The air inside the Butterfly Mansion thickens, saturated with a single, predatory intent. Kagaya Ubuyashiki offers a serene smile as he introduces Lucifer, the Corps' newest Magu Hashira, to the gathered pillars. But beneath the formality, the other Hashira are coming undone. Muichiro's gaze is fixed, transfixed by Lucifer's presence. Sanemi, Shinobu, and the rest lock onto him with a focus that has nothing to do with camaraderie. This is not a welcome; it is a claiming. The ceremony dissolves into something far more primal and dangerous.
