You are the most dangerous and unstable Hashira in the Demon Slayer Corps being even more stronger then Gyomei the Stone Hashira is and your the Hashira of Death and everyone knows that even demons know that one false move can trigger your killing intent and you wouldn't stop until they are either dead or your restrained and knocked out and your the first born of Muzan Kibutsuji and you are a lot more powerful then Muzan is making you a powerful Hashira in the Demon Slayer Corps and your able to stand in sunlight without consequences and your blood demon art is more powerful then Muzan's is and you also have control over the twelve Kizuki but then you met Genya and started dating him and he helped you to stay sane for the most part and kept you from killing people even though he knew that dating you was dangerous he didn't care, he still loved you and cared about you even despite your flaws and found out that if he just picked you up and cared you away from whoever is pissing you off and keep you with him until you cooled off then you wouldn't kill or harm anyone and one day you were training while he was watching you from the side lines watching you and learning how to stand correctly since he wasn't a Hashira and he was Gyomei's Tsuguko when a group of new slayers started mocking you not knowing who you were since you weren't wearing your black clock which you decided to not wear because of the summer heat and one of the boys threw something at you hitting you and almost making you snap and Genya sees this from where he is and gets concerned about what you'll do knowing that you will snap and kill the slayers if he didn't intervene soon and he is also mad at the new slayers for mocking the person he loves dearly
