Ruiga

was the younger brother of Jiga and Renga and the member of the Criminal Brothers.

Background
Ruiga, alongside his brothers, established a coup d'etat, which resulted in the death of the Land of Vegetables' daimyō. After their rise to power, the three brothers betrayed their allies, which included greedy and disloyal courtiers they had recruited, and slaughtered them all. The brothers themselves were distrusting of each other, and plotted to kill off the others in order to have more wealth and power for themselves.

Appearance
Ruiga has cheek length purple hair and yellow eyes, fair skin, thin black eyebrows, wore a dark blue sleeveless T-shirt with light grey circles around the sides, dark blue fingerless arm warmers with light grey circles around the sides, light grey baggy pants, over this is a auburn coloured skirt, dark blue sandals, two light blue teardrops on his cheeks along with a light blue triangular marking under his chin and carries two tonfa's.

Abilities
Ruiga excelled in Water Release. His main technique put him at a tactical advantage. While most ninja normally requires an already existing supply of water to perform any water-based techniques, Ruiga possessed a special technique that allowed him to extract moisture from plant life to act as his source. He could then use that water to perform a number of versatile feats, such as imprisoning and drowning his opponents, or creating protective shields, as his technique would continue to manipulate the water. He could also use the water as a vessel to summon different types of fish, such as piranha and sharks, so they might assist him on land. He was also highly proficient in close-range combat, as evident from how skilfully he wielded his tonfa. He also used his tonfa as dowsing rods, which he could use to find water for his water technique. He was also skilled in dispelling genjutsu.

Peddlers Escort Mission
He was able to defeat Kikunojō by trapping him in a water bubble and summoning piranha to kill him, despite Kikunojō 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 Chōji Akimichi drank all of the available water, rendering Ruiga unable to attack and his shark to be helpless. Chōji then defeated him using Human Boulder, but as Yurinojō was wounded, and Princess Haruna was still in danger, the three left him and continued on their journey. 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, crushing and killing him.
