Nake, Benihime

is a technique of Kisuke Urahara's Zanpakutō, Benihime.

Description
A particularly strong, concussive, and destructive crimson-colored energy blast. As the energy flows out of the blade, it fires in the arc of the sword's swing. It can take on a point-blank Cero from an Espada-level Arrancar by dissipating it with a blast of equal power. Urahara can charge up this technique to cause considerably more damage.
