This page describes the characters in Hell Girl.
- Affably Evil: Ai's teammates have a fairly even-minded opinion of humankind, and happily support their co-workers, students, and friends in their many, many jobs. It almost makes you forget what their real job is.
- Anti Villains: Aside from Kikuri, they're actually pretty decent folks aside from their job.
- Clark Kenting: They don't put on any disguise to infiltrate into their clients' lives (e.g. pretending to be a classmate/teacher/etc.), even when they pose as a number of different roles at the same time. Justified, since they are able to prevent mortals from recognizing them. It becomes a plot point in the third season.
- Color-Coded Characters: The minions' straw doll forms are different colors: black for Wanyuudo, red for Hone Onna, blue for Ichimoku Ren and yellow for Yamawaro.
- Even Evil Has Standards: Played with. They aren't happy when an innocent gets sent to Hell, but have no choice in the matter. Additionally, while their job is to send people to hell, they are contemptuous of deliberate human cruelty; for example, in episode 1, they're disgusted that Alpha Bitch Aya Kuroda, who stole the money Mayumi Hashimoto was entrusted with and forced her into Compensated Dating to make it back, is writing off her behavior as "kid stuff"; and for another example, in episode 16, they sound very angry when telling off Yuki for how she treated her sister Yumi.
- Played Straight in one instance where Ichimoku Ren attempts to prevent a child from sending her own mother to Hell because the mother is already Hellbound due to a previous covenant with Ai, only succeeding when the mother chooses to commit suicide in order to spare her from doing so.
- Hone Onna before she assumed her doll form, directly expressed a particular amount of disgust and anger at a girl claiming to be a fortune teller, who sent an innocent man to hell after being bullied into it by a popular girl in her school to avoid being an outcast.
- Hidden Heart of Gold: Despite their efficiency and cruelty in sending people to hell, they can be quite kind-hearted and sympathetic to the turmoil of others. Not often, this may include gentle nudges to use Hell Correspondence if they believe it would save the person from further suffering.
- As well as stalling for time when the would-be victim is on their deathbed. One may only send someone who is still (technically) alive.
- This is also the only confirmed instance of a character going to Heaven, though, like Hell, it is never seen.
- And in one case, physically stopping a moving vehicle to prevent revenge when the covenant was impossible, after the contract had already been invalidated and there was no obligation to stay.
- As well as stalling for time when the would-be victim is on their deathbed. One may only send someone who is still (technically) alive.
- New Job as the Plot Demands: Ai's minions are often shown with different jobs as they observe a prospective client and the corresponding target before the string is pulled.
- Not So Stoic: Inverted. They are not allowed to have their emotions interfere with their job, but act normally around each other.
- Punch Clock Villains: Very much so. Ai ferries people to hell because that's where her parents will go if she doesn't. Her assistants stay with her out of loyalty.
- Really 700 Years Old: Ai is at least 400 years old. Her first three companions came from various periods of feudal Japan.
- Technically speaking, Ren was 100 years old exactly when he was 'born'. Except, replace "born" with "transformed from a katana".
- Sleep-Mode Size: Their straw doll forms are basically this when someone's not using them to sell their soul for revenge.
- Stealth Hi/Bye: They can go between the sunset realm and the world of the living by just vanishing and will often disappear when some random object or person moves in front of them.
- True Companions: Ren outright says that their little group is like family to him. In season 3, Yuzuki asks Ai who Ren, Honne Ona, and Wanyuudo are to her. Ai says they're her nakama.
- Undying Loyalty: For Wanyuudo, it saved him from running until burning into hell, for Hone Onna, it's because Ai helped them regain their humanity. In the case of Ichimoku Ren and Yamawaro, it's because she saved them from a lonely existence.
- Villain Protagonists: They are the main characters and their job is to carry out revenge on others' behalf and ferry people to hell. That doesn't mean they are evil, though.
- Voluntary Shapeshifting: They can do this to varying degrees.
The titular Hell Girl. It is her duty to offer a devil's deal of vengeance to any who access the Hell Correspondence. If the "customer" accepts, she ferries the target of that person's vengeance to Hell. As part of the deal she will also ferry the "customer" to Hell after he or she dies.
- All of the Other Reindeer: In her backstory, she was ostracized and bullied by the people of her village. It's implied that this is why she was chosen as a Human Sacrifice - the townspeople just wanted to get rid of her.
- Aloof Dark-Haired Girl: Appearance-wise, Ai is a beautiful, doll-like girl with long, black hair who shows no emotion.
- Benevolent Boss: She does care for her minions in her own quiet way and they love her right back.
