Ririchiyo Shirakiin (白鬼院 凜々蝶 Shirakiin Ririchiyo) is the main protagonist of the story who once resided in room number four of Ayakashi Kan, and was the client of Soushi Miketsukami. She tends to put a cold front because it is her only way to cope the things she was put through. Ririchiyo finds herself constantly distressed about not being able to communicate with people properly and decides to move in to Ayakashi Kan in order to be alone. She later befriends Karuta and Banri, both of which attend the same school and live in Ayakashi Kan. She can be called a tsunshun instead of tsundere due to the fact that she gets depressed (shun) instead of becoming lovestruck (dere) after behaving in a conceited manner.
Ririchiyo is killed at the age of sixteen after trying to stop the enemy youkai raid after they killed Soushi. In Part 2, she is reincarnated and now resides in room one of Ayakashi Kan, but has amnesia due to the trauma of losing Soushi after he protected her.
Ririchiyo is a petite young girl. She has long violet hair, violet eyes, and full legs. However in the anime she is noted to have long black hair. Her cheeks are noticeably chubby.
She wears many different types of clothes, but is mostly seen wearing her black deep V-neck dress with four buttons on each side and no sleeves. Underneath, she wears a white long-sleeved ruffle blouse. She is often seen wearing plain black shoes with gray thigh-length socks.
In her youkai form, she has two curved horns along with a flower on one of her horns and is taller by a few centimeters, as she wears Zori. Her outfit is a dark red hakama with a miniskirt. Below her hakama she wears black arm bands and white bracelets on each wrist. There is a golden chain-like belt around her waist with a Hannya mask hanging on the back. A naginata is present when she transforms; the traditional Japanese bladed, spear-like weapon is slightly taller than her own height, and is decorated with red tassels on each end of the shaft.
As the result of her isolated childhood, Ririchiyo harbored a cold and brooding personality. She would inadvertently lash out at others and interacted poorly with people. This was the reason for her decision to move to Ayakashi Kan: she wanted to live on her own. Her plan, however, was disrupted by the arrival of Soushi, who unexpectedly entered her life. At first, she was initially surprised and uninterested by his offer to form a contract with her, but after his persuasion that his one duty in life was to serve her, she created a true connection with him, and he became her Secret Service agent in the process.
All her life she had been respected merely for her family or social status, yet because of his genuine kindness and services towards her, Soushi was the only one to take interest in her for who she was. Though she continued to treat him with some (unintended) bitterness, she began to warm up to Soushi, and eventually those around her as well. Over time, she came to see her friends as an almost family, and although her slight abrasive nature remained, she reached out to people more in attempt to better understand them.
During this course of her inner development, as Ririchiyo spent more time around Soushi, she found that she was falling in love with him. Although she internally denied this and was confused by her increased heart rate whenever she was around him, she at last admitted her feelings to him. This shows that the icy, impersonal girl she once was had been replaced by a kinder young woman.
Ririchiyo was somewhat hesitant when it came to Soushi devoting himself to her. At first, she did not believe that their contract was necessary because she feared that she would just hurt him in the end. Ririchiyo rejected the contract many times, causing Soushi to believe that life would be meaningless without him being by her side so every time she would reject him, he would insist on her disposing of him with a katana, which she declined every time. There is a moment in which Soushi agrees to their contract being void because of the way Ririchiyo saw him at one point, claiming he was "morally corrupt", due to him toying with another girl's feelings. This caused Soushi to believe that he was not fit to be her servant. However, they did finally seal their contract when they both apologized to each other, thus forming their master/servant relationship. Soushi is willing to go to extreme lengths to protect Ririchiyo, whether or not it means putting his life on the line.
As the manga/anime series progresses, their relationship begins to develop more into a friendship, but soon it starts to develop even more in which Ririchiyo starts to fall in love with Soushi. It is later revealed that Soushi has been yearning to meet Ririchiyo face to face ever since he first encountered her at her fiancé's estate. It is hinted that he has had feelings for her since then, even though they were never properly introduced to each other until Ririchiyo moved into the complex. In the anime, the two become a couple after Ririchiyo discovers that Soushi was the one writing to her ever since childhood, and that they "noticed" each other. The two of them confess their love at a park. Later on in the anime, Soushi tells Ririchiyo that he has a dream in which he wants a family with her. They don't have children due to the fact that he is killed but is reincarnated whenever he is killed. This means that his personality and feelings change, but he still tries to act like the original Soushi to please his master, Ririchiyo. However, Ririchiyo eventually finds out the truth, so they cancel their contract. There will always be moments from the old Soushi, however.
Sorinozuka is Ririrchiyo's childhood friend. Though he considers himself her "big brother" and looks out for her, she does not think of him as more than a neighbor, nor does she appear to appreciate him that much. However, he is unfazed by her normally cold demeanor and continues to help her whenever he can. He also points out that Ririchiyo does care about others, as she wrote him an apologetic letter after the two got into a fight. She does indeed show concern for him, though she'll never admit it out loud.
Kagerou was Ririchiyo's fiancé. They used to write letters to each other when they were young and Ririchiyo would always wait for his letters. Later on, Kagerou tells Ririchiyo that Soushi was the one writing the letters and not him. Their parents were the ones who set up their arranged marriage. He said that he came to Ayakashi Kan because he wanted to entertain her. Once, she visited Kagerou's house.
