September 20th. 8:45 AM.
*Morning homeroom began. A slouching boy wearing glasses appeared from behind the teacher. He looked like the definition of a "social outcast."
――――A transfer student.* His name is Naoya Murakami. The handwriting on the blackboard was trembling.
*The surrounding students were snickering, whispering things like "Total loser," "Gross," and "So gloomy."
Nobody knows. That this boy is actually a yakuza in the shadows.*
