Soushi Miketsukami (御狐神双熾 Miketsukami Sōshi) is the nine tailed spirit fox and is also of mixed blood (youkai and human) like the other members of SS, but he is the most powerful one. Soushi is usually calm, polite, and gentle to everyone, but has a specially soft spot for Ririchiyo Shirakiin. He blindly obeys her like a "dog" and always tries to protect her, even if his own life is at risk. He used to serve Kagerou Shoukiin.
He was killed in action at the end of Part 1 at age twenty-three, protecting Ririchiyo from a band of evil youkai. He is reincarnated but does not remember his previous life. After learning from Kagerou's mother how important Ririchiyo was for the previous Sōushi, he researches about her and becomes Ririchiyo's SS agent again.
Soushi Miketsukami is a tall, handsome young man with pale white-colored hair, pale skin, and two different-colored eyes: his left gold, the right blue. His formal outfit consists of a black suit, gray under-shirt, and maroon tie, like most of the other SS agents.
When Soushi Miketsukami changes form, he becomes surrounded by cherry blossoms and grows into a fox/human appearance. He wears a white and black Japanese hakama and trousers, with a blue sash. Miketsukami has nine white/silver tails and wields a katana. He also has white fox ears.
Before Soushi met Ririchiyo, he was a person with no identity or sense of self, no feelings. To gain his freedom from the twisted household that never gave him the nurturing needed to develop feelings, he put up a disguise that allowed him to adapt naturally into any type of situation and targeted ever more powerful women of the house. After he started to write letters to Ririchiyo, pretending to be his former master, Kagerou, he found that he was changing, and becoming a kinder person and a person who could feel—at first only imitating her, and later gaining unique feelings of his own.
Currently, he is calm, sweet, caring, possessive—and a little self-defeating. He is very obsessed with Ririchiyo and is willing to do anything for her. His compassion for Ririchiyo is shown on mutiple occasions. For instance, when two men insulted her and his huge poster of Ririchiyo.
Ririchiyo is Miketsukami's current master. When Ririchiyo declined at first for his assistance, he offered her a katana to sever away his life as it is now meaningless without serving Ririchiyo. Ririchiyo was horrified, but begrudgingly accepted after being pestered much by Miketsukami and his dog-like innocence.
He continued to serve her passionately and fervently with professions of undying loyalty, until Ririchiyo walked home from school one day, witnessing him kissing a woman he didn't have feelings for. Ririchiyo became upset and began to talk Miketsukami afoul about his unright deceit to the woman. The two later reconciled at Ririchiyo's class ceremony party after two classmates began to badmouth her behind her back. Miketsukami defended Ririchiyo, saying she was caring, kind, and very sensitive. Ririchiyo, surprised, defended Miketsukami in return, throwing in herself a cup of water for his intrusion. With a heartfelt pinky swear, Ririchiyo asked Miketsukami to be her permanent SS.
Later, after the arrival of Kagerou, Miketsukami becomes noticeably tense and even aggressive at one point; determined, it seemed, to prevent him from revealing his secret to Ririchiyo at all costs. After a tense fight, it is revealed that Miketsukami had been the one writing the letters to Ririchiyo in Kagerou's place the entire time, and that it was because of her that he had been able to develope feelings and a personality all his own. He also fell deeply in love with her over the course of the exchange, but felt that he had no right to feel the way that he did because of his past. So, since he thought that he would never have a chance of being with her due to the secret of the letters, the fact that Kagerou was her fiancé, and his own dark past; he decided that he would satisfy himself with simply being close to her. He dreamed of having so much more, but would not tell her so because his despicable past. Thus, with there first face-to-face meeting, he was able to introduce the real him to the girl he loved for the first time.In the manga, on chapter ten—episode twelve of the anime—Soushi and Ririchiyo finally kissed when the Time Capsule event was taking place in Ayakashi Kan. Ririchiyo left to go the playground, embarrassed because the letter she wrote was supposed to be given to her "future" self and Soushi was not meant to read its contents. Despite this, Soushi read it and told her that he doesn't deserve those words, continuing on with how being by her side is enough and that's what makes him happy. Afterwards, Ririchiyo confessed to him her love, which also made Soushi admit he returned her feelings. As a result, they became lovers despite their seven years age difference. She confessed her love for him in an attempt to give him the self courage she got after she fell in love with him. Soon after, he embraced her tearfully and told her that he loved her too. He also opened up to Ririchiyo, telling her he had a dream of wanting children and a family with her. This shows a bit more of his affection towards her - conveying his wishes. For a moment, their master-servant relationship is replaced with a relationship of lovers. When Soushi was in his apartment it is revealed that there is a "secret" room, to which he opens and it in contains over a hundred or possibly a thousand pictures of - none other than - Ririchiyo. Not to mention an especially huge one of her in the middle. Soushi's devotion to Ririchiyo is apparently more of an obsession.
