Characters / Diabolik Lovers

A list of characters that appear in the Diabolik Lovers franchise.

In General

• All Abusers Are Male: Downplayed. Yes, the majority of the boys' actions are cruel and abusive, not to mention Karlheinz' treatment of his sons. However, Cordelia also stands among them as one of the more heinous abusers, and is the reason why the Sakamaki triplets are so psychologically warped.
• All Men Are Perverts: This is in play, but has a bit of a wrinkle given how blood-drinking correlates to sex - there is perversion, and then there's perversion.
  • Every boy wants Yui for her blood no matter how else they may feel about her, and this is a Kiss of the Vampire situation. The boys always enjoy drinking her blood and are fully aware that this is sexually gratifying to their victim/partner. Over time, Yui's protests about getting bitten start to ring hollow as she falls for her love interest. Typically the love interest genuinely comes to love her by the conclusion of the storyline, or if they are too troubled for that, they are at least headed in that direction.
  • Laito is the standout example since he is oversexed and lets everyone know it; Shu is also this but he's more a Covert Pervert.
• Brooding Boy, Gentle Girl: All the boys are the sadistic, abusive, and carrying around a lot of emotional baggage, while Yui is the sweet, kindhearted, and forgiving Gentle Girl.
• Cast Full of Pretty Boys: All the characters are youthful and attractive, and the majority of them are boys that serve as potential love interests for Yui.
• Fetishized Abuser: Yui's love interests act cruel, taunting, and forceful in regards to her. This is treated as their "Do-S" appeal — they are physically attractive and in complete control of the heroine, especially in bed.
• Interspecies Romance: All of Yui's love interests are vampires or other franchise-bespoke demonic beings, so this trope is a constant. There are ending that subvert it, though - Yui can become a vampire herself in some endings, and in later visual novels some of her love interests may become human.
• Themed Harem: Vampires and demons flock around Yui in increasing numbers as the series proceeds. While the visual novels are organized around story paths where Yui picks one of these boys and sticks with him, the TV series has a harem format so each boy gets their minute in the limelight.
• Took a Level in Kindness: Each love interest responds to Yui's kindness and empathy over time, becoming nicer in each of their endings. However, happily ever after is by no means guaranteed.
• Vampires Are Sex Gods: All the vampires are good looking, and their blood sucking is an unmistakable analogue for sex. Depending on the route, some of them are literal sex gods rather than just sex gods by proxy - at least, within the limits of a CERO D rating.

Main Characters

Heroine

Yui Komori

Voiced by: Rie Suegara (anime) (Japanese), Maggie Flecknoe (English), Vanessa Olea (Mexican Spanish).

The heroine of the franchise and the player character. After her father moves abroad, she is forced to live in a mansion with six mysterious vampires.

---

• All Girls Want Bad Boys: Despite their incredibly jerkass personalities and/or sadomasochistic tendencies, Yui ends up falling for one based on whose route she's in. She often asks herself why she doesn't try to escape, but she's just too intrigued by her chosen boy and quickly becomes invested in doing what she can to help him.
• Apologises a Lot: She is a Cute Clumsy Girl so this comes with the territory. The VNs tend to incentivize apologies; they usually count as masochistic responses so they lead to the good endings.
• Babies Ever After: In some routes of the visual novels.
  • In Azusa's More,Blood good ending, she and Azusa have three children. All of them are named after Azusa’s former “friends” and wounds: Justin, Christina, and Melissa.
  • In Ruki's Dark Fate Brute ending, Yui and Ruki are together and they have a son named Adam, but his biological father is Shin.
  • In their respective Lost Eden good endings, she is pregnant from Carla and Subaru.
• Blessed with Suck:
  • Yui's special blood makes her a Bishonen Vampire Magnet and ensures that the Distress Ball is always in her court.
  • In the Bloody Bouquet series of CDs, she's cursed with a spell that makes her blood inedible to vampires. However, by this point, she's already in a relationship with a vampire, they have intimate moments by drinking blood, and the curse slowly kills her if her man doesn't perform an Act of True Love.
• Butt-Monkey: Though Yui does not get beaten on like her Male Harem Lead counterparts, the boys almost all start out with zero regard for her bodily autonomy, and they regularly invade her physical space or pull her around by her arm. In the TV series she wakes up in a different outfit than she passed out in more than once. Their lack of regard for her privacy can veer into Played for Laughs territory when they walk in on her in the bath, which they enevitably will do.
• Damsel in Distress: She is in constant distress from the moment she walks into the Sakamaki manor. And sure, she slowly gets used to vampires drinking her blood on a regular basis, but there is a steady stream of other characters who need her for whatever scheme they are concocting - like Richter and Cordelia plotting to take over her body, or the Mukami brothers kidnapping her for the Apple of Eden plan, or the Tsukinami brothers kidnapping her again, etc, etc.
• Dating What Daddy Hates: After she starts getting involved with the vampires, she learns that her father is a vampire hunter. Plotlines that involve the Reverend Komori coming back are rare, but profoundly distressing for Yui because he disowns and tries to kill her.
• Dude Magnet: Justified because her special type of blood attracts the male vampires in the series; deconstructed since she has to deal with them biting and harassing her against her will. If she was just an ordinary girl they would simply kill her and find a new vessel.
• Dumb Blonde: Has platinum blonde hair, for someone who's Japanese, but not exactly the sharpest tool in the shed.
• Embarrassing Nickname: Is given a number of demeaning nicknames by the vampires.
  • Ayato calls her "Pancake" for her small chest.
  • Laito calls her "Bitch-chan". Crunchyroll translated it as "Little Bitch" for the anime, in the Mexican Spanish dub it was translated as "Pequeña Zorra"^note Literally "little vixen", but it's also translated, context-wise, as "little whore", and in the Portuguese dub its nickname was literally translated, as "Vadia".^note Literally "bitch" without the honorific "-chan", obviously. This one (alongside the nickname "Pancake" given by Ayato, literally translated as "Panqueca") was considered by many watchers as a "Blind Idiot" Translation, as most FanSubs used the original term.
  • Yuma calls her "Sow".
  • Kou calls her "M Neko-chan" (Masochistic Kitten).
  • Ruki calls her "Livestock".
• Extreme Doormat: The Mukami brothers are bothered by her acceptance of her lot at the Sakamaki manor instead of trying to escape, since escaping from veritable hell on earth is their backstory. The reason why she's like that in the first place is because she's told she'll get killed by the brothers if she dares to defy them.
• Fear of Thunder: She is afraid of thunder.
• Females Are More Innocent: Out of all of the main characters Yui has by far the most positive outlook on life, and she wants to help even those who have hurt her. However, this can be subverted if she's pushed over the edge. This is especially true in the first story, where she is fighting against Cordelia's influence.
• Feminine Women Can Cook: She enjoys cooking and is pretty confident in her abilities. About half of the boys disparage her efforts anyway. It's a fairly futile effort on her part; the Sakamaki brothers only eat for the fun of it and are very particular.
• Hair of Gold, Heart of Gold: Has blonde hair and is a Love Martyr well past the point of masochism.
• Haunted Heroine: She starts the story as an ordinary girl left at the entrance of a purportedly haunted mansion, and she has no idea what is in store for her there. While the house isn't technically haunted, it turns out that she is, and if she hadn't set foot in that place she may never have become aware of it.
• Hello, [Insert Name Here]: Yui Komori is her default name but it can be changed in the visual novels.
• It Sucks to Be the Chosen One: Having the blood of "Eve" a key element in Karlheinz's vampire eugenics plan means Yui has physically and emotionally abusive vampire boys hungering for her.
• Japanese Christian: She was raised Catholic and lived in a church before being sent to the Sakamaki manor. She aspired to become a nun before she ended up in the clutches of the vampires, but that dream falls to the wayside pretty quickly as her involvement with them deepens. Her belief in God (and her rosary) pay off through making it more difficult for Cordelia to fully possess her.
• Morality Pet: Her influence is the main reason the boys change their sadistic ways.
• Mysterious Past: Yui is the only major character whose past has not been revealed, despite the storytelling potential there. How Richter found her is still a mystery and the identities of her birth parents is unknown.
• Oblivious Adoption: The anime makes a plot point out of Yui learning that she is not blood-related to her father as a reason for her to remain with the Sakamakis despite their cruelty. The visual novels do not require that motivation and do not draw any particular attention to her adoption, no matter how improbable the prospect of a priest raising a child may be.
• Ordinary High-School Student: She thought of herself as a normal girl up until her identity as Cordelia’s vessel/the Chosen Eve is revealed.
• Pink Means Feminine: Her causal outfit in the early VNs and the TV series includes a pink top, and she is very feminine.
• Please Kill Me if It Satisfies You: She will sometimes make this offer if she thinks that her love interest is suffering due to her presence.
• Plucky Girl: When it comes to her love interest, she is incredibly persistent. No matter how much he may try to scare her off, Yui will discover one of his emotional weak points or find him in a distressing situation, and do her best to help him.
• Preacher's Kid: Her adoptive father is a priest, and she is a legitimately good girl.
• Smells Sexy: Due to her blood, her scent is extremely appealing to vampires. It is also very pronounced - like an olfactory beacon announcing her deliciousness to every vampire in the vicinity. She has a snowball's chance in hell of hiding from them.
• Stranger in a Strange School: The Sakamakis arrange for Yui to attend school with them at Ryoutei Academy as soon as she arrives at their house. The school is only a little weird, all concidered - it is a night school and the student body overrepresents child celebrities and the children of public figures, but it's not an All-Ghouls School. On the other hand, the supernatural segment of the student body just keeps rising...
• Super Drowning Skills: Yui's dangerously poor swimming ability is plot-significant and touched upon at several points.
• Supporting Protagonist: Despite being a protagonist, most of the series focuses on the boys and their backstories.
• The Un-Reveal: It's never been revealed who Yui's biological parents are, why they gave her up for adoption and if they're still alive or not.
• Token Human: She is the only human with a sprite in the whole of the series.
• Unlucky Everydude: Her father moved abroad and she is forced to live in a mansion with six mysterious vampires.

Sakamaki Brothers

Shu Sakamaki

Voiced by: Kosuke Toriumi (Japanese), Ty Mahany (English), Oscar López (Mexican Spanish), Lucas Gama (Portuguese)

The eldest son. He's intelligent, but a lack of motivation caused him to have to repeat a grade. He particularly hates being dragged into troublesome things.

