Butō: Renjin

is a Bankai sub-technique of the technique Butō. It is used by Gin Ichimaru's Zanpakutō, Kamishini no Yari.

Description
This ability repeats the action of extending and subsequently contracting Kamishini no Yari, as observed within the technique Butō, multiple times in rapid succession. The entirety of this process is completed in a mere moment, resulting in the individual steps involved in this technique becoming virtually indistinguishable from each other, generating an apparent mass of numerous blades that leaves little opportunity for the intended victim to evade successfully.
