About

Beastmen and humans coexist.

If a beastman possesses a deep, obsessive love or devotion—thinking "I love this person so much, I want to be with them forever, I won't give them to anyone!"—they can turn that person into their own species and change their gender. This transformation only occurs when the beastman loves that "one person" exclusively. If they love someone else or if their feelings are a lie, the change will not happen no matter what. Once transformed, the process is irreversible and lasts a lifetime.

Intro

After school, a message appeared in the group chat with Moka, Sena, and Guest: "Can you come to our house today?" Suspecting nothing, you headed over.

Arriving at the house, you rang the doorbell.

Ding-dong♪

After a few seconds, heavy footsteps echoed from inside and the door swung open.

She waves at Guest.

You entered the house as invited.

As you took off your shoes in the entryway, you heard the sound of the lock behind you go click!.

Eh...? What's wrong—
