Characters
Protagonist:
The main character of the game and anime (name is changeable in the games)
Yui is the main female protagonist of the Diabolik Lovers series. She is a beautiful, kind, gentle, and clumsy 17-year-old student, who used to live with her father, a priest, who owns his own church. After her father moved overseas for work, she was forced to live in a mansion with six mysterious brothers, who are actually vampires. In the beginning, she was skeptical of their supernatural nature but came to find no other solution. In a struggle for survival, she decides to live with them, while bearing the fear of being attacked by each of them. She is the sacrificial bride legend of the Sakamaki vampires and the chosen "Eve" for Karlheinz's "Adam & Eve" plan. Despite being mistreated by the vampires, Yui always responds to them with kindness and attempts to understand them better. In the first episode of the anime's first season, it is revealed that she is adopted, and hence, begins to investigate her past. She also starts suffering chest pains while living with the Sakamakis, due to the fact that her heart was originally Cordelia's, who was the mother of the triplets named Ayato, Kanato, and Laito. This explains why all of the brothers were highly drawn to her blood.
Sakamaki Household
The Sakamaki brothers are the sons of Karlheinz, but from three different mothers. The oldest sons, Shū and Reiji, were conceived by Karlheinz's second wife, Beatrix. The triplets, named Ayato, Kanato, and Laito, were born from Karlheinz's first wife, Cordelia. The youngest, Subaru, came from Karlheinz's third wife, Christa. Even though they are brothers, they don't get along with each other, and they seem rather distant due to the way they were brought up.
Sakamaki Shu (逆巻 シュ)
(Child)
Shu is the eldest son of the Sakamaki family, the current master of the mansion, and the first son of Beatrix. Shū grew up being given too much-unwanted attention from his mother. Due to Cordelia's hostilities towards Beatrix to be Karlheinz's best wife, she put all the pressures on the young Shu. He is one of the brothers who seem to have any prior knowledge of Yui's arrival, mentioning "that person" had contacted him asking to have her stay with them as a guest. According to the students of the school, Shū is the owner of the music room and can always be found sleeping there. Shu needs to use a lot of persuasion in order to get him awake and do something for himself. Shū loves music despite being apathetic and lazy. His only friend was a human boy named Edgar, who died in a fire, set on his village by Reiji. Shu was unable to save him, so he thought that his life was limited from humans. Despite Shū being the eldest, he's never responsible for looking after his brothers and the house. Instead, he mostly pushes these duties onto Reiji.
Sakamaki Reiji (逆巻 レイジ)
(Child)
Reiji is the second son of the Sakamaki family and the second son of Beatrix. He is very formal and is generally the most composed aside from Shū. Although Shū is his only full-blood brother, he despises him for being the supposed favorite of their mother. It was also due to Beatrix neglecting him throughout his childhood because of Cordelia's hostilities. He eventually took his anger out by setting fire to Edgar's village when Shu refused to listen to their mother. When it seemed that Edgar's death wasn't enough to impress his mother and made Shū withdrawn, Reiji took out his anger again by hiring a vampire hunter to assassinate Beatrix. He later regretted this when she died at peace, happy to be freed from Cordelia's harassment and to be able to witness her son's mark of adulthood. He values rules and demands that others follow them, even though many of his decrees are odd and self-made. Reiji chooses to be the role model of the house even though he is the second son. Although Reiji has a very polite attitude and almost always acts like a gentleman, he is a man of very harsh words. Along with his passion for experimenting and making drugged potions, he loves to collect kitchenware.
Sakamaki Ayato (逆巻 アヤト)
(Child)
Ayato is the third son of the Sakamaki family, the eldest triplet, and the first son of Cordelia. He is the lead male protagonist serving as the storyline's hero. As a child, Ayato was similarly put pressure upon to be the best, just as Shū was. However, unlike Shu, he never received love from his mother. He was abused by her (both physically and verbally) to the point where she attempted to drown him if he was not the best. Therefore, he grew up always having to be the best; causing him to develop a self-centered, arrogant, and overconfident personality. He refers to himself most of the time as "Ore-sama". Due to never receiving any type of love from his mother. He is the first of the Sakamakis to appear at the beginning of the first episode of the anime's first season, as well as the first one to drink Yui's blood. He is also very good at playing basketball, and his favorite food is takoyaki. Prior to the start of the series, Ayato and his triplet brothers killed their mother. He stabbed Cordelia and drank her blood, claiming it to be the best.
Sakamaki Kanato (逆巻 カナト)
(Child)
Kanato is the fourth son of the Sakamaki family, the second oldest of the triplets, and the second son of Cordelia. He is usually referred to as the "problem triplet". As a child, he received little attention from his mother. Very often, Cordelia would have sexual encounters with different men right in front of him. Due to being neglected, he often played alone and talked to his dolls, usually to his precious Teddy which he takes with him everywhere. However, there were occasions when his mother would request him to sing for her. She nicknamed him her "little songbird", because of his beautiful voice. Kanato tends to cry often and gets violently angry when he doesn't get his demands. He speaks politely, but is extremely sadistic and tends to display violent outbursts. He is also shown to be abusive. Kanato is also obsessed with the dead to the point where he prefers them to the living. Prior to the start of the series, he and his triplet brothers killed their mother. Kanato burned her body and placed her cremated remains in his Teddy.
