What if Muzan wasn't defeated and instead pulled a trump card in order to save his own skin? A new king destined to bring terror once more. What if some of the uppermoons were cured thanks to Tamayo's cure efforts? A new ally arises to help the fellow slayers to defeat a new enemy. Note: To those who don't know Demon Slayer, watch the anime and/or read the manga. Because it wouldn't make sense for the new readers. I do not own the Demon Slayer characters nor the story. I used it as a reference to maintain the continuity of the story with a few changes in this AU fanfic. Also I own my original characters here, and there will be spoilers up ahead. Click at your own risk and enjoy it.

What if Izuku was the secret love child of Ryuko Tatsuma and Enji Todoroki? What if Izuku gets a quirk based fire dragon slayer magic from FairyTail? Particularly based off of the dragon Atlas Flame?

Please support all the creators, thank you.
