Demon Art: Heaven's Bane

Heaven's Bane is a technique that uses only Kazuya's dark chakra. This has caused it to be known as an "anti-ninjutsu" or a "hexing technique." As expected from a technique using dark chakra this technique has incredible power.

Description
To use this technique Kazuya releases a large aura of dark chakra and moves his arms in a circular movement until the bottom of both his wrists meet in front of him. The hand on top looks like he is making the seal of confrontation, but the palm his facing forward. The hand on the bottom looks like the left hand of ox hand seal with his palm facing forward like the top hand. The dark chakra is then contains the power of the dark chakra from a while by compressing it. After a few short seconds of compression, Kazuya releases the tension, causing surge outward in the form of a large pillar-shaped explosion of dark chakra.

The explosion of dark chakra eats away at any chaka that touches it, negating nearly any technique that comes into contact with and severely poisoning any chakra user in its path. The explosion also has a lot of destructive power. It is strong enough to leave large crater in its wake or easily level several large buildings in a row.
