Characters for the series, Isuca.
Warning: There will be unmarked spoilers. Read at your own risk if you haven't gotten far into the series.
An ordinary teenage boy who accidentally stumbles upon an exorcism. In doing so, he learns that he has supernatural powers, "The Eye Of Truth" which allows him to learn the True Name of supernatural beings or those with special powers, and basically enslave them, if he so chooses.
- Above the Influence: This guy could give Ghandi lessons in restraint.
- Accidental Pervert: Through the course of the series, he ends up being forced into an innocent cohabitation with four women, three of whom have absolutely no nudity taboos in a series with plenty of improbable Clothing Damage. This trope is completely unavoidable, to the chagrin of the fourth girl and himself.
- Actual Pacifist: Given a choice, he'll always go for the peaceful solution, due to his lack of experience or training. It seldom works for him.
- Adorkable: Awkward, clumsy, and a bit socially inept, all the girls at house Shizumu like him because he's a genuinely nice guy who seeks their well being above his own.
- Badass on Paper: He's got quite a few rather impressive accomplishments under his belt. Still, these accomplishments occurred under very unique circumstances and are not truly a display of his skill or personal strength. This comes to bite him hard in Chapter 41.
- Cursed with Awesome: As a result of his special powers, he effectively owns four very attractive women, and gets to kiss them all on a regular basis. Unfortunately, one of those four women is a Shana Clone, and his special powers also attract the attention of numerous supernatural horrors that want to kill him, and effectively eat his soul.
- Distressed Dude: Due to his general lack of training or practical experience, he is often the victim of this. Still, this doesn't stop him from actually being useful or coming to the aid of others, particularly Sakuya and Suseri.
- The Dulcinea Effect: It's the primary reason he's in his situation. He just can not resist coming to the aid of a woman in distress. Even if she will respond with violence.
- Face Fault: His reaction when Suseri announced wanting his children, in front of him and Sakuya.
- Giver of Lame Names: Lampshaded and subverted. The names he chooses may seem horrible at first glance, but actually fit surprisingly well.
- House Husband: He cooks, cleans, and does laundry very effectively without complaint.
- I Know Your True Name: The primary benefit of his supernatural power.
- Magic Kiss: His powers effectively work this way. In exchange for learning a supernatural being's True Name, he shares a portion of his spirit with it.
- Masculine Girl, Feminine Boy: The Feminine Boy to Sakuya's Masculine Girl. He is a nice and sensitive Non-Action Guy and basically a House Husband in training, while Sakuya is short-tempered and aggressive Action Girl and without him, her house is a complete mess.
- Nice Guy: The nicest guy in the whole series.
- Non-Action Guy: He doesn't have combat skills and always goes for the peaceful solution. Sakuya is the one who deals with the Demon Slaying.
- Now, That's Using Your Teeth!: He blocks a blow from a cursed Katana with his teeth, and that is how he acquires Yashao.
- One Head Taller: Than Sakuya.
- Ordinary High-School Student: An ordinary high-school student who ends up involved with an exorcist girl and discovers he has an unusual ability called the Eyes of Truth which allow him to divine the true name of a supernatural being or person with supernatural powers when he kisses them.
- Parental Abandonment: His parents left him alone in his dorm while he was attending middle school "for training." Unfortunately, they also cut off his allowance, forcing him to find a job. He winds up working for Sakuya.
- Second Year Protagonist: He is a second-year high school student and the main character of the story.
- Supreme Chef: His cooking skill is legendary, in universe. He can even make meals with which he is not familiar with relative ease.
- Took a Level in Badass: By the time chapter 48 rolls around, he's able to hold his own in demon-slaying, and can wield Yashao like a master swordsman.
- Understanding Boyfriend: He does his best to be this. He generally takes everything the four girls in his life throw at him in stride.
- Unlucky Everydude: While it's debatable if meeting Sakuya Shimazu is unlucky or not, the fact that his "Eye of Truth" power, he didn't even know he had, attracts the attention of many supernatural entities, most of whom are mortal threats certainly fits.
The primary female character and leading love interest in the story. Current (temporary) head of the Shimazu clan.
- Action Girl: A demon hunter who uses Sacred Bow and Arrows as her Weapon of Choice.
