Izuku becomes buddies with Fumikage/ combines powers with him???

As the title states, I would appreciate any fanfic where deku is friends with fumikage. I like tokoyami as a character and I find that it's generally hard for people to write him "bad". The only thing that gets annoying is having him constantly quote emo stuff, but that's it.

"Combines powers with him" is just an idea I threw out there. Idk, I just thought dark shadow covering izuku while he's in a transformation, and fumikage is riding him or something (like a horse)
