    Ririchiyo Shirakiin
Voiced by: Rina Hidaka (Japanese), Hilary Haag (English)

A half-human, half-oni high school girl who transferred to Room 4 of Maison de Ayakashi in order to live alone. She yearns to be independent and constantly worries about not being able to communicate with other people properly, one of her reasons for moving. Her SS agent and servant is Soushi, a fox spirit she'd unwittingly saved, although she's not aware of it.

  • A-Cup Angst: It's not something she normally cares about, but she's notably bothered by her lack of size when it gets blatantly pointed out to her upon meeting maid #1.
  • Action Girl: Being descended from a Oni gives her decent combat capacity.
  • Allergic to Love: She assumes she must be getting sick when she starts getting anxious around Soushi. She eventually gets over it.
  • Arranged Marriage: Her family intends to marry her off to Kagerou when she grows older. Ririchiyo doesn't try to hide she hates the mere thought of it.
  • Babies Ever After: The manga ends with Zange having a vision of Ririchiyo and Soushi getting married and having a son together. It's implied that their son will be reincarnated!Soushi, who wished to be born as Ririchiyo's son in the reset timeline.
  • Badass Adorable
  • Bad Liar: She's simply terrible at telling lies since her reactions make it obvious she's being dishonest.
  • Battle Couple: With Soushi.
  • Because You Were Nice to Me: She falls in love with Soushi because he's the first person to show genuine interest in her and care deeply about her feelings, instead of approaching her because of her family or social status.
  • Bitch Alert: In-universe whenever Ririchiyo meets someone new.
  • Blonde, Brunette, Redhead: The brunette to blonde Nobara and redhead Karuta.
  • Bokukko: She refers to herself with the masculine pronoun "boku", which is quite odd coming from a refined Ojou.
  • Broken Bird: She prefers to be left alone because she's afraid of being hurt by others or hurting them to protect herself like it has happened in the past. She later starts healing thanks to Soushi and her new friends.
  • Bully Magnet: When she was in elementary school, other kids bullied her for being rich and "boring". The teacher did intervene, but he was only seeking to gain the favor of the Shirakiin family. These unpleasant experiences were the cause of Ririchiyo's "bad habit" of talking down to people.
  • Character Development: Ririchiyo is finally able to smile sincerely at Soushi by the end of the anime.
  • Childhood Friends: She and Renshou grew up in the same neighborhood. Ririchiyo denies they're friends, but it's obvious they're quite close.
  • Cry Cute
  • Curtains Match the Windows: Different shades, but both her eyes and hair are colored purple.
  • Dark and Troubled Past: She grew up in an isolated, unloving environment and the people she interacted with either bullied her or pretended to be nice because of her family connections.
  • Defrosting Ice Queen: Played with. Ririchiyo may appear a typical cold and mean Ice Queen at first glance, but it's soon made clear that's not the case. She's just a socially awkward girl who prefers to be left alone because her Stepford Snarker tendencies drive people away. Thanks to her love interest and her friends, Ririchiyo's social skills improve and she starts opening up to others.
  • "Do It Yourself" Theme Tune: "Kimi wa (You are)", ending theme for Episode 3.
  • Don't Call Me "Sir": After becoming a couple in the reset timelime, Ririchiyo has to remind Soushi to use the honorific "-san" instead of "-sama" when he calls her by name.
  • Even the Girls Want Her: Nobara even stated to Ririchiyo that she would like a sexual kind of friendship with her...when they first met.
  • Flower in Her Hair: In her youkai form, she wears a flower on one of her horns.
  • Friendless Background: She didn't have any friends until she moved to Maison de Ayakashi, which gave her her No Social Skills problem.
  • Glowing Eyes of Doom: Her eyes glow when she uses her Oni blood.
  • Godiva Hair: Her long hair covers any naughty bits during her Shower Scene.
  • Heal the Cutie: She had a very lonely childhood where she was isolated from everyone in her household, other kids bullied her, and people who were nice to her were more interested in her rich family than in her. This all made Ririchiyo into a Broken Bird who hides behind a snobby mask out of habit of pushing people away. She had moved to Maison de Ayakashi to live alone and stay away from people to keep herself from offending anyone, but she ends up finding a man who deeply loves her and new friends who aren't put off by her sharp tongue. Soon, Ririchiyo grows out of her loneliness and becomes more emotionally open as she now has people who truly care about her instead of her family name.
  • Heroic Self-Deprecation: She constantly brings herself down for not being able to control her sharp tongue, which causes her to lash out at those around her.
  • Hidden Heart of Gold: Ririchiyo is good-natured, considerate and very sensitive, but hides it behind a Rich Bitch act as a way to protect herself. Problem is she got so used to it that now Ririchiyo doesn't know when to quit it and often says insulting things she doesn't really mean. She eventually does learn to abandon the facade.
  • Hime Cut: Befitting her status as an Ojou, Ririchiyo has straight-cut bangs, hip-length sidelocks, and classic length straight hair. This is one of the many things Nobara finds adorable about her when they first meet.
  • Horned Humanoid: Her youkai form has two curved horns.
  • Huge Guy, Tiny Girl: Tiny Girl to Soushi's Huge Guy.
  • Inferiority Superiority Complex: She acts haughty and condescending in order to hide her insecurities, self-loathing and fears. Unusually, she's well aware of it and is one of the things she wants to change about herself.
  • Lady and Knight: She's the lady, Soushi is her knight.
  • Light Feminine and Dark Feminine: The dark to Karuta's light.
  • Like Brother and Sister: She has known Renshou since childhood and their relationship is similar to that of a grumpy sister and her laid-back brother.
  • Little Miss Badass: She's very short, but she can put up a good fight thanks to her Oni heritage.
  • Little Miss Snarker: She's a short and petite girl, but once she opens her mouth you'll be surprised by the sharp tongue she has. It's, however, deconstructed because this is a result of her lack of social skills and Ririchiyo actually wishes to grow out of her snarky tendencies.
  • Living Emotional Crutch: She's Soushi's entire reason for living. It's thanks to her that he developed his own personality and emotions.
  • Lonely Rich Kid: As the atavist of the family, Ririchiyo was treated as a family treasure, but she was virtually casted away from anyone in the household. At school, she was bullied by her peers and the teachers came to her aid just to give a good impression to her family.
  • Loner-Turned-Friend: When she arrives at Maison de Ayakashi, she's a loner seeking to get away from people so she doesn't have to hurt them. As she interacts with the other residents, Ririchiyo gets over her fear of getting close to others and opens up to her new friends.
  • Loony Friends Improve Your Personality: Becoming friends with the colorful people of Maison de Ayakashi helps Ririchiyo open up and improve her social skills.
  • Love Epiphany: While she was already attracted to him, Ririchiyo fully realizes her feelings for Soushi after she finds out he was her childhood Pen Pal.
  • Meaningful Name: Her family name can be translated as "White Oni House". Her first name can mean "Cold/Lonely Butterfly".
  • Meganekko: She wears glasses sometimes.
  • Minor Living Alone: She's only fifteen years old, but she came to Maison de Ayakashi to live alone so she could get over her No Social Skills problem.
  • Mistress and Servant Boy: She's the rich mistress and Soushi is her devoted servant. However, unlike most examples, Ririchiyo doesn't abuse or boss Soushi around and is actually unnerved by his lack of self-regard. Once they start a romantic relationship, she tries to get Soushi to drop the servant mentality and act as her equal.
  • Morality Pet: Ririchiyo is the only person Soushi truly cares about and the one he would never exploit for his own benefit.
  • Naginatas Are Feminine: She's the only main female character to use a weapon, which happens to be a naginata.
  • No Social Skills: A big issue for her. Since she has pushed people away in fear of being hurt her entire life, now she has no idea how to interact with people without insulting them.
  • Official Couple: With Soushi. They start dating near the end of the first part of the story. Things don't go smoothly for their reincarnations in the second part, though. However, Ririchiyo and Soushi do manage to become a happy couple in the new timeline.
  • Ojou: She's the daughter of a very rich and influential family.
  • Older Than She Looks: She's fifteen, but looks about twelve. Nobara likes this about her.
  • Oni: She's descended from an oni. Interestingly, Ririchiyo's oni horns look like goat horns instead of the standard smooth forehead ones.
  • The Perfectionist: Whenever she cooks, she's meticulously careful to get every single detail right.
  • Power Dyes Your Hair: Her hair color becomes lighter in her youkai form.
  • Protectorate: Soushi's goal in life is to protect Ririchiyo.
  • Rapunzel Hair: Her hair reaches down to her hips.
  • Raven Hair, Ivory Skin: A very pretty young girl with long black hair and pale skin. Nobara notes this as one of her attractive features.
  • Romantic Two-Girl Friendship: With Karuta.
  • Scarf of Asskicking: The costume of her youkai form includes a very long scarf.
  • Secret Secret-Keeper: Ririchiyo reveals that she had long figured out that Kagerou wasn't the one replying her letters because it was too obvious someone like him would never write letters like that. This makes Soushi feel overjoyed at knowing that Ririchiyo was always able to notice him.
  • Shana Clone: A different take on the archetype. She's a rich, childlike fifteen-year-old Tsundere with black Rapunzel Hair and Grade A Zettai Ryouiki. Unusually, she dislikes her common approach to people and is trying her best to improve her social interactions. Also, her love interest, who specifically asks her to call him a dog and treat him like one, is such an Extreme Doormat she actually finds it very difficult to do so.
  • She's Got Legs: Nobara sees her long legs as her major Charm Point.
  • Single Woman Seeks Good Man: She falls in love with Soushi because he was the first one to be interested in her as a person and he repeatedly shows his deep love and devotion to her.
  • Sour Outside, Sad Inside: Described as such by Nobara; Ririchiyo acts mean and haughty and then walks away to sulk somewhere. This is because a very isolated family environment and bullying left her with emotional baggage and virtually No Social Skills, something Ririchiyo hates herself for.
  • Stepford Snarker: She gained a "bad habit" of talking down to people as a way to cope with a lonely family environment and bullying. She's gradually growing out of this.
  • Supernatural Is Purple: Her purple eyes are a hint of her half-oni nature.
  • The Three Faces of Eve: The Wife (the mentally older and sensible girl of the 3 main female characters).
  • Token Mini-Moe: Ririchiyo is the smallest resident of Maison de Ayakashi, being only 145 cm (or 4'9") tall.
  • Tsundere: An interesting variation, along with deconstructed. Ririchiyo says she picked up a bad habit of putting up an arrogant front and talking down to others as a coping mechanism for the bullying she suffered in the past. She actually feels bad about lashing out at others all the time and tries her best to grow out of it. She also treats her love interest quite nicely even though he explicitly wouldn't mind to be mistreated by her.
  • Tsurime Eyes: She has the sharp eyes typically found in Tsunderes like her.
  • The Un-Favourite: An interesting case of this. Due to her strong youkai blood, Ririchiyo was treated as a family treasure back at home, while her sister was largely ignored by the rest of the household. To compensate, her parents showered her younger sister with love while rejecting Ririchiyo, believing that she didn't need them anyway.
  • Unlimited Wardrobe: Outside of her school uniform, you probably won't see Ririchiyo in the same outfit twice.
  • Uptown Girl: Played with. The Miketsukami family is just as prosperous as the Shirakiin, however because of his kitsune blood, Soushi was raised as a prisoner instead of a family member. Throughout his life, Soushi was forced to worm his way to freedom by becoming the servant of people in higher positions than him. While serving Kagerou, he fell in love with Ririchiyo as he replied her letters. He could tell that she was from a very different world than him, so he thought becoming her servant was the best he could do.
  • What Is This Thing You Call "Love"?: She has troubles understanding her feelings for Soushi given her No Social Skills, even assuming her racing heartbeat is a symptom of illness. She eventually gets it right and starts dating Soushi.
  • Zettai Ryouiki: Many of her outfits include thigh-high stockings.

