Anko Uguisu

"I wanted to kill you. Of course, my father was wrong for falling in love with you with a family around... But that doesn't mean I was able to understand that. I've only been thinking about killing you for the past ten years. Now, I... 'Revenge or whatever, doesn't matter...'"

- Kyouko Mejiro to Kiku Hoshimi

Kyouko Mejiro (キョウコ) is a private detective who befriended Nazuna Nanakusa in high school, eventually discovering her true heritage as a vampire. On her eighteenth birthday, Kyouko's father, who had been transformed into a vampire, had murdered her mother and attacked her, so Kyouko vaporized him in self-defense. Her family tragedy drove her to despise vampires, setting out to become a highly skilled detective, under the alias Anko Uguisu (アンコ), who plotted to eradicate the entire vampire race as a means to kill Kiku Hoshimi, her father's mistress.

Ten years after her investigations began, Kyouko encountered Kou Yamori, a teenager who Kyouko was aware had been friends with Nazuna. Knowing that the only method to kill vampires was by using their most precious possessions as humans, she became a threat to Kou and his vampire allies while she attempted to claim those possessions, but to no avail. During Halloween, Kyouko attacked her enemies and tried manipulating the hesitant Nazuna to kill her, which, in Kyouko's perspective, would lead to the reveal of vampires' existence. However, in her chance of committing suicide, Kou prevented her from shooting herself, resulting in the first surfacing of Kou's half-vampire self.

Now choosing to abort her plans to live a normal life, Kou and Nazuna sought to search after Kiku for Kyouko's sake. She and her new friends started also researching the nature of Kou's newfound powers, and later on, Kyoko joined them on a trip to Hokkaido, where Kou could make amends with Mahiru Seki while Kyouko settled her differences with Kiku.

Appearance
Anko has brown hair, which she partially ties to a bun or ponytail, and brown, lusterless eyes, over which she wears round glasses that belonged to her father.

Her primary outfit consists of a beige raincoat, under which she wears a dark t-shirt, a black skirt with a zipper, and light-brown boots with heels. She wears black gloves that cover half of one hand each. Later she wears her coat less frequently and cuts her hair short.

As a teenager, Anko wore a baggy blue sailor uniform and a skirt while going to school. Her regular outfit was the same as her current one, and her eyes had light in them.

On Halloween, she wore two different costumes as a disguise. She first dressed like a grim reaper and then like a sexy policewoman.

Personality
Anko is a very straightforward, observant, and sociable woman with a primarily casual attitude who likes to mess around with others.

However, she can change her mood in the blink of an eye and quickly unsettle someone, either by becoming completely serious or displaying her unstable side. In the latter, it becomes apparent that she's got a few screws loose.

Anko has a goofy side that's shown on some occasions, like when she genuinely thinks that Kou wants to be in a relationship with her and subsequently feels awkward when she turns out to be wrong. She occasionally makes dirty jokes and becomes a "sexually harassing geezer" when drunk. Anko is serious about romance and doesn't joke about it. She is starved for a romantic relationship and attracted to both men and women, including middle schoolers. She has little to no self-control when staring at female body parts.



One of her most defining traits is her hatred for vampires. She is ruthless and determined to wipe them out, exhibiting sociopathic behavior. Her actions are sometimes noted to be reckless, with little regard for her own life, like when she attacked two vampires head-on. Anko usually shows no empathy when hurting them and was even shown to be highly sadistic and psychotic as she maniacally laughed while repeatedly stabbing Akkun in the gut.

In the end, Anko was a scarred woman who spent her youth on hatred and killing and wanted to die while taking all vampires with her. Her grudge gave her a purpose in life, which she could only keep by taking her anger against one vampire out on all vampires. Anko thought about killing herself more than once but was afraid of dying and used her anger to give herself a reason to live. After her plan failed, she described herself as "an empty shell" since she could no longer keep up her anger, a "boring woman who has gained nothing but age."

After getting a new chance in life, Anko gave up hunting vampires since she felt tired and regretted her actions for multiple reasons, sincerely apologizing to Nico Hirata for shooting her. Adjusting to a normal life felt difficult for Anko since she had never experienced anything an average adult would, like friends and romance. While she isn't interested in killing vampires anymore, Anko feels more at home in an abnormal life, determined to find Kiku Hoshimi and help Kou. Since the Halloween incident, Anko has become more of a calmed-down analyst who often makes blunt and sarcastic remarks. She still doesn't value her own life much, remarking that any vampire intending to kill her is "free to come."

Despite giving up on revenge, Anko still hadn't healed from her trauma and harbored pent-up frustrations, longing for some satisfaction she couldn't get.

Nazuna Nanakusa
When Anko attended school at night as Kyouko Mejiro, Nazuna entered the literature club room, and Anko welcomed her in. One of her first interactions with Nazuna was almost kissing her while she was asleep. Despite spending most of her time alone, Anko was friendly and welcoming towards Nazuna, and they quickly became friends, with Anko even displaying sexual attraction towards Nazuna.

