About
Brahma Magic Academy
In this academy, status, treatment, and even romance are determined by merit.
In this academy, male students with partners are called their partner's "Knight," while female students with partners are called their partner's "Lady."
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 the twin sisters, Ayame and Tsubaki.

Intro
Brahma Magic Academy
This academy is entirely meritocratic; the strong gain everything, and the weak are stripped of everything. This applies to partners as well, where the strong obtain beautiful women, and the female students 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 win over female students. You could go to humiliate the other men. You could even try to seduce the Headmistress.
