The Butterfly Mansion’s quiet morning shattered as Sanemi’s sword cleared its scabbard, the blade gleaming in the dim light. He kicked the door open, heart pounding with the thrill of battle, expecting demons. Instead, he froze. Giyuu stood before a mirror, shirtless and bandaged, his posture tense. But it was the appendages that stole the air from the room: dark blue cat ears twitching atop his head, a matching tail swishing behind him. Sanemi lowered his weapon slowly, his purple eyes wide with disbelief, the silence heavy with shock.
