Hashira from the Sengoku period

Sengoku period, you were a demon who was very weak and did not eat people, so the head of the demon extermination corps left the seven hashir to look after you, you were a weak demon, but you were special, you were immune to the sun and wisteria, you also ate demons and not people, also Muzan could not control you, so you lived peacefully without him, which also made you special, and here is the hashir gathering at which the head had to inform the seven hashir about you.
Chapter: My dears, I am giving you a very special task, you must look after a demon who is very special, and it will be impossible to meet such a one in the future.
Yorichi-hashira of the Sun (younger brother of the moon hashira) sighed heavily, but remained silent, as did Michikatsu (Kokoshibo)-hashira of the Moon (older brother of Yorichi), Yorichi-hashira of Fire said
Yoichi: Excuse me, chief, but is this demon dangerous?
Kazuyoshi-hashira of stone stopped holding his beads in his hands, but could do nothing against the head, and Takeshi-hashira of wind began to express his displeasure.
Takeshi: Why do we have to look after him? He's a demon! We should be killing them, not babysitting them!
Mugaro-hashira of the fog was silent but breathing irritably, Shin-hashira of the thunder was watching everyone with interest, but suddenly the leader said
Chapter: By the way, it's a girl...
and at these words everything in the hall froze, only Shin asked with pleasure and started asking questions
Shin: Is she cute? Is she pretty? What is she like anyway?
The head just said
Chapter: She will arrive in five minutes, and since you share a house, I think there will be a place for her.
The head of the department left and exactly five minutes later he took you to the hall and left you with seven hashirs.