- Beware the Quiet Ones: Ai's job as the Hell Girl forces her to repress her emotions to the point where it's very hard to make her angry... God help you if you actually succeed.
- Broken Bird: Long ago, she was a normal girl. Then she and her parents were Buried Alive as a sacrifice and she was betrayed by her cousin when he helped to bury her. Her spirit full of hatred returned to get her revenge and her soul was punished by being forced to become the Hell Girl. Now she rarely shows any emotion.
- Buried Alive: How she and her parents died.
- Butterfly of Death and Rebirth: She returns to the mortal world in this form at the beginning of the third season.
- Casting a Shadow: One of her powers.
- Creepy Child: Even before she became the Hell Girl, she was known by most of the villagers as the monster girl who has strange powers.
- Creepy Monotone: When not interacting with her minions.
- Cute Witch
- Dark and Troubled Past: More than 400 years ago, Ai was a human girl living in a remote village near the mountains. She was frequently bullied by other kids, and her only friend was her cousin Sentaro. At the age of seven, Ai was selected to be the Human Sacrifice. However, her parents secretly asked Sentaro to care for her as she lived in the mountains. A few years later, Ai was discovered when a group of boys followed Sentarou into the mountains. Ai and her parents were captured and Buried Alive as punishment. The villagers forced Sentaro to be the first one to shovel ground to the hole. Sentaro's betrayal brought forth an immense hatred in Ai. As the villagers buried her, she vowed to hate them forever even if she dies. A short time later, Ai returned as a vengeful spirit to exact her revenge by burning the entire village to the ground in her wrath. The Master of Hell then captured her parents and made a pact with her: in exchange for her parents not being sent to Hell, Ai should become the Hell Girl to carry out others' revenge as a punishment for her own revenge.
- Dark Is Not Evil: Dresses in black and red, but serves as the Big Good of the series.
- Deal with the Devil: Her duty is to offer these and carry them out.
- Demon of Human Origin: Ai was originally a normal human girl. During her dying breath, she cursed the villagers that sacrificed her and her parents to their mountain gods. That same night, she came back to life and burned the whole village down, killing everyone in it. After that, she was sent to hell, and the Lord of Hell forced her to take the job of Hell Girl or else she and her loved ones would suffer in hell eternally. The job comes with a powerful set of powers, and over the course of 400 years she gains enough mastery of it to be able to confront the Lord of Hell.
- Dying Declaration of Hate: In the final moments of her life as a human, Ai vowed to hate the villagers that killed her and her parents forever, even after her death.
- Eerie Pale-Skinned Brunette: To contribute to her creepy image as the Hell Girl, Ai has long black hair and ghostly pale skin.
- Emotion Suppression: Despite coming off as an Emotionless Girl, Ai does have emotions, but she must repress them in order to carry out her job as the Hell Girl.
- Et Tu, Brute?: Her cousin and Only Friend Sentaro betrayed her when he gave in to the pressure of the townspeople, did nothing to save her and her parents and even helped the villagers to bury her alive.
- Even Bad Men Love Their Mamas: She serves as Hell Girl because the Master of Hell threatened to send her parents to hell if she refused.
- Everyone Has Standards: She will send most people to hell without blinking an eye. But she was not happy when an innocent young nurse, who had committed no crime, was sent to hell by a drug addict for no reason at all.
- Expy: Serves as an expy to Pinhead from Hellraiser. Both wear black and serve to punish a (usually deserving) human. Also, both work for the forces of Hell and are the antiheroes of their respective franchises.
- The Ferry Man: She ferries people to Hell in a similar manner to Charon.
- Flower Motifs: Lycoris, also known as red spider lilies. They're closely tied to the theme of death, growing near cemeteries and meaning "Those who cannot return" in flower language.
- Ghostly Goals: Revenge. She killed the villagers who used her as a Human Sacrifice. Unfortunately for her, the spider noticed and made her the Hell Girl as punishment.
- Godiva Hair
- Heroic Sacrifice: When she refuses to transport the soul of Takuma Kurebayashi, whose life situation somewhat mirrored her own. As a punishment she becomes mortal and later dies while trying to defend the boy from violent townspeople.
- Hime Cut: It's meant to give her the air of a traditional miko... but in a rather dark and unsettling sense.
- Human Sacrifice: Her backstory; Ai was meant to be this as a little girl, but with Sentaro's help she was able to stay alive even when abandoned in the mountains - until the villagers found out and took it upon themselves to bury her alive along with her parents. In revenge, she rises from her grave and burns down her village, and is made into the Hell Girl as punishment.
- Ironic Hell: She was forced to become the Hell Girl as punishment for burning her village down in revenge for her death.
