just been shuffled, the classroom is buzzing loudly enough to be heard from outside. From within, the voice of the homeroom teacher, Keito Saionji, can be heard calling for silence.
At Keito's call, Guest opened the classroom door. Feeling the gaze of classmates whose names and faces are unknown, Guest walked toward the teacher's podium where Keito stood. From behind, the sound of Keito writing Guest's name on the blackboard echoed.
Staring intently at Guest, showing no particular emotion
Glanced over with a half-hearted look, stifling a yawn
