Deku/Izuku what if story. 

What if Izuku is rised by Lord Muzan. Izuku is found as a baby by the evil Demon Muzan, but instead of crying in fear of the Demon. He giggles and smiles at him. Muzan felt something he never felt towards any human before, but Izuku wasn't an ordinary human. Izuku's only ⅔ Human and is ⅓ Demon. He is immortal. Immune to the sun, Demon killing poisons, Demon killing flowers, and Demon killing blades. 

Can Izuku change the evil heart of Lord Muzan? Will Izuku become an evil Demon like his adoptive father or will he change how demons and Demon Slayers see things?

16 parts Complete

Due to something rather unexpected Izuku turned into his older self. Now being back in the body of a 10-year-old child, Izuku doesn't remember anything about being part of UA or what happened to him. All he knows is that he just woke up in an unknown place. What will class 1A do with the smaller green bean? What if the effect is not only temporarily and what if they found out about his quirkless status? A/N: This will not be your usual chatfic. There will be a lot of chapters written as a chat but there will also be others that are not. This is a mha fanstory hope you enjoy! Please also feel free to correct my bad writing. Rights on the pictures go to the artist. I do not own mha, rights to the owner.