- Action Girlfriend: She's a demon hunter who ends up dragging Shinichirō into her world, which allows him to discover his supernatural powers and join her in exorcisms.
- A-Cup Angst: She is not happy about her flat chest. Goes with being a Shana Clone.
- All of the Other Reindeer: Is treated as an outcast by the Shimazu family because her father is a Western Mage.
- Anger Born of Worry: The first thing she does after Shinichirō is returned safely, and they're alone, is chew him out because she was terrified that something horrible had happened to him.
- Bitch in Sheep's Clothing: In public, she's very kind and polite. In private, she's a holy terror.
- Clingy Jealous Girl: She really does not like it when any other girl gets too close to Shinichirō, especially Suseri.
- Defrosting Ice Queen: She starts out as a Bitch in Sheep's Clothing with a nasty temper, but mellows over the course of the series, thanks to Shinichirō's influence. Also as befits a Shana Clone.
- Demon Slaying: It's her job as a member of the Shimazu clan.
- Face Fault: When Suseri announced being willing to become Shinichirō's concubine for the sake of bearing his children before both Shinichirō and herself, she and Shinichirō wear the exact same expression.
- Hair Decorations: She has a bow tying her hair back in a ponytail.
- Hair-Trigger Temper: She has a pretty nasty temper, lashing out at Shinichirō over the smallest things.
- Hime Cut: Has this traditional hairstyle, befitting her position as the temporary head of the Shimazu clan.
- Hypocritical Humor: Sees nothing wrong with living in a pigsty, yet is terrified of rats.
- Masculine Girl, Feminine Boy: The Masculine Girl to Shinichirō's Feminine Boy. She is short-tempered and aggressive Action Girl and without Shinichirō, her house is a complete mess. Shinichirō, on the other hand, is a nice and sensitive Non-Action Guy and basically a House Husband in training.
- Ojou: Comes from a rich family.
- Older Than She Looks: She is a high school student, but she looks like a 12 year old.
- Parental Abandonment: Her parents went out to subdue a spirit, they did not return, and the only witnesses refuse to tell her what happened, or why.
- Properly Paranoid: Having your father's side of the family trying to kill you in the most sadistic way possible, and having your mother's side of the family trying to make you "disappear" will make most people have this reaction.
- Rapunzel Hair: Has waist-length hair.
- Reluctant Fanservice Girl: To her dismay, she usually suffers from heavy Clothing Damage or ends up exposed in some other embarrassing way.
- Sacred Bow and Arrows: Sakuya uses a bow and arrows with spiritual power to seal monsters.
- Second Year Protagonist: A second-year high school student like Shinichirō and the main heroine of the story.
- Shana Clone: Has just about every trait for this trope. A teen with a childish body, prone to wear school uniforms with Grade A Zettai Ryouiki, waist-length hair, a severe Type-A Tsundere, and is also an heiress to a wealthy family who treats the hero like an inferior (though like the original Shana, she does start to grow out of this).
- Sour Outside, Sad Inside: Her harsh and aggressive personality becomes much more understandable when you find out her parents disappeared, nobody in the Shimazu clan will tell her anything about it, and most members of her clan would prefer her dead or gone.
- Tiny Tyrannical Girl: Short, bossy and aggressive, as expected from a Shana Clone.
- Took a Level in Kindness: By the later chapters, she becomes nicer thanks to Shinichirō.
- Token Mini-Moe: The youngest-looking girl in the cast.
- Trademark Favorite Food: Irish Stew. This being something that Shinichirō is not familiar with has not stopped her from enjoying it. Even though he doesn't make it "right," Sakuya has no complaints regarding its taste.
- Trash of the Titans: Her house starts out as a huge mess. She then hires Shinichirō to clean it for her.
- Tsundere: All part of being a Shana Clone. She treats Shinichirō like dirt when it's obvious she has feelings for him, gets easily embarrassed and uses violence to stop being embarrassed.
- Tsurime Eyes: Has the typical eye shape found in Tsunderes.
- Why Did It Have to Be Snakes?: She is terrified of rats.
- Zettai Ryouiki: She wears white thigh-high stockings.
Sakuya's younger cousin and rival for the title of being head of the Shimazu clan.
- Armor-Piercing Question: In confronting her mother, she makes Sagiri realize just how stupid the attack on Shinichirō was.
