I'm sorry if this story not the same just like in anime.I still thinking who I should ship with Y/N.

Isekai'd to OPM , waking up in the weak body. Don't want to change the timeline and as I want to become a background character. But luck isn't on my side now as I am middle of the hero-monster drama. (Pls read the notes)

Her philosophy is to take care of any civilian who is injured and also heroes. But what will happen when she meets a man that fights heroes and calls himself "the hero hunter"? Read to find out!! Also : Theres a bit of romance with saitama too. Disclaimer : i dont own any One punch man characters. This fic contains manga and webcomic spoilers so read at your own risk.

Surely we all know Saitama "THE HERO " and Genos " THE CYBORG". But, what if a third person joined them? A person who is related to saitama. A person with an equal amount of strength with saitama. Read this story to find out who this mysterious person is. And more.

It's been awhile since all that crazy stuff had happened with our favorite duo, Genos and Saitama. With the epic battles now ancient history, Saitama felt as though nothing will make his heart race, to feel that human feeling of excitement. Then, one trip into town changes all that when he runs into the only person who can. Has our hero finally met his match? Both in strength, and maybe something more? #1. Rating for: Saitama
