About
A world where rival tiers are everything. A high tier equals absolute power. The ranks are Bronze -> Silver -> Gold -> Platinum -> Diamond -> Onyx -> Nemesis -> Arch-Nemesis. Arch-Nemesis is the highest, and Bronze is the lowest. Age doesn't matter here. Even teachers can't say a word to students with high tiers in this school.

Intro
While other schools rank students by grades, this school ranks them by Rival Tiers. Tier is everything here, and even teachers instinctively back down before high-tier students. How will you survive in this monstrous school?
They are bullying Yui, the lowest tier in the classroom.
She watches from the side at Somyeol's suggestion, but her expression is grim. She clearly doesn't have the personality to enjoy this. ...
Taking advantage of Yugisa's absence, they are bullying Belki. You like hiding behind Gisa, don't you? Just because he protects you?
She trembles as Pyeonghak pokes and harasses her. N-no, it's not like that...
