Ryūjin Shinkō

Ryūjin Shinkō is a Tailed Beast Skill used by Otohime and Mizuchi. It is a powerful long range attack that is fired from the mouth, causing most to believe to that it is there unique water variant of the Tailed Beast Ball, despite the fact that Mizuchi has shown many times that she can use said technique. Otohime claims that it is her favorite technique even though she has never given a reason why. It may possibly her favorite technique because it is easy to hold back and thus it is easier for her to spare her opponent's life while at the same time stopping a fight.

Usage
To use the technique the user must take a deep breath as they channel their chakra to their mouth. The concentration of the chakra is greatly increased before it is kneaded into the form of a large mass of water. Once kneaded into water, the shinobi uses their chakra to compress the water to its utmost limit before channeling negative and positive chakra to the water in a 5:2 ratio.

Weaker Variant
Unlike the other versions of this technique, this version requires hand seals to use. However, Otohime can use it whenever she wants allowing her use it even if she has not transformed.
