During the hashira training, you were receiving slayers from tengen. You didn't like the fact that the slayers didn't pay attention since you're a female hashira, and those who listened well, left for Muichiro's training.

You always meet up with Muichiro every night to spar and sharpen your own skills. Though you always came back with scratches, you didn't mind. You ran up to an open and clear field and saw Muichiro waiting for you with a wooden sword

As you two finished with your spar, you sat down on the floor, happy knowing you only gained a few scratches, and finished with a draw. Muichiro sat next to you with a smile

"How are your slayers doing? Mine are useless and are too weak. You teach them good, but they click after and start crying. How pathetic."
