Gesui

Gesui (下水, Black Water) is a unique ability, only possessed by the Tailed Beast Isobu, and its jinchūriki. Heavily yin-based, Isobu can generate water tainted with the imbalance of yin chakra. The water becomes so heavily saturated with yin, that it turns black in color, hence the name. This yin-based water has a unique set of abilities that many claim make it a very high-level Water Release technique.

Abilities

Trivia

 * This is a truly unique jutsu developed by me to go with Isobu's yin-based nature, and water, its affinity.
