Item from Bleach by Tite Kubo
Kisuke Urahara's Zanpakutō — a cane-sword that fires devastating crimson energy attacks in Shikai, with a Bankai that can restructure anything it touches at a molecular level.
Benihime is the Swiss army knife of Zanpakutō, befitting the smartest Shinigami who ever lived. Shikai alone has multiple named techniques: Nake fires energy slashes, Shibari binds with crimson nets, Juzutsunagi links those nets into explosive chains. But the Bankai is where Urahara's genius manifests — Kannonbiraki Benihime Aratame can deconstruct and reconstruct anything it touches, including the wielder's own body. Urahara used it to restructure his own eyes after being blinded by Askin Grimmjow, essentially performing surgery on himself mid-combat. The Bankai's limitation is range — it can only affect what it physically contacts — which is why Urahara kept it hidden for so long, preferring to fight with intelligence rather than reveal his ace. The cane concealment is pure Urahara: the most dangerous man in the room looks like he's carrying a walking stick.
Sealed: a thin blade concealed inside a wooden cane with a curved handle — Urahara's walking stick IS his sword. Shikai: a sleek straight blade with a crimson tassel and u-shaped guard. Fires red energy blasts (Nake, Benihime — 'Sing, Crimson Princess'). Bankai (Kannonbiraki Benihime Aratame): manifests a giant woman who stitches and restructures anything her hands touch.
Also known as: Benihime, Crimson Princess, Kannonbiraki Benihime Aratame
