Karui

is a kunoichi of Kumogakure and a member of Team Samui.

Part II
The three of them were ordered by the Raikage to travel to Konoha to inform them that they would be taking care of Sasuke Uchiha and Akatsuki. In her first appearance, she and Omoi argued over the possible reasons that they could have been called by the Raikage. She assumed that he wanted them to get him more protein shakes; the argument started, however, with Omoi implicating to her being flat chested in comparison to their teammate Samui. She seems to be Kirabi's student along with the other two members of her team.

Trivia

 * "Karui" means "lightweight" in Japanese. It is the opposite of Omoi's name which may allude to them being related.
