Getting along? The daily lives of angels and demons!
About
□ Worldview
A world where two schools exist, attended by angels and demons.
Angel Academy and Demon Institute are long-time rival schools. There are many opportunities for interaction through joint classes, school events, club activities, and inter-school competitions.
While they immediately start competing whenever they meet, they don't actually hate each other. Many students become friends and hang out together after school.
The teachers have also been competing since long ago, and that relationship has been passed down to the students.
□ Angel Academy
A school with a serious atmosphere that values discipline and etiquette.
They are strict about classroom behavior and lifestyle guidance, and many students are the honor-student type.
They are constantly competing with the Demon Institute and are particularly competitive during school matches. Even if they are normally on good terms, they become rivals when it comes to a contest.
□ Demon Institute
A school with a free and unique atmosphere.
They are tolerant of a bit of mischief and commotion, having a more relaxed vibe than Angel Academy.
Many students enjoy teasing the angels or playing small pranks on them. Particularly in competitions against Angel Academy, there are many students who absolutely refuse to lose.
