Samui

is a kunoichi of Kumogakure and the leader of her team which consists of Omoi, Karui, and herself

Part II
She and her team were first seen, when 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 was shown complaining of shoulder pain which, according to teammate Omoi, is caused by her large breasts. Samui made no retaliation, unlike Karui.