- Suseri:"Stories spreading about Shinichirō being attacked in the middle of the night. What do you think would have happened if Shinichirō died?"
- Badass Boast: She delivers one to her mother before leaving, never to return.
- "Please don't harm Shinichirō again, Mother. I don't know if I will be able to hold back."
- Bedmate Reveal: She sneaks into Shinichirō's bed, naked, in chapter 48. Sakuya finds them in a very compromising position moments later.
- Big Breast Pride: Her large breasts are her primary perceived advantage against Sakuya for Shinichirō's affections.
- Big Damn Heroes: She and her Thunderbeast, Shiro, rescue Shinichirō when he was being attacked from behind by a skeleton that crawled out from the ground in chapter 48.
- Bi the Way: She used the same "bathing" technique on both Shinichirō and Sakuya, and frequently "bathes" with her handmaiden as well. Make of that what you will.
- Blow You Away: She has a ferret spirit that controls the wind.
- Calling the Old Woman Out: Thanks to Shinichirō, she decides not to let Sagiri simply push her around anymore. She eventually succeeds by the time chapters 46 and 47 rolls around, where Suseri reveals she has proof of her mother's wrongdoing, and very politely tells her self-righteous mother not to harm Shinichirō again and that she can't return to Kamakura. Suseri's mother does not take it well.
- Death Glare: She gives one to Sagiri when she confronts her about killing Shinichiro in chapter 46. She also glares at Sagiri after knocking Domeki down by the end of chapter 47 before she leaves Sagiri's house forever.
- Defrosting Ice Queen: She starts out as somewhat emotionless and solely focused on becoming the next head, but she begins to open up to Shinichirō after he spends a little time with her and learns more about her strict upbringing due to her mother.
- Demon Slaying: Again, it's her job as a member of the Shimazu clan.
- Do You Want to Copulate?: She's desperate to bear Shinichirō's child, and doesn't understand why sneaking into his bed would upset him.
- Driven by Envy: Against Sakuya. While her mother made her go through Training from Hell, it looked like Sakuya had a normal childhood, laughing and playing with her parents.
- Girlish Pigtails: As befits a Miko, she wears her hair this way.
- Heroic Seductress: Employs this against Shinichirō in episode 3 in an attempt to lure him away from Sakuya. She starts by washing his back with her breasts and later says she'll do anything he wants her to in exchange for giving her power similar to how he did to Sakuya.
- I Just Want to Be You: Deep down, she envies Sakuya's life because of her easier upbringing and her position as the family head. This is why her true name is Sakuya.
- I Know You Know I Know: She spots conclusive proof that her mother was present at the scene of the war zone that is the Sakuya house in chapter 42.
- Jerk with a Heart of Gold: She may be a rude and callous jerk, but doesn't share her mother's self-righteousness.
- Lethal Chef: Lampshaded. She thinks she's good at making soup. She isn't. Her handmaiden specifically says that it's a life-threatening endeavor.
- Mid-Season Upgrade: She adds a Thunderbeast to her arsenal of spirits, thanks to Shinichirō.
- Miko: She fits just about every aspect of this trope, from personality to uniform. The only thing she's not seen doing that a Miko does, is maintaining a shrine.
- No Social Skills: Her Fantasy-Forbidding Mother didn't think that dealing with the public was a necessary skill to be a clan head, and so Suseri is almost completely clueless when it comes to dealing with people. She gets over it later on.
- The Resenter: She resents Sakuya because of how strict her upbringing was, compared to how carefree the latter seemed to be... at first.
- The Rival: To Sakuya, though not by choice.
- Sacrificed Basic Skill for Awesome Training: Prior to meeting Shinichirō, she didn't even know how to use a mop, or how to buy groceries.
- Shameless Fanservice Girl: It starts in episode 3, at Nadeshiko's urging, and just keeps going.
- She Cleans Up Nicely: Suseri looks fairly good in regular street clothing as seen in episode 8. Prior to Shinichirō helping her to buy it, she always wore her school uniform or a Miko outfit to perform exorcisms with.
- Shock and Awe: Her second spirit, a thunder beast, uses lightning as well as physical attacks.
- Sibling Rivalry: By chapter 49, her relationship with Sakuya more or less boils down to this.
