Nanao is notable for being in 8th Division when she was a little girl, and enjoyed being read to by former lieutenant Lisa Yadōmaru, something they did regularly each month around the time of the first. Eventually between the period when Lisa was forced to hide alongside the other transformed Vizards and the present day, she worked her way up from being Shunsui's subordinate to his lieutenant.
Soul Society Arc
Nanao is first seen when Yasutora Sado makes his way to the Eighth Division’s offices. She was talking to Shunsui Kyōraku, who was teasing her, calling her “Nanao-chan!” ("Little Nanao!" in the English Dub) which she hate s. She later spreads flower petals so that Kyōraku can make his grand entrance. But as usual he starts teasing her and she gets mad at him and dumps the rest on him. During the fight between Kyōraku and Chad she stays out of the picture, and then receives a message from the Onmitsukidō, informing her of the murder of Sōsuke Aizen. She runs to Kyōraku to tell him, and then as they turn to leave, she notices that Chad, who has been cut by Kyōraku, is not dead. She asks permission to deliver the finishing blow, but Kyōraku says no and instead tells her to take him to the Fourth Division .
Much later, during the day of Rukia Kuchiki's execution, she finds Kyōraku at his usual spot up on a roof. She puts up once again with his teasing as she tries to hurry him to the Sōkyoku Stand. As he asks her what he should do, she tells him that no matter what she thinks or advises, he would still do what he wanted to. “Don’t worry,” she also said, “I will stay several steps behind you, so as not to get caught in trouble, but I will follow.” After the failed execution, Nanao follows Kyōraku and Jūshirō Ukitake to the place where they could battle Yamamoto without getting anyone else implicated. She then describes the spiritual pressure that is Yamamoto, but while trying to take out her Zanpakutō, she is caught in Yamamoto’s stare and is suffocated by his spiritual pressure. Kyōraku breaks the eye contact to save her, and brings her to a safer spot. She then realizes that it is not only difficult to win against Yamamoto even with two Captain's on their side, but it is next to impossible
Nanao is a youthful girl with black hair normally kept pinned back, she has blue eyes and wears glasses. She notably resembles Lisa Yadōmaru
, a member of the Visoreds
and the person who preceded her position as the 8th Division Lieutenant. The resemblance is likely intentional on her part, as she is hinted to have greatly respected Lisa before she became a Visored, when Nanao was a child first joining the Gotei 13.