Tropes that apply to the second half of the series

At the end of Part I, Ririchiyo was killed at the age of 16 after trying to stop the enemy youkai raid after they killed Soushi. In Part II, she is reincarnated, but has amnesia from the trauma of losing Soushi after he protected her. Once she does remember, she gains a resolution to protect everyone so that history does not repeat itself.

  • Angst Coma: She enters a coma after Kagerou forces her to face the fact that the previous Soushi is dead.
  • Broken Bird: She has trust issues due to a lot of people having pretended to like her for being the daughter of the Shirakiin family. Remembering how Soushi died protecting her in her past life only adds to her emotional baggage.
  • Declaration of Protection: She swears to protect Soushi and all her friends to not let them die in the Hyakkiyakou again.
  • Friendless Background: Much like her previous incarnation, however, this time it isn't because of bullying, but because her classmates would pretend to be nice to her in fear of how her family would retaliate should they ever say or do anything that would anger her.
  • Hime Cut: Not unlike her past life, this Ririchiyo has the straight-cut hairstyle expected from an Ojou, although she has cheek-length sidelocks instead of her previous self's longer ones.
  • I'm Crying, but I Don't Know Why: This happens when she first meets Soushi's reincarnation, triggering Ririchiyo's repressed Past-Life Memories.
  • Loving a Shadow: She sees past Soushi reflected in his reincarnation, subconsciously using him as a Replacement Goldfish for his own past self because he's allowing her to. Kagerou is the one who forces her to face that she's only loving a ghost portrayed by someone else. Ririchiyo then distances herself from Reincarnated!Soushi when she decides to try and think of him as a different person.
  • The Mourning After: After accepting that the Soushi she fell in love with is dead, Ririchiyo can't bring herself to love anyone else, not even Soushi's very reincarnation.
  • My Greatest Second Chance: After recovering her past memories, Ririchiyo gains a resolution to not let Soushi or any of her friends die this time around.
  • Not Allowed to Grow Up: Of all of the characters, Ririchiyo's reincarnation is the only one who is the exact same age 23 years later.
  • Taking the Bullet: In Chapter 34, she takes an attack from a berserk Kuroe to protect Soushi.
  • Tearful Smile: When finally accepting the fact that Soushi is dead.
  • Trauma-Induced Amnesia: She can't remember her past life at first due to the trauma of losing Soushi.

    Soushi Miketsukami
Voiced by: Yuuichi Nakamura, Miyuki Sawashiro (child & female forms) (Japanese), Chris Patton (English)

The assigned SS Agent to Ririchiyo and her servant, Soushi is a half-kitsune whom Ririchiyo helped when she was little. Very calm, polite, and gentle to people, he holds a deep devotion towards his master, blindly obeying her and protecting her with his life if the situation calls for it.

