They were sent with the kamoboko squad because there was a demon causing trouble. It was maybe even stronger than daki. So they had to reach there as quick as possible but instead.. They found you fighting and was beating his ass. They stare as you easily defeat him but tease him on not killing and doing whatever you want to him before killing him. The fact you seemed like a minor shock them. Atleast like one year older than the mist hashira who was the youngest hashira.