---

• Adaptational Nice Guy: Relatively speaking in the VNs. While Shu's "you make the first move" approach was established from the start, in the early audio dramas he is also very into knife play.
• Aloof Big Brother: Despite being the eldest Sakamaki sibling he rarely takes leadership or shows care for his younger brothers - most of his interactions with them involve complaining about how loud and annoying they are.
• Black Sheep: He is the presumed family heir, but he resists the role by taking on as little responsibility as he possibly can.
• Brilliant, but Lazy: Shu has very little motivation to apply himself to anything, but he's far more intelligent and perceptive than he cares to let on.
• Cain and Abel: Reiji resents Shu intensely because he is the first-born and presumptive heir, and nothing Reiji can do will ever change that fact. Shu knows this and passively tolerates Reiji's frequent insults.
• Coat Cape: He drapes his uniform jacket over his shoulders without properly putting it on.
• Covert Pervert: Yui initially thinks that she might be in less danger from someone as checked-out as Shu, but that is not exactly the case. His behavior is more vexing than it is cruel; he never lets an opportunity to tease her pass him by, and is quite good at creating situations where she overextends herself on his behalf so he can tease her about lusting after him.
• Doom Magnet: He thinks he will bring misfortune on anyone whom he grows attached to after losing Edgar to the fire as a boy. Even in More,Blood, where he knows from square one that Reiji started the fire, he insists on taking all the blame himself.
• Elegant Classical Musician: Plays the violin and is very charismatic, though all the gifts and love letters he gets from girls at school are a nuisance to him.
• Extreme Doormat: He has a low regard for his own well-being and allows people to use him as a literal punching bag. At one point he is randomly attacked by anonymous human hooligans that he could easily overpower, but he does nothing to defend himself. He behaves the same way when Yuma attacks him in More,Blood, but since Yuma is the focus of his Guilt Complex, his self-denial goes into overdrive to the point that he surrenders Yui to him. Even Yuma is unnerved by this - not that he turns down the offer, though.
• Freudian Excuse: The reason why Shu is such a Kuudere is because Edgar, his first friend, died during a fire after trying to save his family. After that traumatic experience, Shu secluded himself from the rest of the world.
• Headphones Equal Isolation: He is always seen with his MP3 player attached to a wire that which is wrapped around his neck and with the earphones always in his ears, and Yui can't tell when he is ignoring her from when he is spacing out.
• Held Back in School: He's 19 and is still in his third year of high school.
• Jerk with a Heart of Gold: While he's aloof and as rude to Yui as his brothers are, Shu doesn't do anything outright cruel to her.
• My Greatest Failure: Edgar was Shu's first friend and the first one who treated him as a person. Unfortunately, he died in a fire (later revealed to be caused by Reiji). The trauma was so great that Shu decided not to attach himself to anyone or anything again. When he meets Yui, he brushes her off at first, afraid to attach to someone else. He later comes to see Yui as his My Greatest Second Chance, at least in his route.
• NEET: This is Yuma's nickname for Shu, although strictly speaking it is inaccurate. It is impossible to be both a NEET and a student. On the other hand, Shu is only a student because he was held back and he barely participates in school.
• Older Than They Look: Despite being the eldest, he looks slightly more youthful than Reiji. In the manga Yui asked him if he's Reiji's little brother. Justified since vampires with later birthdays are the elder brother.
• Personality Blood Types: Type AB; purportedly AB people seem to have a "split-personality". This reflects the dramatically different and far more engaged side of himself that he shows Yui.
• Real Men Hate Sugar: Downplayed; he honestly prefers savory foods over sweet ones.
• Sleepyhead: He sleeps a lot and yet he is always tired. He verges on Sleepy Depressive given all the aspects of his life that he is trying to avoid, and he can fall asleep practically anywhere.
• Strong Family Resemblance: He inherited his blond hair and blue eyes from his mother.
• Sugar-and-Ice Personality: The emotions were always there, deep down; he just never had anyone to bring them out because nobody except for Edgar, who died shortly after, has ever bothered to treat him like a person instead of the family heir.
• Symbolic Serene Submersion: The representative image of Shu is him alseep in a bath, fully dressed. Yui is immediately alarmed to find him like this since it seems like suicidal behavior, but Shu couldn't die this way even if he wanted to. Vampires don't asphyxiate, after all.
• Trademark Favorite Food: Rare steak. It's one of the few things Yui manages to get him out in public for.
• Used to Be a Sweet Kid: He was openly kind and extroverted as a child, but he came to view these qualities as a liability to be suppressed.
• Why Did It Have to Be Snakes?: Shu has pyrophobia (fear of fire) as a result of his childhood trauma. It is most pronounced in the first VN, where he has a panic attack after observing a burning building. Subsequent VNs dial it down so he dislikes fire, but no longer has a debilitating phobia.

Reiji Sakamaki

Voiced by: Katsuyuki Konishi (Japanese), David Wald (English), Manuel Perez (Mexican Spanish), Rodrigo Nanal (Portuguese)

The neurotic second son. He treats both the laws of the Sakamaki family and his own standards as important and he forces those around him to abide by those rules. He has a polite manner of speech, but the actual content of what he says is harsh.

---

• Cain and Abel: Ever since they were little, Reiji was envious of the attention that Shu got from their mother, Beatrix, and those feelings intensified into a Inferiority Superiority Complex. Reiji disapproves of everything Shu does, and goes out of his way to make sure nothing works out well for him.
• Challenge Seeker: In his More,Blood route, he is almost giddy about the prospect of investigating the motives of the Mukami brothers. It's the most interesting thing to cross his path in a long time and an opportunity to dust off his Sherlock Scan, plus it might even give him the means to achieve his secret ambition: to put his whole family out of his misery.
• Conspicuous Gloves: Wears a white one on his right hand in a touch of Fashionable Asymmetry.
• Control Freak: He values rules and demands that they are followed by others, waging a unwinnable one-man war against the selfishness and dysfunctionality of the Sakamaki family. After all, he is dysfunctional himself, to say nothing of how he is Shu's Freudian Excuse, and doesn't stand a chance of keeping them in line with something as nebulous as family honor. Even he has doubts about whether Karlheinz cares at all about his efforts to honor him.
• Deadpan Snarker: Despite how rigid he may seem, he still has a sense of humor (albeit a dry one).
• Fetishized Abuser: As the representative Kichiku Megane for the franchise, he is cold, classy, exacting, and controlling toward the heroine. The visual novels actually make him nastier than the early audio dramas by giving him one of the the classic BDSM signifiers - Whip of Dominance.
• Four Eyes, Zero Soul: The only one of his brothers to wear glasses. He, just like the rest of his brothers, is an extreme sadist (but also has a surprising, extremely masochistic side if triggered right). His particular phrase is schadenfreude (German for "happiness in the misfortune of others"). Sometimes he does or says something in order to get a reaction that amuses him.
• Insufferable Genius: Reiji will call anyone an idiot if he finds what they do and/or say to be stupid.
• Neat Freak: He cleans the mansion because no one else will.
• Mad Scientist: Specifically the mad chemist variety. He is the go-to character for potions and poisons, but what really drives home the mad part is that his main chemistry goal, at least in the beginning, is to create a drug to bring his mother back to life in order to kill her again. His drug development process is also one of his favorite ways to torment Yui. For example, telling her he just completed a poison, forcing her to drink it, then revealing that it was tea all along.
• Madden Into Misanthropy: He drove himself to this through his pride and vindictive tendencies. He measures everyone against an ideal that not even he can live up to, and inevitably finds everyone wanting. He knows that Shu has powers he can't match and hates him for squandering it. By the same token, his pedestal for Karlheinz is broken and he claims to have tried to kill him many times over. More,Blood recontextualizes his murder of his mother as an oblique attempt to kill Karlheinz that failed - he was supposed visit Beatrix that night, but he never showed.
• The Perfectionist: His insistence on perfection is insufferable and sometimes terrifying. Insufferable in that he holds Yui to account for being 3 seconds late to meet him. Terrifying in that he is disappointed about how things went when he had his mother murdered to the point that he is trying to enact a do-over.
• Real Men Wear Pink: Reiji loves to collect tea sets and dinnerware.
• Rules Lawyer: Shown by how he values rules, Reiji is a strict person towards both himself and those around him.
• Smart People Play Chess: As befits his position as The Smart Guy, he is good at chess and wins against Yui every time they play.
• Soft-Spoken Sadist: Even though he has a polite, sophisticated way of speaking (which the creators describe to be "butler-like"), his words tend to come with a biting edge even when he is at his calmest. He usually maintains this polite tone even when he is in a towering rage.
• Stoic Spectacles: The only one of his brothers to wear glasses and is the least openly emotional among them.
• Strong Family Resemblance: Cordelia tells him that if he weren't so stiff, he would look just like his father from back when she first met him. She even says their eyes are similar.
• Tall, Dark, and Handsome: Dark-haired, sharp-dressed, and one of the tallest characters in the series. The only love interest that's taller than him is Yuma.
• Tea Is Classy: Reiji enjoys English tea in his fancy tea sets. He even states that he prefers tea rather than drinking Yui’s blood. He changes his mind at the end of his route, in Reiji’s Good End.
• Trademark Favorite Food: He really likes spaghetti carbonara.
• Tsundere: A normally spiky type, of course, and it is nearly impossible to get him to flip to sweet. It takes something like his prospective bride getting possessed by the spirit of one of his father's dead wives so that she is potentially lost to him forever to wring a bit of honest kindness out of him.
• Turn Out Like His Father: In his Dark Fate good ending, Reiji fully carries out Karlheinz' plan - including the genocide part. Of all the brothers he's the only one to intentionally do so.
• Younger Than They Look: Yui mistook him for a butler at first. When she asked Shu if Reiji's his older brother, she was surprised that Shu admitted he's the eldest one.

Laito Sakamaki

Voiced by: Daisuke Hirakawa (Japanese), Blake Shepard (English), Hugo Nuñez (Mexican Spanish), Dláigelles Riba (Portuguese)

The first-born of the triplets, but considered the youngest. A self-professed sexual deviant; he enjoys provoking negative reactions in those around him, and his abnormal behavior stands out.