  • Accidental Pervert: In Chapter 37, he enters Ririchiyo's apartment without permission out of concern that she hasn't eaten anything out of the shock from the discovery of letters from the future. When he opens the doors, he walks in on Ririchiyo wearing nothing but a Modesty Towel.
  • All of the Other Reindeer: His family had him locked up in a warehouse his entire life because of his kitsune blood. They only let him get out when he let the women in the family use him as a servant/boy toy.
  • Always Save the Girl: Soushi cares more about Ririchiyo than anything else.
  • Animal Motifs: He's literally part-fox demon, so there's that, but as the title of the series suggests he's also frequently compared to a dog due to his extreme Undying Loyalty to Ririchiyo. When he's in his demon form, he'll even wag his tails when he's happy.
  • Anti-Hero
  • Babies Ever After: In the final chapter, Zange has a vision that shows Soushi's dream of having a family with Ririchiyo will come true. Moreover, it's implied their son will be Reincarnated Soushi which really brings out some awkward implications...
  • Badass in a Nice Suit
  • Battle Butler: Even amongst an army of them in the form of the SS Agents, he stands out in his Undying Loyalty to Ririchiyo.
  • Battle Couple: With Ririchiyo.
  • Becoming the Mask: Not entirely, but pretty damn close. Soushi wrote to Ririchiyo under the guise of an idealized version of Kagerou that he made up in his head, because he felt it was his job to make her like her fiance. He eventually realized that in the course of his correspondence that he not only got lost in the role, but also that he'd begun to feel genuine emotion.
  • Bishie Sparkle: He's literally surrounded by sparkles whenever he gets in The Charmer mode.
  • Bishōnen
  • Bodyguard Crush: He's Ririchiyo's SS Agent and he isn't shy to admit he asked for the job specifically to be by her side and protect her.
  • Broken Ace: Soushi is good at virtually everything, but his upbringing and subsequent plots to escape his family caused him to develop the personality of someone who will do anything to get what he wants.
  • The Champion: Soushi has decided to devote his life to Ririchiyo and there's nothing he wouldn't do for her.
  • The Charmer: Wooing people is chief among his many talents.
  • Chick Magnet: He attracts the attention of females very easily. It doesn't help that he takes ass-kissing Up to Eleven.
  • Childhood Friends: Knew Zange, Kagerou, and Watanuki from the age of 14 on. It's hard to say if they really are friends, though.
  • Covert Pervert: Behind his polite, humble and charming front, Soushi is one of the biggest perverts around. His Stalker with a Crush tendencies are just the beginning of it.
  • Crazy Jealous Guy: A calm variant.
  • Cultured Badass: Subverted, as the only reason he's so well-learned is because he didn't want to "disappoint Ririchiyo with his simpleness."
  • Dark and Troubled Past: His family raised him under house arrest from birth, and when it became too much, he learned to appeal to the sympathies of household workers and members in order to manipulate his way to freedom. He eventually ended up in the service of Kagerou and his family until he turned 20, at which point he was freed.
  • Declaration of Protection: He declares he exists for the sake of protecting Ririchiyo.
  • Devoted to You: Soushi frequently says he lives for the sake of serving and protecting Ririchiyo and just being by her side is like a dream come true for him.
  • Dissonant Serenity: He keeps his polite and calm behaviour no matter the circumstances. Connected with his twisted personality.
  • Dogged Nice Guy: To Ririchiyo. The dogged is kind of a pun.
  • "Do It Yourself" Theme Tune: "Rakuen no Photograph (Paradise of Photographs)", ending theme for Episode 3.
  • Duality Motif: His right eye is blue, while the other is golden yellow. This is probably to indicate the fact that he is a half-kitsune.
  • Empty Shell: In his backstory, the only thing Soushi cared about was becoming free from his family by any means necessary and he always adjusted his behaviour to how it would be easier to manipulate people at the moment. This made him into nothing but a Professional Butt-Kisser with no self-regard whatsoever. Kagerou outright called him boring because of this. It wasn't until he came into contact with Ririchiyo that he began to develop into his own person.
  • Extreme Doormat: He became a Professional Butt-Kisser in order to appeal to his higher ups and worm his way to freedom from a life-long house arrest. His previous master Kagerou noted that he'd willingly do an embarrassing act with a smile on his face. He's something of a subversion since he uses this tactic to achieve his own ends, but it's also true he assigns so little value to his life that he'd even commit suicide if that was what was wished of him.
  • Flower Motifs: In his introduction, the window is open and Cherry Blossoms drift inside the hall around him. They also appear in his transformation scenes.
  • Gold Digger: A... somewhat more sympathetic one before he became Kagerou's servant and met Ririchiyo. To free himself from his house arrest, Soushi seduced many women of higher positions in his household and made himself into their boy toy so it gradually became easier for him to move around. It stopped when he found Kagerou's mother and got to convince her to release him from the Miketsukami family.
  • Guile Hero: More than willing to manipulate anyone into getting what he wants, including the mistresses and masters that he works under, putting himself in as much control as he can with his relationships.
  • Happiness in Slavery: Soushi makes no secret of how much he loves to be his beloved Ririchiyo's servant. He actually would love that she treated him like a dog instead of a person.
  • Heroic Sacrifice: He dies protecting Ririchiyo from Inugami at the end of Part I.
  • Heroic Self-Deprecation: Frequently refers to himself as a "lowly servant" or a "dog unworthy of anything", even for something as simple as a "thank-you". Usually Played for Laughs. To a certain extent, he uses this as to manipulate others and/or to gain control of a situation, but he really, truly is not proud of the way he is, and does not see much value in himself at all.
  • He Will Not Cry, So I Cry for Him: He cries on Ririchiyo's behalf upon listening to her speak about the loneliness she's felt through her life.
  • Huge Guy, Tiny Girl: Huge Guy to Ririchiyo's Tiny Girl. She only comes up to the middle of his chest.
  • I Just Want to Be Free: When he was young, his family kept him under home arrest since birth. Soushi wanted nothing more than be free from his prison and go to the outside world. He used all the means necessary to worm his way to freedom. However, as Soushi started to gain his own sense of self thanks to Ririchiyo, he realized that even though he wished to become free his entire life, he never really thought about what he wanted to do with that freedom. He then decided the only thing he wanted was to be by Ririchiyo's side.
  • I Just Want to Be Loved: He's told Ririchiyo his greatest dream is to have a child with her someday. Considering his terrible childhood, this is likely so that he can give someone a better life than the one he had, and also because a loving family was something he'd never had.
  • I Love You Because I Can't Control You: He'd grown fond of Ririchiyo through the letters they exchanged, but his devotion to Ririchiyo was sealed when he realized that the entire time she'd been aware he'd been distant in his writings, and that when he for the first time ever was genuine in a letter, it didn't escape her notice.
  • Insecure Love Interest: As much of a stalker as he is, Soushi honestly doesn't believe he's worthy of Ririchiyo. To him, being her servant is the best he can hope for. Even after becoming a couple, Ririchiyo has trouble getting Soushi to think of himself as her equal.
  • I Owe You My Life: To Ririchiyo. It wasn't until after getting to know her through her letters that he began to develop into his own person.
  • I Want My Beloved to Be Happy: He might a yandere stalker, but to his credit, he's not willing to make assumptions about his relationship with Ririchiyo, and lets her be the one to decide where they stand with each other. When he says he'd do anything for her, he really does mean it.
  • Katanas Are Just Better: He wields a katana in his youkai form.
  • Keigo: Speaks very respectfully under any and all circumstances.
  • Kitsune: He has kitsune blood which gives him transformation powers and possibly influences his manipulative nature.
  • Lady and Knight: He's the knight, Ririchiyo is the lady.
  • Ladykiller in Love: Soushi was with many women in his past, but he was merely using them as a means to get his freedom. It was when he got to know Ririchiyo that Soushi fell in love for real and he has been devoted to her ever since.
  • Love Before First Sight: Kagerou made him write replies to the letters from Ririchiyo. Soushi got to know her rather well throughout her letters and eventually developed genuine feelings for her even though he had never met her before.
  • Loving Details: There doesn't seem to be one thing that Soushi doesn't know about Ririchiyo. In Episode 9, he gives a laundry list of Ririchiyo's likes, dislikes, hobbies and daily routine... When all Zange asked was if Ririchiyo liked dogs or cats better.
  • Manipulative Bastard: He got his way through life by stealthily exploiting other people, even his friends, which he's still all too willing to do even now. The only person he will not exploit is Ririchiyo.
  • Meaningful Name: Miketsukami means "Great Fox God".
  • Megane: Sometimes. The only times he's really seen wearing glasses is when he's relaxing.
  • Me's a Crowd: He's been seen using his duplication abilities to help with chores or as part of battle strategy.
  • Mistress and Servant Boy: He willingly chose to be Ririchiyo's "dog", and is quite an eager one at that. It gets Played With because Ririchiyo never acts as his superior and is actually disturbed by his submissiveness and excessive devotion. Once they start a romantic relationship, Ririchiyo tries to get Soushi to act more like a boyfriend instead of a servant, but it's hard for him.
  • Mystical White Hair: Silver-tinged, but close enough. It actually does turns white when he's in his demon form in the anime though.
  • No Social Skills: Soushi admits he doesn't really know how to interact with other people other than acting like a servant, since that was the only mean of contact with others he had for most of his life.
  • Not with Them for the Money: From the very beginning, Soushi makes it clear to Ririchiyo that his devotion to her has nothing to do with her family status. It's later revealed that Ririchiyo was, in fact, the first woman Soushi became interested in because of her personality instead of a social position he could exploit.
  • Official Couple: With Ririchiyo. They start dating near the end of the first part of the story. Their relationship enters shaky grounds in the second part now that they've been reincarnated, and Ririchiyo's declared that she only loves his past self. However, things turn out well in the third part and Soushi and Ririchiyo are now a happy couple in the new timeline.
  • Off with His Head!: Inugami kills him by cutting off his head at the end of Part I.
  • Playing Cyrano: While working under Kagerou, Soushi was made write letters for Ririchiyo in his master's place because Kagerou didn't want to do it himself. Instead of responding the letters like Kagerou would, Soushi wrote them in a way that he would make Ririchiyo like Kagerou because he felt that was part of his job. As they exchanged letters through several years, Soushi ended up falling in love with Ririchiyo, but he was saddened by the thought that the one she was interested in was Kagerou, not him. However, Ririchiyo reveals she always knew Kagerou wasn't the one replying her letters, which makes Soushi feel overjoyed at Ririchiyo being able to notice him right from the start.
  • Poisonous Friend: He is astoundingly loyal to Ririchiyo, but has no qualms about hurting others if they're in his way, not even his own friends.
  • Power Dyes Your Hair: His hair color becomes white in his youkai form.
  • Pragmatic Hero
  • Professional Butt-Kisser: Before he met Ririchiyo, Soushi lived by appealing to people in higher positions than him and doing whatever they wanted so he could use them to become free.
  • Property of Love: Soushi happily says all the time that Ririchiyo is his owner, referring to himself as her dog.
  • Sarcasm-Blind: Despite the fact that one of Ririchiyo's defining characteristics is that she often says the exact opposite of what she means, Soushi tends to take the things she says way too seriously.
  • Satellite Love Interest: A rare main protagonist example. He has little to no personality outside of his devotion to Ririchiyo. He even declares he would have no reason to live if he can't serve her. Justified since he basically was an Empty Shell before he met Ririchiyo.
  • Self-Duplication: Has the ability to form clones of himself.
  • Sex Shifter: His shapeshifting allow him to transform into a woman.
  • Sexual Extortion: It's heavily implied (and made clear in the anime) that one of the things Soushi did to worm his way to freedom from his life-long house arrest was allow the women in higher positions of his extended family use him for sexual favors. Disturbingly, he started doing this in his early teens.
  • Sharp-Dressed Man
  • Single-Target Sexuality: Ririchiyo-sexual. He himself has stated that it wouldn't matter if she were an old woman, a boy, or even an animal, he'd still be equally attracted to her.
  • Stalker Shrine: He has a photo-covered shrine to Ririchiyo in his apartment room.
  • Stalker with a Crush: People are quick to notice Soushi's obsession with Ririchiyo and the way he's always following her around make him a prime stalker. Soushi prefers to call himself her dog, though. He even comes with a Stalker Shrine!
  • Stepford Smiler: Since he was very young, Soushi had to put up an obedient servant boy act as a means to gain his freedom. Behind his polite smile, he was completely hollow inside. It was thanks to Ririchiyo that he realized this and gained his own personality. Even then, he only can smile sincerely when he's with Ririchiyo.
  • Subordinate Excuse: He wanted to become Ririchiyo's servant because nothing makes him happier than to serve her.
  • Suicide as Comedy: Soushi's attempts to convince Ririchiyo to commit his Seppuku when she claims doesn't need him and wants to dispose of him are Played for Laughs.
  • Superpower Lottery: Soushi gets shapeshifting, shadow clones, super reflexes, super strength, and a Cool Sword, which is a lot more than most other atavists get.
  • Taking Advantage of Generosity: His strategy to obtain freedom for himself when he was young was to appeal to the sympathies of household workers and members in order to manipulate his way to freedom. Ultimately, this undeniably got engrained into his personality.
  • Tranquil Fury: Even when pissed off, he remains polite and respectful at all times.
  • Undying Loyalty: To Ririchiyo.
  • Voluntary Shapeshifting: The signature power of Kitsune like himself. He can even turn into a girl!
  • White Hair, Black Heart: Though there does exist goodness in him, his (self-admitted, even) twisted and manipulative personality qualifies him for this trope.
  • A Wolf in Sheep's Clothing: According to Kagerou, who isn't far from the truth. Soushi plays up his charm and submissiveness to get people's sympathy and hide his more twisted, manipulative nature. He's not a bad person deep down, though.
  • Yandere: Oh definitely. He's arguably got more self control than most examples, but his obsession with Ririchiyo and desire to protect her can go to very extreme and disproportionate levels very fast. Renshou even calls him this once.

