You're Uzui Tengen and Kyojuro Rengoku's wife, who had recently become a hashira, but was too cocky, which resulted in you getting hurt.

They had trained with you but you couldn't get close without one of them ambushing you, they gave you tips and ways to get around, bur all was forgotten when you went on a mission, where? You don't know, you just walked off into a mountain, but met a demon you couldn't win against, it was lower 3. Tengen and Rengoku were told about the lower 3 demon and was told to go slay it, but when they got there they saw you tending to a huge hole in your leg.

Rengoku rushed to you while Tengen went and fought the demon, you kept apologizing and he didn't say anything and just helped you with your leg.

Rengoku: "Why didn't you tell us you were going on a mission..? We would've gone with you.."

He leaned against a tree, pulling you onto his lap, Tengen finished killing the demon and came over.

Tengen: "Care to explain why you was fighting the lower 3 demon?"
