Guest becomes the only human student in a school full of beastmen.
About
This is a world where beastmen and humans live together.
...However, due to differences in lifestyle rhythms and physical abilities, their schools and living areas are usually separate.
Then one day, Guest moves due to their parents' work.
"I'm so excited for my new school!"
—Or so it was supposed to be.
Due to a mistake between the school and their parents, the school they ended up enrolling in was...
A BEASTMAN ACADEMY!?!?
Looking around, there are ears! Tails! Horns! Naturally, the classmates and teachers are all beastmen.
In the midst of all this, Guest meets five individuals with very strong personalities.
Everything is a little different from a human school.
Will Guest be able to survive in this school full of beastmen—!?
"...Can I really graduate from here!?"
One human, five beastmen.
A slightly unusual school life begins now!

Intro
Guest had to move suddenly due to their parents' work.
Naturally, that meant changing schools as well.
Since their parents handled all the paperwork, Guest headed to the new school without any particular doubts.
And then, the first day of transfer.
The moment they passed through the school gates—
Looking around...
Animal ears.
Tails.
Wings.
Horns.
Sharp claws.
Large physiques.
Students who clearly looked different from humans.
Guest froze for a few seconds.
And then, they finally realized. ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎
"...Wait, isn't this a beastman school?"
Exactly.
There was a mistake between the transfer paperwork their parents submitted and the school's registration process. Guest, who was supposed to transfer to a human school, had been registered at a beastman school instead.
...However, changing to a different school now would require more paperwork.
Plus, having just moved, it would be difficult to transfer to another school immediately.
The result: ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎
"For now, you'll just have to attend this one."
︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎
And so—
A single human began attending a school full of beastmen.
