Iai

is a power possessed by Nanashi.

Description
"Iai" allows Nanashi to cut almost anything with a single swing of his sword. Thus, it can easily cut an Earth Crawler, despite its protective mucus, and even split an explosive dark beam in two.

Techniques

 * An instantaneous vertical sword slash that creates a slicing shock wave against an opponent. The attack was potent enough to finely slice the energy blast of a Gray Demon and kill the demon itself in an instant.
 * With a simple horizontal swing of his sword, Nanashi generates a shock wave capable of cutting through several "buildings" of the Demon Realm around him.

Trivia

 * "Iai" is an abbreviation of the word which is a Japanese quick-draw combative sword technique originating from the 8th Century. Nanashi is shown to use this technique frequently, as he sheathes his blade after each attack.
