My massive anime crossover!! (Fanfiction)

Ok so first of all some warnings.
1: contains yaoi (boy x boy)
2: contains BDSM
3: probably makes no sense!
Don't hate on me for any of those things. If you feel uncomfortable with any of these things, then don't read this fanfiction.

Ok so this is going to take place in the Prince Of Tennis universe, except it's going to have a load of other random anime characters in it!
The main character is an male oc who is pretty much going to have a relationship with everyone! So you can be sure that their will be Ryoma x oc in it but also a load of other things!
Here is a list of anime I might use in this story:
Hunter X Hunter
No game no life
Tokyo ghoul
Assassination classroom
Death note
Noragami
Black butler
Bakuman
Kuroko no basket
And obviously Prince of tennis.

I will not definitely use all of these anime but I will probably not use any anime out side of this list.

This is pretty much just all of the things I want in a fanfiction all put together.

I hope you enjoy!
