Otogakure

, called Oto for short, was Orochimaru's personal village, founded for the express purpose of collecting ninja for his experiments and his quest to learn all jutsu.

Three Sound ninja (Dosu Kinuta, Zaku Abumi, and Kin Tsuchi), under Orochimaru's orders, entered the Chūnin 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.
