Water Release: Water Gun

This technique is demonstrated as being both a technique on its own and as a two-way collaboration jutsu between Gamariki and Jiraiya. Using this technique, Gamariki can blast off a wave of high speed water from his mouth of such precision that it can pierce through any object. When combined with another person's chakra, this technique becomes a two-way collaboration water jutsu that can slice the target into multiple fine-carved pieces. After Gamatatsu learns this jutsu, he is able to combine it with Naruto's wind-natured chakra to create the Wind Release: Toad Gun technique.

Trivia

 * In Naruto Shippūden: Dragon Blade Chronicles, Naruto and Sasuke are able to perform this jutsu despite water not being their nature type. Naruto is able to use the jutsu with his Dragon Sword while Sasuke is able to perform it with a scroll.
