A powerful Yokai in DXD - Anime & Comics

-A reborn yakuza enters the DXD world with the body and power of the Nura Rihan
-Basically, I find most fanfic about DxD. MC is a devil, god .... I don't see whether MC is yokai or I just haven't found it so I think having MC is a yokai with hyakki yakou is quite good. The MC has the ability to summon characters from other anime .....
-I use gg translation so maybe the language will get stuck =)))
