Shunkō

is an advanced secret battle technique, combining the physical techniques of Hakuda with the spell-based techniques of Kidō.

Description
It is an ultra-powerful technique in which one drives Kidō into one's arms and legs. The Kidō itself can also be controlled and fired at opponents from the body. Shunkō first appeared being used by Captain Suì-Fēng in her fight against her old master, Yoruichi Shihōin. Suì-Fēng states she invented the technique of combining Kidō and Hakuda so recently that she had no experience with it in battle, let alone enough time to give it a name. Yoruichi, however, reveals Shunkō is the technique's name, and that she invented and learned the ability long before Suì-Fēng. The keisen uniform has no back or sleeves because the fabric will rip apart when the user's back and arms are filled with Kidō. Though Yoruichi's Shunkō is perfected, unlike Suì-Fēng's version, she still has difficulties controlling it. It could be said that Shunkō is a secret technique used by the Corps Commander of the Executive Militia. The uniform worn when punishment is carried out is specifically geared for Shunkō.
