Rukia Abarai (阿散井 ルキア, Abarai Rukia), formely known as Rukia Kuchiki (朽木 ルキア, Kuchiki Rukia) is the current Captain of the 13th Division, succeeding the former captain Jūshirō Ukitake after previously serving as lieutenant. Rukia is the adoptive sister of Byakuya Kuchiki, the younger sister of Hisana Kuchiki, a friend of Ichigo Kurosaki, the mother of Ichika Abarai, and the wife of Renji Abarai. Initially born into a lower class, Rukia retains her modesty, even as an adopted member of the nobility. She is graceful and "clean", yet chooses to talk to ordinary people. However, her cool and lone demeanor often forces her to hide her personal troubles, even from her friends. According to Ukitake, Rukia never opens up her heart, and has difficulty making friends. Rukia is clueless about the ways of the modern Human World. She is very good at acting, having acted her way through a number of tough situations, such as getting out of trouble with school teachers and convincing the Kurosaki family to let her stay at their house. Rukia always has trouble finding clothes that fit her, especially when inhabiting a Gigai in the Human World, leading to her stealing clothes from Ichigo's sister, Yuzu. She likes to climb to high places. Rukia likes everything rabbit-themed, and becomes quite sensitive when someone insults her obsession with them. People often have difficulty understanding her drawings, which are typically rabbit-like, and doesn't like it when people complain about their quality. Rukia's favorite foods are cucumber, eggs, and rice dumplings. Quite often when Rukia is annoyed with a situation or when conversing with people that exasperate her, her common tic/phrase in reaction is either "nonsense!" ("たわけ!", "tawake!") or "nonsensical fool!" ("たわけども!", "tawakedomo!")

Hisana Kuchiki (朽木 緋真, Kuchiki Hisana) was Rukia Kuchiki's older sister and Byakuya Kuchiki's wife. Hisana was a kind, caring, and loving woman. She was soft-spoken and always polite. Hisana felt very guilty for leaving Rukia behind to save herself, feeling she did not deserve to be called her sister. She loved Rukia greatly, but could not care for the both of them.

Kiyone Kotetsu (虎徹 清音, Kotetsu Kiyone) is the lieutenant of the Fourth Division under her sister Isane Kotetsu. She is also the former co-3rd Seat officer of the Thirteenth Division in the Gotei 13 under Captain Jūshirō Ukitake. She shared her previous position with Sentarō Kotsubaki. Kiyone is the younger sister of Isane Kotetsu, the captain of the Fourth Division. Unlike her sister, Kiyone is very open and excitable, but she does share Isane's sense of loyalty. She holds her captain, Jūshirō Ukitake, in high regard and always tries to impress him in any way possible, even if she has to ruin her partner Sentarō Kotsubaki to do so. She frequently engages in competition with Sentarō over who admires and/or loves him more, much to Ukitake's exasperation. Like other female Shinigami, she is a member of the Shinigami Women's Association. She is even willing to help Suì-Fēng pin Ukitake to a tree with kunai knives and slash open his clothing so she can have "sexy" photos of him, although she does jabber "I'm sorry, I'm sorry!" while she photographs him.

Isane Kotetsu (虎徹 勇音, Kotetsu Isane) is the Captain of the 4th Division and former lieutenant under Captain Retsu Unohana. Her lieutenant is her younger sister, Kiyone Kotetsu, the former 13th Division's 3rd Seat. Isane is generally quiet, shy, and observant, with a strong sense of loyalty. She can be impatient in the face of an enemy, rushing after enemies she has no chance of defeating, including the seemingly unstoppable Sousuke Aizen. She looks to Unohana as a mentor and mother figure. It is noted by Unohana that Isane suffers from frequent and recurring nightmares, which are often odd or whimsical in their contents. For example, she once had a nightmare involving kamaboko (a fishcake made of pureed surimi), which she intensely dislikes. Also, according to Unohana, she rarely talks in a girly manner. Her favorite food, on the other hand, is porridge, to the extent that she is capable of eating it as the three main meals on the same day. When Isane has time off, she goes to see her sister Kiyone and vice versa. They are very close sisters who enjoy meeting up and having fun together. Recently, her favorite place to hang out was the Kuchiki estate, in the "secret base of the Shinigami Women's Association". She is a notable member of the latter Association, where her meek nature occasionally gets her in trouble with group activities, including getting captured alongside Nemu Kurotsuchi when attempting to take a picture of Byakuya Kuchiki. Believing that the nutrient level of porridge was very low, Isane started eating porridge when she passed 170 cm in height as she did not want to get any taller. However, she did not stop until reaching 187 cm, her height being another source of frustration for her. Once, after hearing of how sleeping helps children grow, she decides to not sleep again in order to halt her growth.

