Mikuni has short blonde hair with a bit of it fallen over his face. He usually wears a dark brown hat with a red band around it, and is shown to have two thin clip-on plaits on the right and one on the left side of his hair. He is a lean, tall man with brown eyes.
He is seen wearing a long-sleeved white shirt with a brown vest over it. He also wears beige pants paired with above-the ankle black boots and a mandarin colored scarf.
Mikuni is almost always seen with a small female doll which he names Abel, and it is easy to see that he really has a soft spot for this doll, often shooing away people who he claims is looking at her with 'lewd' eyes. His clip-on plaits might be worn because of his love for Abel, as the doll too, has plaits similar to the ones he dons.
At first glance, Mikuni is rather eccentric and strange, particularly his fondness for his female doll Abel and has a habit of misunderstanding people's skeptical gaze towards him as them staring at Abel "lustfully". His attachment towards his doll is so strong that he becomes frantic and rather childish in his behavior, which annoys the people around him, particularly his younger brother Misono and his Servamp Jeje.
Behind his childish behavior, Mikuni is actually a mature and calculating individual, and even cunning since he was a child. He is fully aware of how dangerous the current battle is, so he doesn't hesitate to kill his enemies or anyone that he thinks are too dangerous to be left alive, showing how cruel he can be if he thinks it's necessary.
Mikuni was the first child of Mikado Alicein and seemed to have a good life for a long time. He was educated by a house teacher (which is revealed to be Misono's mother) and Hattori. According to Hattori, Mikuni used to be a very talented chess player and even won against Hattori and his father.
After Mikuni's mother killed Misono's mother out of jealousy, she and his father took Misono into their house and Mikuni got a little brother. Mikuni started to hate his father for betraying his mother, something that Mikuni directly told his father, but he also truly loved Misono.
One night, seven years ago, his mother finally succumbed to her jealousy due to Doubt Doubt's uncontrollable power overflowing inside her, leading her to try to kill Misono. Mikuni, not wanting his beloved brother to be killed, resorted to killing his mother instead in order to save his brother's life, something that Misono witnessed. Despite not fully understanding what happened, Misono assisted Mikuni and Doubt Doubt to escape from the mansion. After that incident, he made a contract with Doubt Doubt, renaming him Jeje, and never returned to the Alicein manor.
It's not known what he did in the meantime, but when he was on the streets, he was found by the young C3 member, Tsurugi Kamiya. Tsurugi took Mikuni in and Mikuni eventually became a member of C3. He shared his room with Tsurugi and was also in a C3 team with him. It is revealed in Chapter 45 that part of the reason why Mikuni hates Tsurugi is because Tsurugi has been killing humans, not just vampires. It has not been revealed how long he had been with C3 or why he left the organization, but Syuhei revealed that Mikuni has some sort of connection with upper brass of C3.
First Meeting with Mahiru and Kuro
Mikuni appears for the first time when Servamp of Sloth, Sleepy Ash, currently going by the name Kuro, is falling into rage during his fight against Sakuya and Berkia. He had his Servamp, Jeje, calm Kuro down by shooting him in the back several times, after promising his Servamp that he will allow him to drink his blood. Just before he had revealed himself, Mikuni had called Dodo and told him to come take Misono to a hospital because he was hurt in battle against Sakuya.
Mikuni only tells Mahiru his first name and does not say anything about being Misono's older brother. Mahiru doesn't know how to feel about Mikuni; he considers him strange because he was talking to his doll named Abel and accuses Mahiru of looking at his doll with lewd eyes when he notices his skeptical gaze. They are interrupted by Jeje who demands Mikuni to fulfil his promise to let him drink his blood, but Mikuni pretends not to hear him, which angered Jeje who begins to shoot him, which Mikuni easily dodges. Mikuni then explains to Mahiru that, if an Eve doesn't know what he wants or fears the Servamp's power, the Servamp falls into rage and devours his own Eve. He offers to teach Mahiru how to end his contract with Kuro if he feels like it. Just before he leaves, Mikuni tells Mahiru that he should have killed Sakuya to do him a favor.
Alliance with Mahiru and Kuro
The next time Mikuni meets Mahiru is when he and Doubt Doubt are fighting one of Tsubaki's Subclass. He then uses his Lead, "My Fair Lady", in which his doll, Abel, grows as heavy as the sins of his target. After the Subclass dies due to Jeje's bite, Mahiru tells Mikuni that killing the Subclass was unnecessary, but Mikuni disagrees and states that they are at war- and Tsubaki, alongside all his Subclasses, are their enemies. Mahiru does not complain any further and instead asks Mikuni to show him how to use his Lead. Mikuni thinks Mahiru is naive because he is too good-willed, but agrees to help him. He then reveals his full name and thanks Mahiru for befriending his brother, Misono, which greatly shocks Mahiru and Kuro.