In the manga, Soushi is killed while trying to protect Ririchiyo from evil youkai. When he is reincarnated, he does not remember anything from his past life, including Ririchiyo. He figures out that Ririchiyo and him had a very close bond, so he tries to act like the old Soushi. Ririchiyo though figures out, and because of this, she ends their contract. Though during the Part 2, he was very much in love with Ririchiyo that he even hated his past self. In the end of the series it is confirmed that Ririchiyo and Soushi have a child predicted by Natsume.
Kagerou was Miketsukami's former master. He served him with firm loyalty and did anything he bid, to which Kagerou quickly became bored of. When Ririchiyo began writing letters to Kagerou, Kagerou told Miketsukami to continue writing letters to his fiance, and he did, unbeknownst of falling in love and being influenced by Ririchiyo.
Zange lovingly calls Miketsukami "Sou-tan!~". They have a friendly relationship, with Zange always taking the initiative to hug Miketsukami and claim that he had missed him. They are childhood friends.
Watanuki sees Miketsukami as his rival, due to a misunderstanding in their childhood. Miketsukami didn't mean it that way and apologized to Watanuki for injuring his pride. Watanuki is a cute little cinnamon bun.
Miketsukami calls Renshou "Onii-san" due to him having an older brother figure to Ririchiyo. Ririchiyo told him to stop calling him that, and even Renshou had asked him why, even though Renshou was the one that told him to.
This young woman appeared in chapter 3 of the manga and episode 3 of the anime, confessing to MIketsukami. According to Miketsukami, she is not his girlfriend but was a neighbor. It is unknown what her name is or when or where she met him before, but she developed feelings for him and confessed but was turned down, possibly because Miketsukami already had feelings for Ririchiyo. In the anime, however, she tells him that she will leave him alone if they kiss. She is not seen again after that.
It is shown at the end of the manga's final chapter that he and Ririchiyo have a baby boy. It is implied that his son resembles him and wears glasses.
Miketsukami is the nine-tailed fox's reincarnate. To control him, his family placed him under severe house arrest, and escorted him to and from school. His room was his world; he has never met his parents. Through school, he learned to be very clever, and how to trick people. He started playing with women, starting with a maid. He moved through the ranks, trying to gain more and more freedom, and to move away from his family.
At a party with his then-mistress, the most powerful woman in his family, he met Kagerou's mother, made her pity him, and gained freedom from his family. He had intended to serve her, but instead, he got Kagerou, the first male he's ever interacted with in his life. Kagerou made him write replies to the letters from Ririchiyo.
While replying to her letters, and trying to be a form of Kagerou she'd be interested in, he found she had influenced him, and became disappointed when he saw her for the first time. Later, he found out more about her painful past when Kagerou told him. He had developed genuine feelings for her even though he had never met her before. As he saw Ririchiyo looking down with pain he wanted to protect her as he saw her very miserable.
Though he still wrote letters to her, he became more like the "Kagerou" he had been emulating. At the age of 22 he left the Shoukiin family to work as Ririchiyo's SS in Maison de Ayakashi. After the events of the raid on Maison de Ayakashi, Soushi reincarnated as himself, but he was different.
In the final chapter, Natsume 'sees' Ririchiyo and Miketsukami holding hands with a little boy.
- He is seven years older than Ririchiyo.
