Ryūgan

was a ninja from Takumi Village.

Personality
Ryūgan is presumed to be the youngest of his group. This, however, didn't put a limit to his prideful and arrogant attitude. Durring his battle with Kankurō and the Konoha shinobi, he boasted about how they were all going to die by his blade. Ryūgan also showed great pride in his weapon, the Garian Sword.

Appearance
Ryūgan is a slender boy, with green eyes that are outlined by blue eye-shadow. His blue hair slightly pops out of his forehead protector, with the rest neatly combed throughout his head. Around his neck is a white scarf that reaches down to his pants. Ryūgan wears a tight, grey shirt that is sleeveless, and that reveals his entire abdomen. On his arms are grey arm warmers with brown straps that secure them onto his arms. His grey baggy pants are fastened onto his body by a thick, brown belt. The lower part of his pants are tucked into his sandals. Ryūgan keeps his sword on his back.

Abilities
Ryūgan is proficient in his use of the Garian Sword, knowing how to manoeuvre it when attacking from short-to-long distances. By channelling his chakra into the blade, the sword itself amplifies it by 10 fold, and unleashes the chakra on the blades in the form of a dragon.

Ryūgan is also able to perform the Ninja Tools Barrier: Reverse Fish Scales Formation in conjunction with his team in order to temporarily incapacitate Gaara.

Ultimate Weapon Arc
He, along with the rest of Four Celestial Symbols Men, abducted Gaara's student, Matsuri, to get access to Gaara. They planned to use the One-Tailed Shukaku inside of him in order to resurrect Seimei so they could seek revenge against the Five Great Shinobi Villages, who they felt did not appreciate their village.

Ryūgan ambushed Gaara and Kankurō which ended with Kankurō challenging him. Ryūgan had the advantage after he obliterated the Black Ant and proceeded to strike Kankurō, but he revealed that it was another of his puppets. After Ryūgan showed he still had the advantage, he again tried to kill Kankurō, but Kiba Inuzuka and Chōji Akimichi arrived in enough time to save him. After they had already messed up several attacks, Ryūgan became impatient, and proceeded to attack them all. However Kiba had already put a plan in action; he and Crow, disguised as Akamaru, would charge Ryūgan and divert him while Akamaru repaired the Black Ant so Kankurō could trap Ryūgan within it. Kankurō succeeded and then used the Black Secret Technique Machine One Shot, impaling Ryūgan several times. Ryūgan's Garian sword was later taken by Hōki.

Trivia
