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 and seniority mean nothing here. Even the teachers cannot 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. Tiers are everything here, and even teachers instinctively back down before high tiers. 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. It seems she isn't the type to enjoy this sort of thing. ...
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 bullies her. N-no, it's not like that...