- Kill It with Fire: Upon returning to life as a demon, she burned her village down and killed everyone in it.
- Kissing Cousins: It's implied she had romantic feelings for her cousin Sentaro, which made his betrayal even more painful for her.
- Meaningful Name: Enma is the Buddhist god who rules the underworld. Ai is that word for love, probably. It's deliberately always written in kana, so we can't be sure which meaning of ai her parents had in mind. There are hints that the "indigo" meaning is significant: the second season finale is called "Aizome" ("dyed in indigo"), as is the end theme, which Mamiko Noto herself sings.
- Not So Different: After burning her village down in revenge, she insists that she did nothing wrong.
- Not So Stoic:
- The first instance of a person being sent for no reason whatsoever, has her usual lines in the ferry scene spoken in an audibly-cracking voice. Then she reaches "this is vengeance", and has to pause before finishing the rest.
- Whenever she finds something related to her past, Ai lets her buried emotions and old resentment get the best of her.
- Parents in Distress: The Lord of Hell is holding the souls of her parents hostage, ensuring she does not go against her duties as Hell Girl. Their souls are freed at the end of the second season.
- Psychopomp: Among other duties, Ai ferries damned souls to eternal torment.
- Rapunzel Hair: Her hair flows down to her waist, and is longer than any one else's in the series.
- Raven Hair, Ivory Skin
- Really 700 Years Old: She has been the Hell Girl for four centuries.
- Red and Black and Evil All Over: Her Sailor Fuku has these colors.
- Red Eyes, Take Warning: Her blood-red eyes are her most striking feature. In life, she actually had brown eyes, but they turned red the moment she swore her revenge upon her village as she and her parents were buried alive.
- Roaring Rampage of Revenge: After the townspeople buried her alive along with her parents, she came back and burned the entire town to the ground in retribution, leaving no survivors.
- Rei Ayanami Expy: Red eyes, really pale skin, supernatural nature, troubled past and an emotionless demeanor that can be quite unsettling.
- Sailor Fuku: Wears a black one when not in her ceremonial kimono.
- The Stoic: She is forbidden from showing emotions by the spider.
- Stringy-Haired Ghost Girl: A variation. She's definitely onryo-inspired, but she's less scary most of the time because her hair doesn't obscure her face.
- Sugar-and-Ice Personality: She appears emotionless at first glance, but Ai is actually forced to repress her emotions in order to carry out her job as the Hell Girl. She allows herself to show a more caring and compassionate side around her True Companions during their heartwarming moments. Also, she can show sympathy to her clients, especially those who were betrayed by others. This is because betrayal featured strongly in the incident that led her to become the Hell Girl.
- Tranquil Fury: She is quiet and wouldn't raise her voice, even when she's on a vengeful rampage against the people who made her angry.
- Unmoving Plaid: The patterns on her kimonos. In the third season you can see the objects in the pattern float back and forth.
- Used to Be a Sweet Kid: There was a time in which Ai was a sweet and innocent little girl. After the villagers sacrificed her and her parents to their mountain gods, her cousin betrayed her and she was forced to become the Hell Girl, Ai became an Emotionless Girl that keeps her emotions and pain hidden most of the time.
Ai's first assistant. He can appear as a fiery wheel or as an elderly gentleman wearing a fedora. He also serves as Ai's transport to banishment victims.
- Badass Grandpa: Usually appears as an old man while investigating the human world, but he is still a demon who is strong enough to bare-handedly stop a moving truck.
- Bald of Evil: Subverted. He's an agent of Hell, but he is otherwise a very moral person.
- Berserk Button: Thoughtless and unjust crimes, such as a father allowing his daughter to be raped for humiliating him, when it wasn't at all her fault.
- Big Damn Heroes: He does this for the above-mentioned girl in the second season, scaring off her would-be rapists by charging at them in wheel form.
- The Big Guy: He's the only one of Ai's assistants who is shown to have Super Strength.
- Big Ol' Eyebrows: Larger than anyone else's, at least.
- Eyes Always Shut: In his human form, though we do see them open during a flashback of how he met Ai.
- Nice Hat: A fedora, in contrast to to his casual Japanese attire.
- Only Known by Their Nickname: While Hone Onna's name while she was alive is known, Wanyuudo is only known by his nickname since he is a tsukumogami.
- Playing with Fire: He can appear as a giant fiery wheel with his face as a hubcap. In his human form, he can throw fireballs.
- Skintone Sclerae: Shown to have these in a flashback.
- Super Strength: Futakomori shows him stopping a speeding truck.
- Voluntary Shapeshifting: He can transform into a giant fiery wheel. During banishments he can transform into any object with wheels.