Anko would recommend books to her. She was often baffled by Nazuna's personality and lack of common knowledge, playing an essential role in shaping Nazuna into the person she became later. Soon, she would entrust very personal information to her, like her father having an affair, and they would investigate it together. Nazuna revealed to her that she was a vampire not long after. Anko eventually broke down in tears because of her pent-up frustrations regarding her family and begged Nazuna for help.

Nazuna tried to make Anko her first servant but couldn't because Anko wasn't in love with her. They wanted to meet again, but after Anko's father turned into a vampire and destroyed her family, she became resentful of Nazuna and left her after a short exchange.

They didn't see each other for years. When they met again, they engaged in small talk regarding their current lives, the conversation marked by an underlying sadness from both parties.

When she met her on Halloween, Anko attacked Nazuna and brutally injured her, including shooting her in the eye. She told Nazuna to stop meeting with Kou as she felt for him and then intentionally tried to bait Nazuna into killing her by threatening to kill Kou. After her plan got exposed, she confessed to Nazuna that if anyone were to kill her, Anko hoped it would be her. She later told Nazuna that she wanted to love her but couldn't.

Afterward, they made up and became friends again. Their dynamic became very similar to the one they had in the past, and Anko still lusts over Nazuna.

Kou Yamori
Anko and Kou first met when he was scouting for potential customers for Nazuna's snooze shop and approached her. Anko teased him by saying he was hitting on her and expressed interest in Kou. She explained that she doesn't necessarily follow the law and, therefore, wouldn't report Kou to the authorities, despite the illegal nature of Kou's job. After talking more, Anko quickly noticed that Kou knew something about Akkun's case but left the place after initially scaring him. She would appear at Kou's school, where she killed a vampire in front of him. Anko knew Kou was dreaming of becoming a vampire, berating him for it since she believed all vampires cause suffering.

Anko explained that she didn't want to hurt him but would be forced to if he remained loyal to Nazuna and said she would protect him from other vampires, offering him to "use her however he wishes." She repeatedly teased him and is genuinely interested in a relationship with him.

Despite threatening to kill him, Anko cares a lot about Kou. She pretended to invite him to her location so she could kill him but actually sent him a message meant to be her last will. In the message, she told him not to look for her and to stay away from vampires. Anko believed that, just like her, he won't be able to turn into one and that he's still young, with a long life ahead of him, even if he remains human. After accidentally shooting Kou, Anko was distraught and started to cry.

After Kou woke up in a hospital and got discharged, Anko apologized for telling him he might be missing the emotion of love, reassuring him that his love for Nazuna was genuine. While drunk, she requested to sleep with Kou. They talked about what defines an adult, and Anko forced Kou to lie next to her. She told him how living a normal life was difficult and cried into his chest.

Kiku Hoshimi
Kiku was the source of Anko's trauma and the person who ruined her life. Kiku was also the cause of Anko's hatred for vampires in general. She developed an obsession with Kiku, so much so that she lost track of her emotions, chasing her for ten years. She was unable to understand Kiku and wanted to know what she was thinking before killing her, but her investigation left more questions than answers. One night, Kiku confronted her in Anko's own office, leaving Anko frightened.



After the Halloween incident, Anko wanted to give up on her chase but changed her mind after being persuaded by Kou and Nazuna. While unsure if she wants to kill her anymore, Anko still wanted to confront Kiku. When meeting her, Anko revealed that her feelings hadn't changed and threw knives at Kiku, piercing her hand. She knew that she couldn't kill her but still did it because she felt annoyed. She proceeded to pour out her bottled-up emotions and tell Kiku everything she had wanted to say for the past decade, breaking down in front of her. Kiku started to remember her name and told her an unreadable confession. Those words made Anko let go of Kiku and watch her walk away.

Abilities

 * Detective skills: As a detective, she is very skilled in finding information about specific people and even stalking them. Whether through deduction or investigation, she described Kou's life and personality with frightening accuracy, including small, trivial details.


 * Knowledge of vampires: Having spent 10 years hunting vampires, she has gained a decent amount of knowledge about them, though there are gaps; for example, she didn't know that vampires could faze through solid objects until Hatsuka Suzushiro demonstrated said ability. Because of her father's death, she knows of their weakness, which is touching something from their human pasts. Even without killing them, she knows of a few ways to survive an encounter with them.


 * Weapon proficiency: She knows how to use throwing knives effectively and used them to attack Kiku Hoshimi. She also knows how to wield a gun, owning a revolver.


 * Foul tasting blood: Since she got her blood sucked by a vampire 10 years before the story started and didn't turn into one, it's now impossible for her to become a servant, which makes her blood repulsive for any vampire who tries to suck it. She is aware of this and uses it to her advantage.