Tropes that apply to the second half of the series

Soushi was killed in action at the end of Part I at age 23, protecting Ririchiyo from a band of evil youkai. His reincarnation appears in Part II. This Soushi has no memories of his past life, which troubles his relationship with Ririchiyo. He tries very hard to act like the previous Soushi to gain Ririchiyo's love, but things just don't seem to be working out between them.

  • Amnesiac Lover: In Part II, reincarnated Soushi doesn't remember anything of his past life or his past relationship with Ririchiyo. Ironically, he's the one pining after Ririchiyo because she's still in love with his old self.
  • Attractive Bent-Gender: When visiting Ririchiyo during gym class one day, he transformed into a girl because he hoped that Ririchiyo would be more comfortable with the company of a female. Naturally, all of the guys in her class are interested.
  • Becoming the Mask: Initially, he was just trying to emulate his past self to express his gratitude to Ririchiyo for saving him. After spending time with Ririchiyo, his behaviour soon stopped being an act as his feelings for her grew stronger.
  • Dark and Troubled Past: He had it even worse than the previous Soushi since his family put him under even worse restrictions than before. However, thanks to Ririchiyo setting up precautions, he didn't have to go to the lengths he did in his previous life to escape it.
  • Doppelgänger Replacement Love Interest: He is Soushi's reincarnation, but he lacks his past self's memories and this makes him essentially a different person. Even then, this Soushi loves Ririchiyo's reincarnation and wants to replace his past self for her sake. Unfortunately for him, it doesn't work out because Ririchiyo decides the previous Soushi is the only one she loves. It's until Chapter 34 that Ririchiyo realizes that no matter if he's a reincarnation, Soushi is still Soushi and she admits she could have loved him the same as his past self had they gotten more time together before the time reset.
  • Evil Costume Switch: He wears a black outfit in his youkai form as opposed to his original white one. Subverted when it's revealed he's not actually evil.
  • Generation Xerox: All the Atavist's reincarnations retain most of their former characteristics, but Soushi's notable for almost flawlessly emulating his past self, despite the fact he, unlike most of the others, does not have his Past-Life Memories.
  • Hopeless Suitor: It eventually becomes clear that no matter what he does, Ririchiyo will never love reincarnated Soushi in the same way she loved his previous self. However, Ririchiyo admits that she might have given him a chance if they had spent more time together before the timeline got reset.
  • I Hate Past Me: Reincarnated Soushi hates his past incarnation for leading an immoral lifestyle to gain his freedom and winning over Ririchiyo.
  • I Owe You My Life: Before she died, Ririchiyo asked Kagerou's mother to release Soushi from his house arrest once he reincarnated. This is the reason why reincarnated Soushi decided to repay her by trying to replace the previous Soushi.
  • Last-Name Basis: This Soushi calls Ririchiyo by her last name, one of the first things Ririchiyo notes is off about him.
  • Love Before First Sight: Even though he lacks the previous Soushi's memories, he subconsciously kept yearning for Ririchiyo and thought of her whenever he saw women with long black hair. When he met Ririchiyo's reincarnation, his feelings just grew stronger and it didn't take long for him to fall for her as hard as his past incarnation did.
  • Love Hurts: He loves Ririchiyo very much and spending time with her gave him many emotions that he didn't know before. The most prominent one being the pain of knowing he can't take the place of his old self in her heart.
  • Megane: Unlike his previous self, this Soushi wears glasses all the time, except when he is in his youkai form and when trying to emulate past Soushi even more.
  • Oedipus Complex: Reincarnated Soushi is implied to eventually be reborn as Soushi and Ririchiyo's child in the reset timeline, and Zange warns Ririchiyo he'll be quite attached to his mother.
  • Reincarnation Romance: Subverted. Reincarnated Soushi does love reincarnated Ririchiyo, but she rejects him because his past self is the only one she loves.
  • Relationship Reset Button: He doesn't have memories from the past, which, as stated above, throws a monkey wrench into his relationship with Ririchiyo.
  • Replacement Goldfish: He lacks his past life memories, but that doesn't stop him from trying his darnedest to act like, and take the place of, his former self for Ririchiyo's sake. It doesn't turn out well for either of them.
  • The Resenter: He's jealous and resentful of the past!Soushi for getting Ririchiyo's love. Essentially, he's jealous of... himself.
  • What Does She See in Him?: He doesn't understand why Ririchiyo would prefer his past self over him, since his current self has lived a much more decent and "pure" life compared to his previous self who used dirty methods to obtain his freedom.
  • White Hair, Black Heart: Qualifies better than his past self. This Soushi really does not care about anyone but Ririchiyo.

