Ennetsu Jigoku

is a technique of Genryūsai Shigekuni Yamamoto's Zanpakutō, Ryūjin Jakka.

Description
Running down the length of the cutting edge of the blade into the ground, a spark of liquid fire branches off in intricate circle pattern formations and creates several immense pillars of flame, which surround the area. The intent of this technique is to trap the opponent in the growing inferno, which develops from the pillars joining one another, and destroy him. This technique is powerful enough to destroy everyone caught in its vicinity, including Yamamoto himself, and can be activated immediately or be set up prior to combat and initiated later at a distance from where it was activated. These flames can incinerate an area much greater than that of Karakura Town.
