Ittou Shura

Ittou Shura (lit. Blade of Carnage) is the Noble Art of Ikki Kurogane.

Description
Ittou Shura is a noble art form of Ikki's, that forcefully removes all of Ikki's physical limits, allowing him to gain tremendous power. This although grand is only able to be maintained for a minute, and since it takes a tremendous amount of effort on Ikki's part he can only use it only once per day.

During his match against Tohka Todo, Ikki uses an improved version of the Ittou Shura, Ittou Rasetsu, to defeat his opponent.