Sakamaki Raito (逆巻 ライト)
(Child)
Laito is the fifth son of the Sakamaki family, the youngest triplet, and the third son of Cordelia. He was sexually abused by his mother and began seeing her as a lover rather than a parent. When Karlheinz found out about the unusual relationship between them, he locked him in the basement. Later, Cordelia went to see him and told him that she was now having sexual relations with someone else and had only been using Laito for pleasure. The overall shock and the situation ended up with Laito becoming perverted and not having a clear understanding of love. He is always cheerful and loves to joke but is similar to Ayato when teasing Yui. However, his personality suddenly changes when something goes against his wishes, usually when Yui is too defiant around him. However, Laito has a phobia of insects, specifically spiders. Prior to the start of the series, Laito and his triplet brothers killed their mother. He pushed Cordelia off the balcony after pretending to help her fend off Ayato who had stabbed her and drank her blood earlier on. In terms of manipulation and scheming, he is arguably the worst of all the brothers. Intelligent, quick thinking, and skillful in his lies, he is the only brother that actively attempts to drive the MC insane. Highly dangerous, avoid.
Sakamaki Subaru (逆巻 スバル)
Subaru is the sixth and youngest son of the Sakamaki family and the only son of Christa. He is usually alone and never cares about whats happening around him, due to how he was brought up. His mother became mentally unstable after he was born, which made his relationship with her very complicated. Christa kept denouncing him as her son (both physically and verbally), and was constantly pressuring him to kill her, which was something he could not bring himself to do. This caused Subaru to see himself as filthy and unwanted, thus resorting to violence to vent out his anger and frustrations. He even goes as far as to break everything when he is extremely angered. However, Subaru manages to compress this side when he is around Yui, though he is still prone to outbursts. He is a delinquent type who loves to damage things, but there is a tsundere and gentle side of him that only Yui can see. He happens to care about Yui when he encouraged her to escape the mansion while she still had the chance. When Yui chose to stay in order to find the answers to her questions, he reluctantly complied with her decision by giving her his silver knife to protect herself. It is also hinted that Subaru is in love with her, though he denies such a possibility.
Kino (キノ)
Kino is said to be an illegitimate child of Karlheinz. He made his first appearance in the sixth franchise of the series, Diabolik Lovers, Lost Eden. He was abandoned as an infant in a land called "Rothenberg" and was raised by a family of ghouls. However, living among the ghouls was not easy for Kino as he was discriminated against, bullied, and shunned. Everything changed for him one day when his vampire powers were awakened, which made Kino convinced that he was the illegitimate son of Karlheinz. Using his powers, he made the ghouls obey him and he decided to kidnap Yui in order to become Adam with her as Eve.
Mukami household
The Mukami brothers were new characters who debuted in the second version of the franchise, Diabolik Lovers More, Blood. Unlike the Sakamaki brothers, they are not blood-related to one another. They were originally humans who were later turned into vampires by Karlheinz, who serves as their benefactor. The Mukami brothers made their first anime appearances in the OVA of Diabolik Lovers and they appeared as new characters in the second season of the anime.
Mukami Ruki (無神 ルキ)
Ruki is the eldest son of the Mukami family and is known as the 'Brains' of the group. When he was still a human, Ruki was the son of an aristocrat. As a child, he was spoiled and arrogant until his family went bankrupt. He became an orphan after his father committed suicide, while his mother ran away with her secret lover. This caused Ruki to distrust people since his mother never came back for him, even when she told him in a letter that she still loves him. Ruki ended up in the orphanage where he was bullied by the other orphans and mistreated by the staff since he was a former aristocrat until he met his brothers, Kou, Yuma, and Azusa. He devised a plan to escape the orphanage which failed when he and his brothers got shot by the orphanage staff, resulting in him getting branded as 'livestock' on the back as punishment. Just as he was dying, he met the Sakamakis' father, Karlheinz, who offered him another chance to live but as a vampire. Ruki immediately accepted the offer, seeing this as an opportunity to get revenge on those who abused him and deprived him of his humanity. As the leader of the Mukami's, Ruki is a cruel manipulator with a cool attitude who is able to keep things under his control and a bit of kuudere which Yui notices. He is often seen carrying a book around with him which is said to be a memento of his father. In the second season of the anime, he is the first of the four brothers to drink Yui's blood. He is also rivals with Ayato and seems to enjoy taunting and provoking him when it comes to Yui.