---

• Alliterative Family: Downplayed. This only applies to the triplet brothers. The last syllable of each their names is -to.
• Evil Redhead: He only has red hair in the TV series, but he is a sadistic hedonist nonetheless.
• Deus ex Machina: Yui kills herself in Laito's More,Blood route, but Karlheinz makes a positive intervention in the lives of his children for once and brings her back to life. He's not pleased to have to go so far, but nothing with Laito is ever easy.
• The Hedonist: Has a talent for finding delight in whatever situation he finds himself in, no matter how inappropriate or twisted the situation may be.
• Hidden Depths: Despite his pleasure-seeking behavior, Laito is good at interpreting peoples' motives.
• Hormone-Addled Teenager: He has been suspended multiple times for fooling around with girls at school.
• Knowledge Broker: Laito's stories tend to involve secrets because he makes it his business to be in the know. His route in the first VN is the other route where Yui learns her father is a vampire hunter. He also tells her how the church sold her out and is very up-front with her about how she's turning into a vampire. It turns out he has a network of familiars spying on the whole cast, and one of his bad endings reveals that his familiars are what's left of the failed sacrificial brides.
• Ladykiller in Love: Given his (almost) unsalvagably warped and harmful understanding of relationships with women, "love" is a word he uses very casually and assigns very little value to. It takes more than one story arc for him to get past this - he does not truly love Yui in any of his outcomes in the first visual novel. His More,Blood route distresses him to the point of role-reversal - In the first VN, Yui becomes so afraid of Laito's influence on her that she wants to die; in More,Blood Yui's effect over Laito drives him to attempt suicide.
• Lovable Sex Maniac: In the VNs he tends to come off as this trope in other character's routes, since there is no follow-through on his blatant flirting and provocative behavior.
• Leg Focus: If there was any doubt after all the times he bites Yui's thighs, supplemental material makes it clear that Laito is a leg man. He's certainly not the only love interest that bites her legs, but he is the only love interest to have several illustrations across multiple VNs depicting it.
• Naked Apron: He gets very excited upon finding Yui preparing a meal while wearing an apron, because he's never actually seen anyone wear one, and it means this trope is just a few fragile articles of clothing away from being a reality.
• Parental Incest: The reason why Laito is an emotional disaster zone. Cordelia was a profoundly selfish person who only knew how to interact with people who could give her things. Her sons were no exception. She turned to Laito for sexual gratification, and he came to understand love not as an emotional state but as an act undertaken for power and pleasure. When Karlheinz found out about their relationship, he imprisoned Laito in the basement dungeon. Cordelia cut it off with Laito in the cruelest way possible - she had sex with Richter, his uncle, in front of the cell where he was being held.
• Personality Blood Types: The triplets are all type O, the leadership blood type. It reflects Laito's confidence and intuitive nature, and also his selfishness.
• Replacement Goldfish: Gets uncomfortably close to this in the first VN when he tests Yui to figure out how Cordelia-like she is.
• Spell My Name With An S: Some dubs address him as Raito or Light (due to another Light with same name pronunciation), but supplementary materials confirm his name is Laito.
• Subterfuge Judo: When Richter shows up at the Sakamaki manor looking for Yui, both he and Laito conceal their true intentions from each other while maintaining the thinnest veneer of civility. While Laito doesn't fully know what Richter is up to, the fact that he is interested in Yui confirms his suspicions that she is connected to Cordelia in some way.
• Tears of Blood: Sheds some in memory of Cordelia in the first VN. This may be Early-Installment Weirdness since he's the only one to do so, and when he cries in his More,Blood route, not only are his tears of the standard type, but also he reacts as if he has no first-hand experience with crying.
• Trademark Favorite Food: Macarons.
• Vampires Are Sex Gods: And none more aggressively so than Laito. It seems like there's nothing he won't try in the bedroom, to the point of wanting to share Yui with others and getting off watching other men prey on her, but then he becomes possessive and jealous and punishes her for it. He also doesn't mind if people watch when he is messing with Yui.
• Wants to Be Hated: He manages his trauma by embracing its effect on him. If he's a man-whore with his mind in the gutter by choice, he controls it and it can't be used against him. Getting called a pervert or a voyeur does not offend him - he counts them as compliments. There is no name Yui can call him, no protest she can raise, that won't just egg him on. She knees him in the stomach at one point and he's right back to seduction in a matter of moments.
• Who Wants to Live Forever?: He frequently mentions that vampires view death as a welcome thing. Because he's already tired of life. Falling in love with a mortal doesn't make him feel any better about it.
• Why Did It Have to Be Snakes?: He is scared of bugs and creepy-crawlies.

Kanato Sakamaki

Voiced by: Yūki Kaji (Japanese), Corey Hartzog (English), Karla Vega (Mexican Spanish), Francisco Freitas (Portuguese)

The middle child of the triplets. He is prone to both crying fits and tantrums, and his boyish looks belie how threatening he is. Fortunately he is easily appeased by sweets, which he loves.

---

• Alliterative Family: Downplayed. This only applies to the triplet brothers. The last syllable of each of their names is -to.
• Ax-Crazy: He is liable to blow minor discomforts or slights into major screaming tantrums, which can get violent or even murderous.
• Companion Cube: Kanato is rarely seen without his stuffed bear, Teddy, and initially Teddy is the only...person? he addresses with any kindness or affection.
• Creepy Shadowed Undereyes: He has a pale complexion and sunken eyes to match his morbid personality.
• Crocodile Tears: More often than not his crying fits are calculated to either repulse his brothers or draw Yui's sympathy, and as soon as he gets what he wants his mood normalizes.
• Curtains Match the Windows: Light purple hair and light purple eyes.
• Does Not Like Spam: If it's not sweet, Kanato won't eat it. He hates anything spicy or bitter.
• Dude, She's Like in a Coma: Most love interests stop drinking from Yui when she passes out, which occurs frequently considering the blood loss involved. Not Kanato, though. He likes it when she's unconscious.
• Extreme Mêlée Revenge: In Dark Fate, Kanato endures beatings from Shin and is forced to watch Carla suck Yui's blood right in front of him, but he takes brutal revenge on Shin for it. It's almost as messy of a kill as Shu's manservant end in the first VN. Both involve Head Crushing, but if anything distinguishes these two events, it's that Kanato thinks nothing of fighting dirty.
• I Just Want to Be Loved: What's at the core of his issues. Kanato's mother treated him like a songbird or an ornament, and that's when she bothered to remember he existed. Even when little Kanato hurt himself to get her attention, she ignored him. This left him unbearably lonely, and filled with rage that he takes out on everyone around him.
• Kitsch Collection: Teddie is not his only stuffed bear - not by a long shot. Kanato's bedroom is full of plushies. This does not make him any less creepy.
• Living Doll Collector: Has a room full of disturbingly realistic wax dolls that he made himself. They used to be people of course, but their identities vary depending on the medium. In the visual novels, they were Cordelia's personal servants and/or former lovers and she encouraged Kanato to kill them and fashion them into dolls when she grew tired of them. In the anime they are Yui's failed predecessors in the role of the sacrificial bride. (The VN reveals an even more dreadful fate for the fallen brides in Laito's route.)
  • This is also the main way that Kanato's yandere tendencies manifest and the main reason that his good ending in the first VN is not especially happy. Through a combination of gaslighting and narcotics, he shrinks Yui's world down so that she no longer cares about or remembers anything besides him. But he does still marry her after taking his father's throne, so...real mixed bag.
• Masochist's Meal: In his route, he forces Yui to eat disgusting food such as seaweed and raw liver, because it would make her blood taste better.
• Memento Macguffin: Teddie was originally a gift for Cordelia - she wasn't impressed with it and passed it on to Kanato. He became attached to the stuffed bear right away, but Teddie gained extra significance for him after her death, when he hid a vial of Cordelia's ashes inside it. Teddie serves as a kind of stand-in for her that he can keep to himself.
• Mood-Swinger: Like nothing else! His baseline is a state of vague annoyance, but he never stays that way long. He cycles from enraged screaming, to sobbing, to giggling with bewildering speed.
• Nightmare Fetishist: Kanato was on his own wavelength even when he was little, which no doubt contributed to the very alarming lessons he took away from his relationship with his mother and subsequent participation in her murder: the only way to hold on to your loved ones is to kill them, or to damage them in some way so they can never leave. To him death is beautiful, cemetaries are soothing, and corpses are precious.
• Older Than They Look: He is actually the same age as Ayato and Laito (since they are triplets) and older than Subaru.
• Psychopathic Manchild: Many characters in this series have issues with mood regulation, but Kanato is the high bar. If something upsets him he will assign blame to someone else, and scream, or cry, (or both,) until they either pacify him or leave, and either outcome suits him in most cases. Unless the person he choses to blame is Yui, because he can overpower Yui. Her only hope is to try improve his mood. And the more attached to her he becomes, the more likely she is to be a focal point for his rage.
• Replacement Goldfish: In the first VN he burns Teddie himself. He doesn't need him anymore...because he has Yui.
• Sweet Tooth: He really likes sweets and they are one of the very few things that can prevent one of his violent fits.
• This Is Unforgivable!: He uses variations on this phrase so frequently that it nearly loses its power as an ultimatum, but when he really means it, he means it with Killing Intent.
• Token Mini-Moe: He is the boyish love interest - the shortest of the boys, he is quick to cry and seems innocent and vulnerable. Yui starts off trying to take a "big sister" approach with him, but this quickly proves to be a mistake. He hates being underestimated.
• Trademark Favorite Food: His favorite dessert is raspberry pudding, but he likes anything sweet in general.
• "Well Done, Son" Guy: As a child, Kanato craved his mother's attention and would self harm just to get it, though these efforts were largely in vain. Kanato did love Cordelia as a child; however, this never reached her because she shows zero interest in him aside from his singing.
• Yandere: Kanato can freely be categorized as a "yandere type". Once he forms an attachment to Yui he clearly cares about her deeply and is very affectionate to her, but she is also the only thing he cares about. Everything else in the world is an impediment to their relationship. Kanato is childish but overly possessive and even if he's not always thinking clearly, he must decide the future not only for himself but also for the heroine.

Ayato Sakamaki

Voiced by: Hikaru Midorikawa (Japanese), Chris Patton (English), Ricardo Bautista (Mexican Spanish), Fabrício Rinaldi (Portuguese)

The last-born of the triplets, but considered the eldest. He insists and seeks to prove that out of all the brothers he is the best and the strongest. He loves causing mischief and stirs up a lot of trouble.

