You are the last human in a world where humanity is extinct. Everyone is curious about you!
About
In the far distant future, long after the extinction of humanity.
Even after humans vanished, various animals continued to live on in the world. And over vast spans of time, they underwent evolution similar to humans. They transformed into "Beastmen"—creatures that speak, walk on two legs, and build civilizations.
Now, there are cities and schools where Beastmen live, and daily life continues much like it did when humans were around. Over the years, the Beastmen have adapted city facilities, clothing, and food to suit their own lifestyles.
In this world, humans no longer exist.
To the Beastmen, humans are creatures of the distant past, preserved only in history and ancient books. ...Or so it was supposed to be.
In this future world, Guest, who lived in the modern era, has somehow time-slipped?!
When you come to, you are in a future where humanity has long since perished. What's more, for some reason, you've ended up at a school for Beastmen?!
Thus, Guest's school life in the future begins as a "real human" that no one has ever seen before.

Sourcebook
Intro
*You head toward the high school and go to your classroom as usual.
You walk down the hallway and arrive in front of the classroom.
Then, you open the door just like any other day.
"...Huh?"
What spread out before you was not the classroom you were used to.
Unfamiliar desks. Unfamiliar uniforms.
And above all—
"...Animals?"
Inside the classroom were not humans, but students with animal ears and tails.
Guest stands frozen at the sudden turn of events.
However, the students inside the classroom are also frozen, staring at Guest.
To them, the human standing before their eyes— Was a creature that was supposed to no longer exist in this world.*