- Slipping a Mickey: She has her maid drug Shinichirō's tea so she can sneak into his room at night and try to seduce him without resistance, due to him being temporarily paralyzed. Shinichirō only forgives her because she truly does not comprehend why that is inappropriate.
- The Stoic: Learning how to emote is also something her mother thought "unnecessary."
- Sugar-and-Ice Personality: Comes across as cold, distant and stoic, but this is only the result of her strict upbringing and once he becomes closer to her, she reveals a cute and loving side to Shinichirō, deciding she really wants to bear Shinichirō's children, even if it means being Shinichiro's concubine.
- Summon Magic: She summons spirits to help her in battle.
- Took a Level in Kindness: She's a lot nicer in the later chapters as opposed to her first appearance due to Shinichirō's influence.
- Undying Loyalty: To Shinichirō, and after growing closer to him starts showing shades of this to Sakuya as well.
- What Is This Thing You Call "Love"?: This is the biggest hurdle in her understanding her feelings for Shinichirō, as she has no benchmark for comparison. The one thing that is constant is that she's certain she wants to bear his children, whether she's legally married or not.
- Yamato Nadeshiko: Fits this role completely.
- You Can't Go Home Again: In chapter 47, when the battle's over, Suseri flat out tells Sagiri that, after all that's happened between them and the fact that her mother attempted to harm Shinichirō, she can't return to Kamakura.
Suseri's maid. She was assigned by the Shimazu clan to tend to all of Suseri's daily, mundane needs.
- Affectionate Nickname: Suseri calls her "Mari."
- Chaste Hero: She has no desire for romance, yet.
- Combat Medic: She specializes in healing magics.
- Hair Decorations: She wears a ribbon like a headband to keep her bangs out of her face.
- Meido: When she's not helping Suseri with Demon Slaying, she is this, for which Shinichirō is rightly grateful.
- Shipper on Deck: She strongly supports Suseri + Shinichirō.
- Supreme Chef: To the surprise of everyone, her cooking is enough to impress Shinichirō.
A nekomata that Shinichirō unwittingly rescues from Sakuya. She ends up being his first True Name slave, revealing his "Eye of Truth" ability in the process.
- Bare Your Midriff: Her maid outfit clearly exposes her abdomen.
- Cat Girl: She's a Nekomata.
- Cute Bruiser: She's very cute, but she can punch holes in concrete walls.
- Cute Little Fangs: Goes along with being a nekomata.
- Does Not Like Shoes: She's barefoot in every one of her appearances.
- The Glomp: Her favorite way of greeting Shinichirō, especially if she's completely nude.
- Going Commando: She does not like wearing panties or bras. Undergarments are apparently an alien concept to her. Partially justified in that panties aren't exactly designed to accommodate a tail. Another thing justifying this is that her past life was a common house cat. House cats don't wear clothes.
- Happiness in Slavery: All that's missing is a collar engraved with "Property of Shinichirō Asano." If she ever got one, she'd be ecstatic!
- Innocent Fanservice Girl: If given permission, she would happily run around naked. In fact, she sees nothing wrong with glomping Shinichirō and giving him Marshmallow Hell while naked.
- Little Bit Beastly: In her human form, she has cat ears and sometimes a tail.
- Mega Neko: In her true form, she's a very big kitty indeed.
- My Master, Right or Wrong: Lampshaded. She calls Shinichirō her master, and will happily do anything she can to protect and serve him.
- Power Makes Your Hair Grow: Absorbing some of Shinichiro's energy causes her hair to grow incredibly long for the brief time.
- Undying Loyalty: To Shinichiro.
A cursed katana that Shinichirō acquires upon learning its True Name.
- Ambiguously Brown: Her ethnicity is unclear, but she's very dark skinned.
- The Baroness: She has quite a few of these traits under "the sexpot" version.
- Boobs of Steel: Quite literally. She's a katana spirit. Still, her size is just a bit smaller than Suseri's.
- Cultured Badass: Her speech is exceedingly polite and graceful, yet her human form can single-highhandedly defeat Sakuya, Suseri, and an empowered Tamako simultaneously with a single blow, and chapter 41 says her human form is weaker than her katana form.
- Femme Fatale: Played as straight as they come. She plays up her sexuality for all its worth, but if Shinichirō accepts, he could die.