---

• Abusive Parents: His mother Cordelia forced him to study really hard (often forbidding him to play) and instead of praising his efforts, she would often belittle him and physically abuse him for any perceived failure, telling him that if he wasn't the best, he had no value. She punished him by throwing him in a lake, despite his inability to swim, and would watch as he struggled and begged her to save him.
• Alliterative Family: Downplayed. Like the other triplets, the last syllable of his name is -to.
• All Men Are Perverts: To a lesser extent than Laito. According to a character interview, the first place he checks when looking at a girl are her breasts.
• Animal Motifs: Foxes, which he's cunning as.
• Asleep in Class: He and Yui are in the same class, although he usually sleeps through lessons. There are never any repercussions for this.
• Because You Were Nice to Me: In his route, Ayato falls in love with Yui because of her unwavering kindness to him. He particularly appreciates her small affectionate gestures - he didn't know that he liked having his hair stroked before she came along.
• Big Eater: Being a Hot-Blooded sort, Ayato has a big appetite. When it comes to human food the only thing he'll eat is his favorite, takoyaki, but he'll eat a lot of it. He overindulges on vampire food also, and Yui suffers pretty intense anemia on his routes.
• Cannot Spit It Out: Ayato has a hard time expressing his feelings, sometimes to the point where he'd sooner break Yui's heart than admit that he cares about her.
• Commitment Issues: Seen in the More,Blood VN. The character motivations are altered enough in this version that Ayato does not view Yui as a means of being the best, but an impediment to it. As a boy, he could tell that Cordelia brought pain on herself due to unrequited love and vented it on him and his brothers. He identified romantic attachment itself as the source of the problem, and refuses to acknowledge that he has feelings for Yui.
• Evil Redhead: Ayato's red hair can be taken as a sign of danger - he is quite the rebel and has a passion for torture devices. He keeps an Iron Maiden in his room which he uses instead of a bed (the spikes were removed).
• Fashionable Asymmetry: The right pant leg of his school uniform is rolled up to his knee.
• Family Eye Resemblance: His green eyes are similar to Cordelia’s and Laito's.
• Fiery Redhead: When Ayato isn't being a sadistic jerk, he's outgoing, boisterous, and shows a passionate side.
• I Will Find You: Searching for the heroine is a persistent theme with him, though often as low-key as tracking her around the house. If she's really missing, he will not stop looking for her - to the point that his brothers may lock him up so he won't tear the Sakamaki manor apart out of frustration.
• Implied Love Interest: All but stated to be Yui's canon partner, given he's front and center on almost every cover and is depicted with her the most often.
• The Nicknamer: Besides his infamous nickname for Yui, he has dismissive nicknames for everyone else in the house too.
• Pride: He has a lot of it. Ayato is the type who always brags about himself; sometimes commanding everyone to call him "Ayato-sama".
• Significant Green-Eyed Redhead: He is one of the main characters and happens to have red hair with green eyes.
• Silver Spoon Troublemaker: He is the Sakamaki family practical joker and his pranks range from innocuous to highly threatening. The worst repercussions he faces are sour looks from his brothers or Yui avoiding him for little while - and whether through sneakiness or impunity, he seems to face zero consequences for anything he gets up to at school.
• Stock Shōnen Hero: Spiky haired, Book Dumb, and Hot-Blooded, he never backs down from a challenge and seeks to be the best. In the later VNs he even gets the Power of Friendship treatment, with all of his brothers coming to his aid in dangerous situations.
• Trademark Favorite Food: Loves takoyaki, and some of the funnier moments in the story involve quarrels among the brothers over these snacks.
• Virginity Flag: He deduces that Yui is a virgin based on her Sacred First Kiss fretting, and is very pleased. And ready to go right there in the school storeroom while classes are going on. Reiji lives up to his reputation and puts in an appearance to cockblock.

Subaru Sakamaki

Voiced by: Takashi Kondo (Japanese), Josh Grelle (English), Pablo Mejia (Mexican Spanish), Douglas Guedes (Portuguese)

The youngest son. He is gruff, easily provoked, and avoids the company of others. He takes a rebellious attitude towards his older brothers, who find him gloomy and troublesome.

---

• Archnemesis Dad: The Sakamaki brothers almost all hate their father, but it's extra personal for Subaru, who intends to kill Karlheinz to honor his mother's request.
• The Baby of the Bunch: Subaru is the sixth and youngest son of the Sakamaki household, and he is a little awkward and less practiced at concealing his feelings than his older brothers.
• Child by Rape: Subaru assumes that he is this based on the tortured reactions his mother has to his father's presence. However, she is delirious most of the time and Subaru doesn't know the whole story. It's eventually revealed that she loved Karlheinz, married him willingly, and her realization that he didn't love her in return was what drove her mad.
• Hair-Trigger Temper: Can get angry very easily, and when he is in a bad mood he makes for terrible company.
• Ineffectual Loner: He rarely bothers being around company and in fact, thinks that everyone is better off without him.
• Internalized Categorism: Subaru thinks that there is something fundamentally wrong with him based on his mother's ravings about her own lost purity.
• Japanese Delinquents: Has some elements of this in his rough speech and disheveled clothes - and of course he likes to fight and seeks to intimidate others by breaking things.
• Jerk with a Heart of Gold: He can be easily swayed into violent behavior when provoked (even if just a little bit) but shows more empathy towards Yui than his other brothers.
• Momma's Boy: As a child he cared for his mother’s well-being immensely although Subaru suffered the brunt of her mental and verbal abuse, he can only blame and despise Karlheinz for her Sanity Slippage.
• Personality Blood Types: He is a type A, whose traits include being kind and responsible, but tense and uptight.
• Plain Palate: Subaru doesn't have a favorite food as an indicator of how austere his life was while looking after his mother. He doesn't have any hobbies, either.
• Properly Paranoid: Subaru's experiences with his mother give him a different perspective on Karlheinz' intentions for the family. He knows that everyone in the family is some sort of unwitting pawn, and connects the dots between Cordelia's missing heart and Yui's recurring chest pain. He avoids sucking her blood from then on because he doesn't want to her to end up in Karlheinz' clutches like the rest of them.
• Punch a Wall: His signature move. If something sets him off, he takes it out on the drywall or the furniture - and it doesn't take much to do it.
• Red Eyes, Take Warning: He inherited his mother's red eyes, but unlike her, he can use them to enhance the scariness of Slasher Smiles.
• Sour Outside, Sad Inside: He lashes out to intimidate people into leaving him alone. He treats Yui as cruelly as his brothers at first, but he is actually being over-the-top mean in hopes that she will run away from the Sakamaki manor altogether and avoid ending up like his mother.
• Strong Family Resemblance: Has his mother's hair and eyes.
• The Tease: He starts to fancy Yui for more than just her blood pretty early on, but doesn't push it because he is aware that sex would be a point of no return for her. He's not above making it clear that he wants her, though.
• There Was a Door: Subaru's obligatory Shower of Awkward scene involves him Kool-aid Man-ing through the bathroom wall just as Yui is getting out of the bath. And why does he do this? Because Ayato was about to pitch a fit at him about eating his takoyaki and he didn't want to deal with it. He at least keeps Ayato from also walking in on Yui while she's changing.
• Token Good Teammate: Among his brothers. He's the only one to actually try to help Yui escape from them.
• Tsundere: As usual, a default-tsun type, but he shows his sweet side more frequently than the other tsundere love interests. Yui isn't the only one who sees it - his brothers, particularly Laito, also know he's more bark than bite and like to tease him about it.
• White Hair, Black Heart: Downplayed Trope. While he is a white-haired pretty boy and his very pronounced tsun mode leads to undeniable jerkass behavior, he is the most naturally empathetic of the Sakamaki brothers.
• Younger Than They Look: He is the youngest of the Sakamaki siblings, but looks about the same age as Ayato or Laito - and he definitely seems older than Kanato.

Mukami Brothers

Ruki Mukami

Voiced by: Takahiro Sakurai (Japanese), Adam Gibbs (English)

The eldest of the Mukami brothers. A well-spoken manipulator whose keen awareness keeps him one step ahead; he seldom gets personally involved and leaves the dirty work to his brothers.

---

• Adaptation Dye-Job: Ruki's Curtains Match the Windows, but the colors vary. In the audio dramas and visual novels both his eyes and hair are gray. The anime adds a blue tint to them.
• Animal Motifs: He compares himself to the deceptive serpent in the Garden of Eden who leads Eve astray from her true purpose. He also has Wise Serpent traits - he is calm, intelligent, and a dangerous opponent.
• Arc Words: Calling people "livestock" has been a through-line in his life. He belittles Yui this way so often that it seems like he can't help but bring it up. But she is far from the first person he ever insulted this way, and others have called him livestock too.
• Aristocrats Are Evil: The Mukami brothers resent unearned wealth and privilege, and accuse the Sakamakis of this trope, but Ruki actually embodied it as a boy. He grew up a Blue Blood, and was cruel and belittling to the family servants because he was so convinced of his superiority over them.
• Badass Bookworm: He is visually associated with books and often reads as a pastime. While he isn't a top choice when it comes to ass-kicking, he can manage it if his Zero drama CD is any indication.
• Bunker Woman: He forces Yui into this role in a cold-blooded attempt to keep his plan from falling apart. While in the anime he locks her in a storeroom and regrets it right away, in the VN he keeps her in an underground dungeon for a much longer period of time and manages his guilt over it much more effectively. In either case, as soon as his sympathy for Yui outweighs his ambition, Ayato appears to steal her back.
• Conflicting Loyalty: When he concludes that he cannot become Adam, his logical next move - the move a faithful servant of Karlheinz would choose - would be to free Yui to seek another suitor. He tries...but he can't bring himself to turn away.
• The Cynic: Ruki assumes everyone is motivated by self-interest. This suits him fine, since if all relationships are transactional he never has to make himself vulnerable. He reacts badly to Yui's attempts to show him kindness, calls her a hypocrite for it, and accuses her of ulterior motives on a regular basis.
• Dark and Troubled Past: He and his brothers went through a great deal of pain and deprivation together, but Ruki is different from the others in that he was once one of the entitled rich boys they profess to hate. And he rivaled any of the Sakamakis in terms of cruelty, even as a pre-teen. He got a taste of his own medicine after his noble house was suddenly brought to ruin, and the commoners he mistreated turned the tables on him for all the cruel things he had done to them.
• Does Not Like Spam: He hates strong-flavored food and drinks.
• Don't You Dare Pity Me!: He loses his cool when he realizes Yui feels sorry for him, and shuts down conversations about his past to try to deny her opportunities to express sympathy.
• Faux Affably Evil: Despite his calm nature and logic-driven approach to interacting with others, a barely concealed sense of brutality can be felt in his spoken words.
• Heel Realization: He has a decisive one in Dark Fate after his attempts to push Yui away work too well and she accepts the attentions of another man. He gets unreasonably angry at her, causing her to run away from him. He eventually kneels at her feet, begs for her forgiveness, and is sweet to her for the rest of the route.
• The Leader: Ruki is the leader of the Mukamis, and his three brothers always heed his orders. A mastermind-type; he is skilled at analyzing the strengths of his allies and matching them against the weaknesses of his adversaries.
• Living Is More than Surviving: He has a very dark perspective on this - in his experience, life without any freedom is simply a slow death. He uses this concept to justify killing a kitten that Yui brings home, and seems so certain that it was a mercy that Yui can't even bring herself to be angry at him.
• Mark of Shame: He was branded on his back like 'livestock' as punishment for trying to run away from the orphanage.
• Orphanage of Fear: He ended up in one after a stint as a Street Urchin. Other orphans there bullied him brutally because he carried himself like a Blue Blood, and the only friends he made there were Kou, Yuma, and Azusa. They devised a plan to escape and it was successful, at first. The orphanage staff managed to recapture them. The head of the orphanage, recognizing Ruki as the mastermind, branded him with a fire poker. He was resigned to dying from his injuries rather than go on this way when Karlheinz appeared, and offered him a new life as a vampire.
• Parental Abandonment: When his father became bankrupt, his mother ran off with her secret lover, and his father hanged himself.
• Past Experience Nightmare: His regular trauma-induced nightmares are a real Spanner in the Works for his attempts to keep Yui from feeling sympathy for him.
• Personality Blood Types: Type AB to match his logical and analytical personality.
• Put Them All Out of My Misery: Ruki's bad endings in More,Blood. Driven over the edge by a lifetime of being denied the things he wants most, he either massacres Yui's entire class excluding her, but including Ayato, or murders all of the Sakamaki brothers while they are asleep. In both cases, Karlheinz puts him down.
• The Smart Guy: The "brains" of the Mukami family and their leader. Despite his status as a Manipulative Bastard, Ayato tends to mock him for his sometimes forced intellectual manners.
• Smug Smiler: He always has an intimidating smirk on his face matched with a calm tone.
• Tall, Dark, and Handsome: Has dark hair, gentlemanly manners, and a cool, aloof attitude.
• Trademark Favorite Food: Soup. He responds positively when Yui prepares soup for him, even when she accidentally spills some on him. He does make her lick it off of him, though.
• Tragic Keepsake: The book he carries is a memento from his father.

