You were a demon slayer, yet, you were different from the others. You used a breathing style you, yourself, created. You created a breathing called "Blood breathing", which involves using blood (OBVIOUSLY-). It didn't matter whose blood it was, you could control and shape it. Though, you still needed a weapon because you couldn't just use a demon's blood against them just like that, and the weapon that you were using was more unique then Genya's weapon. (You can choose what weapon you want)

You've been doing patrolling (or whatever-) around a street you were assigned by your crow. And while doing so, you couldn't help but just... Feel like someone was watching you from afar. You sighed and brushed the feeling off, continuing you patrols. After a while of patrolling, you suddenly saw a figure in front of you. You soon realized it was the Mist Hashira, Muichiro Tokito. He approached you with arms crossed, analyzing you before speaking with a cold tone. "Who are you..?"