- A Form You Are Comfortable With: Implied. She's supposed to be the spirit of an ancient samurai warrior, yet she's an Ambiguously Brown Darkskinned Blonde Femme Fatale.
- The Gadfly: She loves giving Shinichirō Marshmallow Hell while Sakuya is watching, just to see her react.
- Informed Attribute: She's called "evil" by Nadeshiko and Nami, and she was certainly quite hostile when introduced in her katana form, however, once she's "awakened", and taken on a human form, the worst she's done is playfully strip Sakuya and Suseri, as well as given Shinichirō Marshmallow Hell while nude. Suseri and Sakuya have both done worse. Even her initial hostility as a katana can be justified by the fact that she was not aware of her actions, and was acting purely on instinct.
- Katanas Are Just Better: She's a Katana.
- Lady of War: She fits everything about this trope.
- Marshmallow Hell: She gives one of these to Shinichirō to stop him from commanding her to return to her katana form. After that, it's one of her favorite activities with him.
- Naked on Arrival: Makes her first appearance in her human form while completely nude.
- Nominal Hero: Lampshaded. Nami Shimazu explicitly calls her "evil." She's only loyal to the heroic side of the story because Shinichirō is her master.
- The Nudifier: She can, and will strip the other ladies in the harem naked when she's annoyed, or being flirtatious, or both.
- Shameless Fanservice Girl
- Spell My Name with an "S": She's been called Yashano, Yasyano, Yashao and several other names throughout the manga.
- The Tease: She's really good at this. She's offered "to teach Shinichirō about women."
- Visual Pun: She's a naked blade, and her human form is nude.
- Weapon Wields You: She has this ability in her Katana form. Good thing Shinichirō is her master.
The teacher/guidance counselor that recommended Shinichirō work at Sakuya's house at the beginning of the story, so he could pay his bills. She also happens to be a high ranked family servant of the Shimazu clan.
- And Now You Must Marry Me: Lampshaded and averted. She said this word for word when she noticed Shinichirō's talents as a House Husband, but she was kidding, or was she?
- Date Peepers: Throughout all of chapter 46, she's been watching over Sakuya's date with Shinichirō, and sending texts to Sakuya's cell phone with strategic hints to help make the date a success. Shinichirō sees through it almost immediately.
- Everyone Has Standards: She was shocked and angry when Shinichirō revealed Sagiri's attempted assassination, and "Isuca's" Villainous Rescue.
- The Gadfly: She loves teasing Shinichirō and Sakuya just to get a reaction.
- Harem Nanny: Contrary to most examples of this trope, she wants romantic progression from Shinichirō to his girls, particularly towards Sakuya and/or Suseri.
- Ironic Name: Her name is Nadeshiko, yet she completely averts the trope.
- Manipulative Bitch: Although a benevolent one, at least towards the main characters.
- Ms. Exposition: Justified, she's a teacher, and it's her job, as the head of the recon squad to explain the Monster of the Week, and the supernatural setting to Shinichirō (and the audience.)
- Shipper on Deck: She's constantly scheming behind the scenes to see Shinichirō grow closer to both Sakuya and Suseri.
The current (true) head of the Shimazu clan and the grandmother of both Suseri and Sakuya.
- Badass Adorable: Though she looks like a 10-year-old, she is easily the strongest Demon Slayer of the Shimazu clan.
- Gamer Chick: She's quite skilled in video games. Her Secret Test of Character involves one. An Omake has her finding out about M.M.O.s and disappearing for a week.
- Loophole Abuse: Though she is either forbidden or unable to speak of what truly happened to Sakuya's parents, that doesn't stop her from kissing Shinichirō and letting him read her memories.
- Older Than She Looks: She looks like she's 10-years-old. Justified as she is using puppets to move about. Her real body has yet to be revealed.
The Western Mage, Kaya "Isuca" Asahina
A powerful mage that seeks the destruction of the Shimazu clan, and everyone in it.
- An Arm and a Leg: Suffers this after a confrontation with Nami Shimazu in the manga, with Sakuya in the anime.
- Artificial Human: A homunculus created by alchemy.
- Bad Guys Do the Dirty Work: She's the one who ends up defeating Sagiri Shimazu in chapter 41 of the manga.
