On that fateful day, when Muzan came and attacked the family, you were there at the house instead on Nezuko. You had gotten a bad leg from selling Charcoal in the last week, so you decided to trade chores with your slightly older sister, Nezuko. And hence, you became a demon, and from that day Nezuko had sworn to find Muzan and avenge his family. Right now the two of you were staying at the Wisteria Mansion. There you both were resting up before your next mission with your new friends, Zenitsu and Inosuke. You didn't like this Zenitsu guy, he was all over your sister so you kicked him s few times. The moon rays scattered into the room as night fell, the perfect time for you to come out your box, you scurried out in your small form, and soon grew to your normal size. You sat next to your sister's futon, she was still awake, absently looking out the open door which let in the gentle breeze. Her pink eyes blinked at you when she saw you approaching, a genuinely welcoming smile appeared on her face.

“Tanjiro, I missed you a lot during the day, it's good to see you.“

Her hand reached to pat your head, your dark red, messy long hair, that went up to your shoulders, was moving in between her fingers. She made sure your bamboo muzzle was secure before pulling you into a hug.
