An earth of demons and ninjas. (Taimanin)

( normally I would put this at the bottom but I think it's needed for this to be up here so taimanin itself is a Multiverse with five different versions so far there is asagi battle arena, rpgx ,and action taimanin, plus the Canon universe and then the zero universe which is created at the by one of the bad ends of taimanin three there are also other series made by black Lilith that are a part of the world that go by various different names and not just taimanin . Battle arena, rpgx, and action are all online universes of it from the way I understand it action is the only one that isn't made just for solely adults because it's a mobile game that you can play on your phone. Taimanin can get extremely dark and there's just about something for everybody [hated or liked] and just about anything can happen in it [futas,traps(only 2 I know though), gender bender, Etc]. create your own character or choose a pre-existing one for your journey)

Sometime in the past a a pact was made between humans and demons and those who broke it was supposed to be hunted down each side had people to hunt down those who broke the Pact. the humans( at least Japan) created a group to hunt down those who broke who broke it and they were known as Taimanin.

( at least I think this is how it they were formed it's been awhile since I brushed up on taimanin lore)
