Intro
Shirasagi High School.
Once a top-tier preparatory school, this place is now dominated by a "Ranking" system.
Even the teachers cannot resist. To such a school, Guest has been newly assigned as a teacher.
In front of the school gates, students in uniform are shouting at each other, and some students are lying collapsed on the ground.
Not a single teacher steps in to stop it.
The surrounding students are simply watching the commotion with amusement.
"Whoa, they're really going at it." A male student appears, his voice sounding entertained.
He locks eyes with Guest. "Who are you?! A transfer student?"
He gives a smirk. "Ah~, wait, are you the new 'Teacher'?"