Kyōkotsu (狂骨) is one half of the manifested spirit of Shunsui Kyōraku's Zanpakutō. Kyōkotsu is very different in temperament from her counterpart. She views battle as a type of game, and constantly toys with her opponent instead of killing them, leading Nanao to note she has no emotions. However, she becomes angry if someone prevents her from fighting in this manner. According to the taller half of Katen Kyōkotsu, she can be simultaneously innocent, ingenuous, merciless, and cruel, and tends to be dark and malicious. She immediately enters an unquestioning fighting mode as soon as someone approaches her, and attacked Nanao when the latter simply touched her shoulder. Rangiku Matsumoto notes she acts very un-ladylike; she refuses to wear beautiful clothes, incapacitates all of the men who had pledged to serve her, and does not like eating sweets. However, she likes flowers, and often stares at falling blossoms and various fruit trees; Nanao ends up befriending her by putting a blossom in her hair and taking her to see the blooming peach blossoms. She is very cooperative when treated decently, willingly giving Nanao her Zanpakutō when asked to do so. She can be somewhat meek, refraining from eating anything while at a bar with five other people because she did not believe she had permission to do so.

Katen (花天) is one half of the manifested spirit of Shunsui Kyōraku's Zanpakutō. While under the influence of Muramasa's brainwashing, Katen has a habit of covering her mouth with her sleeve. She is very hostile toward Shunsui, refusing an offer to settle their differences without fighting and calling him arrogant for offering. She always speaks for both herself and Kyōkotsu, who follows her lead, and implies they left Shunsui because of his "dull" personality. She derides Shunsui's practice of being a gentleman in battle, and claims she has no qualms with using full force against him. Initially, Katen and Kyōkotsu are very loyal to Muramasa, holding Shunsui off and refraining from killing him on Muramasa's orders. However, they turn on him once they learn of how he was lying to and using the Zanpakutō spirits to achieve another goal. After being freed from Muramasa's control, Katen is on much better terms with Shunsui, playing a card game with him in their free time and painting on his face when she wins. She is fond of playing the shamisen in her free time, and frequently drinks sake with Shunsui. She is very lazy, refusing to leave a drinking party in order to hunt Tōjū alongside Nanao Ise because she considers it "back-breaking work", and likes to enjoy the finer things in life. She has a sense of aesthetics for beauty, and is irritated when Nanao attempts to throw a party underneath a barren tree. She is somewhat rude toward Nanao, referring to her as "young lady" instead of her real name. However, she is happy when Nanao manages to befriend Kyōkotsu.

Kanae Katagiri (片桐 叶絵, Katagiri Kanae) was a Gemischt Quincy and a former maid in the service of the Ishida family. She later became the wife of Ryūken Ishida and the mother of Uryū Ishida.

She's aware of the responsibilities which weigh on Ryūken's shoulders as an Echt Quincy and she is always ready to offer him advice. She is very attached to Ryūken, being his protector and she can't bear to see him sad.

Rurichiyo Kasumiōji (霞大路 瑠璃千代, Kasumiōji Rurichiyo) is the clan head of the Kasumiōji Clan, as well as a central figure in the Kasumiōji Conspiracy. Her family, according to Yoruichi Shihōin, is just below the four great noble families in status, commenting that their circumstances are a bit "special". She appears to be a small child and has an attitude typical of a princess, expecting her demands to be met quickly and throwing tantrums when ignored. Despite often being self-centered, she can be sensitive to the status of others, regretting that many people got in trouble when she went off on her own. Kenryū notes that she is very stubborn. She regards it as part of her job to protect her servants and that she cannot let them die on top of being aware of her life being targeted by Kumoi. She also typically refers to herself with the royal we while using "onushi" to refer to others.

Hotaru Kanisawa (蟹沢 ほたる, Kanisawa Hotaru) was a 6th-year student at Shin'ō Academy. She was a classmate of Shūhei Hisagi, as such she was a senpai to Momo Hinamori, Renji Abarai and Izuru Kira. Along with Hisagi and Aoga she helped lead a group of academy students on a training mission to the material world. Before departing for the mission, she instructed the students to gather into groups of three, determined by scraps of paper with various markings on them had been handed out earlier, with the students possessing identical markings forming a group. The mission was to practice konsō. When Hisagi was about to end the day's training, Kanisawa was killed by a Huge Hollow. Aoga immediately tried to avenge her but was injured by the same Hollow. Hisagi and Aoga, having both survived the ordeal, would visit Kanisawa's grave during the interlude between Wandenreich's first and second attack on the Seireitei, where they lamented about how she died.

Kakyō (歌匡) was a Shinigami and a close friend of Kaname Tōsen until her murder, which was the catalyst that proceeded to turn Tōsen against Soul Society. Kakyō was described by Kaname Tōsen as a person who "followed the path with the least bloodshed", a philosophy that Tōsen proceeded to adopt himself. Kakyō's dream was to become a Shinigami, which she succeeded at, and to use her powers to maintain a peaceful world.

Izumi Ishida (石田 依澄, Ishida Izumi) was an Echt Quincy as well as the wife of Sōken Ishida, the mother of Ryūken Ishida, the mother-in-law of Kanae Katagiri and the paternal grandmother of Uryū Ishida. Izumi was a stern woman, who took her responsibilities as matriarch of the Ishida family seriously. She cared greatly about keeping the Quincy Bloodline of the Ishida family pure, due to the Quincy being an endangered race. She also cared deeply about her son, Ryūken, and was distraught when he left their residence with the infected Masaki Kurosaki. According to her son, Izumi is frustrated that her husband, Sōken, spends a lot of time away from his family, and she vents that frustration upon Masaki.

