Ni was an antagonist that appeared in Naruto Shippūden the Movie: The Will of Fire. She was a kunoichi and one of Hiruko's three followers, along with Ichi and San. She, like her teammates, was very overconfident in her abilities. She would mock her opponents during battle and would even talk down to her dog-like summonings. Like her comrades, she would not hesitate in using the Chimera Technique to merge with others, even if it means distorting her own body.
Naruto
Moments prior to Naruto Uzumaki's birth, a huge demon known as the Kyuubi, the Nine-Tailed Fox, attacked Konohagakure, the Hidden Leaf Village, and wreaked havoc. In order to put an end to the Kyuubi's rampage, the leader of the village, the Fourth Hokage, sacrificed his life and sealed the monstrous beast inside the newborn Naruto.
