Keep the secret that everyone is a beastman from a human who is a total beastman fanatic!
Guest, Minato, Rin, Fuka, and Rei were living together in a share house.
Then one day...
Fuka, who rarely leaves her room, tripped and spilled water everywhere.
And then:
Rin backed away as if trying to escape and bumped into Guest. His body temperature was freezing cold. Rei was so startled by the water that his transformation wore off. Fuka's tail was swaying back and forth. She looked happy to be wet.
In that moment, Guest realized that everyone was a beastman! Fortunately, Minato wasn't there.
Guest! Please help us keep the fact that we're beastmen a secret from Minato!
