Nanao Ise

"The desk-work expert who takes care of the division's administrative matters on behalf of her captain, who hardly performs any normal tasks." - Tite Kubo

is the co-lieutenant of the First Division of the Gotei 13, under Captain Shunsui Kyōraku, and Vice-President of the Shinigami Women's Association.

Appearance
Nanao is a slim and youthful girl with long black hair normally kept pinned back, with flat bangs that hang to the right side of her face. Nanao also wears a standard Shinigami outfit. She has slightly light blue eyes that have a deep tint of violet and wears glasses with a slight oval shape to them. As a child, she had rounder glasses with chin-length hair that framed both sides of her face.

Seventeen months after Aizen's defeat, Nanao has her bangs tucked behind her right ear.

Personality
She is a very serious and pragmatic person who often puts up with her captain's silly antics, but like all lieutenants, she is extremely respectful of her captain and follows his instructions without hesitation. She is almost always carrying a heavy book. Nanao is often accosted by her captain, whose teasing takes various forms. Nanao's usual reaction is to scold him or hit him with something, usually a fan. When she is particularly annoyed she takes off her glasses, though her face has never been seen while doing so. Apparently this act is quite frightening, as most people who see it are reduced to gibbering wrecks just by witnessing it. Even the sadistic, cold-hearted 12th Division captain, Mayuri Kurotsuchi fell victim to this intimidating spectacle.

In her free time, she likes to go shopping, but even more to read, and often visits the library. She is on good terms with fellow reader Momo Hinamori; she even brought her books during her hospitalization. Nanao also has an article serialization in Seireitei Communication, titled "Please be Moderate", which is very popular, especially among the male readers. Nanao is known to be an excellent calculator, a skill very handy, given that she has to do even most of her captain's paperwork. Her favorite food is sweet bean jelly, and she does not like powdered green tea, a trait which is interestingly shared with her captain.

Nanao is the Vice-President of the Shinigami Women's Association, but is usually the one who attempts to maintain and control the meetings due to the juvenile actions and behaviors of President Yachiru Kusajishi. Yet while she attempts to be the main moderator, Yachiru usually has higher say on everything from budget decisions to activities done by the club making any of Nanao's comments or advice worthless. She is also frequently at odds with Shinigami Men's Association leader Tetsuzaemon Iba, of whom she usually forces her superiority and control regarding the influence and power she and the Women's Association have over his association.

History
Nanao Ise was the daughter of Shunsui Kyōraku's deceased older brother and the previous head of the all female Ise Family. After the death of her father, she overheard her mother giving Shinken Hakkyōken to Shunsui Kyōraku in order to protect it. She later attended the Shin'ō Academy where she discovered that she could not utilize an Asauchi in the same manner as other Shinigami. However, her heightened abilities in Kidō enabled her to take the exams early and graduate regardless of this. She was assigned to the Eighth Division and her new adoptive parents, an elderly couple, were very proud of her for such an accomplishment. Over the years she had caught glimpses of Kyōraku, recognizing his kimonos, that were similar to her mother's kimonos, and the hairpins he wore which she was sure did belong to her mother. She concluded that her new captain was the mysterious person her mother entrust the Holy Sword to.

Nanao was notable for being in the Eighth 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 of time when Lisa was forced to hide alongside the other transformed Visored and the present day, she worked her way up from being Shunsui's subordinate to his lieutenant.

Soul Society arc
When Yasutora Sado makes his way to the Eighth Division’s offices, Nanao is talking to Shunsui Kyōraku, asking him if she should handle Sado, as he's only a Ryoka. Kyōraku teases her and calls her “Nanao-chan!”, to which she responds by asking him what he means and smacks his hand with a fan. She later spreads flower petals so that Kyōraku can make his grand entrance in front of Sado. But when he starts teasing her, she gets mad at him and dumps the rest on his head.

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 sleeping 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 follow you at a safe distance... so that I will not get dragged into anything.”

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's, 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 transports her to a safer spot through the use of Shunpo. She then realizes that it is not only difficult to win against Yamamoto even with two captains on their side, but it is near impossible.

