Tayuya (多由也) is a kunoichi of Orochimaru's Sound Four. Personality Tayuya is foul-mouthed towards most people, especially Jirobo, calling him "fatty", as he criticized her over it. She didn't think much of Shikamaru Nara as a leader, but as a weak, useless rat, who ran away when she used her Doki to attack him. Of the Sound Four, Tayuya was the only member to show a sense of morality, as she berated Shikamaru for sacrificing his teammates to bring back one person who voluntarily left. Involvement in Plot Invasion of Konoha arc: Tayuya made her first appearance with the rest of the Sound Four, erecting a barrier to keep others from interfering in Orochimaru's fight with the Third Hokage. She later escorted Orochimaru when he fled. Sasuke Retrieval arc: The Sound Four escorted Sasuke Uchiha when he decided to join sides with Orochimaru. When Team Shikamaru caught up with the Sound Four, they managed to take the barrel Sasuke was being carried in from her. While trying to take it back, she was confronted by Kimimaro, who threatened to kill her if she didn't deal with some of the Konoha ninja. She fought Shikamaru, but was repeatedly outmatched by his superior intellect. When she started relying on brute strength, she was almost able to kill him, but Temari arrived, and killed her first. Fourth Shinobi World War: Confrontation In the anime, Tayuya was reincarnated by Kabuto Yakushi along with her Sound Four teammates during the Fourth Shinobi World War. She was able to fight against Shikamaru again. Despite losing even when her body was enhanced by her summoner, Tayuya quickly reconstructed herself and cast the Space–Time Technique Formula: Underworld Turnover to teleport herself and Shikamaru to another location where her comrades have brought their opponents to. They continue their battles with their enemies, switching opponents while Shikamaru comes up with an analysis. Tayuya reveals that even their defeats will not release the barrier. The Sound Four overwhelm the Konoha shinobi with the hatred they hold for them. Taking advantage of this, Shikamaru continues to bait their hate to lure Naruto to the barrier and break them free. Tayuya and her comrades decide to fight against Naruto, but were defeated before their souls return to the afterlife.
Kimimaro was the fifth member of the Sound Four, thus temporarily changing their group name to the Sound Five. The original four were forced to accept him against their will, as Kimimaro's combat abilities exceeded all of their skills combined. He was the sole survivor of the Kaguya clan, who could manipulate their bodies' skeletal frame. The Kaguya clan was wiped out when they attacked Kirigakure, seemingly for no reason other than the desire to kill. Having underestimated their opponent's defenses, they were slaughtered to the last man, with only Kimimaro surviving. NOTE: Though some fans believe that his full name was Kimimaro Kaguya, the second databook only said his name as Kimimaro. Kimimaro was referred to by Orochimaru as the most powerful member of the clan, having "abilities that even that war-loving clan feared". Because of this, he was locked away in a cage for most of his life, only released occasionally when needed to fight other clans. Like many of Orochimaru's closest followers, Kimimaro was branded with a cursed seal, which gives him greater power at the expense of his free will. When in his level 2 form, his appearance is similar to that of a dinosaur, with dark gray skin, six large bone spines on the back of his chest, and a long bone spiked tail. He also possesses a great deal of control over his cursed seal, as he is able to control its spread throughout his body without fully activating it. Kimimaro was apparently friends with Jugo at one point, and his control over his cursed seal impressed the latter. Karin claims that Kimimaro was the only one who could stop Jugo without getting hurt. Kimimaro succumbed to his disease and died in the middle of his fight with Gaara during the Sasuke Retrieval Arc, moments before he was about to deliver the finishing blow to Gaara and Lee.

Matsuri is one of the first students of the Sunagakure ninja school modeled after the one in Konoha. She chooses Gaara as her teacher, despite his lingering status as the village's weapon. When it comes time to begin training her with a weapon, Gaara suggests she uses a jouhyou, it being the safest of all the available options. She is initially fearful of weapons after the murders of her parents, yet becomes accustomed to them after realizing they can be used to help others. She is the first of the anime's filler characters to make an appearance in Naruto: Shippuden, where she joins a Sunagakure rescue team meant to rescue Gaara after his capture. She becomes somewhat outspoken over the timeskip, as she complains when her team spends its time protecting Sunagakure's borders rather than trying to save Gaara. She later appears during Gaara's revival, praising him and boasting about his powers.
