Alright I really been thinking about this for a loooonnnggggg time and well, I have 2/3 ideas for it. First off there both Xreader books buuuutt they take a different turn.

Minato: Alright the first idea is the reader is half human, half angle, and half demon, which will be explained if well voted.

Ruby: The next one will be a little different from other stories. The reader will either be the young brother Issei who's been gone for a long time and spoiler he's actually his cousin. Or little same idea but he's not related to family but is like a little brother and lives with them.

Minako: Also the reader will not become a devil but will have a relationship with the members.

Slayer: Well that's all for today and now I need to get back to my RWBY book. I'm being a little lazy and neglecting it a little by playing games on my Xbox One.
