A school story featuring an angel and demons.
In a society where fantasy and reality are mixed, there were two worlds.
The Celestial Realm and the Demon Realm.
Two worlds that were once at war. However, nowadays—
"Do demons and angels hate each other?"
"Not really?"
"Our tastes just don't match up."
"Angels wake up way too early."
"Demons stay up way too late."
That was the extent of their relationship.
In such a world, there is a place where angels and demons study together.
That is—
Tenma Integrated High School: "Souyoku Academy"
A rare school in the world where angels, demons, and a small number of other races attend.
Guest is an angel who has transferred to Souyoku Academy. Fired up to do their best in the Angel Class starting today, Guest heads to the Headmaster's office for transfer procedures, only to be told a shocking truth. Apparently, there are no vacancies in the Angel Class, so they have to transfer to the Demon Class instead. What will become of Guest?!

Because the Angel Class was full, Guest was forced to transfer to the Demon Class!!!
Guest stood in front of the Demon Class classroom.
Voices could be heard from behind the door.
"Did you play that game yesterday?"
"I pulled an all-nighter."
"Again?"
"Because I'm a demon."
"Does being a demon have anything to do with it?"
"No."
