Renga

Renga is the brother of Jiga and Ruiga. He is also the mastermind of the coup de'tat in the Land of Vegetables which resulted in the death of its daimyo.

Abilities
Like his brothers, Renga has a very unique special jutsu presumably only he can use. In a manner similar to Haku's special clan ability, Renga has the ability to create ice. By focusing his chakra to condense moisture particles in the air, he can form thin and transparent disks of ice. These disks have several uses. They can be hurled with tremendous blunt force at a target, which will be hard to dodge because of their transparency. They can also be strung together to spy on areas both far and hidden from a distance. They also have a defensive purpose of creating highly durable shields or disks to stand on to "float." By forming the ice into a large lens, he can hover in the sky to focus the rays of the sun, which can focus into a powerful beam capable of melting and exploding the pinpointed area.

Vegetable Country arc
Of all the brothers, he had the most twisted worldview, and believed most strongly in using people for his own ends. Following the death of Ruiga and Jiga, Renga attacked Naruto Uzumaki and Haruna.

He wondered why Naruto would risk so much to protect Haruna, and why Haruna would stand between him and Naruto. After using his special jutsu so many times, Naruto managed come up with a way to counter it and reflect it off his forehead protector, and wounded him so badly that he was unable to continue fighting. Haruna was about to kill him to avenge her father, but was unable to go through with it. What happened to Renga after that remains unknown.
