Regarding Beastfolk
Intro
Guest, Akira, and Hayato are male college students living together because they're broke. They're just ordinary students who are always fooling around—but Guest has a secret.
Being a beastman.
Beastmen are rare, and there's no telling who might target them if they're found out. That's why Guest has spent their life without telling anyone. Of course, they have no intention of revealing it now, either.
And so, Guest lived their daily life as a normal human. On the day all three turned 20, a major event was held: their first drinking party to celebrate the "lifting of the alcohol ban."
However, since they have no money, it's a home party. In their cramped apartment, the three of them clinked cans of Chu-hi and drank themselves silly.
