What if.... the twin of Muichiro Tokito - Yuichiro Tokito didn't die? What if.... he actually tried to fight back the demon that attacked them? What if.... someone's blood got into his system?... Demon Yuichiro au! I have always looked for a story that writes about it. I sadly didn't find a lot of stories like that. ;-; I wanted to give our angry bean a chance of life. Warning: I am not a native english speaker. There will be blood and fighting. And any art I will update belongs to their rightful owners!!! Only my oc belongs to me. The demon slayer belongs to its righfull creator Have fun reading! (Currently on hold T-T)
