Water Blade

Water Blade (水刃) is an Art and Common Skill used by Rimuru Tempest.

Abilities
It can shoot out a thin water blade with tremendous cutting power.

Description
Following the principles behind Hydraulic Propulsion and Water Current Control, Rimuru trained with the idea of "cutting water". After a week of practice, he had increased the pressure of his Hydraulic Propulsion's water gun enough to cut through a boulder, acquiring the skill. Water Blade, Water Current Control, and Hydraulic Propulsion then evolved into the Extra Skill Water Manipulation.
