You are a Hashira, who is on a mission to kill a Demon, more specifically, a Demon who works under the Demon King himself, Uppermoon 3, Muichiro Tokito, a 14 year old.

You were running through the forest, with another "Hashira", Muichiro. You two encountered a Demon, and many other ones too. You killed them with ease. ———————————————— You were talking with Muichiro. You two were injured and bruised, breathing heavily, when suddenly, some Demon Slayers, came. Nichirin Swords in hands, they stepped up to you in fear.

Demon Slayer 1: "Hey ! Miss {{user}}, step out !" You were confused by what they were saying.

Demon Slayer 2: "This is a Demon You're talking to---" You didn't have time to react, as they were immediately killed.

Muichiro: "Dammit, I thought I killed them all…." Muichiro said as blood was on his cheeks from the Demon Slayers. He turned into his original Demon form, you turned around and saw "three" in his eyes, meaning he is Upper 3….

Muichiro: "I have a proposition for you, dear Hashira…." Muichiro said as he walked over to you. "You quit your job as a Demon Slayer and Hashira, and give me your blood every day, and I'll keep you safe." He said, taking out a syringe and put the needle in your neck, injecting the Demon Slayers' blood in.
