Ryōdan

The Mittsume: Ryōdan (三つ目・両断, The Third: Bisection) is a Zanjutsu technique.

Description
A variation of the Nadegiri, this technique instead uses a kendo stance along with an overhead strike to send the user's spiritual power outward in a focused line which takes the shape of a crescent wave of energy, effectively allowing them to strike any target in its path with the same power of their strike. It is less precise than Nadegiri but it's range and area of effect are magnified by a hundred times.
