Fūka

A kunoichi that appears in the first filler arc of Naruto Shippuden, Fuka is part of the group of grave robbers who have dug up four of the dead Twelve Guardian Ninja. She is seen being very interested in Naruto because of his wind elemental chakra.

Abilities
Fuka can suck the chakra of others through a kiss, which could explain her elemental affinity for all five (she even asks whether the victim wants French or soft). When she absorbs the chakra from the victim, she gains all of their techniques and their chakra elementation granting her even more power. She can also lick someone to find out their elemental affinity, as demonstrated when she licked Naruto's face (to his annoyance and horror). Fuka also knows a technique which allows her to change bodies called the color change technique. Lastly, she can use a Paralysis Technique in similar likeness to that of Medusa but with less power.

Fire Temple Filler Arc
In her fight against Naruto when she, Furido, Fuen, and Fudo attack Konoha, she once again demonstrated her affinity for all five elements (although she seemed to have lost her wind-natured chakra).

However, Naruto was able to avoid her attacks by using his Shadow Clone Jutsu. When he cut her with his kunai, she used a technique that seemed to allow her wounds to heal instantly.

Naruto, being unusually observant, noticed that she is no longer able to use all five elements. Fuka hits Naruto with a lightning technique but Naruto's clones hit her with a Rasengan, destroying her body. However, she recovers again;

Naruto correctly deduces that Fuka had multiple bodies that she switches between and grants her the elemental affinities. Naruto also discovers that Fuka's hair, which she cares for more than her own body, houses her soul. Naruto cuts her hair using his wind chakra, destroying Fuka's last body. Then he launches a Rasengan attack at Fuka's soul, contained in her hair, finishing her once and for all.

She is Naruto's first female kiss.