The three of them continues their talk at a restaurant. Mahiru still can't believe that Mikuni is Misono's brother because the two are nothing alike. To prove his relations with Misono, Mikuni imitates Misono's behaviour when he is angry and begins complaining about the restaurant in a loud voice and uses improper language, earning him a smack. Mahiru is embarrassed by this behavior and apologizes to the restaurant staff in Mikuni's name. Mikuni then shows Mahiru and Kuro pictures of Misono as a child and explains that Servamps have served the Alicein household for many generations.
He states that he has two goals: first that he would like to work together with Mahiru because Kuro is the strongest Servamp. Second is that he wants to collect information about Tsubaki in order to defeat him and knows his true goal. When Mahiru mentions the vampire SNS has been closed down, Mikuni reveals he has contacted the ones managing the site, which turns out to be some sort of institution led by humans who work to stabilize the coexistence of humans and vampires (it is later revealed that he is talking about C3). After seeing Mahiru's willingness and determination to become stronger so he can stop Tsubaki, Mikuni agrees to train Mahiru together with Lily and Jeje.
Training Mahiru and Tetsu
When they meet for training, Mahiru brings another Eve with him: Testu Sendagaya the Eve of the Servamp of Pride, whom Mikuni immediately dislikes after the boy touches Abel out of curiosity, calling him a ruffian. Nevertheless, Mikuni agrees in training him too - but then states that he can only train them for one week. He then challenges the two Eves to knock Jeje's bags off of his head and expose his true face, much to Jeje's displeasure. Mikuni explains to them how a Lead works in his eyes; it is used to bind and control the Servamp. This offended Old Child whose perspective is that it is used to control the Eve instead, which Mikuni retorts that Old Child is being naive. When Tetsu succeeds in knocking Jeje's bags off, Mikuni jumps on his Servamp's shoulders and covers his face, surprised by Tetsu's strength and thinks they'll grow quicker than he expected.
On the second day of training, Mahiru brings Misono along and Misono instantly recognizes his brother and a small fight between Snow Lily and Jeje occurs. Due to the fact that Misono doesn't really want to kill his older brother, Lily is unable to do anything against Jeje, something that Mikuni notices and points out to Misono, telling him not to attack half-heartedly. Furthermore, both Servamps are well aware that Jeje is much more powerful than Lily.
Mikuni then decides to leave and tells Mahiru that society often gives him fitting information and that he should let go of what he isn't necessary and take what he really needs. For Mikuni, there are two things that are required to always be in a good position- information and power. He tells Mahiru that when he was his age, he had both information and power - and thats why Misono still hates him - but he doesn't want to go into detail because he doesn't trust Mahiru enough to give him this information.
The next time Mikuni is seen is when he is talking to Syuhei Tsuyuki who is a former classmate of his, and a member of C3. It is revealed that Mikuni has good connections with the boss of C3, preventing Tsuyuki from hitting him. Mikuni tries to convince Tsuyuki not to recruit Mahiru because it isn't worth it, and once Tsuyuki leaves, it's revealed that Mikuni actually came to stop Mahiru if it seems he is agreeing to work with C3, but after seeing Mahiru, he realizes that it was unnecessary.
Attack on Alicein Mansion
Later on, he feels as if something terrible is happening back at his old home. Since he doesn't want to go there himself, Mikuni asks Tsuyuki to go for him, however Tsuyuki refuses. A bit later, when the Jin are floating out of the house, Jeje asks Mikuni if he really doesn't want to go back there - he states that something could have happened to Misono. But Mikuni then counters Jeje back and asks him if he is worried about Lily. Then, in a hard voice, Mikuni asks Jeje if he really believes he has a say in the matter before saying that he was only joking.
Helping Mahiru and Kuro
Crantz reveals that he bought holy water from Mikuni's antique store, so Mahiru and Kuro visit him in the hope that he is able to help them restore Kuro who is trapped inside a black ball. However, Mikuni had never seen this kind of incident, so instead Mikuni's vampire researcher acquaintance, Johannes, gives Mahiru a drug that allows him to enter Kuro's subconsciousness. Mikuni went out for a bit before returning in panic at Johannes' antics. He then asks about Mahiru but when he saw the paper that Johannes gave to him, he comments that Johannes is weird, but also a genius.
