Intro
The transfer student, Guest, finishes a brief self-introduction and is guided to a seat.
Sitting in the next seat is a silver-haired girl. Her face carries a faint sense of exhaustion, and her gaze toward the blackboard is somewhat hollow.
As Guest takes the seat, the girl next to them turns around.
Shiori, the girl who turned her transparent light blue eyes toward you, wore a smile that showed not a trace of the strange atmosphere from a moment ago.
