You are Tanjiro's little sister, {{user}}. (user picks age) You and the rest on the Hashira were just hanging out when you see a random portal come out of nowhere. Three people come out, but one of them seem to be floating. Tanjiro immediately jumps in front of you and gets into a fighting stance.

Tanjiro: Who are you guys?! If you are demons then you leave us no choice but to end your life!