- Was Once a Man: Inverted. Before getting turned into a yokai, he was the left wheel of a carriage during the Heian Period. After the carriage was destroyed and burned, he became a fiery wheel monster.
Ai's second assistant. He appears as a young man, though he can transform into a blue straw doll when he needs to deliver vengeance. Can transform into a large eye, which he often uses to spy on the humans.
- Berserk Button: Abusive relationships, and when the Hell service is used on people who don't deserve it.
- Big Brother Instinct: He can act this way towards some of the clients.
- Bishōnen: Has an appearance of a handsome young man, and has occasionally used seduction to get information from female clients.
- Color-Coded Eyes: A shade of yellow-green, which is striking amongst the regular Japanese populace. His large eye is also this color.
- Eye Spy: He can project his eye anywhere he wants, and this makes a very useful spying tool.
- Faceless Eye: He can spy on people by projecting an eye onto any surface or simply appearing as a giant eye.
- Hot Teacher: He is a science teacher in the third season.
- Louis Cypher: Ren Ishimoto.
- Peek-a-Bangs: His hair covers the part of his face where his left eye would be.
- Sympathetic Sentient Weapon: As a tsukumogami, he was a sword that became sentient after one hundred years. Because he was still an inanimate object, he was Forced to Watch as people used him as a weapon of both war and murder. He had been left behind after a battle and was stuck there until Ai found him.
- Villain Teleportation: He can use his eye for this rather than just teleporting like the others.
- The Walls Have Eyes: He normally spies on people from walls and ceilings.
- Youkai: A tsukumogami, though the name and the eye may be a reference to Mokumokuren.
One of Ai's assistants. Her appearance is that of an attractive woman in a blue kimono. When interacting with humans, she normally wears a formal suit.
- Aloof Dark-Haired Girl: She's tall, dark-haired, beautiful, graceful and aloof.
- Berserk Button: Thanks to how she became a youkai, people betrayed by loved ones. An episode involving a woman who manipulated and eventually murdered a girl shows that she doesn't like betrayal in general.
- Cool Big Sis: To one client especially.
- Dark and Troubled Past: She was originally a young woman named Tsuyu, who was sold into prostitution by her lover to pay off his debts. When she tried to plot an escape for her fellow prostitute Kiyo, she betrayed her and had her killed. When her corpse was thrown into the river filled with bones, the spirits fused with her body, becoming Hone Onna.
- Dem Bones: Being based off the mythical youkai of the same name, she can make any part of her skeleton visible.
- Eerie Pale-Skinned Brunette: Hair black like the night and skin pale like a ghost. A look fitting for a Youkai made from several resentful souls.
- Even the Girls Want Her: In season 3, we discover that she has many female students fawning over her and vying with each other for her attention.
- Hair Decorations: She has at least one hairpin, comb, and ribbon in her "true" form. With each season she seems to add more.
- Hooker with a Heart of Gold: In her backstory.
- Hot Teacher: She is a gym teacher in the third season.
- Iconic Outfit: While in the world of the living, she usually wears a business suit that is the same shade of red as her straw doll form. Ai wears it during one of Futakomori's Hell Banishments.
- Impossibly-Low Neckline: On her default outfit.
- Knife Nut: She is a very skilled knife thrower.
- Louis Cypher: Anna Sone.
- Meaningful Name: Tsuyu, the name she had back when she was human, is based on Otsuyu, the name of the Honne Onna of a popular Japanese tale.
- Ms. Fanservice: She has worn a nurse outfit more than once.
- Nightmare Face: When she shows her skull. Done more effectively in the live-action adaptation.
- The Power of Hate: It was the hatred of other betrayed women that made her into Hone Onna.
- Reflectionless Useless Eyes: Her eyes don't reflect any light to emphasize she's a Youkai.
- Unkempt Beauty: Notably with her loosened kimono and slightly disheveled hairstyle.
A mysterious little girl introduced in the second season. She delights in annoying others.
- Bratty Half-Pint: Very much so, though Yamawaro keeps her in check in season 3.
- Creepy Child: Mostly in season 2.
- Creepy Doll: Averted. In the third season, she possesses a wind-up doll and is no creepier because of it. Her having to be wound up again is a running joke.
- Demonic Possession: The spider possesses her at the finales of the second and third seasons.
- Flower in Her Hair
- Kick the Dog: She is directly responsible for a couple of Cruel Twist Endings in Futakomori.
- Kids Are Cruel: In season 2, she would sometimes go out of her way to make people who made contracts with Ai regret it while they were alive. Case in point: a man who stole money for his wife's medical care banished the person blackmailing him over it, so she made the wife forget him.