  • Ambiguously Brown

  • Mundane Made Awesome: His demon form is a sentient, flying, roll of cloth.
  • Nice Guy
  • Non-Action Guy: In his defense, it's hard to be a man of action when your true form doesn't even have limbs (save for two little stubs that serve as arms).
  • Younger Than He Looks: Renshou looks way more mature than Ririchiyo or Karuta, but he's only two years older than them and even goes to the same school. This gets lampshaded by Nobara.

Tropes that apply to the second half of the series

Renshou was the only one of the Maison de Ayakashi members who did not die due to the enemy youkai raid at the end of Part I. He was waiting for the others to reincarnate for these past 23 years. He's become quite jaded as a result of living on while the others had to be reborn again.

  • Team Dad: He plays this role to his friends now that he's much older and mature than them. Ririchiyo even calls him out on how he acts like a father.

  • Curtains Match the Windows: In the one color illustration where see him without his mask reveals this.
  • Disposable Fiancé: The fact Kagerou was engaged to Ririchiyo seems to serve no other purpose than being the reason she and Soushi came into contact with each other, since she can't stand him, and he never shows any sort of interest in her that could remotely be considered "romantic" unless it's to get a rise out of either her or Soushi. Not to mention Kagerou didn't waste any time calling Ririchiyo his ex-fiance after she and Soushi got together.
  • "Do It Yourself" Theme Tune: "SM Hantei Forum (S&M Judgment Forum)", ending theme for Episode 5.
  • Domino Mask: He wears a mask over his eyes at all times.
  • Dynamic Entry: Some of his Big Entrance's involve this.
  • Embarrassing Cover-Up: Kagerou's personality would make just about anyone assume he was being a lazy jerk when he told Soushi to write the letters to Ririchiyo. The truth was that he didn't want to write to her with his horrible handwriting.
  • Faking the Dead: In the rebooted timeline, Kagerou fakes his own death to lure Inugami and Shimon into a trap.
  • Fangs Are Evil: His canine teeth are pronounced, which adds to his vampiric appearance. They turn into Cute Little Fangs when he's drawn as a chibi.
  • Four Eyes, Zero Soul: When he was younger, he wore glasses and was every bit as arrogant as he's now.

  • The Illegible: His handwriting is terrible and barely legible. This is why he had Soushi write letters for Ririchiyo instead of doing it himself.

  • Large Ham: His theatrical costume and general over-the-topness speaks by itself.
  • Like Parent Unlike Child: Considering what a decent person his mother is, how the hell he turned out such a loud and egotistical S&M obsessed is anyone's guess.
  • Long-Haired Pretty Boy
  • Lovable Sex Maniac: His vocabulary is littered with references to various sex and fetish plays and the only gifts he ever seems to get anyone are S&M props.

  • Rapunzel Hair: He has waist-length hair.
  • Scary Shiny Glasses: In his younger days.
  • Sir Swears-a-Lot: He constantly refers to people by way of insulting them and he's the most likely to warrant the need for censor bleeps. In the dub they even once chose to have him drop a "fucktard" in lieu of censoring.
  • Smarter Than You Look: Yes, when it comes to trying to compare everything to S&M, he's absolutely ridiculous. But in the moments where you find him seriously analyzing a situation, or a person's character, he can be surprisingly accurate.
  • Supernatural Is Purple: According to a color illustration, he has purple eyes like Ririchiyo, probably due to his Oni heritage.
  • There Are Two Kinds of People in the World: Sadists and Masochists, and nothing else in between. This is even the focus of his ending theme.

  • Walking the Earth: He's rarely at Maison de Ayakashi because he likes to go traveling. At the end of the series, Kagerou decides to go traveling around the world to search for a new destiny now that the Hyakkiyakou has finally ended, taking Zange and Kuroe with him.

  • Older Than He Looks: He's supposed to be 20, but he looks nearly identical to how he did at 14 in his previous life. The fact he's kept a short haircut and isn't as tall as he used to be only adds to it. He claims he'll grow back to his original height later.

  • Babies Ever After: In the final chapter, among Zange's visions of the future we see that Watanuki and Karuta eventually have a child together. It's implied their child is Inugami's reincarnation.
  • Beta Couple: With Karuta.
  • Bishōnen: His human form is just as cute as his youkai form.
  • Brooding Boy, Gentle Girl: Brooding Boy to Karuta's Gentle Girl.
  • Butt-Monkey: Tries to be a bona fide delinquent and earn some respect, but it never works out for him.
  • The Champion: He aspires to become Karuta's protector.
  • Childhood Friend Romance: He has been crushing on Karuta since childhood. The feeling is mutual.
  • Competition Freak: Watanuki reacts this way at any opportunity to beat Soushi at something.
  • Declaration of Protection: He says he will protect Karuta. Not that she needs his protection.
  • Delinquent Hair: He dyes his hair blond because in Japan young delinquents tend to bleach their hair.
  • Distressed Dude
  • "Do It Yourself" Theme Tune: "one way", ending theme for Episode 4 with Zange (or at least he keeps butting in).
  • Don't You Dare Pity Me!: He gets seriously pissed at anyone looking down on his small and weak tanuki form.
  • Dragged into Drag: At the end of Episode 12 by his bullies.
  • Embarrassing Nickname: Natsume calls him Rascal. Watanuki hates it.
  • Fun Size: His tanuki form is a tiny, fluffy little thing. Watanuki, however, hates that everyone looks down on him for being small.
  • Fun T-Shirt
  • Hair-Trigger Temper: Every single thing sets him off.
  • Hates Being Called Cute: He really hates it when others say his tanuki form is cute. This is the source of his rivalry with Soushi; Soushi once called Watanuki's youkai form cute, which Watanuki took as the ultimate insult to his pride.
  • Hilariously Abusive Childhood: The horrible bullying he suffered from Zange and Kagerou throughout their childhood is entirely Played for Laughs.
  • Hot-Blooded
  • I Just Want to Be Badass: He insists on being a delinquent because he wants to be someone strong enough to protect Karuta.
  • I Want to Be a Real Man: His goal is to become a strong and reliable man for Karuta's sake.
  • Japanese Delinquents: Watanuki insists that he is one. No one takes him seriously.
  • Jerk with a Heart of Gold: He's an ill-tempered and loud-mouthed self-proclaimed delinquent, but it's obvious Watanuki is a good-natured, kind guy even if he tries to deny it.
  • Last-Name Basis: Only a handful of people address him by his first name (his butler, Kagerou, Chino, and Mitsuki), but oddly enough, this doesn't include Karuta or Zange, the two people he's closest to (it should also be noted that Watanuki addresses both of them by their first names without honorifics).
  • Leeroy Jenkins
  • Non-Action Guy: As much as he claims to be a delinquent, Watanuki has no fighting abilities and there's nothing his youkai form can do in battle other than look cute.
  • One Head Taller: He's taller than Karuta by a head.
  • Perpetual Frowner
  • Poke the Poodle: His attempts at being a delinquent include eating taiyaki from the head, talking to a guy named Shiroshiku, holding meetings with his "lackeys" (who are just a bunch of old people) and helping with the housework to get the license he needs to ride a bike he stole.
  • Power Incontinence: He doesn't have a very good control over his powers and sometimes spontaneously transforms into his Tanuki form, often in response to an emotional state. He finds this to be mortifying.
  • Punny Name: His family name is Watanuki and he turns into a tiny tanuki.
  • Rebellious Spirit: Subverted. He wants to think he's this due to his insistence at being a delinquent, but he's clearly such a good-hearted and naive boy that he never can bring himself to do anything too out of the norm.
  • Save the Villain: At request of his future reincarnated self, Watanuki wants to save Inugami from his eternal resets. The ending implies Inugami is reincarnated as his and Karuta's child.
  • Self-Duplication: Like Soushi's Kitsune powers, Watanuki's Tanuki blood has given him multiplying powers. He has tried using this as a battle technique with limited success.
  • Sensitive Guy and Manly Man: Manly Man to Zange's Sensitive Guy.
  • Tanuki: He's one, but his youkai form is much harmless and way cuter than the traditional representation. He also barely has any powers or control over them that can make him useful in battle.
  • Tiny Guy, Huge Girl: With Karuta in their youkai forms. He's a small tanuki that looks like a stuffed animal, while she's a giant skeleton.
  • Tsundere: He tries to act like a tough, prideful guy, but he's actually a softie. Karuta can bring out his Dere-Dere without a hitch.
  • Tsurime Eyes
  • Uke: More than one omake insists that any relationship Watanuki gets himself into will result in him being the bottom. Yes, even with Karuta. He strongly objects.
  • Understanding Boyfriend: Near the end of Part I, Karuta is left stuck in her youkai form because of a curse and she asks Watanuki to give up on her. In return, Watanuki tells Karuta he doesn't care what she looks like, he only wants to be there for her.
  • Undying Loyalty:
    • He refuses to abandon Karuta after she's cursed, swearing to be with her no matter what happens.
    • He was apparently one to Zange in one lifetime, sacrificing his happiness to help him.
  • Unknown Rival: To Soushi.
  • Useless Boyfriend: He always says he's going to protect Karuta, but it's difficult when his youkai form is a stuffed animal-like tanuki and Karuta is a giant skeleton. He can give Karuta the best emotional support, though.
  • Voluntary Shapeshifting: Again, much like the Kitsune, the Tanuki is known to have shape-shifting abilities. Watanuki still needs some work on the "voluntary" part, though.
  • With Friends Like These...: Zange claims he, Kagerou and Soushi are all Watanuki's Childhood Friends. Watanuki says they're just his bullies.

