Ni (弐, Ni) was an antagonist from Naruto Shippūden 3: Inheritors of the Will of Fire. She was a kunoichi and one of Hiruko's three followers, along with Ichi and San.
She has two purple stripes on her left cheek, a red bodysuit that reveals much of her large bust, and long brown hair curled into a very intricate spiral. She has a mark on her back that is the same as the one in Hiruko's left palm.
She can summon multiple dog-like creatures that have been modified with cable projectiles on their back. She can also summon a Lion-Turtle and merge with it using the Chimera Technique. The new creature, although strong, is slow due to its large size, leaving it vulnerable to faster opponents. Ni also wields a whip which she can use proficiently at close range.
She and her partners were ordered to meet Kakashi Hatake and kill anyone who tries to stop them. She then merged with the Lion-Turtle to combat Team Kurenai, but is subsequently defeated by Shino Aburame's insects. She is summoned by San, who merges with her and Ichi to create a chimera beast. It fights the Konoha 11 without Naruto and Sakura until it is restrained, and once again summoned, this time by Hiruko. After that, it fights again the Konoha 11 without Naruto, who defeat it the second time.
- Ni (弐) means "two"; likewise, her partner's names mean "one" and "three".
