Relatives[]
Earl Seiran[]
Earl Seiran is Kiki's father and head of the Seiran family. He is always looking for a marriage partner for her, stating that it is his duty as the head to set her up with someone suitable. He tends to have many arguments with Kiki, because of their contrasting personalities, but they seem to have a good relationship. Earl Seiran has trained Kiki since she was young, giving her all the skills to be a better house head than her predecessors. He is anxious to see Kiki replace him as house head, so he can retire in peace. He likes to be called Dad, but Kiki always refuses, calling him Father instead. He exclaims Kiki's cold voice is just like her Mother's. Count Lugis is an acquaintance of his.
Countess Seiran[]
Countess Seiran is Kiki's deceased mother. She was dead before Kiki turned five and has been implied to have died in childbirth. Despite her absence from her daughter's life her daughter is said to have developed a personality and way of speaking which evoke memories of the departed countess. Kiki has a set of earrings from her parents that she wears at all times. Prior to her engagement, she wore one earring, and kept the other part of the pair at home, because this reassured her. Since her engagement, she is seen wearing the earrings on both ears.
Close Friends[]
Mitsuhide Rouen[]
He works alongside her as Zen's other close aide. Like everyone else, she makes fun of him a lot, usually in a deadpan voice. They work very well together, especially in combat, with their movements so in sync that it would be difficult to determine a winner if they dueled against each other. When he learned that Kiki's service to Zen came with a time limit, he became angry. He was upset not because of the fact that she was leaving but the fact that both Zen and Kiki had hid it from him for over five years. They eventually resolve their fight with a duel, with Mitsuhide requesting that Kiki see Zen's current goals through before she heads off to take over her duties as Seiran heir. They first met at a ball, when he was attempting to hide and avoid interacting with other party-goers. Kiki was doing the same thing and immediately recognized him as Prince Zen's aide. When he inquired how she knew his name and asked for hers, she told him that she would introduce herself when the right time arose. This is because she wanted him to see her as a proper swordswoman and not as a noble. The second time they met, he mistook her for a guy, going so far as to invite her to take a bath with him and the other Sereg Knight Circle trainees. He didn't connect her to the noblewoman he had met previously until some time later.
At one point, through their many years of working together, Kiki started having romantic feelings toward Mitsuhide, deciding that she would propose to him when the time was right. Mitsuhide remained oblivious to Kiki's romantic affections. While Mitsuhide is generally dense about such matters, he could have also remained oblivious because of Kiki's reserved and stoic personality. During their long partnership by Prince Zen's side, Kiki did not display overt romantic affections or attempt to court Mitsuhide, to the point that even Prince Zen was surprised when Kiki informed him that she intended to propose to Mitsuhide. When Kiki finally proposed, Mitsuhide was confused about his feelings and what the proposal meant for him. While Mitsuhide deeply appreciates their relationship and treasures their time together, he had never considered dating or marrying anyone due to his extreme loyalty to Zen, wishing to stay by his side till the end of his days. For this reason, Mitsuhide ultimately turns Kiki's proposal down. Kiki doesn't hold it against him, and they continue to remain best friends and partners.
Zen Wistaria[]
As one of the two aides to the second prince, Kiki is extremely close to Zen. Along with Mitsuhide, she accompanies Zen almost everywhere he goes. A lot of times, she keeps Zen in check. She, like many others, follows Zen because of other reasons besides his status which Zen is fully aware of and appreciates. Until she met Zen and he asked her to work with him at the palace, she didn't have any close bonds with her peers, preferring to keep to herself and rely only on herself. Zen and Mitsuhide coming to her aid when she was caught in a duel with Hisame as a teenager showed her how comrades could enrich her life. While she has a deadline to return home and take over Earl Seiran's responsibilities as his heir, she negotiated with her father so that she could serve Zen for a longer period. Zen says that he is one of the people that knows Kiki best in the whole kingdom. Both Kiki and Zen have considered each other as potential marriage partners as they are well matched in both demeanor and political status, but they ultimately decided that their platonic bond was the superior one.
Shirayuki[]
Kiki and Shirayuki share a great amount of respect for each other and have each other's backs. Since they are the only two girls in their friend circle, they often share a room on trips and vacations. On these occasions they are seen to bond, sharing advice and stories. Shirayuki enjoys it when Kiki does her hair. Shirayuki has stated that no matter where Kiki is in Clarines, she hopes to meet her in good health. Shirayuki has also been seen to blush when Kiki dresses up, because she considers her to be a very beautiful woman.
Obi[]
As Prince Zen's aides, Obi and Kiki often work closely together, having fought together side by side on many occasions. While Kiki was originally wary of Obi due to his previous line of work, she warms up to him after he demonstrates his loyalty to Zen. They hang out together when their times off coincides with each other and also enjoy teasing each other.
Romantic Partner[]
Hisame Lugis[]
Hisame is Kiki's fiancé, and she is increasingly shown to be more relaxed and open around him. While Hisame has been a suitor for Kiki's hand in marriage since childhood, their relationship started on the wrong foot because as a teenager, he attempted to win her hand in marriage via a duel. He believed she would be more accepting of the proposal if she lost in a contest than through a prolonged courtship. With the maturity that comes with age, as an adult, he properly proposed to Kiki and became engaged to her. They originally formed a temporary marriage agreement out of necessity during the Bergatt incident to draw out those who were attacking Kiki's potential suitors. However, they reaffirmed their engagement after Kiki's marriage proposal to Mitsuhide was turned down. After their formal engagement, they spend more time getting to know each other, with Hisame occasionally attending soirées with Kiki as her guest. They openly communicate about their expectations of each other in their relationship, with Kiki suggesting that they eat breakfast together when they are in the same city. Kiki has stated that they are well suited to each other, while Hisame has told her that she can set whatever standard that she wishes for in their relationship.