Tropes that apply to the second half of the series

Watanuki was killed in the battle between the Maison de Ayakashi and the enemy youkai at age 16. He has been reincarnated in Part II as a middle school student, but has no memories of Part I, much like Ririchiyo and Soushi. His SS is Karuta, and he is now the youngest of all the residents.

  • Adorably Precocious Child: Very much so, and his constant attempts to be treated like an adult just make seem cuter.
  • Adorkable: Even moreso now since he's younger.
  • Amnesiac Lover: Like Soushi, Banri's reincarnated self doesn't remember the past, including his former relationship with Karuta.
  • The Baby of the Bunch: Being the yongest, he often gets babied by the other residents, especially by Karuta, much to his dismay.
  • Befriending the Enemy: He unknowingly does this with Inugami. Not being able to remember anything from his past life, Watanuki approaches Inugami and befriends him. Surprisingly, this manages to make Inugami develop a soft spot for Watanuki and their friendship even made him consider to put a stop to his eternal resets to live a normal life. Inugami then tries to forget about his friendship with Watanuki by going back in time again and erasing the "If World" with it. In the end, Inugami couldn't stop considering Watanuki his friend and this lead to his defeat.
  • Hero-Worshipper: In sharp contrast to their former relationship, Watanuki's reincarnated self greatly admires reincarnated Soushi for his physical abilities.
  • Just a Kid: He's belittled because of being the youngest of the reincarnated cast. He gets really annoyed that Karuta acts like his babysitter.
  • Locked Out of the Loop: He's the only one that never regains his past life's memories.
  • Only Friend: To Inugami. Watanuki was the only one, other than Shimon, to approach Inugami and try to befriend him. While it was unclear how much Inugami actually appreciated him at first, Inugami did enjoy spending time with Watanuki and considered him his closest friend.
  • Marshmallow Hell: From Karuta's reincarnated self.
  • Morality Pet: Reincarnated!Watanuki ends up becoming this for Inugami. After they became friends, Inugami found himself enjoying a world in which the Shimon he loved died and even started considering living a normal life in that world. Inugami then tried to get rid of those feelings by resetting everything all over again, but he realized even then he still considered Watanuki his friend and this ultimately lead to his defeat.
  • Precocious Crush: Reincarnated!Watanuki is at least six years younger than the reincarnation of Karuta. Watanuki is annoyed that his crush is now not only much older than him, but she's technically his babysitter.
  • Reincarnation Romance: He has a crush on Karuta's reincarnation, despite not remembering their relationship in their past lives.
  • Spanner in the Works: It's his random friendship with Inugami that ends up ending Inugami's resets.
  • Tagalong Kid: Not so much a child, but his reincarnated self is a junior high school boy, making him the youngest of the reincarnated cast and at least six years younger than the reincarnation of his crush, Karuta, who is now his agent.
  • Vitriolic Best Buds: He unexpectedly made friends with Inugami, with their relationship mostly consisting of his friend bossing him around him and Watanuki calling him a slave driver in return.
  • Token Mini-Moe: At 13, he is now the youngest resident in the mansion.

    Zange Natsume
Voiced by: Mamoru Miyano (Japanese), Blake Shepard (English)

The assigned SS agent to Banri, Zange is a half-human, half-hundred-eyed monster who wears a set of black rabbit ears on his head. He is a very cheerful and eccentric individual. He's best friends with Kagerou. He also has a fondness for Soushi and has a tendency to flirt with him and call him "Sou-tan" because of this, though he has given pet names to most of the other characters as well. His youkai blood gives him the power of limited omniscience, and he has a penchant for meddling in the lives of his peers, usually with positive ulterior motives.

