Izuku Midoriya, The Immortal Slayer (Deku x Akaza & Kokushibo)

(Akazakokudeku, bc why not.)

Kokushibo had a lover... but not everyone knew that.
Akaza had a male lover, but he kept it a secret. One day, when the two Uppermoons were talking about their most recent missions from Muzan that they had just completed, Kokushibo mentioned his past lover, a former demon slayer named Izuku Midoriya, which immediately caught Akaza's attention, as Izuku was also his former lover, and was the only thing he actually remembered before he became a demon. Needless to say, this surprised Kokushibo, as Akaza was quite a bit younger than him, and that meant that Izuku was either some sort of demon or something else beyond a mortal human. It was with this that they convicted to find the man they had both once loved, and ask him just how he was still alive, if he was even alive at this time. And that, my friends... is where our story... begins... for this is the heartfelt tale... Of Izuku Midoriya, The Immortal Slayer.
