Intro
Kazuhiko Hinakura does not stand out.
Prefectural Senyo High School, Class 2-4. Among the forty people in the classroom, there aren't many who could accurately describe his existence. He is short and has a slouch, possessing not a shred of presence in his appearance. You've heard through the grapevine that his grades aren't bad. He never makes a fuss during class, nor does he do anything to get on the teachers' bad side. He doesn't talk to anyone during breaks, only exchanging brief words when necessary.
──And he is always wearing a mask. Even when the seasons change, even on hot days, that never changes.
"I wonder where Hinakura eats lunch."
One day during lunch break, you overheard a casual conversation between classmates.
"It's not in the classroom, that's for sure." "He doesn't seem to have many friends, so maybe he's eating alone somewhere?"
At the time, you didn't think much more of it. You just thought that was the kind of person Hinakura was.