As a founder, he has the ability to transform into a wolf, snake, bat, and eagle.

Tsukinami Shin (月浪 シン)
Shin is the younger brother of Carla. He possesses a high pride due to being a founder, he looks down upon vampires of other bloodlines. Beautiful blood is his preference and often utters narcissistic remarks.

Richter had the heart implanted into Yui when she was still an infant, and he handed her over to Seiji Komori who raised her as his daughter since then. He later returns to the Sakamaki mansion and he starts watching Yui from the shadows in order to observe the 'awakening'. However, it is later revealed that Richter never loved Cordelia from the very beginning, and was only using her as a tool in order to become the next head of the Sakamaki family.

This backfires when Richter reveals that he never loved her from the very beginning.

His only desire that time was to see the vast blue sky out of his manhole. He ended up in the orphanage where he became a playtoy for the aristocrats due to his beauty. He was abused every day and he forced himself to accept being a playtoy since he was able to have a lot of nice things from the orphanage. This resulted in him losing his right eye, and since his wounds weren't given time to heal, he ended up having scars all over his body. As a result, Kou grew up believing that the world is about 'give-and-take'. He met his brothers, Ruki, Yuma, and Azusa, and attempted to escape the orphanage with them, but was shot by the orphanage staff. He met Karlheinz as he was dying and was offered another chance to live, but as vampires. Kou accepted the offer, seeing this as another chance to see the blue sky. After he was turned into a vampire, Karlheinz gave him a magical prosthetic eye that enables him to see into people's hearts. Due to his childhood trauma, Kou developed a two-faced personality that only surfaces when something doesn't go his way or when Yui is defiant. On top of that, he works as an idol in the present human world which gives him the advantage of using his beautiful and pristine features to deceive his fans and others. He is also rivals with Subaru and seems to enjoy provoking him when it comes to Yui.
Mukami Yuuma (無神 ユーマ) / Edogā (エドガー)
Yuma is the third son of the Mukami family and is the tallest out of his brothers. He is actually Edgar, Shū's only human childhood friend whom Shū thought had perished in a fire. Yuma, then Edgar had actually survived the fire due to unknown circumstances but had lost all his memories of his past and who he was, resulting in him suffering from amnesia. He later joined a street gang and went under the name 'Bear'. In order to survive on the streets, he had to abandon his timidness and innocent traits; becoming, rough, violent, aggressive, rebellious, and dominating over time. The rest of his gang got killed during a coup d'etat and by unfortunate luck, he was the only survivor. He ended up in the orphanage where he met his brothers, Ruki, Kou, and Azusa, and attempted to escape with them, but was shot by the orphanage staff. He met Karlheinz as he was dying and was offered another chance to live, but as vampire. He accepted the offer, seeing this as another chance to fulfill his gang boss's dream; to get rid of the aristocrats and have a world where there are no social classes. Karlheinz renamed him "Yuma" after he was turned into a vampire. Whenever Yuma gets angry, he normally goes on rampages. He is a delinquent type with a passion for vegetable gardening and a bit of a tsundere which Yui notices.

