Ajisai

She was a young woman whose corpse replaced the First Animal Path in Nagato's Six Paths of Pain and was the sole female corpse of the group.

Appearance
The body of the second Animal Path belonged to a young girl, making it Pain's only female body. Like the first Animal Path, it was outfitted with chakra receivers: one above the nose, two on either side of the neck, a row vertically down each cheek, and two studs on each forearm. Its hair is dyed orange and tied together in a sort of onion-like bun at the top of the head, with spikes of hair protruding out of it.

Abilities
As the corpse through which the Animal Path ability was channelled, this body had the ability to summon the animals under the control of Pain such as a snake-tailed chameleon, a crab, a dog, and a bird. Along with these, it could also summon the other Six Paths of Pain corpses and Konan.

Invasion of Pain Arc
This Animal Path is first seen when Pain was getting ready to retrieve the Nine-Tails' jinchūriki Naruto Uzumaki. On the outskirts of the village, the Animal Path is launched through the village's barrier by the Asura Path. As one of the Paths tasked with creating diversions, the Animal Path summons several animals to trample the village. Later mobilising with the Human Path, the Animal Path sets its sights upon the Konohagakure Intelligence Division where it tracks down a chakra receiver.

When Naruto returns to the village, the Animal Path summons the other Six Paths of Pain to the Deva Path's side and then calls forth several summons which are defeated by Gamabunta, Gamaken and Gamahiro. The Path is then subsequently decommissioned by Naruto using his Sage Technique: Spiralling Serial Spheres inside Bunta's mouth.

Trivia

 * Unlike the other paths, the anime did not elaborate on her life before becoming a Path of Pain.