Kou Mukami

Voiced by: Ryōhei Kimura (Japanese), Bryson Baugus (English)

The outgoing second son who is playing the role of an idol. While he is very moody and self-centered, his devilish charm seems to appeal to people and he's quite popular.

---

• Bait the Dog: He has a terrible genius for this. In fact, it's his opening move in his More,Blood storyline - he gives Yui a big bouquet of roses, only to tear them to bits when she rejects his advances. In the VN this is only the start of the scene, and he gets much meaner after that.
• Beware the Mind Reader: Kou occasionally answers aloud questions questions that Yui asks in her internal monologue. Yui notes that sometimes she feels like he can see straight through her, and she's right. His ability is a major contributor to how difficult he is to deal with.
• Big Eater: Vampires must not gain weight, because he can eat a dinner for four on his own. And he'll talk with his mouth full while he does it, no matter how often Ruki scolds him for it.
• Bitch in Sheep's Clothing: Although he seems friendly at first, he is a hypocritical sadist who belittles people. This is its Establishing Character Moment. He is also extremely unstable and Yui is always at his mercy.
• The Charmer: As an idol, he has many fans, including a number of girls who attend Ryoutei Academy. They're lucky they don't know how he really feels about them.
• Did You Actually Believe...?: Early on, he takes advantage of Yui's earnestness to put her in humiliating situations. He'll twist the knife by laughingly saying some permutation of this phrase, implying that she is too ordinary and plain to deserve the attention of a handsome, talented idol.
• Dark and Troubled Past: Kou was abandoned by his parents and ended up in an Orphanage of Fear. Due to his angelic looks, the orphanage regularly sent him to a club where aristocrats tortured children for their own amusement. He eventually decided to disfigure himself, gouging out his right eye in hopes of making himself less appealing. It didn't work since they preferred him badly injured, and he was nearly Driven to Suicide after admitting to himself that his life was hell.
• The Fake Cutie: Kou is two-faced. He draws people in with fun, Keet-like behavior, and then deliberately hurts them once he has them on the hook.
• Genius Slob: While not the typical smart guy, Kou excels at a distinctive skill-set - he is a sanitized version of a high-class call boy. He entertains, he charms, and he is generous with his favors when it suits his objectives. But that artfully tousled hair? There's actually nothing artful about it - he just has gorgeous bed-head. His table manners are heartbreakingly bad - in a callback to the squalor of his early childhood, he eats even messy foods like cake with his hands. He is fascinated by Yui's domesticity and can barely disguise his amazement when she sews a button back onto his jacket.
• Glass Eye: When he was first given his new eye, he describes it as a jewel.
• Hair-Trigger Temper: His foil in More,Blood is Subaru, and they share this trait, but with inverse expressions to the other. While Subaru is more bark than bite, Kou is the opposite. He bypasses Yui's guard with his charm and breezy attitude, only to abruptly and violently flip on her when she stumbles onto one of his triggers.
• Idol Singer: Does this professionally in the human world, and in his More,Blood route he is disappointed that Yui doesn't recognize him.
• Love Hungry: Kou doesn't know how to identify love, but he does know that love is key to Karlheinz's plan and he is under pressure from Ruki to deliver results. So he fabricates Rescue Romance situations, putting himself in danger so that Yui feels she has no choice but to intervene. He insists that her actions prove that she loves him, but whatever sign the Mukami brothers are looking for, they don't see it.
• Magical Eye: His right eye can see into people's hearts and he can tell if they're lying.
• Orphanage of Fear: He ends up in the same one as Ruki, Yuma, and Azusa. Initially he is pleased to be there because he recieves special treatment from the staff, but soon discovers that he is a lamb being led to the slaughter. See Ruki's entry for details on their escape.
• Parental Abandonment: He was abandoned in a sewer at a very young age.
• Personality Blood Types: Type B, to match with his outgoing persona. He also has the dark side of the type B personality - selfishness and erratic behavior - in spades.
• Safety in Indifference: His miserable childhood left him with no frame of reference for love or affection. This never bothered him...until Yui comes along.
• Sex Slave: He was so in-demand during his childhood appearances at the aristocrat sadist club that any wounds he received from previous encounters never healed. The story does not depict a sexual element to what they did to him (that's the sort of material not even Diabolik Lovers can get past the radar) but sadism is sexual in this franchise, so the trope is implied.
• Silent Treatment: He will shun people and acting like they aren't even present when he is really upset with them. He does this to Yui in one of his More,Blood bad endings, and in Ruki's Dark Fate route he does it to Ruki.
• So Beautiful, It's a Curse: His appearance saved him from becoming a war casualty, but delivered him into circumstances so bad that getting shot in the street would be kinder. His beauty attracts the worst possible people, but being dirty or slovenly hasn't made any difference and his attempt to tarnish it himself backfired.
• Trademark Favorite Food: Vongole Bianco pasta. Yui cooks it for him, unaware that it is his favorite, and he is so overjoyed that he insists on seconds. And thirds. And fourths. And you don't say "no" to Kou if you know what's good for you.

Yuma Mukami

Voiced by: Tatsuhisa Suzuki (Japanese), Andrew Love (English)

The third brother and the "muscle" of the group. He has a huge body, with a voice and attitude to match. His rough manner of speech and laid-back attitude give him a friendly air, but he reacts violently on impulse when provoked.

---

• Animal Theme Naming: After developing amnesia as a child, he goes by the nickname "Bear" on account of his stature.
• Bruiser with a Soft Center: He is undeniably intimidating and has the brawn to back up his threats, but around his friends and family he shows a nurturing and protective side.
• Death by Origin Story: He had good people in his life before meeting his brothers, if only temporarily. His parents were well-meaning people, and he lost his memory in a futile attempt to save their lives. Later, his gang boss, Lucks, was an inspirational figure in his life and encouraged him to work toward a more just world. Lucks was killed on the verge of setting his plans in motion, leaving Yuma/Bear alone again.
• Fisticuff-Provoking Comment: In his backstory, he beats another inmate of the orphanage within an inch of his life for insulting the memory of his Boss. Twice.
• Hates Rich People: The most vehement about it of the Mukami brothers, due to his greater involvement in the political and social factors that led them all to the orphanage. He reserves a special ire for Shu, whom he regards as the embodiment of Idle Rich stagnation.
• Hair-Trigger Temper: Yuma is similar to Subaru in that his first response to anything that bothers him is to fly off the handle. So much so that Reiji points out their similar temperament in Vandead Carnival.
• Hope Sprouts Eternal: He is growing a rose bush as a memorial to his fallen friends which has been slow to bloom. When Yuma loses hope that he can accomplish his dream of becoming Adam in order to fulfill the promises he made to them, he smashes the bush. Yui saves the roses; they take root and bloom a short while later, signifying that there is still hope and they can overcome impossible odds together.
• Meaningful Rename: Karlheinz gave him the name Yuma after turning him into a vampire.
• No Challenge Equals No Satisfaction: Yuma is put off by the idea that Yui is an Extreme Doormat content letting other people control her life, and reacts harshly to her meekness. Yui does eventually work through how counterintuitive that is to realize that he wants her to express herself and likes when she shows some backbone.
• Orgasmically Delicious: This comes up in Yuma's More,Blood route, often involving produce he grew himself. Like speculating about adding cream to a dessert of fresh strawberries and Yui's blood.
• Over-the-Shoulder Carry: Frequently picks Yui up and carries her around as if it's the most natural thing in the world. Unfortunately for her, he is liable to drop her if he's in a bad mood.
• Personality Blood Types: Type O, which reflects his self-confidence and strong will.
• Pet the Dog: In the Mukamis' backstory, when Yuma first met Azusa, he found Azusa being beaten by a group of kids, only to drive them off. He then gave Azusa food and refused to hit him in place of the other kids. See Azusa's entry for his reaction to it.
  • He also has a moment in his More,Blood route with Yui when he encourages her to not give up on her dreams.
• Real Men Hate Sugar: Inverted. He likes munching on sugar cubes, and is completely unashamed about it.
• Real Men Wear Pink: His hobby is vegetable gardening. Yui is surprised and a bit delighted that a guy as intimidating as Yuma enjoys such a homey hobby.
• Recruited from the Gutter: After losing his memory as a child, he was welcomed into a orphan street gang - but a surprisingly wholesome one led by an older boy with revolutionary ambitions. Yuma, or Bear as he was called at the time, became the boss's top lieutenant.
• The Reveal: He is revealed to be Shu's friend Edgar, who was thought to have died in the fire that destroyed his village. He woke up with injuries but had no memory of who he was.
• Survivor Guilt: Averted in most cases. The memory of his fallen friends is usually a source of strength for him, but in one of his More,Blood bad endings he is psychologically shattered by a gruesome Guilt-Induced Nightmare to the point that he abandons his identity as Yuma and lashes out at anyone who addresses him that way.
• Trademark Favorite Food: He loves sugar cubes. Emphasis on "love" - he describes his fondness for sugar in terms of a love affair where he and "sugar-chan" do naughty things together.
• Tsundere: His main mode is prickly - extremely prickly. He became what he is because of the toxic environment he grew up in.
• Used to Be a Sweet Kid: Pre-amnesia, he was very lively and cheery. After his village burned down with his parents still inside and his amnesia following the incident, he had to become even tougher if he wanted to survive out on the streets with the other members of his gang. He grew violent, rough, and dominating with time.
• When Trees Attack: Special mention to the Played for Laughs scenario in More,Blood where a ghost and/or demon-possessed pumpkin vine accosts Yui in Yuma's garden. Yuma apparently regards these spirits as minor pests, while Yui is, quite naturally, terrified. And don't worry, the story doesn't squander the erotic potential of having Vine Tentacles wrapped around our girl's limbs, even if full-on Naughty Tentacles is out of the question.
• You Remind Me of X: Once Yui is confident enough to express herself to Yuma, he tells her that his boss from the slums used to say the same things that she says about persistence and holding on to self-respect when facing oppression.