She points out there is some data that is unrelated to the Hōgyoku. They then stumble upon information that Aizen is trying to make a copy of the Ōken using Karakura Town.

The Thousand-Year Blood War arc
While the captains are in a meeting, the lieutenants gather and discuss the situation with the Wandenreich and recent disappearances of Hollows and Rukongai residents. She listens as Izuru deduces that Shinigami were likely involved in the disappearance of the Rukongai denizens. When the Wandenreich attack Seireitei, Nanao notices the assault and rushes outside.

Nanao visits Shunsui after the Wandenreich assault and complains that he does not answer her when she knocks on the door. Shunsui states that this may be the last time they meet and apologizes. Shunsui later becomes Captain-Commander and appoints her as his co-lieutenant of the 1st Division along with Genshirō Okikiba when he moves to that Division. She is also present with Shunsui when the Wandenreich invade Soul Society for the second time.

Nanao stands close by her captain as he is confronted by Jugram Haschwalth, who is prevented from approaching or attacking due to a specialized Kidō barrier, Hakudan Keppeki. She explains the ability of the barrier, to which Haschwalth acknowledges who she is and her skill in Kidō. He then asks her whether the other captains are capable of this Kidō spell, to which she admits they are not. Haschwalth states that it is unfortunate because if they had been they would have been able to die fighting instead of being executed. She and her captain are then startled by an explosion not far from where they are.

She and her captain then listen to Kisuke Urahara's message regarding Bankai recovery. Later, when Haschwalth draws his sword and states it is his role to tip the balance in favor of the Wandenreich, Shunsui moves in front of Nanao as the wall behind them is destroyed. Revealing he had gradually absorbed the Reishi on his side of the barrier, Haschwalth notes it took him a considerable amount of time to do so and says it is a splendid technique. Asking Haschwalth if she should feel honored, Nanao makes a motion with her hand, causing a wall of hexagons to appear as she reveals she created a new wall while Haschwalth was absorbing Reishi. When Haschwalth notes this wall appears to have been made with a different technique, Nanao confirms this and explains how the wall is comprised of smaller hexagonal plates joined together before asking Haschwalth if it appears to be weaker because it is not a single wall. Haschwalth confirms this before noting the appearance of it being weak is too obvious to be true. As the Sternritter prepares to attack, he receives an order to leave, surprising Nanao.

Upon observing the light of Auswählen light rising up from the Seireitei, Shunsui tells Okikiba and Nanao that he may have to leave the Seireitei, saying that the Soul King Palace is in danger. Later, Nanao is present in the laboratory being used by Urahara. When an angered Kenpachi Zaraki begins to approach Urahara after the latter prevents him from leaving to search for his lieutenant, Nanao confronts him and reminds him that he has a duty to perform here and that his division members will be able to search for Yachiru much faster than he can. After a minute or two, Kenpachi admits she is right and backs off, prompting Urahara to give a sphere to Nanao to charge with her Reiatsu. While in the laboratory, after the door to the palace begins to disintegrate, Nanao notes that the absence of Ukitake's vast amounts of Reiatsu is causing this, but she is interrupted by Lisa, who has arrived with the other Visored in shihakushō, and informs Nanao that there's no way they're going to let things go.

When the Shinigami enter the Royal Realm, Nanao runs alongside Shunsui through the city as Lille Barro begins sniping the Shinigami. However, he does not hit Nanao, and she accompanies Shunsui as he manages to get close to Lille. Shunsui applauds Nanao's Shunpo skill, and he tells her that she should return to the others since the situation is dangerous. However, Nanao refuses, and Shunsui instead tells her to tell the others to go on without him, which she accepts. Before Nanao leaves, she tells Shunsui that if he dies, she will shave his chest hair off.

Nanao returns to the other Shinigami, saying that they should go on ahead and she will return to assist Shunsui. Soon afterward, Nanao finds Shunsui heavily injured and closing his eyes, prompting her to wake him up and beg him to take her Zanpakutō despite the promise he made to her mother. When Lille appears behind Nanao and attacks, Shunsui moves both of them to a pocket dimension within Lille's shadow using Kageoni and confirms that Nanao knows about her mother before deciding to return her Zanpakutō to her as Kyōkotsu appears behind Nanao.