- The Bully: Certainly has elements of this. Goes out of her way to harass the main characters? Check. Takes sadistic pleasure in the main character's suffering? Check. Enjoys seeing the characters struggle in futility? Check. Hates when the characters stand up to her? Check. Sore Loser? Check.
- Cast from Lifespan: Chapter 42 reveals that the same spiritual energy that animates her body also fuels her magic.
- Chronic Backstabbing Disorder: As of chapter 42, only Ildanna is unaffected, and that's presumably because he knows her True Name.
- Cute Little Fangs: She sports one every time she brings up her Slasher Smile.
- Cute and Psycho: The psycho part is lampshaded in the anime.
- Dead Man Walking: Chapter 43 reveals that her homunculus body has already passed its expiration date.
- Freudian Excuse: She has memories of being sadistically killed by Nami Shimazu. She is forced to relive that pain every time she "sleeps." Chapter 49 implies these memories are false.
- Light 'em Up: She uses light-based attacks and magic.
- Luke, I Am Your Father: There are strong hints that the spirit belonging to Sakuya's mother is in the homunculus body. The most notable of which are when she talks in her sleep.
- Moral Myopia: She sees nothing wrong with sadistically slaughtering everyone in the Shimazu clan, and (in the anime) only objects to her clan summoning monsters to attack innocent, uninvolved civilians because it's inefficient, not because civilians are being attacked, but should anyone actually defy her successfully, or gods forbid, actually cause her the slightest injury, even accidentally, it's an unforgivable offense worthy of a Fate Worse than Death.
- Slasher Smile: This might as well be her default expression. The only time this changes is when Sakuya retaliates against her abuse and actually manages to cause damage, and then her expression is a mask of pure rage.
- Villainous Rescue: Towards Shinichirō in chapter 41.
- Yandere: To Shinichirō at serious Fan Disservice levels. Her actions in chapter 42 border on Attempted Rape.
Suseri's mother. She is obsessed with making her daughter the next clan head and is adamantly opposed to Shinichirō, whom she considers inferior to the point of being sub-human.
- Abusive Parent: She constantly tells Suseri that if she fails to become the clan head, ousting Sakuya in the process, then she is worthless as a human being, and that's on a good day. Given that Sagiri was thrown aside for her sister when she was young, this is understandable.
- Berserk Button: Anything that reminds her of Kaya will make her furious.
- Didn't See That Coming: She was utterly shocked when Suseri presented her fan to her in chapter 46, and leaves her house at the end of Chapter 47.
- Evil Matriarch: She's quickly heading into this, if she's not there already.
- Eye Scream: She's missing her left eye, and has a rather nasty scar on that side of her face.
- Fantasy-Forbidding Mother: She tries to forbid Suseri from seeing, hearing, doing or even learning about anything that she believes has nothing to do with running the Shimazu clan. It eventually comes back to bite her.
- For Your Own Good: She claims that forcing Suseri to become a Puppet King running the clan will make Suseri happy, later. She then goes on to lampshade it as an excuse for trying to kill Shinichirō. Suseri points out how suicidally stupid the act is.
- Freudian Excuse: She claims her mother, Nami Shimazu, forced her to undergo the same upbringing that Suseri is going through, to force her into the role of Clan Head, but when she proved incompetent, she was thrown aside for her sister, Sakuya's mother, and then got that woman's "leftover husband" when she married Sakuya's father.
- Good Scars, Evil Scars: Bears one on the left side of her face, across where her eye should be.
- Insane Troll Logic: Why yes, Sagiri knows how to make her daughter, Suseri, happy. The secret is giving Suseri the same upbringing that made HER miserable, force Suseri to take up the reins of the Shimazu clan, as a Puppet King, find Suseri a "proper" husband, and to accomplish all that, all she needs to do is kill the guy who actually makes Suseri happy.
- It's All About Me: Any scene where she's ranting to herself or in her thought bubbles, you will see that this trope is her entire motivation for making Suseri a Puppet King. "Finally, after all my waiting, all my pain, all my humiliation, all my frustration will be avenged!"
- Jerkass: Let's face it, with her ruthless demeanor, arrogance, interest in making Suseri the Puppet King of the next clan and opposition towards Shinichirō to the point of killing him, Sagiri is not one of the nicest human beings by a long shot. Even Suseri and Shinichirō are aware of this.