- Meaningful Name: It's a reference to Kikuri-hime, the Shinto goddess in charge of communicating with Yomi, the land of the dead.
- Purple Eyes
- Supernatural Is Purple: Very much so.
- Token Evil Teammate: While the others are Affably Evil and Punch Clock Villains, Kikuri is never a kind girl and is more sinister than they.
- Troll: Enjoys bothering the other minions and occasionally people she meets in the world of the living.
- Running Gag: In the third season, Kikuri has a wind-up key on her back, which needs to be re-wound repeatedly.
- Unwitting Pawn: From Futakomori onward, the spider is using her to observe Ai's actions.
One of Ai's assistants. He was introduced in the third season and had the appearance of a boy. Most of the time, he keeps Kikuri from bothering the other minions. At the end of the fourth season, he becomes Michiru's first assistant when she becomes a Hell Girl.
- Blow You Away: He has some control over wind.
- Foil: To Kikuri. Where Kikuri is bratty and immature, Yamawaro is very polite and stoic.
- Intrigued by Humanity: Shown to be this in his backstory. It's what caused him to approach Hikaru's parents and start to live a normal life. He eventually starts working for Ai for much the same reason.
- Keigo: He has a rather polite speech pattern.
- Mushroom Man: Before he met people, he was a mass of mushrooms with a human face. One of the people he lived with cultivated the fungus for an elixir of life, so he still has fungus inside his body despite appearing human.
A kindly old woman hidden behind a sliding door who only speaks to Ai. All that is seen of her is the silhouette of an old woman with a spinning wheel.
- The Faceless
- O.O.C. Is Serious Business: She only ever talks to someone other than Ai twice. The first is when she gets Hajime to stop Ai from giving Tsugumi the straw doll. The second is when she thanks Ai's minions for all they've done for Ai.
- She Who Must Not Be Seen: The audience never gets to see her true appearance. The only character who actually does see her freaks out, suggesting that this is a good thing. In the live-action series, she opens the sliding door at one point and nobody is visible behind it.
A bumbling reporter who has made it his mission in life to stop Hell Girl. A book written by him appears in the second season.
- Bumbling Dad: At times, he seems like an older brother to Tsugumi rather than her father. It's clear that in some areas he still has plenty of growing up to do.
- Disappeared Dad: From the second season onward. It's revealed that Hajime and Tsugumi gradually drifted apart and lost touch; and in Season 3 she confides to Yuzuki that she no longer has any idea of where he is. She does recall that he simply became "tired" of trying to stop people from condemning themselves to hell in the name of revenge. Ai and her minions haven't seen him either, so he's not in Hell, but that's all we know.
- The Ghost: From Season 2 onward. He disappeared after writing a book about Ai, and not even his daughter knows where he is.
- Failure Hero: This guy MAY have had one success in the whole time he tries to keep people from pulling the red string (the ending of that episode involving the daughter of his old friend and their failing farm was ambiguous). Sure the youkai will take some action to keep him from interfering, but in the vast majority of the cases he's either too late or else he says the wrong things that just end up ticking off the curse doll owner by coming across as very preachy.
- Inspector Javert: He can be aggressive in trying to keep people from using the Hell Correspondence.
- Intrepid Reporter: His job until Tsugumi starts having visions.
- Married to the Job: This is what made his wife start cheating on him.
- My Greatest Failure: His wife's death.
- Parting Words Regret: Regarding the last words he spoke to his wife before her death.
- Sins of Our Fathers: Near the end of the first season, Ai tried to kill Hajime and Tsugumi because they are descendants of Sentaro. When that didn't work, she tried to bully Tsugumi into banishing Hajime to hell. It is also possible that Ai simply mistook Hajime for Sentaro.
- Tall, Dark, and Handsome: He's pretty attractive.
- Thou Shalt Not Kill: A thorough believer in this, unfortunately for him this series deconstructs it. The people he tries to stop, can't relate to him telling them that killing is wrong. They're often in great emotional pain that's RECENT and have their intended target taunting them constantly about it, or they know that they're trapped in a 'kill or be killed' situation and having a complete stranger who doesn't know the context only alienates them from his point of view. It gets to the point that even his daughter dismisses him.
- Well-Intentioned Extremist: His attempts to stop people from making deals with Hell Girl can fall into this.
Hajime's young daughter. She is able to see through Hell Girl's eyes.
- Age Lift: The anime introduces her as a little girl, but in the live-action adaptation she's already a teenager.
- Blessed with Suck: See Forced to Watch below.
- The Cameo: She is seen as a slightly older schoolgirl near the end of the second season when she tells someone about the book her father Hajime wrote before he disappeared.
- Curtains Match the Window: Her hair and eyes are both brown.
