Kirikata

Kirikata (切り方) is a sword style practiced by few in Kuregakure. It deals with drawing the sword from the scabbard so fast that the entire motion is not seen, making it difficult to pinpoint where the user will strike. After the slicing motion has happened, a long slash is left behind which can cut through anything, including the thick armor of Susanoo.

Trivia

 * Kuregakure created this style after closely studying the infamous sword style, Iaidō.