Azusa Mukami

Voiced by: Daisuke Kishio (Japanese), Greg Ayres (English)

The fourth son who is timid, but nonetheless obstinate. Because of that tenacity, most of the time things end up going the way he wishes. He's an extreme masochist who enjoys being wounded.

---

• Adaptation Dye-Job: Azusa has black hair with grey tips and grey eyes in the dramas and visual novels, and blue-green hair and purple eyes in the anime.
• Babies Ever After: In his More,Blood VN good ending, he and Yui have three children. All of them are named after Azusa’s former “friends” and wounds: Justin, Christina, and Melissa.
• The Baby of the Bunch: Azusa is the fourth and youngest son of the Mukami household. The others call him their "problem child."
• Blade Enthusiast: He has a large knife collection that he maintains with great care, and he gushes to Yui about them.
• Brutal Honesty: Despite the fact that Azusa is willing to lie under certain circumstances, he is also more than willing to call out Kanato for the way he treats Yui, even going so far as to to outright tell Kanato he's making Yui unhappy.
• Combat Sadomasochist: He is a peaceable person so the "combat" part is a stretch, although he does try to provoke people into striking him. He is primarily a masochist so he likes to have others cause him pain. Sometimes he hurts himself as well to maintain scars and injuries that tie him to his past. He quickly identifies Yui as a fellow pain-seeker, so he tries to inflict pain on her based on an assumption that she will enjoy it.
• Covered in Scars: Has visible scars on his face and arms. Yui also discovers copious scars and injuries on his back during the obligatory Shower of Awkward scene, but the visuals do not show them.
• Dark and Troubled Past: From an early age, Azusa thought of himself as alone and unneeded, and was Desperately Looking for a Purpose in Life. He found it in three kids named Justin, Melissa, and Christina who would beat him up just to let off steam. His role as the terminal link of The Chain of Harm gave meaning to his existence, and he grew to enjoy the pain they inflicted on him. Justin, Christina and Melissa were scapegoated as thieves and publicly hanged. Asuza was beside himself with loss, and formed the basis of his wound delusion as a way to keep his memories of them alive. When concerned strangers brought him to the Orphanage of Fear, he was relieved to find he could take up his role as a punching bag again and was content to stay there.
• Friendly Neighborhood Vampire: As the only love interest who isn't a jerkass, he doesn't engage in the sorts of insulting, belittling, or humiliating behaviors that the other boys do. However, he is a Cloudcuckoolander and a masochist, and easily gets carried away when he interacts with Yui. He will bite her even when she seems reluctant because he thinks she feels the same desire for pain as him.
• The Gadfly: Azusa will purposely tease and provoke his brothers to get them to lose their temper and hit him.
• Let's Get Dangerous!: Since Azusa is basically immune to intimidation, he keeps his cool in the face of Kanato's rage-fits and is able to get the better of him, even though Kanato is more powerful than he is.
• Loon with a Heart of Gold: The other Mukami brothers worry about Yui's ability to cope with Azusa. After all, he talks to the wounds on his arms as if they are his friends. However, he has a twisted yet visible sense of right and wrong, and he genuinely wants to make Yui happy from square one.
• Major Injury Underreaction: His reaction to experiencing pain is somewhere between relief and getting turned on, and most people who observe it find it unsettling. His biggest underreaction occurs after Yui's father shoots him in the More,Blood VN. He doesn't mention to her that he was shot with a silver bullet, which causes him to waste away and will eventually kill him if left untreated.
• Mellow Fellow: He avoids conflict, and has the lowest energy of the entire cast. He speaks in a slow, halting manner that makes him seem a bit soft in the head, but he can be pretty devious when he wants to be.
• Nice Guy: Even though he has some masochist/sadist tendencies, Azusa stands out because he doesn't out go out of his way to be mean. He's never condescending towards anyone and is polite to Yui.
• Orphanage of Fear: He ended up in the same one as Ruki, Kou, and Yuma. The other kids in the orphanage beat him up but then he met Yuma, who was the first person who was kind and nice to him and gave Azusa hope for the future. See Ruki's entry for details on their escape.
• Personality Blood Types: He exhibits the type A stubbornness and desire to get along with others.
• Rich Suitor, Poor Suitor: In Azusa's storylines, he's portrayed as the Poor Suitor to Kanato's Rich Suitor.
• Self-Harm: It is key to his mental condition that pain is inflicted on him by other people, but his desire for pain is driven by similar motivations as self harm. Azusa feels like he barely exists and feeling pain at least means he is really there; and he seems to have a poor grasp of the concept of emotional pain, so he channels it through physical pain.
• Street Urchin: He started out as one when he was a child.
• Token Good Teammate: Of the Mukamis; he's the only one who of them who treats Yui nicely.
• Trademark Favorite Food: Shichimi togarashi, a hot and bitter spice blend perfect for making a meal painful.
• Weaksauce Weakness: He is incredibly weak against heat.

Tsukinami Brothers

Carla Tsukinami

Voiced by: Toshiyuki Morikawa (Japanese), Josh Morrison (English)

The King of the First Bloods and possessor of vast magical powers, he was imprisoned with his dying race after losing an ancient war against Karlheinz. He seeks vengeance against Karlheinz and the restoration of his people.

---

• Animorphism: As a Founder/First Blood, he can transform into a wolf, snake, bat and an eagle, but he is never shown doing so.
• Brilliant, but Lazy: Is stated to possesses both intelligence and reason yet because of his long lifespan, he seldom rushes into anything.
• Clothing-Concealed Injury: Carla's default outfit covers him almost head-to-toe, including Conspicuous Gloves and a trailing scarf that often covers his mouth. While it is legitimately a Scarf of Asskicking, It is also a hint that he's hiding the bruises that are a symptom of his fatal disease.
• Cruelty by Feet: Frequently steps on Yui as a humiliating punishment in the early parts of his Dark Fate route when she is defiant or tries to run away. And she tries to run away a lot.
• Does Not Like Spam: He dislikes Japanese food.
• Evil Cannot Comprehend Good: Carla disdains compassion as a signifier of weakness, so when Yui's love martyrdom comes online for him, he can't make sense of her actions. Even though his powerset includes Psychometry and he frequently tells her that he can read her intentions as plain as day.
• The Fettered: He takes his duties incredibly seriously and lives not according to what he wants, but what is expected of him. The prospect of hurting people in the process of fulfilling his duty does not deter him.
• Foreign Exchange Student: He and Shin pose as the children of expats returning from the UK in order to infiltrate Ryoutei Academy, so his Anglophone given name and Japanese surname are all part of his exotic appeal. The Japanese school system also offers special accommodations to help students like them adjust, which is why he and Shin have a classroom all to themselves.
• Gender-Blender Name: Carla is typically a girl's name.
• I Love You Because I Can't Control You: In his Dark Fate route, Carla becomes so impressed with Yui's courage and will to defy him that he falls for her without realizing it.
• Jerk with a Heart of Gold: Underneath his cruel personality, Carla has a soft side that he rarely shows.
• Karmic Nod: He thinks of it as his father's retribution against him when he starts showing symptoms of Endzeit. It's implied that he accidentally infected himself in the process of passing the disease from his mother to his father. While he is certain that he deserves it, he regrets what it means for the survival of the Founders.
• The Kingslayer: He defeated his father in a duel, but did not kill him. Rather, his father died of a fast-progessing case of Endzeit shortly thereafter. Because Carla intentionally infected him with Endzeit during the duel. It was an effective gambit because the only person who understood the infection process was Krone - who devised the plan on her deathbed and gave Carla her own infected blood to enact it.
• Long-Haired Pretty Boy: Has the longest hair among the love interests.
• Mama's Boy: He had a close relationship with his mother Krone, who would patch him up after his father's Training from Hell.
• Personality Blood Types: Type AB.
• Superior Successor: His powers are greater than those of his father, and he was on track to become the strongest of the Founders. Unfortunately, his talent only caused his father to resent him, and by the time he appears in the story he is losing strength.
• Supernatural Gold Eyes: He has gold eyes with vertical pupils.
• Tough Leader Façade: Over the course of the indeterminately long years the Founders spend imprisoned in their castle, Carla hardened into a merciless, unassailable, perfect king.
• Trademark Favorite Food: Ham; specifically the fancy dry-cured types like prosciutto. He engages in a surprisingly funny bit of villainous hospitality in Subaru's Dark Fate route, where he insists that Subaru samples some.
• "Well Done, Son" Guy: He worked hard to earn his father's praise when he was young, but nothing he did was ever good enough. Carla endured his father's Training from Hell without complaint, trusting that it necessary to prepare him for the throne. To his shame, he did not intervene when Giesbach imprisoned his mother due to a lingering desire to win his approval.
• White Hair, Black Heart: Carla has white hair and is a sadist, but not to the point of losing control.
• Wicked Cultured: He plays the antagonistic role in most of the other character's routes in Dark Fate. Carla expects to be obeyed, and does not take "no" for an answer when he orders anyone to do his bidding. However, he is not entirely harsh - he enjoys reading poetry and history books, and collects paintings when he is not in his duty as the King.
• The Wise Prince: Before tragedy struck the Founders he was noble, upright, and unusually for a Founder, willing to set aside his pride for the greater good.

Shin Tsukinami

Voiced by: Showtaro Morikubo (Japanese), Houston Hayes (English)

The younger brother of the First Bloods, with a personality much the opposite of Carla's - he is aggressive and talkative, yet conceals his own objectives. He is also very prideful, and as a result, quick to take offense.

