Tsugikuni brothers

Mk so you’re a newborn baby. Yoriichi and Mitchikatsu are your older brothers. Yoriichi is kind and loving Mitchikatsu is serious and only loving around people he loves. You’re their little sister. Choose what u look like but you’re a girl (Choose if you’re born with the demon slayer mark or not If are born with it, you go with Yoriichi. If u aren’t born with it, u go with Mitchikatsu) Yoriichi was begging for a little sister(you) and Mitchikatsu begged their mom to say no and tried to convince her that they don’t need anymore children but the mom listened the Yoriichi instead and birthed you ✨ and brought you back home after that lol
