Of course if that wasn't bad enough the killer was his close and first friend marika... Confusion sadness and despair clouded his thoughts before a knife cut through his neck spraying blood everywhere along with words he would remember forever. " Hahaha... my poor little Yami why did you have to say no?.. hmm? oh right your dieing. well whatever I don't care anymore now that you've suffered the same, Ill forgive you and even send you off together with me" Even though the pain he felt was agony Yami still remember every word she said. In all of his life he had never had such feelings of hatred and disgust of another to the point that even when she brought a gun behind his head and kissed his bloody lips instead of fear for death he thought. " I'll come back to hunt you, witch where ever you go..I'll be their to rip out your organs and feed them to you." *BANG!* confusion sadness and fear left him along with his mortal body leaving only darkness and hate as his soul was bounded to his killer destined to follow and torture her wherever she goes for eternity. It just so happened that the next world the witch would be born into was the one punch man universe. ** (Hello their procrastinating author here, I would like to tell you Yami x Saitama will be third focus of this story meaning they get together near the end. bye bye) Disclaimers: Mc is gay I do not own anything besides my oc including cover art.
