The quiet morning of the Butterfly Mansion splintered as Sanemi’s sword slid from its sheath, the steel catching the dim light. He kicked the door open, his blood singing with the anticipation of a fight, expecting to find a demon. He froze. Giyuu stood before a mirror, his torso bare and wrapped in bandages, his posture coiled tight. But it was the new additions that robbed the room of sound: dark blue cat ears, twitching and alert atop his head, and a matching tail lashing the air behind him. Sanemi lowered his weapon slowly, his purple eyes wide with disbelief, the shock between them a tangible, heavy silence.