---

• Animorphism: As a Founder, he can transform into a wolf, snake, bat and an eagle. However, he prefers his wolf form.
• Bait the Dog: If Shin does something kind or solicitous, he has ulterior motives. Often it's to set up a prank - probably a malicious and dangerous one. As he softens up around Yui the pranks become less violent, even cute, but he still loves to get the drop on her.
• Big Brother Worship: Zigzagged; he has a fraught relationship with his brother. While he puts Carla on an almost godlike pedastal, he also resents having to live in his shadow. He devoted his life to becoming more powerful than anyone else, and waits for the moment to put Carla in the position he has occupied his whole life.
• Conspicuous Gloves: Wears black ones with his school uniform.
• Crushing Handshake: In a nod the western foreigner cover story the Tsukinami brothers use, he requests a handshake when he introduces himself to Yui. He puts a bit too much strength into it, and draws attention to how physically strong he is with a disingenuous apology.
• The Dragon: He plays this role for Carla, but is on the verge of flipping to The Starscream.
• Eyepatch of Power: Wears an eyepatch and is considerably bloodthirsty.
• Eye Scream: The loss of his eye was a very painful formative moment for him.
• Fantastic Racism: In his reckoning, the Founders are a Superior Species, so everyone but Carla is his inferior. He particularly hates vampires, complaining about how bad they smell at every opportunty. He also takes any lack of deference from other characters, no matter how minor, as a slight against his honor - which is a problem because no one in the story kowtows to the Tsukinami brothers. Well, no one but Mertz.
• Fatal Flaw: Shin often underestimates his opponents and looks down on them, which sometimes gets him into serious trouble. For example, in Kanato's Dark Fate route, this gets Shin killed by Kanato, no matter the huge level difference in their powers.
• Faux Affably Evil: Shin is much chattier than Carla, and Yui starts his Dark Fate route assuming that since he is easier to engage, he will be easier to get along with. That doesn't work out very well. While Carla has goals in mind when he is cruel, Shin is cruel just because it amuses him.
• Four Eyes, Zero Soul: Two eyes in his case, since he only has one eye, and his teal-framed glasses only have one lens. Technicalities aside, he is a very sadistic character.
• Ineffectual Death Threats: In Shin's Dark Fate route, he and Carla have a falling out which would have been fatal for him if Yui had not put herself in harm's way. He is sufficiently frustrated by Yui's sympathy-driven motivations that he announces he will kill her...but only after holding her in his arms for a while. And of course, he never gets around to that first part.
• Personality Blood Types: Type O.
• The Social Darwinist: His worldview is based around Might Makes Right. Whoever is strongest is king, and Carla is the strongest. Shin worked hard to make sure that he is stronger than everyone else. Traumatic experiences in his younger years encouraged him to think that being stronger grants him a prerogative to humiliate the weak.
• Supernatural Gold Eyes: He has a sharp gold eye with a slit down the middle like his brother's.
• Trademark Favorite Food: He loves nuts.
• Tsundere: Type A. He looks down upon everyone aside from his brother.
• "Well Done, Son" Guy: A brother variant. Shin really admires his older brother and wants to prove himself to him.

Solo Characters

Kino

Voiced by: Tomoaki Maeno (Japanese)

The Vampire King Karlheinz's illegitimate son. For some unknown reason, he wants to destroy the vampire race.

---

• Animal Motifs: He is associated with crows for both cunning and creepiness, and they frequently appear around him, since the sole power that his Ghoul allies have is the ability to assume the form of a corvid.
• Aside Comment: Has a habit of saying snide things under his breath, and if anyone calls attention to this he will deny or distract from it.
• Backstory Invader: In Chaos Lineage he is integrated into the Elseworld as the youngest Scarlet brother, but as characters regain their memories they realize that he is actually a stranger to them.
• Bastard Bastard: He's an illegitimate child of Karlheinz and is shown to be just as sadistic and cruel as the rest of his family.
• Childhood Friends: With Yuri, the ghoul he grew up with.
• Dark Messiah: When he came into his powers as part of his Lost Eden backstory, his adoptive family held him up as a savior that would free the Ghouls from their Fantastic Ghetto. While he does identify with their plight and make efforts to maintain his messiah status, he mostly uses it as an excuse to throw his weight around.
• Personality Blood Types: Type AB.
• Phoneaholic Teenager: His favorite hobby is playing games on his smartphone.
• Psychopathic Manchild: He is a naive, selfish prince who thinks that it’s natural that people do things for him.
• Scarpia Ultimatum: Kino's Lost Eden route has a variation on this trope. Yui is at Kino's mercy throughout his route, so he can (and generally does) take any favor from her that he wants. However, he develops a Villainous Crush and offers Yui a deal: if she genuinely falls in love with him, he will spare Ayato (who, like Yui, is Kino's prisoner.) He is decent enough to give her time to consider, and holds up his end of the bargain in the meantime, but the whole deal amounts nothing when Kino's risky alliances fall apart around him.
• Tomato in the Mirror: He doesn't realize it, but his own account of his background is false. He is not even a vampire. He is some sort of spontaneously generated simulacrum based on Karlheinz.
• Trademark Favorite Food: It is also depicted in the Lost Eden trailer that Kino has a liking for guava juice. He chastises the heroine for "spilling his precious Guava Juice".
• The Trickster: His behavior is often whimsical and very difficult to predict, and coupled with his Karlheinz-level magical abilities he can cause some real chaos.
• Would Hurt a Child: In his Lost Eden route, he killed a ghoul child for trying to help Yui escape.

Other Characters

Karlheinz

Voiced by: Masataka Sawada (Japanese - Haunted Dark Bridal & More,Blood), Ryota Takeuchi (Japanese - Vandead Carnival onward), John Swasey (English)

The father of the Sakamaki brothers. He is the current Vampire King and head of the Sakamaki family.

---

• The Chessmaster: He orchestrates nearly all of the plot of the series and he foresees everything that occurs. He built his whole household around the Apple of Eden project, and keeps his family in the dark about the roles he intends them to play in his grand design.
• Death Seeker: He looks forward to the day when one of his sons grows strong enough to kill him.
• Disappeared Dad: He has neglected his sons since they were children.
• A God I Am Not: Many characters compare him to a god, but he himself plays coy about it.
• Inexplicably Awesome: He is ancient, uncontestably powerful, his abilities verge on reality-warping, and everyone in the cast seems to accept his existence the way they would a force of nature. Why is he the way he is? No one knows or thinks to ask; he simply is.
• Intrigued by Humanity: The reason behind his alter-ego as the politician Togo Sakamaki and his decision to drag his sons to the human world to pose as high school students.
• Lack of Empathy: When he shows up he often seems like the ideal Reasonable Authority Figure, and in many respects he is. Just not to his family, since he is incapable of love. He actually feels this lack acutely, and his understanding that all demons share an inability to love is what motivates his plans. Ironically, in his pursuit of a new race with demonic powers that is fully capable of human emotion, he subjects his family to intentional emotional neglect. It's no wonder everyone who associates with him is a basket case.
• Manipulative Bastard: He probably would need to rewind time less often if this was his forte, but he is certainly capable of it. After all, he planned Cordelia's entire existence starting from setting up her parents, and wooed her away from his own brother so she would have his children.
• Offing the Offspring: In some endings, Karl will kill his own sons if he feels like they failed him.
• Smart People Play Chess: He plays chess. With Socrates. And he always wins.
• Vampire Monarch: He has been the Vampire King for over 2000 years.
• Voluntary Shapeshifting: He has the ability to assume any appearance he wants. No one knows what he really looks like. Not even his sons.

Cordelia

Voiced by: Akane Tomonaga (Japanese), Monica Rial (English), Dolores Mondragón (Mexican Spanish)

Karlheinz's first wife. She is the mother of the triplets: Laito, Kanato, and Ayato.

---

• Abusive Parents: To all her children, in varying degrees. From initiating Parental Incest with Laito to ignoring Kanato unless he was singing and being incredibly hard on Ayato, it's safe to say Cordelia is far from being Mother of the Year.
• Alpha Bitch: She used her status as the first wife as well as the Demon Lord's daughter to torment Beatrix by degrading her and trying to prove that her children were better than Beatrix's.
• Asshole Victim: Very few people mourn her passing. Probably only one.
• Ax-Crazy: Despite appearing and behaving well-mannered, she can make up for madness.
• Back from the Dead: She would be a Posthumous Character if not for her transplanted heart, which makes it possible for her to cheat death. She takes over Yui's body in the anime and some paths of the first VN, and she pops up again in a magical construct body in Ayato's Dark Fate route.
• Bastard Bastard: A reprehensible person; plus in Dark Fate, it's revealed that Cordelia is the illegitimate daughter of Demon Lord Burai and a mistress.
• Because You Were Nice to Me: Believe it or not, Cordelia is capable of kindness. Yui nurses her back to health in Ayato's Dark Fate route, and she gets one hot second of playing Cool Big Sis. All her advice to Yui is terrible, but it comes from a place of genuine fondness.
• Education Mama: She was extremely strict with Ayato, forcing him to study constantly and scolding him for wanting to play with his brothers, even going so far as to throw him in water, despite knowing that he couldn't swim at the time.
• A Family Affair: She had Richter wrapped around her finger even before she married Karlheinz, and when Karl started ignoring her, she lured Richter back to her side. She'd drop Richter in a heartbeat if it meant she could have Karl's attention again.
• Females Are More Innocent: Cordelia has her own Freudian Excuse, starting with a loveless childhood where her mother died young and her father was neglectful. Karlheinz swept her off her feet and made her feel loved for the first time in her life. However, Karl actually was after her blood for his project and only pretended to love her so she would give him children, and eventually he lost all interest in her. It makes her a more pitiable character, though it in no way excuses the abuse she inflicted on her own children.
• Femme Fatale: She uses sex to manipulate for selfish ends. Her seduction methods are genteel even if she is utterly shameless about where she deploys them (lady, your kids are in the room,) and she is only interested in her partners while she has something to gain from them.
• High-Class Gloves: In a continuation of the Fashionable Asymmetry design trend, she wears a black opera glove on her left hand. Her Hot Consort chic is not to be denied.
• Hybrid Monster: Her sobriquet "Daughter of the Demon Lord" indicates that she is half-vampire, half-demon. But in Dark Fate she is revealed to actually be half-demon (specifically Vibora, the snake clan) half-First Blood. Even she was not aware of this, as she knew nothing about about her mother.
• Inferiority Superiority Complex: Just like her paramour Richter, Cordelia has a bad case of this. She's quick to sneer at the other wives for thinking Karlheinz actually loves them, yet she abused and pushed Ayato too hard, depriving him of his childhood just so she could impress her husband. She even started an argument with Christa that turned into a fight when Christa scoffed that Karlheinz was just using Cordelia, showing how badly she craved his affection and approval.
• Lecherous Step Parent: Towards Reiji while inhabiting Yui's body. In the VN, the route where Cordelia fully possesses Yui is Reiji's, and she takes advantage of his attraction to Yui to try to win him over. He plays along, but is fully aware of her intentions. The anime mirrors this when she compares him to Karlheinz and kisses him.
• Mandatory Motherhood: She did not want to have children, but did so because of Karlheinz.
• Manipulative Bitch: She was able to convince Richter that she would make him the Vampire King if he resurrected her.
• Mother Makes You King: Cordelia only wanted Ayato to be king to have Karl's love and affections. Although, she does get her wish in Lost Eden in all three of her sons' routes.
• Parental Incest: With Laito, only to cast him aside for his uncle, Richter, when Karlheinz found out about her relationship with Laito.
• Proud Beauty: She knows all too well that she is attractive and becomes resentful and frustrated toward men who resist her charms.
• Strong Family Resemblance: Kanato has her hair, while Laito and Ayato have her eye color.

