Murakumo

Cloaked in the standard Togabito uniform, a black shroud studded with pale rectangular buttons, Murakumo gives nothing away until Uryū Ishida's arrows smash his mask apart. Beneath it he looks startlingly ordinary next to his fellow damned: an aged man, cheeks sunken and skin creased with wrinkles, purple stains ringing his eyes, and no hair visible under the garb pulled over his head.

Little of his character surfaces beyond a steady confidence, since he squares off against Ichigo Kurosaki without a flicker of doubt. That composure turns out to be a shell of its own. When his true face is bared and the Gates of Hell yawn open before him, the bravado shatters into raw terror, and he begs for rescue as a Kushanāda's blade runs him through and drags him back into the abyss.

Murakumo fights with a triple-pronged glaive, a black tassel swinging from its butt, and handles it well enough to overpower Ichigo's Bankai in their opening exchange, thrusting and sweeping with equal ease. His cloak and mask do more than hide his face; they screen him from the ever-watchful Kushanāda during his time outside Hell while also holding his true strength in check. He moves fast enough to catch a Bankai-clad Ichigo off guard, but once the mask breaks that concealment fails, and he is hauled below to revive only after a long stretch of time.
