Fuu (フウ, Fū) was a kunoichi from Takigakure and the jinchūriki of the Seven-Tails.

  At some point, Fuu became the jinchūriki of the Seven-Tails, Chōmei. In the manga, at some unspecified time either before Gaara‘s capture by Deidara, or some time in between Gaara’s capture and the capture of Yugito Nii by Kakuzu and Hidan, Fuu was captured by the Akatsuki, as after Yugito was sealed, according to Pain only three tailed beasts remained uncaptured, and she thusly died from having the Seven-Tails extracted from her body. In the anime, growing up in Takigakure as the village’s jinchūriki, the village leader Shibuki took great care in keeping Fū protected. He also taught Fuu the importance of friendship and loyalty.

  While seen with the other jinchūriki and tailed beasts, she appeared to be rather cheerful with a happy-go-lucky and somewhat carefree disposition; smiling as she recalled Son Gokū and Rōshi‘s final moments before being sealed. She also uses ‘ssu’ (っす) at the end of her sentences — which is more commonly used by boys, giving her somewhat of a tomboyish demeanour. In the anime, Fū is shown to be somewhat of a troublemaker, as seen when she was summoned by Shibuki, she thought she would be scolded for something that she did. Fū also appears to be easily bored. She is also noted to be somewhat like Naruto Uzumaki, being a loud-mouth and reckless in her actions. Also, unlike most jinchūriki, Fū is shown to be very friendly and eager to make friends. Despite coming to the Chūnin Exams where all were expected to compete against each other, Fū still wanted to play games with the others. Part of this desire stems from listening to Shibuki’s teachings and wanting to help promote peace. In her love of having fun, Fū is also shown to be fearless, jumping into a sandstorm at night to fight a mysterious danger, seeing it only as exciting.