Nanao Ise (伊勢 七緒, Ise Nanao) is the co-lieutenant of the First Division of the Gotei 13, under her uncle, Captain Shunsui Kyōraku, and Vice-President of the Shinigami Women's Association. She has also formerly served as Lieutenant of the Eighth Division. Nanao 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 in an act so frightening that 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 so loves 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 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 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.

Isuzu Ise (伊勢 檍涼, Ise Isuzu) was the previous head of the Ise Clan, as well the late mother of Nanao Ise and the late wife of Shunsui Kyōraku's late older brother, Shunzan.

She is married to Ichigo Kurosaki and has a son named Kazui Kurosaki. Orihime is independent, friendly, humorous, optimistic, sensitive, caring and kind. She comes off as naive and rather clueless, which contradicts her exceptionally high marks as third highest in her grade. She studies hard because when her grades drop, she receives less financial support from her relatives. She is a member of the Handicrafts Club and likes to invent very ridiculous sports to play with Tatsuki (such as "base-cer," a combination of baseball and soccer). She tends to zone out with her mouth open and loses track of what she was thinking or dreaming about. She has an over-active imagination and gets carried away thinking of implausible scenarios, such as portraying herself as a futuristic and highly destructive robot in an assignment asking a student "How do you see yourself in the future?". Orihime likes Asian flower print clothing and comedies. While she does eat some normal food, Orihime cooks and eats unusual meals, which other people often find unappetizing. Her favorite food is red bean paste and she likes putting butter on sweet potatoes. She enjoys cheese and butter most of the time. Orihime has demonstrated that she is perceptive when it comes to people's mental and emotional state, especially in regards to Ichigo, as she is able to tell what kind of driving force is pushing someone. She additionally has a crush on Ichigo and later falls in love with him. She has exhibited traits that appear to have some connection with Ichigo, such as the ability to detect Ichigo by scent, sense his Spiritual Pressure even when masked by the Visored, and an awareness of what mood Ichigo is in, sensing his feelings of anguish, disappointment, or worry, even feeling pain herself when Ichigo is hurt.

She is a proud lesbian, who seems happy almost all the time. She appears to be attracted to Orihime Inoue whom she calls "Hime," meaning princess, or this could just be a shortening of her name. She hugs Orihime every chance she gets, and usually compliments her and fondles her chest. Chizuru also makes advances toward Michiru Ogawa. She is usually stopped by Tatsuki who always hits her to get her off Orihime, but if anyone else interferes or says anything negative about Orihime, she goes into a rage.

Homura (ほむら, Homura) is the elder sister of Shizuku. Along with her brother, she was a major antagonist of Bleach: Fade to Black. Her name was given to her by Rukia Kuchiki. While Homura normally appears as a sweet, cheerful, and energetic teenage girl, she is actually rather stubborn, single-minded, selfish, hostile towards anyone other than Rukia and Shizuku, and somewhat naive and misguided. These traits lead her to act irrationally in most situations, due to a century of suffering in Hueco Mundo. Due to a traumatic encounter, she harbours a deep hatred of Shinigami; mocking them and claiming they only reap everything away from the very souls they supposedly protect. She shows no fear of dying. She holds Rukia so dear she is prepared to take extreme measures to be with her, even if it means she and Shizuku fusing with her, which would destroy Rukia.

Momo Hinamori (雛森 桃, Hinamori Momo) is the lieutenant of the 5th Division, formerly under Captain Sousuke Aizen and currently under Captain Shinji Hirako. Momo's main pastimes are reading and drawing. Due to her talent in drawing, she has overseen work for book illustration in the Shin'ō Academy. Her love for books has developed since Aizen regularly gave her the books he had read. In his absence, she frequently visits the library. She attends the ikebana lessons held by Captain Retsu Unohana. She frequently visits Tōshirō's grandmother in Rukongai. Her favorite food is peaches, and she does not like plums. She sometimes bakes cookies, and once made a batch in the shape of Aizen's glasses. Momo is generally an upbeat, easy-going, and friendly girl. She has a strong friendship with Tōshirō Hitsugaya, whom she grew up with, repeatedly calling him "Shirō-chan" as in their past together (or occasionally as "Hitsugaya-kun"), despite his higher rank and complaints about this. Though normally kind, her rare bouts of anger can appear rather menacing, such as her outrage at Captain Gin Ichimaru when she blamed him for killing Aizen. While serving as his lieutenant, Momo greatly respects and admires Aizen. She idolizes him to the point where a letter from Aizen leads her to attack Hitsugaya, her childhood friend, and even after being stabbed by Aizen, she, proclaiming Aizen was being manipulated, asks Hitsugaya to save him. When Aizen leads an attack on the Fake Karakura Town, Momo helps to defend the town from Aizen and his forces, but she still notably refers to him as "Captain Aizen".
