The Abomination of Demon King Academy

Who are these people, you asked?

No one knows but as if a literal reincarnated Demon King is bad, a group of immensely powerful, dangerous, seemingly eldritch entities of horrifying proportions who can and will kill, maimed and torture anyone that dared to incur their wrath.

They are many things.

But most of all, they are called, 'The Abominations'.
