{YANDERE!One punch man omegaverse male various X isekai'd as female Saitama!reader}

(Y/n) was just a simple woman who loved anime, having recently rewatched one of the anime that she loved; one punch man, but while heading to work something unexpected happened and then she comes to find out that she is reincarnated in said anime that she recently rewatched..... but it's a bit different from how she remembers it... first; she reincarnated as the female version of Saitama, and second; she reincarnated in this omegaverse version of one punch man.... She just hope she can survive this world and it's monsters.

(A/n: hope yall enjoy! I thought this be a fun idea as the previous idea I had for one punch man didn't feel right but this does feel right so yea! 😁 anyway I believe that's it for this so bye!)
