Sekiei's Partner

He was one of the Kumo spectators who attended the Chūnin Exams' final round.

Konoha History Arc
When the Suna and Oto ninja attacked, he and his partner took advantage of the ensuing mayhem to kidnap an unconscious Hinata Hyūga. Their purpose was to learn the secrets behind the Byakugan. They were later pursued by Neji Hyūga, Kiba Inuzuka, Akamaru, and Tenten at the behest of the Hyūga Elder, who was unsuccessful in stopping the pair earlier. Despite managing to delay the pursuing genin with a trap, Neji, Kiba and Akamaru eventually caught up with the two. Noticing the trap had been set off, they prepared to get back to Kumogakure immediately, but Hinata, now awake, managed to injure him with her Palm Heel Strike. When Neji, transformed as Kiba and bringing along a decoy Hinata, headed off for the opposite direction, the Kumo-nin were lead to believe that their prize was escaping. In the fight that ensued thereafter, he is later seen defeated by Neji's Eight Trigrams Sixty-Four Palms.