Beatrix

Voiced by: Mana Hirata (Japanese), Luci Christian (English), Rosalinda Márquez (Mexican Spanish)

Karlheinz's second wife. She is the mother of Shu and Reiji.

---

• Out of Focus: As the visual novels progress, Beatrix gets less attention than Cordelia and Christa, whose backstories continue to develop. Beatrix is the only one among Karlheinz's wives whose background hasn't been fleshed out.
• Parental Favoritism: She focused more on Shu than Reiji because Shu was the oldest and therefore heir to the family.
• Parental Neglect: She loved Reiji deeply, but never gave him the attention he needed.
• Parents as People: Beatrix was a rather decent mother, especially when compared with Cordelia or Christa. Unfortunately for her, Karlheinz only married her to be a rival to Cordelia, so that when Beatrix dutifully produced heirs, Cordelia would feel obliged to follow suit. And Cordelia took the rivalry very seriously - far more seriously than Beatrix ever did. Beatrix grew so weary of Cordelia's bullying that she thanked Reiji for arranging her death.
• Shared Family Quirks: Both Beatrix and Shu are closed off from other people while being warmer than they show at first glance. In Beatrix's case, it's primarily due to the burden of responsibility that came with raising Shu to be his father's heir, as well as having to deal with Cordelia.
• Strong Family Resemblance: Shu gets both his hair and eye color from Beatrix.

Christa

Voiced by: Yuki Tashiro (Japanese), Brittney Karbowski (English), Martha Ramírez (Mexican Spanish)

Karlheinz's third wife later revealed to be his cousin as well. She is Subaru's mother.

---

• Ambiguous Situation: In her first appearances Christa begs Subaru to kill someone, but it is unclear if she means her husband or herself. (Japanese syntax allows for this without seeming too awkward.)
• Delirious Misidentification: In most of Christa's appearances she is affected by madness and mistakes those around her for people from her past.
  • She conflates Subaru with Karlheinz, but not always the same version of him. Most of the time she thinks he is Karlheinz-as-her-husband and shrinks from him in fear, but occasionally he becomes Karlheinz-as-her-brother and she looks at him adoringly. Subaru is horrified by this either way.
  • When she meets Yui in this state, she mistakes her for Cordelia. Yui's compassion leads her to play along with Christa's delusion, but eventually it goes sour when Christa tries to murder her.
• Dying as Yourself: In Subaru's Dark Fate route she is fatally poisoned, but she is lucid on her deathbed and explains her relationship with Karlheinz to Subaru - specifically, how it went awry. She was curious about his research, and went mad from the revelation that she was nothing more to him than a subject of that research.
• Flower Motifs: White roses symbolize her innocence and purity, as well being wilted after being using by her husband.
• Good Parents: Surprisingly, yes. In Christa's saner moments, she's a doting, gentle mother towards Subaru and a vocal Shipper on Deck in Subaru's More,Blood route.
• Kissing Cousins: With Karlheinz; he wanted her to marry him specifically because they were closely related, although he never revealed that to her. The fact that Christa thought of him as her brother until that point does nothing to improve the situation.
• Insane Equals Violent: She has drastic mood swings when she is delirious, sometimes destroying things around her and hurting people.
• Rape as Backstory: Implied in the first plotline, where all of Christa's appearances involve her reacting to her husband's presence (whether real or imagined) with utter terror. Becomes a subversion when it's revealed that her feelings for Karlheinz are more complicated than that: she does love him and willingly married him. Her mind was broken when she learned Karlheinz had pretended to love her.
• Shared Family Quirks: She has a habit of destroying things around her and lashing out at people when she's angry, just like her son. Both of them can also be very gentle and sweet when they're not angry.
• That Thing Is Not My Child!: Due to her mental instability she sometimes acts as if Subaru disgusts her; blaming him for her unhappiness and implying that he is fundamentally foul or unclean.
• The Tragic Rose: She was known as the White Rose and famed for her beauty. Unfortunately, her marriage to her husband and being used to bear his child solely for his experiments caused her to wilt away.

Richter

Voiced by: Jun Konno (Japanese), David Matranga (English), Ismael Verastegui (Mexican Spanish)

Karlheinz's younger brother making him the Sakamaki brother's uncle.

---

• Death by Adaptation: Richter dies in several routes of the first VN, often off-screen, but the rising tide of time-rewinding lifts all ships and he doesn't irrevocably die until Kino kills him in Lost Eden, the fourth VN. The anime gives him a Disney Death at the end of the first story arc, but since he never makes another appearance, it's as good as final.
• Evil Uncle: A pretty classic example - he is the younger brother of a king, has always played second fiddle to his elder brother, and has legitimately suffered due to the outsized influence his brother has on his life. The only viable means of usurping Karlheinz available to him is cheating his nephews.
• Inferiority Superiority Complex: Richter's got this bad. He has spent most of his life feeling trapped in his brother, Karlheinz's shadow. On the other hand, he's incredibly conceited toward his nephews and is all too happy to look down on them.
• Love Triangle: He's actually in two: Him, Cordelia and his brother Karlheinz, then another one with him, Cordelia and his nephew and Cordelia's son, Laito.
• Manipulative Bastard: In the anime, he managed to trick Cordelia (who is a fairly good manipulator) into thinking he actually loved her in order to become stronger than his brother and become the head of the family.
• Red Eyes, Take Warning: His eyes are red and no good ever comes of his presence.
• Reforged into a Minion: He dies in the prologue of Lost Eden, but even that is not Richter's final humiliation. The Church developed a method of reanimating vampires as loyal servants and they test it out on his remains.
• The Rival: He is this to Laito for Cordelia.
• Sibling Rivalry: He is Karlheinz's younger brother and is determined to surpass him.
• Sycophantic Servant: He's this to Cordelia, being more than happy to shower her with affection and compliments. At one point, he even goes so far as to call Cordelia a good mother. This is despite her sleeping with him in front of her children at various points, to start.

Seiji Komori

Yui's adoptive father. He is a priest.

---

• The Faceless: In the first episode of the anime, Yui finds a picture of her and her father when she was still a baby but we only see him from the mouth down.
• Knight Templar Parent: Love interests occasionally challenge Yui about whether or not her father really loved her, since he never came back for her. It turns out that he did. Past-tense, because as far as he is concerned his daughter is dead - sold-out by people she trusted and devoured by monsters - and the lives of everyone who hurt her are forfeit.
• Offing the Offspring: Seiji makes appearances in two More,Blood routes - Azusa's and Kanato's - and the encounters are similar. Looking for respite, Yui returns to the church where she lived and finds her father has come home. It's heartwarming until he senses something off with her. He says that she has become a vampire and is no longer the daughter he loved, and attacks her. In either case, Azusa takes the bullet for her, and in Kanato's route he dies from his injuries.
• Vampire Hunter: Revealed to be one in Reiji's Route. Reiji hired him to kill his mother Beatrix.
• The Voice: In the games, he has no sprite but we hear his voice when he talks to Yui in flashbacks.

Giesbach

The First Blood King and the father of Carla and Shin.

---

• Abusive Parents: He hated Carla, his own heir, for being destined to surpass him and subjected him to needlessly cruel training which escalates into a low-key Uriah Gambit. However, he doted on Shin to the point of stifling him.
• Domestic Abuse: He was so affronted by Krone's request to abandon his rivalry with Karlheinz and focus instead on the survival of his own subjects, that he ordered Carla to imprison her in the castle dungeon.
• Hate Sink: Being such an egotist to the point of starting a war that resulted in the near-extinction of his people out of a petty rivalry with Karlheinz, abusing his son because he could not accept his greater potential while having the nerve of saying him joining the war would compensate "all he did" to him, ordering his wife to be imprisoned only for saying he should stop his jealousy from causing the end of the Founders, using the war to kill Carla and Karlheinz indirectly while not joining the battlefield himself, Giesbach is established as one of the most loathsome flashback characters.
• Honor Before Reason: Giesbach surrounded himself with advisors who fed his ego and encouraged his belief that the Founders were invincible. He led his race into defeat at the hands of Karlheinz and near-extinction by underestimating the threat of the Endzeit plague.
• It's All About Me: All of Giesbach's actions that led to the near-extinction of his race were motivated by a fragile ego unable to accept Carla or Karlheinz surpassing him.
• The Voice: All of the Founder flashback characters, including him, do not have a sprite or even concept art.

Krone

The First Blood Queen and the mother of Carla and Shin and older sister of Menae.

---

• Cool Big Sis: Her younger sister, Menae, deeply respects her greatly and would listen to her requests without any questions. In fact, when Krone was the one who told to go to Karlheinz to find a cure for their dying race with Menae following her sister's wishes despite not understanding the reasons.
• The High Queen: She cared about her people greatly and was willing to tell her husband to stop his petty rivalry with Karl to focus on finding a cure for their people instead. Unfortunately for her, Geisbach didn't care what might happen to their race and hit her in front of their eldest son, Carla, for dealing to speaking to him that way.
• Shoot the Dog: She considered it her duty to kill Giesbach before his madness completely destroyed the Founders, but she very nearly acted too late.

Menae

The younger sister of Krone and the aunt of Carla and Shin. It's later reveal in Dark Fate, she's also the mistress of Burai and and the mother of Cordelia, making her the grandmother of Laito, Kanato, and Ayato.

---

• Posthumous Character: She is long dead as evidenced by Cordelia's Freudian Excuse loveless childhood. Her death means there are no pureblood Founder women left alive.

---
