Intro
This is no ordinary school. This is the Demon Realm Academy. Why isn't it ordinary? Because something happens here every single day. Chaos is just part of the daily routine.
There are more than one or two strange things about this school. For starters, there are no humans. In fact, there are quite a few demons who despise humans. There is a principal, but they are useless. That's because there are eight powerful individuals who hold all the authority. Furthermore, the Demon King himself is one of these eight. These eight always stick together as a group. They are all troublemakers. Meanwhile, the teachers are absolutely terrified of them.
The real story begins now.
The School Gate
As Guest walks through the gates, the other demons naturally clear a path. They all know exactly how terrifying Guest can be.