- Jerkass Has a Point: Sagiri has a point about Shinichirō being a worthless husband since she was underwent the same upbringing that Suseri put herself through. She was cast aside in favor of Kaya, who eventually married Sakuya's father. Sagiri called Sakuya's father a worthless husband as well.
- Kick the Dog:
- She attempts to kill Shinichirō because she deemed him as a worthless husband.
- In Chapter 47, she threatens Suseri with her guardian spirit while she is leaving and strikes Matsuri down. It doesn't work.
- Knight Templar: Sagiri views her actions as righteous, and won't change her mind no matter how seemingly heinous her actions can become.
- Laser-Guided Karma: Her self-righteous behavior towards Suseri, as well as her viewing of Shinichirō as an "unworthy" husband to Suseri to the point that she decides to kill him, eventually leads to Suseri to actually refuse to return to Kamakura and tell her mother not to harm Shinichirō again, meaning Sagiri has essentially lost the only remaining person she really loves.
- Misplaced Retribution: She starts lashing out at Matsuri the moment Suseri stands up to her, especially when Suseri points out just how idiotic and counter-productive killing Shinichirō would have been for her.
- Moral Myopia: After all the crap she's pulled, she has the gall to call Suseri an "unreasonable child" in chapter 47, and then rudely and dismissively tells her to "make it quick" regarding her complaints. Suseri is all too happy to comply.
- Suseri: "...The other day, I found this in the Yokohama Garden. [presents her mother's fan to her] That night... you attacked Shinichirō-sama, didn't you, Mother? [gives her a Death Glare] Please, tell me the reason, Mother."
- Never My Fault: At the end of chapter 47, she threatens Suseri with her guardian spirit, and when Suseri's maid pleads with her to relent, she tries to strike down said maid for "becoming a hindrance." She is then shocked that Suseri strikes down the guardian spirit and walks away. Her last appearance has her honestly, and completely, failing to comprehend why she never gets what she wishes for.
- Not So Stoic: Despite her stoic and strict personality, Sagiri can easily lose her cool, such as when Kaya attacks her in Chapter 41, and when Suseri tells her about her aunt's marriage and finally decides to leave Kamakura in Chapter 47.
- Peek-a-Bangs: She tends to cover the left side of her face with her hair to hide her scars.
- Pride: She is almost blinded by her arrogance.
- Red Right Hand: She has a blind left eye which is always covered by her bangs.
- Sore Loser: Sagiri does not take it well when Suseri decides to leave Kamakura to follow her own path to become head of the next Shimazu clan.
- Spell My Name with an "S": Despite her official romanization rendering her name as Sagiri, she is sometimes called, Saguri, Sakiri, among other names, and there doesn't seem to be a consistent pattern.
- The Svengali: She sees Suseri, her own daughter, as being a valuable asset for only one reason, becoming a Puppet King to run the Shimazu clan. Towards that end, she has forced Suseri to become the most powerful summoner possible, and will not hesitate to sacrifice her if she fails in any test, even an impossibly deadly one, like subduing a Thunder Beast, alone and virtually unarmed. She is then shocked when Suseri eventually has had enough and leaves.
- This Cannot Be!: Several times. The most prominent is Chapter 41 with the Villainous Rescue.
- Troubled Abuser: She claims to be this, due to the actions of her mother, Nami Shimazu. Her testimony does not fit with Nami's known behavior to date, however. The fact that she's also doing a good job of trying to murder Shinichirō with premeditation at the time does not help with her credibility.
- Ungrateful Bitch: Despite Shinichirō saving her daughter's life on numerous occasions, helping said daughter actually succeed at tasks that would make her a fine front runner for clan head, like subduing a Thunder Beast, if not actually guarantee the position, and generally proving himself an extremely valuable asset, she still deems him "unworthy" to be Suseri's husband, not because of any character or behavioral flaw, but simply because he's an "outsider." As such, he needs to be "removed." However, it eventually comes back to bite her.
- Vicariously Ambitious: Sees herself as the rightful ruler of the Shimazu clan, but since she can't take the position herself due to the clan's bylaws, she tries to force her daughter, Suseri into the position, as a Puppet King. She completely falls apart when Suseri declares that she's going to follow her own path, not the one her mother imagines for herself, even if she does become the Clan head.
