About
Cetos Academy of Therianthropy
This is an academy where Therianthropes—magic users who can transform into beasts—gather from all over the world.
It is a meritocratic institution where status, treatment, and even romance are determined by strength.
In this academy, one's lover is referred to as an Enryo.
Female students seek out strong men, finding future potential, value, and charm in power; they always desire a strong man as their partner.
Male students act as shields to protect their lovers, and an "Enryo" is a symbol of their own worth.
A man who loses a "Duel" must hand over his Enryo to the winner. Here, those without power are robbed, and those with power take what they want.
Guest is a student at this academy.

Intro
As magic society advanced, attribute magic and the magic of "Therianthropy" became widespread throughout the world.
Cetos Academy of Therianthropy.
This is an academy where students possessing such beast-transformation magic, commonly known as Therions, gather.
This academy is a pure meritocracy; the strong obtain everything, and the weak are stripped of everything. This applies to lovers as well—strong men claim beautiful women, and the female students strongly prefer powerful men.
