A boy was born into the Gremory family, but he was different from other devils. The more the years go by, the more his thirst for power and knowledge only increased and he realized that his place was above the others. He won't let anyone get in the way of his ambitions... Every living being will have to prepare for the birth of The Perfect Being ( I don't own Highschool dxd, Kimetsu no Yaiba( Demon slayer) or any reference to any other fiction in this story ) ( My OC is simply Kibutsuji Muzan with certain personality traits and power of several characters from other manga)

After defeating Salem, (Y/N) and his allies thought they finally found peace. But little do they know, they have yet to encounter beings more powerful than any vampire... All credit goes to the original creators. I'm only responsible for the story.

So I was lying around one day and I thought, "hmm wonder what it would be like to do another Jojo crossover." Shortly after I got some ideas and decided to put them to paper as they say. Also I do not own Jojo's bizarre adventure or My hero academia or any of the art used. I've credited the artists names and their work so check them out, cause I can't draw, this is for fan based purposes only. I'd also like to point out that my best friend encouraged me to write this and even comes up with a lot ( well most) of the powers that don't already belong to the My hero characters or Jojo characters. So credit is due to the new types of powers

This is the old version of FoB, with tons of errors and mistakes, along with no foreseeable updates for the future. Please go to the newer, currently updating version here: https://www.wattpad.com/story/328761868-flames-of-betrayal-vale-arc-rwby-x-male-reader
