Zanka no Tachi, Nishi: Zanjitsu Gokui

is a technique of Genryūsai Shigekuni Yamamoto's Bankai, Zanka no Tachi.

Description
Automatically activated upon the release of Zanka no Tachi, this technique is unseen by the eyes of anyone else unless Yamamoto wills it to be seen. It engulfs Yamamoto's body in heat which reaches a temperature upwards of 15,000,000 degrees. Therefore, it becomes impossible to even touch Yamamoto while he is using his Bankai. In this state, Yamamoto's footsteps start melting the very ground beneath him. The passive heat also dries up all moisture for hundreds of miles around; when Yamamoto used this ability against Royd Lloyd, everyone in the Seireitei was affected by the temperature increase in different ways and the overcast clouds hanging over the city instantly evaporated, causing the entire area to become sunny instead. Likewise, when Zanka no Tachi is deactivated, the evaporated water begins precipitating almost instantly due to the sudden loss of heat changing the atmospheric pressure of the surrounding area. The level of heat produced by this technique is so high, it would not actually appear in the form of flames.
