Nonō Yakushi

, renowned as, was an ANBU from Konohagakure and a former member of the ANBU faction: Root. Some time after leaving Root, she became a captain of the Konoha Medic Corps where she served mainly as a caretaker of orphans at an orphanage outside the village where she was called. While undercover in Iwagakure, she went by the name.

Background
Nonō was a member of Konoha's ANBU sub-division Root. She was an expert in the area of intelligence gathering, but left the organisation to run a small orphanage instead.

While out one day, she found a wounded child near a deserted village. She healed the young man and brought him back with her to the orphanage. As the child could not remember anything, at Urushi's behest, she named the child Kabuto for the helmet he was wearing at the time. One night when he was caught out of bed past curfew, the other caretakers brought him to the clock in order to teach him time. Noticing that he was squinting, she took off her own glasses and gave them to him. This caused the young Kabuto to break down crying, thanking her for everything as she comforted him.

Three years after taking Kabuto in, the orphanage was treating wounded Konoha shinobi, with Orochimaru taking an interest in Kabuto. Root leader Danzō Shimura with two Root guards (one being Orochimaru) approached Nonō stating that they were in need of her expertise in intelligence gathering. Requesting that she infiltrate Iwagakure and gather information on their plans, Nonō initially turned the mission down but was forced into doing it after the two Root ANBU subtly threatened to attack the orphanage. Nonō agreed to work with them, and was outraged when Danzō stated that he needed a child to replace the Root shinobi who had died in order to retrieve the intel on Iwagakure. She was even more shocked when she learned that Kabuto, who had spied on the meeting, volunteered to go with them. Five years into Kabuto's life as a shinobi, he was sent on a mission to infiltrate Iwa where Nonō attacked him. She was critically wounded as a result of Kabuto's chakra scalpel, and panicking Kabuto tried to treat her, but Nonō no longer recognised him, which shocked the young man, who ran away. She was later found by Kitsuchi and another Iwa-nin.

Personality
From all indications, she is a very kind and calm woman, taking in Kabuto and then later begging for them to let him stay even when they could not afford it. She also displays a great capacity for generosity, giving the young Kabuto her glasses. Danzō noted that though she was a member of Root, she was unable to lose her emotions which was why she did not suit Root.

Appearance
She is a young woman with shoulder-length light-coloured hair covered by a coif and light-coloured eyes. She wore a black, loose-fitting gown with a white apron over it with sandals. She also wore circular glasses before giving them to Kabuto. She replaced them with a pair of square glasses shortly after.

During her encounter with Kabuto in Iwagakure, she wore the village's flak jacket and forehead protector.

Abilities
Not much is known about her abilities other than she was skilled in medical ninjutsu and was able to heal wounds. She was also noted to be an elite shinobi in the area of intelligence gathering as Danzō stated she was the only one that could be trusted with a mission of such high importance and risk.

Trivia

 * means 'a certain person'.
 * An is actually a type of miko that used to be quite common in Japan. Instead of belonging to a certain temple, these miko would travel around the country, performing various duties like prayers, exorcisms, oracle work, and sometimes even entertainment and prostitution. It is said that the practice of arukimiko comes from a miko called  — a name said to have come from the word  — who travelled around the county preaching the Shintō faith. When Danzō mentions that she didn't fit in Root because she couldn't kill her emotions, the old man actually says to Danzō:.
