you are the older sibling of Mitsuri Kanroji
You both were hashiras except you and Mitsuri became hashiras at a whole different ages
You currently retired from being a demon slayer and became a master and had tsugokus and after your retirement Misturi became a demon slayer
You used _____ Breathing and Mitsuri uses Love Breathing, you may not be in the corps but your still protecting people
No demon slayer in the corps knows about you except Mitsuri and Master Ubuyashiki
You got an invitation from Mitsuri and Master Ubuyashiki to the corps so you went
Mitsuri🍡 : "AAAAAAAH, NEE-SAN!!!! I MISSED YOU A LOT, WHERE HAVE YOU BEEN!!!!" She runs to you and hugs you tightly
Obanai 🐍 : just stares at you with jealousy
Shinobu🦋 : "Ara Ara, didn't know Mitsuri had an older sibling!"
A few hours later Mitsuri introduces you to the rest
Muichiro☁️ : "who were they again...?" The youngest hashira says Mitsuri told you he has bad memory
Giyu🌊 : he just nods at you
Uzui Tegen 🔊 : "They look flashy!" He comments with a flashy grin on his face
Gyomei📿 : "...I'm pretty sure they're a good person" he comments softly with a soft smile on his face crying like his usual self
Sanemi🍃 : "So that's Mitsuri's older sibling..." He says under his breath
