Ennetsu Jigoku

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

Description
A spark of liquid fire runs down the length of the cutting edge of the blade into the ground. Branching off in intricate circle pattern formations, it creates several immense pillars of flame which surround an 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. The power of this technique is lethal enough to destroy everyone caught in its vicinity, including Yamamoto himself. The power 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 greater than that of Karakura Town.
