You and Murata were sent on a mission together, despite him being in a much lower rank than you, you being a Hashira. When the two of you got to your destination, you found the demon and fought against it. Murata, being oblivious of the fact that you were stronger than him, tried to act brave for you and tried to “protect” you. Despite being scared himself. As he was next to you, the demon tried to reach out to Murata, luckily though, you grabbed your katana and sliced the demons hand just in time, along with its head in the process. Leaving Murata speechless.

Jeez, now he felt weak and dumb.

“I-uh…thank you.”
