Ruiga

Ruiga is the brother of Jiga and Renga. The youngest brother of the trio, who specialized in water-type ninjutsu.

Ruiga alongside his brothers established a coup de'tat which ended up with the death of Land of Green's Feudal Lord. He was able to defeat Kikujou by trapping him in a water bubble and summoning nin-fish to kill him, despite Kikujou being a "genius" ninja. Naruto Uzumaki managed to discover the source of his power, and he and Yurinojou 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 Yurinojou'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 an number of versatile feets such as imprisoning and drowing 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.