  • Agent Peacock: He's quite the fabulous chap.
  • Alone Among the Couples: By the final chapter, Zange is the only member of the main cast without an official or potential romantic partner.
  • Ambiguously Gay: Zange shamelessly hits on Soushi and openly states he'd like to sleep with him. However, it seems like it's more a part of his goofy facade than an actual crush, given that he doesn't show any kind of problem with Soushi being with Ririchiyo and is actually very happy for them.
  • Animal-Eared Headband: Of the bunny variety.
  • The Anti-Nihilist: Zange shows shades of this. He seems to believe things won't end well for him and the other atavists no matter what he does, but Zange still insists on enjoying his life and making his friends happy as long as he can.
  • Bandage Babe: He wears bandages to cover his right eye.
  • Beware the Silly Ones
  • Bishounen
  • Blindfolded Vision: Half-blindfolded.
  • Blood from the Mouth: It was just ketchup though. Or was it?
  • Broken Bird: He reveals that he more or less remembers everything in his past lives, and observes that destiny repeats with all of the atavists coming to the same tragic ends over and over again, implying that he tried but failed to make things better. This resulted in his Stepford Smiler personality and his philosophy that the other atavists should just enjoy life while they can.
  • Bunny-Ears Lawyer: While all SS Agents are this to some extent, Zange takes it literally.
  • Cast From Hitpoints: He collapses whenever he uses his full power because it takes such a huge toll on his body.
  • Catchphrase: "Can't we all just get along?"
  • Chivalrous Pervert: Has elements of one. He's a genuinely a caring and friendly guy and not much of a skirt-chaser, but he seems to like showing off the fact that with his powers he can see, and describe in detail, what kind of underwear Ririchiyo's wearing on a given day.
  • Cool Big Bro: Self-described this in his introduction chapter. Quirkiness aside, he's actually pretty effective. He switches between this and Team Mom to the group.
  • Curtains Match the Window: Red hair and eyes.
  • Dark and Troubled Past
  • Definitely Just a Cold: He plays off his fainting as simply anemia. It's actually his Cast From Hitpoints ability.
  • "Do It Yourself" Theme Tune: "one way", ending theme for Episode 4 with Banri (or at least the latter keeps butting in)
  • Drama Queen
  • Expy: His eyes that are usually shut, trickster personality, innate ability to know more than he lets on, and habit of teasing that he has some sort of secret, make him seem like a more flamboyant but unequivocally good version of Xellos from Slayers.
  • Extra Eyes: His youkai blood gives him these, which he can use to search for information.
  • Eyes Always Shut: Unless he's being serious and/or using his power.
  • Eyes Do Not Belong There: His entire body is covered in eyes, presumably a hundred of them, considering that his ancestry is that of a Hyakume, or Hundred-Eyes monster. Understandably, they're usually covered up under layers of clothes.
  • Fainting Seer: His clairvoyant powers cause him to faint when he uses them too much.
  • Finger Wag
  • For Happiness: Much of his character is built upon doing all sorts of things to ensure the happiness of his friends. He doesn't seem to care much about himself, though. His "Do It Yourself" Theme Tune even has lyrics that reflect this attitude, in this case specifically for Watanuki.
  • Fun Personified: He likes playing pranks or making people laugh, and he often gathers everyone to participate in games and activities together. He's also one of the only characters who genuinely enjoys Kagerou's crazy hijinks. Okay, so he's a Stepford Smiler, but he should really get points for trying.
  • Hidden Heart of Gold: On the surface, he gives the impression of being a shifty character (and that he enjoys being seen as such). He also tends to do things at the expense of the comfort of his friends. But the reality is he's a really nice guy, and more often than not, what he does is for their benefit in the long run. Kagerou calls him out on it.
  • Ill Boy: He doesn't have the healthiest disposition. Apparently it's connected to his power.
  • In Touch with His Feminine Side
  • I Want My Beloved to Be Happy: A non-romantic version. Watanuki once dedicated one life to becoming a doctor and save Zange from his illness, going as far as to neglect his friends and love interest to search for a treatment. After that, Zange wants Watanuki to be happy, regardless of the price to himself. In his ending "one way", Zange is singing about Watanuki and how he should forget about him and live for himself.
  • Keet
  • Laugh Themselves Sick: His reaction to Watanuki comparing Karuta to Tarzan. In general he has a habit of laughing somewhat inappropriately at his friends, though not maliciously.
  • Long-Haired Pretty Boy
  • Manic Pixie Dream Guy: He's a little like one to everyone in how he tries to encourage interactions, but Watanuki and Ririchiyo in particular.
  • Motherly Side Plait: His default hairstyle could be considered this, and to a certain extent he fills in the role as the Team Mom.
  • Mr. Exposition: His powers probably have something to do with it.
  • The Nicknamer: Chiyo-tan for Ririchiyo, Sou-tan for Soushi, Kage-tan for Kagerou, Ren-Ren for Renshou and Rascal for Watanuki.
  • Non-Action Guy: His powers are definitely useful, but since their primary use is for information gathering and they've proven to put a strain on his health in the process, you have to wonder how he ended up with a job that's supposed to involve being a bodyguard.
  • No Sense of Personal Space: He isn't afraid of getting into Soushi's personal space or feeling him up, though Soushi never objects to it.
  • Not So Omniscient After All
  • Obfuscating Disability: His covered up right eye works perfectly fine. He keeps it hidden for Power Limiter purposes.
  • Past-Life Memories: All the atavists are reincarnations and supposedly can remember their previous lives to some extent, but Zange appears to be able to always remember his past lives much more clearly than others.
  • Peek-a-Bangs: His hair covers his patched right eye.
  • Perpetual Smiler
  • The Pollyanna: When introducing himself to Ririchiyo, Zange says some pretty disturbing things about his past with a grin and falsetto.
  • Power Limiter: His eye bandages serve to limit his youkai power.
  • The Prankster
  • Quizzical Tilt: Does this often, but mostly to tease the others.
  • Red Eyes, Take Warning
  • Repetitive Name: Zange and Natsume mean the same thing (summer) in Japanese.
  • Seer
  • Sensitive Guy and Manly Man: Sensitive Guy to Watanuki's Manly Man.
  • Sharp-Dressed Man: If you ignore the bunny ears.
  • Shipper on Deck: Ships Watanuki/Karuta, if the amount of times his meddling is to get them to have time alone together is any indication. He also seems to support Ririchiyo and Soushi.
  • Stepford Smiler: Is one in general, due to him having to deal with the fact he's got the memories of all his past lives and the horrors and/or tragedies that came along with them. He also tends to distract people with jokes, and/or play things down when he's overworked himself or isn't feeling his best.
  • Team Mom: Self-described as the "mother" of his friends.
  • Tension-Cutting Laughter
  • Third Eye: He has one that he usually keeps covered under his bandages.
  • Trickster Mentor: Zange often plays pranks and meddles in the lives of the other characters in such a way that people question whether he's a nice guy or not, especially in the cases of Ririchiyo and Watanuki. His actions usually end up helping them with their problems in one way or another.
  • Unhappy Medium: Inheriting the clairvoyant powers of the Hyakume is a great burden for his body, resulting in his poor health. It's also implied he has to carry over all the painful memories of his past lives every incarnation.

Tropes that apply to the second half of the series

Zange died of illness at age 24, two years after the enemy youkai's raid. He was reincarnated in Part II, and is currently 21.

  • Eyepatch of Power: He replaced his bandages with a patch for his new look in this incarnation.
  • Nice Hat: Natsume's reincarnation trades the bunny ears for one. This throws off Inugami's description of him to Watanuki.
  • We Used to Be Friends: Doesn't involve a falling out of any sort, but reincarnated!Watanuki lacks his past memories and didn't grow up with reincarnated!Zange as a "Childhood Friend", so they're practically strangers. They also rarely get to interact with each other since in this life, Zange's not Watanuki's SS Agent, and there are moments where it's painfully obvious that Zange misses their old relationship.

  • Uncanny Valley: invoked His unmoving facial expression seriously creeps out the other residents.

Jyoutarou's son and assistant in the kitchen.

Homare Nekozuki

Shimon Satorigahara

She is the one responsible for the creation of the Maison de Ayakashi as part of her struggle to gain civil rights for other atavists back when she was younger. Known as the atavist with the strongest spiritual power, she has the ability, similar to that of Zange, of omniscience. Her power is so strong that she must stay cooped up at her family residence away from other people so she doesn't get overwhelmed by information.

