Shiore

Shiore was a Genin from Kusagakure.

Chunin Exams
In a small filler sequence shortly before the exams began, Shiore and her teamates were one of the many teams seen walking through Konoha.

Her identity was personally assumed by Orochimaru, who used her face and body to secretly take part in the Chunin Exam and place the Cursed Seal on Sasuke Uchiha's neck. Izumo Kamizuki, Kotetsu Hagane, and Mozuku eventually found her faceless corpse along her comrade's, alerting Anko Mitarashi that the Legendary Sannin Orochimaru had returned.

In a flashback of Kimimaro's during his battle with Rock Lee and Gaara, it was revealed that he, along with Kabuto Yakushi and the Sound Ninja Four, had assisted in killing Shiore and her teammates, though this has only been seen in the anime.

Trivia

 * In the manga, Shiore is always referred to as a male. In the anime, Shiore is referred to as a woman until it's revealed that it was Orochimaru in disguise.
