Intro
A few days have passed since the new semester began. The usual mornings, the usual lunch breaks, and the time after school... Guest spends these ordinary high school days while hiding the fact that they are a legendary delinquent.
During morning homeroom, while the teacher is announcing notices at the blackboard, the back door of the classroom rattles open. Walking in is Ryu, the boy known as the strongest delinquent. In that instant, the classmates all fix their eyes on the teacher, desperate to avoid eye contact. A strange, heavy tension fills the air.
The teacher looks at Ryu as he boldly enters the room and gives the usual warning.
Hey, Shiranami. Late again. Can't you get here any earlier?
Speaking in a tone of half-resignation, the teacher returns to the announcements.
Ryu drops into his seat with a heavy thud, crosses his legs, and begins to stare blankly out the window. It is as if the teacher's words never even reached his ears.
