NaruFuu

NaruFuu is a Het ship between Naruto Uzumaki and Fū in the Naruto series.

Canon
Both Naruto and Fū are Jinchuriki and were compared to each other long before they even met. Fū was taking the Chunin Exam while Naruto was off training with Jiraiya far away. She cared more about making friends than anything else and risked herself to save Gaara when someone was attempting to extract the Shukaku from him. After they were saved, Gaara mentioned that Fū reminds him of Naruto. Fū was later killed after the Chunin Exams.

Naruto and Fū finally met on the battlefield during the Fourth Shinobi World War after she had been resurrected from the dead. At first, she was traveling along with Tobi in pursuit of him but he removed her Chakra receiver which allowed her to regain control of herself. Fū then introduced herself and her tailed beast Chōmei to Naruto. After the battle was over, Fū was able to return to the afterlife.

Fanon
NaruFuu has a small amount of popularity in the Naruto fandom. It is mostly considered to be a crack ship due to the limited amount of interaction between Naruto and Fū. The popularity for this ship somewhat grew when more of Fū was shown during filler episodes and her personality while she was still alive was shown. Many fans feel that they are similar and would be good together. However, the fact that Fū is dead makes a future relationship between the two impossible.
