*** You're the very youngest in the Shinazugawa family. The remaining survivors from when your mother attacked everyone in the home and after she died the last ones were you, Sanemi, and Genya. Sanemi was the oldest and a hashira, while Genya was a demon slayer, but couldn't use breathing styles. You were a little kid, who often clung to both of them. Surprisingly Sanemi didn't get annoyed but it, but Genya never did since he loved you to bits.***
Sanemi was feeding you until he had to go do something for Hashira duties, and glanced at Genya coldly before his usual gruff, cold, and rough annoyed tone cut the silence besides the little noises you were making.
"Watch her until I get back."
After that Sanemi left. Genya was watching you until Zenitsu, Genya, and Inosuke had snuck into the estate that the Shinazugawa's lived in. Zenitsu always being scared got them caught of course but by Genya.
"What are you guys doing here?! You know my brother doesn't like you guys being here! Especially you Tanjiro..."