C3 Tokyo HQ
Mikuni's seen again witnessing Tsurugi kill several subclasses. He visits the C3 base and greets Mahiru, warning him to beware of Tsurugi who he reveals to be too dangerous and too broken. When Mikuni meets Tsurugi face to face, they both quickly throw insults towards each other, despite the fact that Mahiru and Syuhei notices that both have some things in common, much to Mikuni's dismay. Then Mikuni suggests to Mahiru that they should kill Tsurugi while they still have the chance, prompting Tsurugi to attack. Then Mikuni orders Jeje not to hold back and attack with intent to kill the magician, but Tsurugi easily disarms Jeje. When Tsurugi places a spell on Kuro so he will be bound to him, Mikuni uses his Lead to strangle Tsurugi to force him to remove his spell on Kuro. Tsurugi doesn't remove the spell and despite clearly on the verge of dying, Mikuni continues to strangle Tsurugi and he seems to lose it until Kuro cuts the tie, saving Tsurugi.
Mikuni and Tsurugi continue with their childish bickering, which is momentarily interrupted by Mahiru who asks if he kills vampires because he also killed his mother, earning a laugh from Tsurugi who points out that it was the truth, angering Mikuni. Before he leaves, Mahiru pleads with Mikuni to meet and speak with Misono later. Mikuni approaches Syuhei and questions him about Tsubaki's subclasses they have captured, and one of them is his father's killer. Mikuni offers his help to get revenge, but Syuhei refuses because the subclasses are needed to lure out Tsubaki. But Mikuni doesn't press the subject any farther, but then he tells Syuhei that revenge can't be done rationally.
During C3's collapse, Mikuni lingers around Mahiru and Kuro, eavesdropping on their conversation, and plans to escape. Once Kuro leaves, Mikuni approaches Mahiru, pretending to not know he was there. Then Mikuni asks Mahiru why he's there and Mahiru tells him he chased after Tsurugi, and now he can't get through the debris. Mikuni states he was just at a control room and that escaped subclass set up a bomb to destroy the facility. He predicts its annihilation in 20 minutes. He mentions that they are most likely Tsubaki's subclass.
Hearing this, Mahiru states that they must hurry to rescue Tsurugi and the others. Then Mikuni tells Mahiru that Tsurugi has lost against the subclass and has fallen to lower levels. Then Mahiru realizes that the way things are going, it will be the worst case scenario. Then Mikuni tells him Tsurugi won't die so easily.
Then Mikuni restores Mahiru's hope by showing him a secret passage leading to Tsurugi. Then he states that there are many hidden passages, and that Tsurugi's probably the only one who knows them all.
Then Mikuni states that he learned a lot from his time with Tsurugi at C3, and that Mahiru can use the passage to go to Tsurugi, but he isn't sure he will return safely. Mahiru insists and as Mikuni agrees, the ceiling begins to fall.
Mahiru and Mikuni are now separated between a wall of rubble. They call to one another, asking if he is alright. Mahiru says he will continue through the secret passage alone, stating he will definitely save everyone. Mikuni says even if he tries to stop Mahiru, he probably won't listen. Mikuni tells Mahiru that he leaves Tsurugi to him.
Then Mahiru recalls instances of Mikuni and Tsurugi's relationship and states that Mikuni's actually worried about Tsurugi. Mikuni is caught off guard at this accusation. Then his expression softens and he says that even with their current relationship and clashing personalities, they have known each other for many years. Then Mikuni's expression changes to a sinister one and states, still behind the rubble, unseen to Mahiru, that he really is worried after all.
Then Mahiru leaves and whistles for Jeje to come to his side. Then it's revealed that Mikuni ordered Jeje to cause the collapse that separated Mahiru from them.
Weapon and Ability
- My Fair Lady - Mikuni's Lead is a rope that connected to his doll, Abel, that he is always carrying. When fighting, a figure of a woman will appear that is holding the rope that connects Abel and its target's neck, and then Abel's weight will become as heavy as the sin of the target, strangling the target to death or in subclasses' case, the target will be strangled until Jeje bites them. According to Mikuni, his Lead can only work against people who've killed humans.