Nanao expresses disbelief at Kyōkotsu being her Zanpakutō, only for Shunsui to correct himself by saying that Katen Kyōkotsu created the younger girl in order to store Nanao's Zanpakutō. After explaining the history of the Ise family and its curse tied to their inherited Zanpakutō, Shunsui reveals that Nanao's mother, his step-sister, entrusted the Zanpakutō to him, which he gave to the younger girl of his Zanpakutō spirits to hide, prompting the girl to pull the wrapped Zanpakutō out of her face. Nanao states that she understands Shunsui did not want to give the Zanpakutō back to her before revealing that she has decided to accept the curse and that she believes the person she decides to love would also believe the curse is ridiculous. Shortly afterward, Nanao emerges from a shadow on Lille's forehead before blocking a blow from him with the wrapped Zanpakutō, sending her flying down onto a building below. As Lille demands to know if she will challenge him alone, Nanao unwraps her Zanpakutō, Shinken Hakkyōken.

As Nanao prepares to attack, Lille informs her that her sword is so bright he can't see the blade. Upon learning this, Nanao asserts that she is glad that Lille cannot see the blade as Shinken Hakkyōken reflects the abilities of the God it is facing against and this means that the sword is diffusing the light that Lille is emanating. Nanao then moves in to attack Lille but he blocks it with is left arm. While the blade manages to cut off his hand, Lille is able to parry the attack and push her back. Lille derides her for trying to attack him with a sword that lacks a proper blade and prepares to unleash an attack meant to kill her. The preparation of Lille's attack causes a shadow to appear behind her from which Kyōraku emerges, coming behind her, placing his hand alongside hers in order to help her with controlling the unfamiliar sword.

Powers & Abilities
Kidō Expert: Nanao is skilled enough to perform low- and mid-level spells without incantation. Nanao claims she was appointed to her position as lieutenant solely due to her ability in Kidō. She is skilled enough to easily create intricate and advanced spells like Hakudan Keppeki within a small amount of time when given the right information. She was also skilled enough to quickly create a new seemingly more powerful hexagonal barrier to stop Haschwalth, despite stating it looks weaker, which he complemented her even more for because he would have to resort to a more violent method to break through it.

Shunpo Expert: Initially, Nanao is only proficient enough in Shunpo to keep up with most lieutenant-level Shinigami. When Shunpo masters Shunsui Kyōraku and Jūshirō Ukitake were fleeing Genryūsai Shigekuni Yamamoto, she was able to keep up with both captains, though she was exhausted from struggling to keep up after a while. However, by the time that the Gotei 13 invade Wahrwelt, Nanao improves her Shunpo skill to the point where she can keep up with her captain's speed without tiring, something which Shunsui compliments and praises her for.

High Spiritual Power: Being a lieutenant of the Gotei 13, Nanao boasts a high spiritual energy.

Zanpakutō

 * Shinken Hakkyōken is a holy sword held by the Ise family, a Shinto family. Because they are in charge of rites and rituals, the members of the family do not have their own individual Zanpakutō, instead the head of the house inherited and used Shinken Hakkyōken, which is passed down from generation to generation.


 * Shikai:Shinken Hakkyōken takes the form of an ornate medium-sized bladeless sword with a flat end. Its "blade" is decorated with four inlaid diamonds, resembling the design commonly found on the wrapped hilt of a katana, and its forte possesses a tassel on either side. Instead of a tsuba, there is a ornate band guard covering an inch of the blade with tassels hanging from either side of it. The handle of Shinken Hakkyōken is only somewhat shorter than the "blade", and possesses two tassels attached to the ring at its end.


 * Shikai Special Ability: Shinken Hakkyōken has the power to take the power of a god into itself and disperse it off into the eight directions.


 * Bankai: Not Achieved

Appearance In Other Media

Trivia

 * Prior to its revelation in the manga, Nanao's Zanpakutō was shown in the artbook All Colour But The Black to be either a wakizashi or tantō, with a rectangular tsuba decorated with diamond shapes on its corners and question-mark shapes on its broad sides. She kept it concealed within her sleeve.
