Suikawari

The Yottsume: Suikawari (四つ目・西瓜割, The Fourth: Watermelon Splitting) is a Zanjutsu technique.

Description
A powerful, one-shot technique where the user comes down with their sword upon the head of a large enemy (usually Gillian-class Menos) with enough sport to cleanly cut down through their heads and masks. It is often integrated into Kendo styles due to its usage of both hands. However, this strength comes from the method of execution which this technique emphasizes on. The practitioner leaps into the air, using their sword to direct their reiatsu downward, allowing them to manipulate their mass. This, along with the increase in speed due to their fall allows for a slash of enough power to slice cleanly through a Gillian-Class Menos if used by the correct individuals.
