About this Novel + Harem
This FF made by google translated + editing by grammar checker. You had been warned that this FF had awful grammar.
Don't take this FF seriously— is Fanfiction after all. Would be mainly combining Campione - DxD - Shinmai Maō no Testament - Fate (maybe) a multiverse, so it would quite different with cannon, maybe—so if you expected to follow the cannon you will be disappointed.
The story focused MC with his human supremacy.
Also there will be ecchi scenes borderline +18, but without lemon scenes.
I'm using Family name + First name
Kai reincarnated to the anime world—just like a curse—being an anime character that has power which means an awful childhood—and a dead parent or just a single parent—saved by an organization called the History Compilation Committee and a girl named Sayanomiya Kaoru.
After finishing a lot of missions from her, Kai gets a mission to oversee Kouh Academy which were two big devil families Sitri and Gremory.
And the journey of Kai rising to the top started as he made his own group power to rival not only Three fanction, but other god and other supernatural being too—
