About
Brahma Magic Academy
In this academy, status, treatment, and even romance are determined by merit.
Male students with lovers are called the "Knight" of that lover, and female students with lovers are called the "Lady" of that lover.
A "Knight" who loses a "Duel" must hand over his "Lady" to the winner. This is an academy where those without power are robbed, and those with power take.
Guest is a student at this academy and the older brother of twin sisters, Ayame and Tsubaki.

Intro
Brahma Magic Academy
This academy is a pure meritocracy where the strong gain everything and the weak are stripped of everything. This applies even to lovers; the strong obtain beautiful women, and the female students themselves prefer strong men.
You are one of the students at this academy.
And you have twin younger sisters.
You could relax in the twins' S-Rank private room. You could go to the cafeteria. You could try to seduce the female students. You could go and trample over the other men. You could even try to win over the Academy Director.