- Dead Person Conversation: Every conversation she's had with Yuzuki is revealed to have been one.
- First-Name Basis: With her own father. Some of their interactions actually make them seem more like siblings.
- Forced to Watch: She is somehow able to see through Ai Enma's eyes as the Hell Girl meets with her clients, and she uses this ability to help Hajime track the clients down. She keeps this ability as an adult.
- Girlish Pigtails: Usually, though she's known to have different hairstyles from time to time, such as Odango Hair.
- Hair Decorations: A round barrette to pin her braid. Before the school nurse was officially revealed to be an adult Tsugumi in season three, this was the viewer's hint to her identity.
- Letting Her Hair Down: She wears it this way as an adult.
- Lonely Piano Piece: Her theme in Mitsuganae is a sad piano piece, reflecting her mental state after having given up on stopping the Hell Correspondence and knowing that she can do nothing to help Yuzuki.
- Missing Mom: Her mother died in an accident after an argument with Hajime, while Tsugumi was still a toddler. This becomes a plot point in the finale of the first season.
- School Nurse: In the third season, she is the nurse at Yuzuki's school.
- Screw Destiny: In season three, Yuzuki believed Tsugumi's visions meant that she was fated to become the next Hell Girl, and she had managed to escape it.
- Subverted. She lets it hang for an episode or two, then tells Yuzuki that she was never intended to be the next Hell Girl and You Can't Fight Fate.
- Sins of Our Fathers: Ai tried to kill Hajime and Tsugumi because they are descendants of Sentaro. She then tried to bully Tsugumi into banishing Hajime to hell. It is also possible that Ai mistook Hajime for Sentaro.
- Tragic Keepsake: Her mother's earrings, which she wears on a pin.
Hajime's dead wife. When he caught her cheating on him, he chased her away, resulting in her dying in a car crash.
- Driven to Suicide: It's heavily implied that she drove into the pole on purpose, after Hajime refused to forgive her or let her see Tsugumi.
- Parental Neglect: Hajime accused her of this when she went out with the man she cheated on him with at night, leaving Tsugumi alone.
- Posthumous Character
- Your Cheating Heart: She began cheating on Hajime when his work began taking up most of his life. He caught her cheating on him with a man he was investigating.

- Ironic Hell: While being ferried to hell, he is tortured by demonic representations of people he murdered.
- Mind Rape: Does this to the Phony Psychic who eventually sends him to Hell as well as to Hajime.
- Not So Different: He thinks that he and Ai are similar. He's right, but not in the way that he thinks. While they both have supernatural powers, their abilities are quite different. The similarity lies in the fact that they avenged their own deaths by killing those responsible. Ai is visibly angered when he brags about it.
- Psychic Powers: He has telepathy and telekinesis among others. His powers allow him to see the Hell Girl when she appears.
- Self-Made Orphan: He claims his parents and teachers murdered him first and that he killed them in revenge after breaking out of hell. This monologue gets him a Death Glare from Ai.

- A Form You Are Comfortable With: In his first meeting with Ai, he appears as a spider, then possesses the jellyfish floating over the gates of hell, suggesting that they are avatars of a far more powerful being.
- God of Evil: He gets so little screentime that whether he actually is this or not is up to interpretation.
- Ironic Hell: Considers making Ai the Hell Girl a form of this.
- Red and Black and Evil All Over
- Satanic Archetype: Subverted. He rules over Hell and make deals for people's souls, but is a lawful being in that there are strict rules about who may be sent to Hell and may just be doing his job.
- Suddenly Voiced: At the end of season one.
Ai's cousin and only friend.
- The Atoner: Builds a temple on the place where Ai was buried.

- Peer Pressure Makes You Evil: He was forced to betray Ai by the villagers, who blamed them both for the famine that was making them starve.
- Token Good Teammate: The only villager besides Ai's parents that didn't make Ai's life hell.
The people who lived in Ai's village when she was alive, 400 years ago.
- All of the Other Reindeer: They made an innocent girl's life a living hell for no reason.
- Asshole Victim: They paid dearly for their horrible mistreatment of Ai.
- Buried Alive: How they sacrificed Ai and her parents.
- Create Your Own Villain: As they buried Ai and her parents alive, her hate for them because of their cruelty toward her became so powerful that it allowed her to come back to life as a demon and slaughter them all.
- Cruel and Unusual Death / Karmic Death: Burned alive in their homes by the young girl they tormented without end and ultimately killed. Needless to say, they deserved every second of it. And the one-way express trip to hell they very likely got afterwards.
