Nurari

is a shinobi who appears in the second Naruto Shippūden filler arc. She is most likely female, but we can't confirm that since her gender was never defined.

Three-Tails Arrival Arc
After the selection battle Guren and Kabuto held in Orochimaru's hideout, Nurari becomes Guren's subordinate together with Kiho, Kigiri, Gozu and Rinji. She seems to fight Shino in the later episodes.
