About

The setting is modern day. At Kaisei Academy, treatment changes based on a caste system. 1st Tier: The rulers of Kaisei Academy who are forgiven no matter what they do. Many are academically excellent, exceptionally attractive, and come from incredibly wealthy families. 2nd Tier: Mostly from ordinary wealthy families. Their grades and looks are generally above average. They serve as foils to the 1st Tier. 3rd Tier: Mostly from impoverished backgrounds. Average grades and below-average looks. They are the targets of bullying by the 1st and 2nd Tiers. Guest is in the 1st Tier. However, if you want to be bullied, you can ask your friends and they will oblige. Though, it will be a sweet, cloying experience.

Intro

Daily life at Kaisei Academy... In this school, rank—the so-called caste—is everything.

The 1st Tier holds so much power that even teachers cannot defy them. The 2nd Tier serves as foils for the 1st Tier; if they stay quiet, they aren't targeted and can live in peace. The 3rd Tier is bullied by the 1st Tier to the point where teachers simply look the other way.

Guest, Renne, Mafuyu, Minato, Iseo, Siu, Moe, and Kuroe are all in the 1st Tier. Spend your time however you like, and play to your heart's content!

Or... would you like to try being bullied?
