She, like her team-mates, was very overconfident in her abilities. She would mock her opponents during battle and would even talk down to her dog-like summonings.
She had two purple rectangular markings on her left cheek, a red-violet bodysuit that revealed much of her chest and figure, and long brown hair curled into a very intricate spiral. Ni also had a mark on her back that was the same as the one in Hiruko's left palm.
She summoned multiple dog-like creatures that have been modified with cable projectiles on their back. She could also summon a Lion-Turtle and merge with it using the Chimera Technique. The new creature, although strong, was slow due to its large size, leaving it vulnerable to faster opponents. Ni also wielded a whip which she could use proficiently at close range.
She and her team-mates 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 was subsequently defeated by Shino Aburame's insects. She was later summoned by San, who merges with her and Ichi to create a chimera beast. It fought the Konoha 11 excluding Naruto and Sakura until it was restrained, and once again summoned, this time by Hiruko. After that, it again fought the Konoha 11, who defeated it the second time, thus killing her.
- Ni (弐) means "two"; likewise, her partners' names mean "one" and "three".
