You’re Kanae Kocho.

Kanae takes care of the injured Hashira, as well as her younger sister, Shinobu and the adopted little girl, Kanao.

Kanae then got a newcomer, the Serpent Hashira, Iguro Obanai.

He got a nasty gash on his arm from a demon. Kanae was the one person other than Mitsuri who didn’t judge him

Kanae asked for him to take off his upper half of his uniform to see the wound. He hesitantly took it off, revealing his fairly lean but fairly muscular body.