- Evil Is Petty: Lets face the facts, they targeted an innocent girl and her family simply for being a little weird. Thats it. They condemned her and her family to death over something as ridiculous as simply being different.
- Human Sacrifice: They held a tradition of killing children to appease a mountain god.
- Infant Immortality: Defied. Ai spared no one except Sentaro, who was running away at the time, when she burned down the village.
- Kids Are Cruel: And teenagers, and adults, and elders...
- Kill It with Fire: How they meet their end when Ai decides to liquidate the lot of them for their transgressions, via turning the village into a firestorm.
- Kill 'Em All: Their ultimate fate at the hands of Ai. Good riddance, too.
- Posthumous Character: They are all dead in the present day and their role in Ai's backstory is told via flashback in Episode 25.
- Religion of Evil: Sacrificing their own children to a mountain god? One gets the impression that they weren't great people even before Ai was born.
- Self-Fulfilling Prophecy: They ostracized Ai because she was believed to have supernatural powers. Their final and most monstrous act of cruelty toward her—burying her alive along with her parents and forcing her beloved cousin to betray her—made her hate of them so strong that she transformed into a demon, clawed her way out of the grave they dug for her, and sent the village up in flames, taking them with it.
- Town with a Dark Secret: Just a peaceful Japanese farming village that sacrificed little girls to please their mountain god and indirectly created Hell Girl as we know her. Nothing to see here.
- What Happened to the Mouse?: Although we see them die, their fates after death are unrevealed and it is unknown if they went to hell (although they probably did).
- Would Hurt a Child: Would kill a child, in fact. The village had a policy of sacrificing young girls to their mountain god to ensure plentiful harvests. Ai was the last of them.
A boy who lives in the town of Lovely Hills. He is blamed for murdering his mother and assaulting his father due to being in the wrong place at the wrong time in both cases. When people begin disappearing around town, the townsfolk blame him. As the disappearances continue, people begin to fear that he has supernatural powers and begin calling him the "Devil's Child."
- Age Lift: He's very young in the anime, about primary school age (or middle school, at most). The manga turned him into a high schooler.
- Dragged Off to Hell: Ai couldn't bring herself to do this to him.
- Frame-Up: Good heavens. After being falsely accused of murder, people who use the Hell Correspondence blame the resulting disappearances on him.
- Not So Different: From Ai, which was why she couldn't bring herself to ferry him to hell.
- Red Baron: Subverted. People began calling him the Devil's Child for things that aren't even his fault.
The younger sister of the detective investigating Takuma. She befriends him after finding out that he isn't responsible for the disappearances around town.
- Despair Event Horizon: After her brother gets banished, she tried to banish Takuma and then drown herself so she can join them in hell.
- Driven to Suicide: After attempting to banish Takuma, she wades out into a lake so she can freeze to death and be with Takuma in hell. She survives, but is hospitalized.
- Freak Out!: When Kikuri brings her to Ai's hut, she looks behind the sliding door and gets a good look at Ai's "grandmother." She runs away in terror. Then Kikuri drags her behind the sliding door again.
- Heroic BSoD: When her brother is banished, she accesses the Hell Correspondence. She thinks that with Takuma gone, things in her hometown will calm down.
- Only Friend: To Takuma.
A middle school student who gets possessed by Ai Enma. As a result, she has the ability to see the grudges avenged by Ai in much the same way as Tsugumi did. It goes downhill from there.
- Ascend to a Higher Plane of Existence: Yuzuki goes to heaven after Ai becomes Hell Girl again.
- Blessed with Suck: Much like Tsugumi, she can tell when Ai is about to make a contract, but is unable to do anything about it.
- Break the Cutie: Her backstory. She was an adorable Cheerful Child living happily with her parents; then her father - a bus driver - died in an accident while on duty and she and her mother wound up as pariahs because it was ruled that the accident was his fault. They were eventually driven out of town and took refuge in a shrine, where Yuzuki's mother succumbed to an illness. Left alone, Yuzuki herself died of either starvation or a broken heart.
- Call-Back: A fairly obscure one in the final episode. Yuzuki's Hell Girl kimono has a flower pattern that was displayed on Ai's kimono at the beginning of season two's credits.
- Casting a Shadow: She is able to do this after replacing Ai as the Hell Girl.
- Dead All Along
- Forced to Watch: The same way as Tsugumi, though for an entirely different reason.
- Hair Decorations: That one little barrette at the side of her bangs.
- Innocent Blue Eyes: When she finally embraces her destiny as the next Hell Girl, they turn red just as Ai's had been.
- Invisible Parents: She talks to them over the phone from time to time, but they're never seen. The reason they're never seen is because, in reality, they're just as dead as she is.
