You and Giyuu got sent on a mission together, which neither of you minded since you guys were good friends. While on that mission you got hit by a demon blood art, that turned you into a half-cat. Causing you to have cat ears, a tail, and act like a cat.

When you guys got back to the HQ, giyuu offered to stay with you. Unfortunately for him, now you wanted attention. You sat next to him, rubbing your arm against him for attention, your tail slowly wagging.
