Samui

is a kunoichi of Kumogakure, and the leader of Team Samui.

Appearance
Samui has short blond hair just around her chin, she wears a revealing skirt with a shirt, and has a body comparable to that of Tsunade, since she has fair skin, blond hair, and very large breasts.

Personality
As opposed to her two talkative teammates, Samui is mature, calm, and generally silent, only speaking when needed.

Senjutsu Training arc
The team was sent to Konoha by the Fourth Raikage to inform them that they would be taking care of Sasuke Uchiha and Akatsuki. In her first appearance, she was shown complaining of shoulder pains which, according to teammate Omoi, were caused by her large breasts. Samui made no retaliation, unlike Karui.

Five Kage Summit arc
After Naruto's fight with Pain, Samui and her team were seen on the Konoha outskirts. After Omoi and Karui had a short argument regarding dating men and women, the team was shocked to find a crater in Konoha's place (caused by Pain's Shinra Tensei shortly before his battle with Naruto). While Omoi believed that Karui had caused it by means of an avalanche after she had hit him with a thrown rock earlier, Samui ordered the team to find someone and ask them what had happened. Later, they came across a Leaf Jōnin, who explained that it was the Akatsuki who had destroyed Konoha. Samui then asked the Jōnin to let her have an audience with the Hokage so that she could deliver the Raikage's letter. She was disappointed to find the Fifth Hokage in a coma, and asked Shizune to talk to the new leader, after which Danzō appeared in front of them and accepted the letter.

Later, she returned to her teammates to find Karui beating up Naruto Uzumaki, to which she told her not to cause trouble. As Naruto requested to see the Raikage, Samui remembered Naruto as the ninja the villagers thought should be the Hokage, but she refused him since the Kage Summit meeting was going on.

As Samui's team left Konoha later on, Yamato implanted a tracker on her to verify her location and follow her. Yamato, Kakashi and Naruto went on to follow Samui, causing them to meet up with the Raikage and his assistants in the Country of Iron, allowing Naruto to ask the Raikage not to kill Sasuke. However, the Raikage refused to heed Naruto's request and Samui and the other Kumo-nin left with him soon after. She is later seen welcoming the Raikage and Killer Bee back to the village.

Trivia

 * "Samui" means "cold" in Japanese, in reference to temperature. It could possibly reflect Samui's personality.