- Villain Ball: Her "plan" in chapter 41 is, at best, incredibly short-sighted and inefficient. Even if she had succeeded in killing Shinichirō, she left her magical "fingerprints" everywhere, had no alibi, had already set herself up as the prime suspect in previous chapters, and would have had to contend with the testimony of two immortal witnesses that are physically incapable of lying. Furthermore, did she really expect that Suseri, as the daughter of a traitor, would be more welcome than a simple "black sheep" who is already slated for the job of clan head, in a clan that firmly follows the Sins of Our Fathers philosophy? And that's presuming that killing Shinichirō didn't doom the clan directly, as he was a pivotal part of the clan's defenses.
- Virtue Is Weakness: She thinks being married for love is actually a strike against Suseri's relationship with Shinichirō. Suseri can only pity her as she leaves the woman's house forever.
- Well-Intentioned Extremist: In her eyes, all of her Jerkass behavior is to ensure the safety and protection of her own clan and Suseri.
The Masked Mage Ildana
A masked man with long, blond hair whom The Western Mage calls "father" and whose orders she almost unquestioningly obeys, particularly when said orders involve attacking the Shimazu clan.
- Ambiguously Evil: It's not quite clear, yet, if his actions against the Shimazu clan are of his own volition, or if he's being controlled via his True Name, Tokiharu Asahina.
- Becoming the Mask: Literally! Sakuya blasts the mask off in battle, and there's nothing behind it but empty air.
- First-Episode Spoiler: The fact that he may be Sakuya's father is made immediately obvious on his first appearance.
- Large and in Charge: He's the tallest character yet shown, and seems to be the most powerful.
- Memento Macguffin: He wears a very distinctive ring that only one other person has ever worn in the series, Sakuya's father.
Akiyuki AsahinaThe chief of the Asahina clan, and the one giving the orders for the war of extermination against the Shimazu clan.
- Cain and Abel: He calls Ildana "nii-san," meaning "brother." Whether he's the Cain or the Abel is yet to be determined, but his actions to date would lead one to think "Cain."
- I Know Your True Name: Implied. He seems to be controlling Ildana that way. He specifically makes a point of gloating that Ildana has to follow his every order.
- The Man Behind the Man: As nasty as The Western Mage is, this guy is nastier.
- War for Fun and Profit: In addition to some, as yet, unmentioned grudge against the Shimazu clan, he's attempting to steal some gem that apparently allows Nami Shimazu to control her puppet bodies.
Lilia AsahinaA small girl introduced as the heir of the Asahina clan in chapter 26.
- Contralto of Danger: She speaks in beige prose when discussing the Asahina's plan to genocide the Shimazu clan.
- Hair Decorations: She has red bows tying her hair into twintails.
- Hypocrite: Knowing full well that the Asahina clan has broken into and attacked Shimazu clan houses, and public buildings, she attacks Sakuya from behind for "poor manners" when Sakuya infiltrates the Asahina main house looking for Shinichirō in chapter 43.
- The Mole: Her father has her spying on the homonculous, "The Western mage." Needless to say, she's not very good at it, and gets trounced almost immediately.
- Split-Personality Takeover: She may suffer from this. Every time the "teddybear" talks, it's in Beige Prose with a Contralto of Danger, leading to Troubling Unchildlike Behavior.
- Troubling Unchildlike Behavior: She discusses the Asahina's plan to invade and annihilate the Shimazu clan as if she was going on a picnic.
Kanae and Fuzuki
Two of Sakuya's classmates who idolize her at school for being "a proper upper class lady."
- The Gadfly: In one of the bonus chapters between 44 and 45, one of them is seen tricking Shinichirō into embracing her and then, when Shinichirō is out of sight, she reveals to Sakuya that she's Going Commando just to get a reaction.
- Locked Out of the Loop: They have no knowledge of the supernatural side of the world setting, the politics of the Shimazu household, Sakuya's Innocent Cohabitation with Shinichirō, or anything having to do with Sakuya's daily trials and tribulations.
- Muggle Best Friend: They have no special magic powers or abilities.
- School Newspaper Newshound: They write for the school newspaper.
- Those Two Guys: They're always seen together.