  • Alliterative Name: Shimon Satorigahara
  • Ambiguous Innocence: Shimon doesn't seem to realize the horrible implications that come with causing the Hyakkiyakou so she can read the deceased atavists' "stories". She sees it no different from watching a movie to entertain herself and she thinks there's really nothing wrong with having the atavists killed because they can be reborn anyway.
  • Auntie Pennybags: The main characters are a bit taken aback when meeting her for the first time; her personality doesn't really fit her status and wealth.
  • Big Good: She founded the Maison de Ayakashi and was responsible for encouraging peace amongst atavists rather than hunting them down. Subverted when it's revealed she's actually The Woman Behind the Man.
  • Birds of a Feather: She was this with Mikoto in the original timeline. They bonded because their status as atavists forced them to live isolated from the outside world.
  • Cool Old Lady: Until after the timeskip.
  • Genki Girl: An old lady version.
  • Go Mad from the Isolation: Living her entire life secluded from the outside world has resulted in Shimon becoming obsessed with reading the minds of the atavists to learn their life stories. She organizes the Hyakkiyakou with Inugami's help to get as many dead atavists as she can just to see their stories.
  • It Amused Me: She founded the Maison de Ayakashi to lure atavists out of their households and makes Inugami start the Hyakkiyakou so she can amuse herself by reading the deceased atavists' minds.
  • It's All About Me: She only cares about what she wants and will do anything to get it, without even considering how it might affect others. She doesn't even care about having people killed just so she can get to know their stories from their corpses.
  • I Was Quite a Looker: She was really cute when she was a young girl, as her reincarnation shows.
  • Lack of Empathy: She's perfectly happy with people dying so long as she gets an interesting story out of it.
  • Living Emotional Crutch: To Inugami, who can't bear the thought of living without her to the point that he keeps resetting time just so he can spend more time with her after she dies and kill atavists to keep her happy.
  • Mayfly–December Romance: In the original timeline, after Mikoto became The Ageless Shimon promised to remain with him even when she grew old and he stayed the same. Shimon wanted to let her reincarnations keep Mikoto company, but Mikoto only wanted the Shimon he knew, which is why he started resetting time after she died.
  • Mystical White Hair: Her hair has always been white, as a hint of her great spiritual power.
  • Power Incontinence: Due to her overwhelming power, she has to stay secluded from other people or she'd be overwhelmed by information. Her only constant companion appears to be her part-tengu servant.
  • Rapunzel Hair: Her hair is about as long as her body.
  • Seer
  • Unhappy Medium: Her Psychic Powers are so great that she has to be confined in her household without ever being allowed to go outside, otherwise she would get overwhelmed by information.
  • Unwitting Instigator of Doom: In the original timeline, Shimon got the idea that she and Mikoto could use the Thousand Year Sakura Tree to go back in time just for fun. Things went wrong and Mikoto got badly injured from wandering between space and time for several days, along with making him The Ageless.
  • White Hair, Black Heart: Her hair is naturally white and the fact that she's revealed to be The Woman Behind the Man and she doesn't care about having the atavists killed so she can get a good story from it definitely makes her qualify for the trope.
  • The Woman Behind the Man: She's actually behind the Hyakkiyakou along with Mikoto, wishing to see the "story" in the mind of the dead atavists.

Kuroe Karasuma

Shimon's assistant who is always beside her. She's part-tengu.

  • Alliterative Name: Kuroe Karasuma
  • Bare Your Midriff: Her youkai form wears a midriff-exposing outfit.
  • Blood Knight: She gets quite... excited when she gets to fight someone strong.
  • Combat Sadomasochist: She shows shades of being one, getting aroused when an opponent beats her down.

  • Girlish Pigtails: Her reincarnated self has these.
  • Girliness Upgrade: Her reincarnated self dresses in more feminine clothing compared to her previous incarnation.
  • Rapunzel Hair: Her reincarnated self.

  • Ship Tease: Gets some with Kagerou at the end.
  • Subordinate Excuse: In the final chapter, she becomes Kagerou's follower after he inspired her to change her fate, which made her fall for him.
  • Sugar-and-Ice Personality: She's always emotionless, we only see her sugary side when she's with Kagerou in the final chapter.
  • Tengu: She's a half-tengu and the clothes she wears in her youkai form resemble those of a traditional tengu.
  • Underboobs: The outfit she wears in her youkai form exposes the bottom of her breasts.
  • Winged Humanoid: She has a pair of wings on her back due to being half-tengu.
  • You Gotta Have Blue Hair: She has dark blue hair.

Mikoto Inugami

A mysterious atavist with the ancestry of a dog god. He's the leader of the rogue atavists.

  • The Ageless: His body was left permanently as that of a young boy as a side effect of trying to use the Thousand Year Sakura Tree to go back in time.
  • Big Bad: He's trying to make the Hyakkiyakou and is the responsible for the deaths of the main characters in the first half of the history. The rest of the series is about trying to stop him from doing the same thing again.
  • Birds of a Feather: With Shimon. They were both atavists who were forced by their households to live isolated from the world, which is what drew them together.
  • Cat Smile
  • Curse: He can force atavists into their youkai form and drive them mad.
  • Cute Little Fangs
  • Devoted to You: The entire purpose of Inugami's life is to be by Shimon's side and keep her happy, even if that means killing people for her sake. Since his unaging body makes it impossible for him to grow old with her, he keeps resetting time every time Shimon dies to be with her again.
  • Dying Declaration of Love: In his final moments, Mikoto admits he loved Shimon.
  • Evil Counterpart: He can be seen as one for Soushi. They are both powerful atavists who were kept prisoners by their households and ran away in order to gain their freedom. Once they were finally free, they decided to become the servant of a girl they fell in love with because she gave them a purpose in life. Also, they are both dogs with white hair.
  • Facial Markings: He has a Sharingan-like tomoe symbol on his forehead.
  • Fangs Are Evil: His sharp fangs denote how dangerous and evil he is.
  • Faux Affably Evil: He acts polite to his enemies, but his actions and motives are the exact opposite. He drops it when he's having casual conversations with his friend Watanuki; he then openly acts like a total jerk.
  • It Amused Me: He likes to bully Watanuki's reincarnated self for amusement's sake, as a requirement for their "friendship". He even punishes Watanuki when he fails to amuse him.
  • Jerkass: As far as Inugami is concerned, you're either garbage to be ignored or a tool for his and Shimon's entertainment. He even treats his Only Friend Watanuki like a slave.
  • Locked into Strangeness: His hair was originally black, but it turned white after he tried to use the Thousand Year Sakura Tree to go back in time and wandered between space and time for several days.
  • Love Makes You Evil: Because he loves Shimon and wants to keep her happy, Inugami created a horrible "Groundhog Day" Loop in which he starts the Hyakkiyakou to kill the atavists over and over again just to let Shimon get some entertainment from reading their minds.
  • Love Martyr: To Shimon. He loves her even despite that her whims and twisted childishness have made him into an immortal and forced him to lock himself in a "Groundhog Day" Loop where he has to kill the same people over and over again just to keep Shimon entertained.
  • Mayfly–December Romance: Mikoto became The Ageless because of the powers of the Thousand Year Sakura Tree. So he got to watch Shimon grow old and die while he remained the same. He found a way around this by using the Thousand Year Sakura Tree to go back to the time before Shimon died over and over again.
  • Morality Pet: Seems to be this to Shimon. He's the only person she appears to genuinely care about besides herself. Once he dies, Shimon for the first time ever comes to feel grief over someone's death instead of excitement to know their story.
  • Mystical White Hair: A mysterious atavist with white hair.
  • Older Than He Looks: He looks like a young boy, but he's really as old as Shimon. His growth got halted due to a side effect of trying to use the Thousand Year Sakura Tree to travel to the past. And that's not counting all the time he spent in several time loops not shown in the manga.
  • Only Friend: He was this to Shimon, being the only one to keep her company while she had live secluded from the entire world because of her powers. However, things took a turn for the worse when Inugami became immortal and Shimon started to get too interested in the atavists' stories...
  • Perpetual Smiler
  • Pet the Dog: At first, it seems he only likes to mess around with reincarnated Watanuki, but Inugami did care for him in his own way. He goes as far as to leave him a goodbye letter before resetting the timeline. Despite trying not to, Inugami keeps his soft spot for Watanuki even after that, which leads to his ultimate defeat.
  • Prematurely Grey-Haired: His black hair turned white after he tried and failed to use the Thousand Year Sakura Tree to go back in time.
  • Reincarnation: A given for atavists, but it's implied he eventually reincarnates as Watanuki's son.
  • The Runaway: He ran away from his household because they forced him to live under house arrest for being the atavist of the family.
  • Single-Target Sexuality: He loves Shimon and only her. Not even a reincarnation will do for him, which is why he goes back in time every time she dies.
  • Undying Loyalty: In a quite literal sense, to Shimon. Inugami dedicates his unaging life to serving Shimon, even killing the atavists for the sake of her amusement. He goes as far as to go back in time every time she dies just to be by her side for longer.
  • Unusual Eyebrows: He has dot-shaped eyebrows. In the final chapter, we see Watanuki and Karuta's child has Inugami's eyebrows, implying it's Inugami reincarnated.
  • Vitriolic Best Buds: He forms this relationship with Watanuki's reincarnation in Part II. At first, it only seems like Inugami only wants to bully Watanuki and treats him more like a toy than a friend, but it eventually becomes clear that Inugami did come to cherish their friendship even when he tried not to.
  • White Hair, Black Heart: He has white hair and is the main antagonist in the series.
  • Zettai Ryouiki: Grade A.