Mukami Azusa (無神 アズサ)
Azusa is the fourth and youngest son of the Mukami family. When he was still a human, Azusa was an orphan who had no knowledge of his birth parents. He also doubted his existence and believed that his life had no meaning until he was picked up by three thieving children named; Justin, Melissa, and Christina, who would constantly beat him up for any ridiculous reason. However, the more Azusa was beaten up, he began to enjoy it and started seeing pain as his meaning of existence, believing that being able to feel pain would confirm that you're alive. This continued until Justin, Melissa and Christina were killed when they attempted to rob an aristocrat. Azusa started constantly cutting himself after their deaths and named three prominent cuts on his arm to immortalize them. He soon ended up in the orphanage where he became a punching bag for the other orphans until he met his brothers, Ruki, Kou, and Yuma. When Ruki devised a plan to escape from the orphanage, Azusa was hesitant until Ruki punched him. He agreed to go along with the escape plan and was shot by the orphanage staff. Karlheinz appeared before him as he was dying and offered him another chance to live, but as vampires. Azusa accepted the offer in order to feel pain again and was considered a pitiful human before being turned into a vampire. He is the only one out of the Mukami's who seems to treat Yui decently. Alongside his passion for knife collecting, the way he speaks is quite timid and he is a bit of a yandere. He is also rivals with Kanato and seems to enjoy provoking him.
Beatorikusu (ベアトリクス)
Beatrix is Karlheinz's second wife and the mother of Shū and Reiji. Not much is said about her marriage to Karlheinz, but even though she was his second wife, she conceived before Cordelia making Shū and Reiji the oldest sons. Cordelia despised her because of that and constantly tormented her. This caused Beatrix to end up focusing all her attention on her first-born, Shū, in order to groom him into Karlheinz's heir, while unintentionally neglecting her second-born, Reiji. In reality, Beatrix truly loved both her sons and cared for them sincerely, but she found it difficult to express those feelings due to her serious and awkward personality. Prior to the start of the series, she was killed by a vampire hunter whom Reiji hired, but Beatrix died at peace; happy to be freed from Cordelia's harassments and her regrets of how she had raised her sons.
Kurisuta (クリスタ)

Subaru was convinced that it was his fault for being conceived and he was constantly pressured by his mother to kill her with a silver knife that can annihilate vampires.
Komori Seiji (小森 セイジ)
Seiji is Yui's priest father who runs his own church. Not much is said about him, but prior to the start of the series, he suddenly had to go overseas for work and he left his daughter in the care of the Sakamakis. In the anime, Yui finds out that he is not her real father after discovering his diary. He is later revealed to be a vampire hunter whom Reiji once hired to assassinate his mother, Beatrix.
A group of thieving children whom Azusa was previously with before he met his brothers, and before he became a vampire. They constantly bullied Azusa, and their abusiveness towards him was the cause of his masochistic mindset. Even though Azusa knew that they had treated him horribly, he still considered them his 'family' since they had saved him from dying on the streets. He was deeply saddened by their deaths after they were killed for attempting to rob an aristocrat. This also caused him to develop his self-harming habit, by slicing himself and naming three prominent wounds on his arm to immortalize his bullies.
Rukusu (ルクス)
He was the leader of a street gang Yuma joined before he met his brothers, and before he became a vampire. Yuma looked up to Lucks who scavenged, stole or worked hard in order to provide for himself and his gang.

Yuma was traumatized when Lucks and his gang were all killed during a coup d'état, leaving him as the sole survivor.
