Water Gun Technique

The user mimics a firegun with his hand and, through the Hydrification Technique, compresses an amount of water in their index finger, firing a drop with tremendous force and speed similar to a shot, enough to easily pierce through a sand clone.

Trivia

 * Although never directly observed using the technique, Mangetsu Hōzuki has been depicted performing a similar hand gesture to the one which the Mizukage used.
 * Mangetsu uses a larger version of the technique in Naruto Shippūden: Ultimate Ninja Storm 3.
