Fū

was a kunoichi from Takigakure and the jinchūriki of Chōmei, the Seven-Tails. Chōmei has been captured and sealed by Akatsuki, causing her death when the beast was extracted. Upon her resurrection, Chōmei appears to have been resealed within Fū.

Personality
Akatsuki member Deidara indicated that Fū possibly despised humanity due to being neglected and hated by her village as a result of her status as a jinchūriki.

However when seen with the other jinchūriki and tailed beast, she appeared to be rather cheerful; smiling as she recalled Son Gokū and Rōshi's final moments before being sealed.

Appearance
Fū wore an orange clip in her short, spiky mint green hair that matched her eye colour, which was also orange. Her ninja outfit consisted of a short sleeveless white midriff shirt with fishnet armour underneath, long white armlets, and fishnet shorts with a short white apron skirt over it, similar to that of Sakura's. Her forehead protector was worn on her arm like Shikamaru's. Fū also carried a cylindrical object in red wrappings on her back, the purpose of it which is not yet revealed.

Abilities
Fū can exhale a sparkling substance from her mouth that shines so brightly that it blinds her enemies, creating an opening for her or her allies to attack.

Jinchūriki Transformations
As Chōmei's jinchūriki, Fū is granted a significant amount of chakra and stamina from the beast. The full extent of her control is unknown, but she could form at least two of the beast's tails upon her resurrection, which Fū used as wings to fly. She has been demonstrated to be very nimble whilst in flight, being capable of outmanoeuvring several of Killer B's attacks using Samehada and his other swords. When she was immobilised by B's clone she changes into her 'Version 2' form and attacks Naruto. She is able to bite her opponents in this mode.

Shinobi World War Arc
In preparation for the Fourth Shinobi World War, Fū is resurrected by Kabuto Yakushi to fight against the Allied Shinobi Forces, before being mobilised alongside the other deceased jinchūriki.

As dawn breaks on the second day, it is revealed that Tobi had turned the revived jinchūriki into his own customised Six Paths of Pain, with each having a Rinnegan and Sharingan in place of their left and right eyes respectively. Each jinchūriki also had their particular tailed beast resealed within them and a chakra receiver embedded into their body. Fū is later seen travelling together with Tobi, in pursuit of Naruto and Killer B. Encountering their targets, the revived jinchūriki are sent into battle. After the enemy evaded Utakata's attack, Fū attempted to obscure their vision with her Hiden: Hiding in Scale Powder Technique, concealing Yugito Nii and Han's ambush. However, when this assault fails, she, like the others, unleashes the power of her respective tailed beast by materialising two of its tails.

Using these tails, which doubled as wings, she confronted B directly. Dodging his initial attacks with Samehada, Fū continued to narrowly evade both of B's swords, despite them being thrown from behind her. This feat was achieved thanks to her sharing the field of vision of the other Six Paths of Pain and Tobi, due to the Rinnegan. Incapacitated in the wake of the Eight-Tails' devastating attack, after B's recent transformation, Fū is then restrained by the latter's sealing technique. However, before the sealing's completion, she manages to escape by adopting her Version 2 form, where she then proceeds to attack Naruto using her Bug Bite technique.

Regrouping with the other revived jinchūriki, after Kakashi Hatake and Might Guy's intervention, Fū charges towards Naruto but is instead intercepted by Guy's powerful blow. Rallying once again, she along with the other jinchūriki prepare to confront the two Konohagakure jōnin, after Han's previous attack is thwarted by Kakashi. After Son Gokū is resealed into the Demonic Statue of the Outer Path, Fū is forced to enter her full Seven-Tails form, as Tobi prepares to go all-out. Unleashing a Tailed Beast Ball along with the others, the jinchūriki instead resort to a direct assault when these attacks are deflected by Naruto, only to then be repelled as the latter adopts his Tailed Beast Mode. In the resulting chaos, Fū is grabbed mid-flight by the Nine-Tails and sent plummeting to the ground, narrowly missing Isopū. With this, the rival beasts regroup and prepare a collaborative Tailed Beast Ball, launching it towards their opponents only to have it met by an opposing one.

As Naruto enters the deeper consciousness of his tailed beast, he meets Fū along with the other jinchūriki and their respective tailed beasts. She recounts Son Gokū and Rōshi's final moments with them with a smile and then later happily introduces herself to Naruto along with her beast.