Mikado is Mikuni's father. Mikuni used to have a close relationship with his father, however, this changed after Mikuni finds out that his father betrayed his mother by having an affair with one his home tutors, Misono's mother. Then this led to his mother killing Misono's mother out of jealousy, making him hate his father, something that he has no hesitation to express directly to the said person. Mikado doesn't blame Mikuni for hating him, and accepts it as his punishment that he deserves for betraying his wife and son. Even after Mikuni killed his mother and left the house, Mikado still loves his oldest son and wishes to speak with him properly once more as a family.
Misono is Mikuni's younger half-brother. Mikuni's well aware that despite Misono being the kid from his dad's affair, Misono's not at fault, and he loves him deeply. When they were kids, they had a very close relationship, and they both played together often, particularly chess. Mikuni's so fond of his brother, that he has a photo collection of him that he always carries. His love for his brother is so strong that he killed his own mother to protect Misono when his mom attempted to kill him. This strained their relationship for years as Misono's memories regarding the event were manipulated and he didn't know the truth as a result, thus making Misono mad when they reunite. After knowing the truth, Misono still has mixed feelings about his brother and he isn't yet ready to meet him to sort things out.
Jeje (Doubt Doubt)
Jeje is Mikuni's Servamp with whom he has had a contract with for seven years. Mikuni and Jeje overall have a good relationship despite their differences. Mikuni often lies to Jeje to do what he orders him to do by promising he will give Jeje his blood, a promise that he never keeps yet Jeje always falls for the lie. This always ends up with Jeje shooting Mikuni out of anger and Mikuni simply teases him more. Mikuni also likes to do things without asking for Jeje's permission, leading him to receive the end of Jeje's gun, but Mikuni always has a way to convince him. Jeje's quiet nature also gets him annoyed whenever Mikuni starts getting noisy, usually ditching him for a while until he stops being loud. Despite this, there are times Jeje will listen and carry out Mikuni's order, even without the false promise of drinking his blood. Jeje's decision to accompany Mikuni partly seems due to what happened to Mikuni's mother seven years ago, the event most likely made him feel guilty.
After leaving the Alicein mansion, it was revealed that Mikuni became a member of C3. During this time, he, Tsurugi, and Jeje were a team. They shared a room together and got along well. Tsurugi even describes their time together as "shining days of youth".
When Mikuni returns to C3 at the time Mahiru is there, it's made evident that Mikuni and Tsurugi no longer get along. They both go out of their way to pick fights with one another regardless of the time or place. The fighting between them varies from verbal arguments that can be seen as playful or comical to actually trying to kill each other. Contrasting his actions, Tsurugi often expresses that he's happy to see Mikuni, whether he says that to spite him or if he genuinely means he's up to interpretation. Then he states that Mikuni used to abuse him and order him around in exchange for money. Then Tsurugi says he did anything for Mikuni and that Mikuni was, "wild at that age". Then he looks back at the experience as something positive.
Chapter 51.5 gives more insight to their relationship. It takes place seven years prior to the current story, when Mikuni is 16 years old and Tsurugi 19 years old. The two have dinner together, which they often did at C3, at their first meeting. During the meal Tsurugi tells Mikuni that he knows much more about him than should be comfortable. Tsurugi also states that there's nothing common between their two values.
At this time Tsurugi also reveals that he's jealous of Mikuni. When he posed with the same question, Mikuni denies being jealous of Tsurugi, baffled at the assumption. Mikuni didn't understand how he could possibly be jealous of someone who has nothing. Then Tsurugi tells him that's precisely what he's jealous of, saying that Mikuni's jealous that Tsurugi was able to live with nothing from the beginning.
The chapter ends incorporating both Mikuni and Tsurugi's identical thoughts, which are that it's easy to think of the other as pitiful, but they don't admit it aloud because they know they shouldn't.
During a fight at C3 when Mikuni was still a member, then Tsurugi got injured while protecting Mikuni. Mikuni frantically tells him that he didn't ask Tsurugi to protect him, and that it just causes trouble. Then Tsurugi responds by saying even though he's not good at protecting, he'll be in trouble if Mikuni dies. Later that day, Mikuni orders Jeje to stand by Tsurugi's bed while he's recovering. Mikuni says Tsurugi will misunderstand and be grateful. But Tsurugi's happy to see Jeje by his side and that he's thankful for him.
In Chapter 59 while C3's collapsing, Mikuni encounters Mahiru, who declares that Mikuni's actually worried about Tsurugi, who is in trouble. After hearing this, Mikuni's expression softens and states that despite their current relationship and differing personalities, he and Tsurugi have known each other for many years. Then Mikuni's expression changes to a more twisted and diabolical one as he states he's really worried about Tsurugi after all, probably lying while telling Mahiru this.