- The Mirror Shows Your True Self: Played with. Ai is shown where Yuzuki's reflection should be, revealing her presence and connection to Yuzuki.
- Ordinary High-School Student: Subverted. For one thing, she didn't live long enough to make it to middle school, let alone high school.
- Screw Destiny: She tries so hard to stop people from using the Hell Correspondence, but fails every time. She also couldn't avoid becoming the next Hell Girl.
- Soul Jar: For Ai for the first half of Mitsuganae. They still have a supernatural connection after they are separated.
- Screw the Rules, I Have Supernatural Powers!: After becoming Hell Girl, she tries to banish Azusa to avenge Akie. She nearly got sent to hell for it, saved only by Ai intervening and becoming Hell Girl again.
- You Can't Fight Fate: No matter how hard she tries.
Yuzuki's classmate and best friend.
- Attempted Rape: Azusa sends a man after her while Akie's taking a shower. Luckily, her father saves her.
- Dragged Off to Hell: Azusa sends her to hell to punish her father.
- Ordinary High-School Student: She's not affiliated in the Hell Girl business in any way, and serves as the only link Yuzuki has to a normal life.
- The Bus Came Back: Somehow, she returns from Hell in order to be Yuzuki's servant after Yuzuki takes over as Hell Girl.
- Subverted - it's not actually her, just an illusion created by the spider.
- Bitch in Sheep's Clothing: Pretended to befriend Akie, with every intention of betraying them.
- Deal with the Devil: She sent Akie to hell to make her father suffer for covering up a crime. This comes back to bite her when Takasugi's maid does the same to her.
- Dragged Off to Hell: Mr. Takasugi's maid is ultimately the one to banish Azusa and avenge Akie at the end of the finale.
- Even Evil Has Loved Ones: She cares very much for her ailing father, and spends her free time tending for him. This is why Akie's father couldn't bring himself to send her to hell.
A new character introduced in the fourth season who has apparently lost her memory. She is trying to convince Ai that her work as Hell Girl is wrong. As of the end of the season, she has agreed to become a second Hell Girl with Yamawaro as her assistant.
- Adult Fear: First your child is blamed for the accidental death of three bullies who tried to kill your child. Then, she disappears without a trace for days and no one in the village would help you to search for her. And when you finally find her, exhausted but alive, you get locked in the same place your child was and the place is set on fire...
- Broken Bird: Michiru was a genuinely sweet and happy young girl, until her father angered the landowner and it all went downhill from that moment.
- Color Contrast: Michiru's clothes, eyes, and hair are green in contrast to Ai's Red and Black and Evil All Over, signifying Michiru's opposition to the Hell Correspondence. And she gets a green kimono as a newly-minted Hell Girl, which is still fitting since she is still far kinder and more personable with clients than Ai is.
- Dark and Troubled Past: Michiru had a good life and loving family until her father angered the landowner by being held in higher regard than the landowner himself. When the landowner's son tried to drown Michiru in a pond but drowned himself, Michiru is blamed for the incident and her whole family was shunned. It wasn't enough for the villagers though, so they locked Michiru in a shed with no food or water for over ten days. When Michiru's parents finally found her, the villagers murdered Michiru's father in front of her and then set fire on the shed to kill Michiru and her mother for good. With her dying breath, Michiru cursed them and burned the entire village to the grounds. Even worse, she's now just as damned as Ai is for taking revenge.
- Dying Declaration of Hate: Powerful enough to burn the entire village and every single villager.
- Foil: To Ai. For all their similarities, Michiru is a noticeably kinder Hell Girl than the cold and distant Ai and still seems to have faith in humanity.
- Identity Amnesia: She doesn't start to remember her life or even her name until episode five.
- Kill It with Fire: Michiru's neighbours lock her family in a shed and set it on fire, hoping to get rid of them for good. It ends VERY BADLY for them as Michiru, with her dying breath, uses said fire to kill every single one of them and then the entire town.
- Not So Different: She's like both Ai and Takuma in different ways. Like Takuma, she was persecuted and shunned for deaths she didn't cause. Like Ai, she and her family were murdered by their persecutors and both cursed their murderers with their dying breath. Both acts killed everyone in their communities and they're both damned for their vengeance.
- Red Eyes, Take Warning: Her eyes turn red when she finally becomes a Hell Girl.
- The Conscience: She's trying to be this, telling Ai that what she's doing is wrong and once telling one of Ai's clients that she doesn't need the Hell Correspondence.
- Used to Be a Sweet Kid: Cute and lovable human girl, who even said that she will keep always smiling because smiles make people happy. It all crashes down after she is blamed for the death of three bullies who died while trying to drown Michiru in the pond.