At a first glance, Nobara gave Ririchiyo the chills. Nobara is constantly infatuated with Ririchiyo's innocent appearance, claiming that she hopes that she and Ririchiyo may get along. "Of course, I mean this sexually!" This tends to make Ririchiyo very creeped out by Nobara's perverted persona. But she does find Nobara a nice person who makes a decent friend, despite her fetish with Ririchiyo's body.
Ririchiyo immediately thinks the exact same thing other people would think after meeting Karuta: she is odd. Slowly, though, Ririchiyo becomes charismatic towards Karuta by constantly worrying about her getting into trouble and by giving Karuta food. Immediately after receiving food from her, Karuta proclaims she loves "Chiyo-chan". Ririchiyo is embarrassed by this and dismisses it as Karuta only showing her gratitude. Eventually, it can be clearly seen that Karuta truly does care about Ririchiyo and that she thinks of her as her best friend.
Ririchiyo is not very fond of Watanuki, as Watanuki is not very fond of Ririchiyo either. They can be seen having silly, pointless arguments, but nothing brash enough to cause any drama. Ririchiyo finds it humorous on how Watanuki claims to be a delinquent, yet he acts most the time as a bright and kind person. Although they do bicker, they consider each other friends.
Zange would most likely be Ririchiyo's least favorite person, as he tends to tease her a lot. However, at times, he does give Ririchiyo tips on how to communicate better with people and consider others friends.
Ririchiyo was born into the Shirakiin family, a wealthy family of important status; it was mentioned they do clothes and fashion. But because of this she suffered bullying and humiliation at school: her classmates told her she was a boring person and that she shouldn't get full of herself just because her family was rich. That is why Ririchiyo puts up a front and developed her bad habit of verbally abusing people. Even her teachers vainly defend her from the bullies in hopes of getting recognized by her family.
Since Ririchiyo was of demon ancestry, her family kept her in intensive protection at home - which was nothing more than isolation. She has a younger sister whom she grew jealous of, merely because of the fact that she had more attention and love from their parents than herself. Knowing this, Ririchiyo's father didn't hesitate in slapping her for her yearning of her little sister's place. He told her that she didn't know better, and instead of her suffering, her younger sister had it much worse for having to live under her "shadow". Young Ririchiyo then only stood shocked and unmoving, touching the cheek her father had violated.
During her childhood she would write letters to her fiancé, Kagerou, for comfort. Ririchiyo loved to write letters in special stationery sets, and often would write one out of modesty and kindness. Since she couldn't talk to people properly, she vented her feelings in these letters, and apologized sincerely once to Renshou after a fight they had. She wrote her feelings especially in the letters she sent her fiancé, after which she eagerly awaited his reply.
Ririchiyo Shirakiin moves into the high-security Maison de Ayakashi apartment complex. There, she finds herself assigned a Secret Service agent named Soushi Miketsukami, who claims to have known her for a very long time. Ririchiyo is reluctant to have Soushi as her SS agent, particularly because she doesn't feel worth protecting as her family household has taken up much of her being. She meets other tenants in the apartment complex; her childhood friend Renshou Sorinozuka, with whom she claims to be "just neighbors"; a quiet girl named Karuta Roromiya; and Sorinozuka's Secret Service agent, an odd woman named Nobara Yukinokouji. One night, a burglar breaks into the complex to try and rob Ririchiyo, only to learn that Soushi, along with the other Secret Service agents in complex, have the power to channel the spirits of monsters (youkai). Nobara channels an ice spirit, and Karuta is a Gashadokuro (a large skeleton made from the bones of people who died of starvation). Having been protected from a gunshot by him, Ririchiyo accepts Soushi as her bodyguard.
Ririchiyo is out shopping and Sorinozuka's goal is to keep her out the complex until 6. At the mall, Ririchiyo sees a commercial about a dog and thinks how similar Soushi is to that dog. When they return to the complex, they are told that Karuta is missing. As they set out to find her, Ririchiyo is forced to show her youkai side when she is captured by another youkai. After defeating the youkai, Soushi, Ririchiyo, and Sorinozuka go back to the complex to find that the tenants of the complex were setting a welcome party for Ririchiyo.
Ririchiyo attends a high school enrolled as a top student. She intends to not insult her classmates and to meet new friends, but this doesn't turn out as planned when two boys at her school insult how wealthy she is. After dealing with the stress of making a good impression at her new school, Ririchiyo notices Soushi turning down an admirer. After questioning him about it, her emotions get the best of her and this time, the contract is terminated. Ririchiyo regrets terminating the contract and hurting Soushi after all he has done for her, without even saying one last "thank you". At the social gathering, the boys who insulted Ririchiyo earlier continue to torment her until Soushi arrives and splashes them with water. Ririchiyo is happy that Soushi returned and splashes water on herself, claiming that she is responsible for her agent. Ririchiyo forgives Soushi and lets him continue to be her agent, pinky-promising that they will never be separated ever again. In episode 4 in the elevator scene, Soushi asks if something is bothering her. She replies, "I'm alright", but it turns out that he's the one that's not. He tells her that only a few days ago he was extremely happy just being with her, but right now every hour his need to see her becomes more and more demanding, which implies that he is growing more and more attracted to her. He also says that he was quite jealous when Natsume said that he saw Ririchiyo last night. As he tells her this he raises her hand to his lips and kisses it, which causes her to blush and push him away from her, claiming him to be too close.
In Part Three, all of the residents get a letter from their reincarnated selves, saying what will happen in the future if they don't stop the attack. All characters are current the same ages as before.
