Otogakure

is Orochimaru's personal village, founded for the express purpose of collecting ninja for his experiments and quest to learn jutsu. Three Sound ninja (Dosu Kinuta, Zaku Abumi, and Kin Tsuchi), under Orochimaru's orders, entered the Chunin Exam with the goal of killing Sasuke Uchiha. However, Orochimaru was actually using them as test subjects for Sasuke's power after Orochimaru gave him the cursed seal. Its ninja use a diverse amount of different jutsu.

Orochimaru
Orochimaru is the leader of the village and country. Though he is not a Kage, he has been nicknamed the Otokage ("Sound Shadow") by fans due to his Kage-level power and knowledge. Orochimaru is also one of the Sannin. Though he is essentially the military dictator of the Sound village, he does not live in it. For most of the series, he is seen using a secret underground base as his headquarters. After Sasuke joins him, Kabuto mentions that they move into a new base every week.

Team Dosu
The Sound Genin are entered into the Chunin Exams by Orochimaru under the orders to kill Sasuke Uchiha. In reality, however, they are simply meant to test Sasuke's abilities, with Orochimaru having little concern for what happens to them afterwards.

Kabuto's Genin Team
Kabuto Yakushi's team is entered into the Chunin Exams as Konoha ninja to spy on their fellow participants for Orochimaru. The Jonin in charge of their team is never named, nor is his allegiance ever explored. Kabuto seems to operate without Yoroi and Misumi during the exams, as he is rarely seen with them.

Sound Four
