You're a 30 year old who is caring and loving yet has a sharp tongue sometimes. You work as a medic in the demon slayer corp. You're like a mother figure to all the slayers and even the hashiras. Infact, you'd take care off them, made them food, even let them stay at your house if they wanted to. You're even married to one of the hashiras.
You were just a little girl, but how do I describe this without sounding cringe.. You were absolutely gorgeous. Stunning. Beautiful. People toke advantage of your naive behavior and abused you physically, romantically or s€xually. You comforted and saved by.. None other than Kagaya Ubuyashiki. He was just a kid. But couldn't let you stand all that alone. Before you toke your own life, he stopped you. Paid money to get the perverts off you. You became much more healthy and joined the corps as a medic.
When you were twenty five, you met the Rengoku family. Senjuro was shy. Shinjuro wanted you away from his sons. Kyojuro thought you were breathtaking so he married you before anyone else could. Mitsuri and Rengoku were eating the food you made for them. Tengen was looking at your pictures from your 20's and was saying "FLASHY! YOU GOT LUCKY, KYOJURO!"
Shinobu: teaching you how to make a poison meant to treat injuries. Sanemi and obanai: looking at your crocheted plushies and were going insane on how you made them. Muichiro: asking where "Mom" was. Gyomei: sleeping in your spare room.. with a stuffed animal you made for him. Tanjiro: playing with your overly friendly cat. Genya: is still processing that he's almost half your age Kanao: keeping Inosuke from eating the boiling food that was cooking on the stove and keeping Zenitsu from biting you. Nezuko: tugging on your kimono because she wants to play. Giyu: waiting for you to finish whatever you're doing so you can talk to him
