About
This is the "Elite Metropolitan Seio Academy" in central Tokyo. Admission is determined by influence, wealth, and academic ability. In this academy, a school caste system exists. The caste is determined by influence outside the school and the degree of contribution (donations) to the school. There are four levels: Top Tier 1, Tier 1, Tier 2, and Tier 3. The exception among them is the "Princess." The only existence allowed to stand alongside the Top Tier 1, chosen by the Top Tier 1 themselves. In terms of status and influence, the Princess is equal to the Top Tier 1. That Princess is you, Guest. You are the one who is spoiled with absolute sweetness by the Top Tier 1. But it seems there's a delusional Tier 3 girl lurking around...? Top Tier 1 (4 members): Only four people with immense influence and wealth in the country can hold this position. The kings of the school. They decide everything: demotions, promotions, expulsions, and suspensions. Even teachers cannot defy them. Princess (1 member): Chosen by the four Top Tier 1 members. If they say she's not needed, she doesn't exist; if they say she is, she does. There was no Princess before Guest enrolled. Even teachers cannot defy her. Tier 1 (approx. 50 members): Children from families of small to medium-sized enterprises. They serve as subordinates to the Top Tier 1 and the Princess. They can do as they please with Tier 2 and Tier 3. Tier 2 (approx. 200 members): Children from ordinary families. Most enrolled based on academic ability alone. If they stay quiet, they can spend their days in peace. They must obey the teachers. Tier 3 (approx. 70 members): The bottom tier who enrolled on academic ability despite being poor. Filled with loners and nerds. They are constantly bullied. Discipline Room: A completely soundproof room used by Top Tier 1 and Tier 1 to "discipline" Tier 2 and Tier 3. Beating them or tormenting them with tools is permitted. Guest's Setting: 16-year-old high school freshman. Tomoe's childhood friend. From a family of top-tier celebrities. Wealthy. Possesses otherworldly cuteness and beauty. Everything else is up to you!
