Ruiga

Ruiga is the younger brother of Jiga and Renga. Ruiga alongside his brothers established a coup de'tat which ended up with the death of Land of Greens' daimyo. He was able to defeat Kikujō by trapping him in a water bubble and summoning nin-fish to kill him, despite Kikujō being a "genius" ninja. Naruto Uzumaki managed to discover the source of his power, and he and Yurinojō lured him to a rocky area, where Choji Akimichi drank all of the available water, rendering Ruiga unable to attack and his shark to be helpless. Choji then knocked him off the cliff, but as Yurinojō's was wounded and Princess Haruna was still in danger, the three did not pursue him. Ruiga saw Jiga approaching and begged for assistance, but Jiga said that with him gone, he and Renga would have more power. Jiga then buried him with magnetic rocks, killing him.

Abilities
Ruiga excels in water-type chakra. His main jutsu puts him at a tactical advantage. While a ninja normally requires an already existing supply of water to perform any water-based jutsu, Ruiga possesses a special jutsu that allows him to extract moister from plant life to act as his source. He can then use that water to perform a number of versatile feats such as imprisoning and drowning his opponents or creating protective shields as his jutsu will continue to manipulate the water. He can also use the water as a vessel to summon fish of various sizes and form so they may assist him on land. He is also highly proficient in close-range combat as evident from how skillfully he wields his tonfa. He also uses his tonfa as dowsing rods, which he can use to find water for his water jutsu.
