The protagonist of the series. She is the twelve-year-old gravekeeper of her little village, having been given the role when her mother Alfa passed away. Her peaceful life is torn apart when a man named Hampnie Hambart comes to her village and massacres everyone but her. After confronting him, she starts to travel with him, believing he knows something about the truth of her village that he isn't telling her.It turns out that he is her long-lost father, and after they manage to reconcile, he dies and she buries him. Afterwards, she decides to save the world that God has abandoned, and thus begins to travel the world with her new companions.
Adaptation Dye-Job: Compared to the light novels, her hair is a darker shade of gold in the anime.
Compressed Hair: Somehow she manages to fit all that hair underneath her gravekeeper hat.
Disappeared Dad: Her mother told her that her father was named Hampnie Hambart. When a man bearing that name comes to her village, he says it's not possible for him to be her father. Much to his surprise, he actually is.
An immortal gunslinger known as "The Man-Eating Toy," and the one who slaughters Ai's village. Since he knows more about her village than he lets on, Ai follows him, hoping to learn the truth. She also believes him to be her long-lost father, which he denies. He is searching for a woman named Hana.He also desires death above all else, fearing that he may someday be the last living human being in the world, and he wants a happy death surrounded by his friends and family. His lover Hana turns out to be Alfa, Ai's mother, and after being captured and tortured by Hiko and his undead followers, he learns that Ai really is his daughter, and because he is bleeding to death while with family (Ai) and a friend (Julie), his wish for a happy death comes true and he dies for real. After spending a day with Ai as an undead, she buries him beside his lost lover.
Abusive Parents: While he is unaware that he is Ai's father, his initial treatment of her is undeniably child abuse.
The Ageless: He hasn't aged at all since he became immortal at age seventeen.
Meaningful Name: In-series, "Hampnie Hambart" is the name of a toy that kept working even after it broke, and it's implied he took that name for himself when he became immortal. He also tells Ai it's likely her mother took that name from the same toy.
His real name Kizuna can mean "bonds," and the bonds he shared with Julie and Ai happen to be the cause of his death.
Noble Demon: Hampnie unapologetically massacres Ai's village and is very cruel, but he also answers all her questions and requests her services as a gravekeeper for his victims, and assists her with her duties while she is unconscious.
A true gravekeeper. She is polite and always smiling, but she has no emotions and her only role is to bury the dead. After Hampnie dies, she joins Ai on her journey.In Ortus, she adopts Ulla's twin sister Celica, who has been frozen in time and is still a baby. Scar then starts to experience emotions, which leads to an identity crisis. She later comes to terms with her newfound emotions, having become human.
Born as an Adult: Gravekeepers are "born" as adults when they come down to Earth.
Happily Adopted: In Ortus, the baby Celica is quite happily adopted by Scar.
I Have Many Names: Gravekeepers don't have much of a need for a personal identity, and when Hampnie asks her name, she has a long list of names she has been called. However, in the manga, when Hampnie tries to call her something else, she's quite insistent that he calls her Scar. This becomes Fridge Brilliance when we learn that gravekeepers are usually "born" as groups of identical individuals, and having even just a small scar would set a gravekeeper apart from their identical "siblings," and this foreshadows Scar's eventual identity crisis.
Super Strength: A trait of gravekeepers. She can flip grown men one-handedly and without breaking a sweat.
What Is This Feeling?: After adopting Celica, she starts experiencing human emotions, and this leads to an identity crisis. She runs away to Story Circle, the place where gravekeepers are born, and when Ai and the others find her, Julie promises to protect her and Celica, and she rejoins them, having wished to become human.
Hampnie's childhood friend. He was happily married with a wife and a daughter, but seven years prior to the start of the series, his wife died of an illness, and he hid her from the gravekeepers for a year until Hampnie found them and destroyed her body. A month before the series, his daughter also died of an illness, and after a gravekeeper buried her, Julie decided to hunt down Hampnie for revenge. However, because he knows of Hampnie's immortality, Hampnie deduces that what Julie truly desires is to be killed by him.Despite his hatred for Hampnie, he does help Ai save him from Hiko, and his presence helps give Hampnie the death he wants, since he still saw Julie as a friend. After Hampnie is buried, Julie joins Ai on her quest to save the world, acting as her guardian and protector.
Death Seeker: Due to the pain of losing his family, he initially wants to die for the sake of revenge, believing that will give his death more meaning than simply killing himself, and he knows he can't win against the immortal Hampnie. After Hampnie dies, he regains his will to live and acts as a guardian to Ai.
Declaration of Protection: After finding Scar when she runs away to Story Circle, he promises to protect her and Celica. When Ai and Alice think that sounds like a proposal, he also adds that he'll protect them too.
Icy Blue Eyes: At first, before he starts to warm up to Ai and the others.
Spell My Name with an S: Is it Julie or Yuri? "Dmitriyevich" is about as Russian as you can get, but his given name in katakana is spelled differently (ユリー) than the Russian male name usually is (ユーリ). In fact, ユリー is usually how the feminine German name Julie is spelled in Japanese, and since "Sakuma" is a Japanese surname, it's likely his name is meant to be a combination of different ethnicities. In any case, the official subtitles spell his name as "Julie."
Suicide by Cop: His true goal when he attacks Hampnie, although Hampnie refuses to kill him.
Ai's mother and the first gravekeeper. She passed away a few years before the series begins. Unusually for a gravekeeper, she desired to create a Heaven on Earth for the deceased, and the village she tended was composed entirely of those who had died. One of her previous names was Hana, the same as the woman Hampnie is looking for.
A government official from Ortus, the city of the dead. Ai and the others first meet him after he was nearly killed by bandits, and he invites them into Ortus. He is also the tutor to Ulla, the princess of Ortus. He believes she will be the one to save the world.
Artificial Human: He is made from the body parts of five different people, who had asked a witch to grant them a child. He ages more slowly than other humans, and he's not quite living or deceased, as Ulla's Deadly Gaze doesn't work on him while Scar never tries to bury him.
The princess of Ortus. When Kiriko introduces her to Ai, they quickly become close friends. She is often seen in long robes with her face completely covered, and she communicates through Kiriko and writing.She is also the Idol of Murder and the only living being in all of Ortus. When she was born, her resentful mother wished for all humans to die, and while the unborn Ulla unconsciously accepted that wish, her twin sister Celica rejected it. Celica was thus frozen in time and is still a baby, and when Ulla realizes that Celica is calling for Scar, she allows Scar to adopt her sister. She had some idea about her powers, but she doesn't know the whole truth until Ai tells her.
Deadly Gaze: And it's not just her eyes that can kill the living, but also her voice and very touch.
A mysterious boy Ai meets while at Goran Academy. He believes he and Ai are similar and he asks for her help. However, his definition of "saving the world" seems to be different from hers.His classmates of Class 3-4 in the sealed city of Ostia are trapped in an endless loop that repeats every July 28th, and he wants to destroy that world so he can free them. When he died while saving Dee from falling out a window, his classmates wished to reset time to prevent his death, thus trapping themselves in said time loop. When Alice realizes the truth, the seal begins to break, and he's about to disappear when Ai makes the wish to save him.
Back from the Dead: Played with. The "Alice" who died before the time loop began is still dead (he even says he was buried by a gravekeeper), but before the seal breaks completely Ai wishes for the "Alice" who lived through all those time loops to be able to continue to exist in the outside world. Her wish comes true, much to his surprise.
A ghostly girl Ai meets while at Goran Academy and Alice's companion. She is known as "Whisper" and the "Witch of the West," and she can secretly whisper suggestions and commands to people, compelling them toward certain actions. In fact, she did this once to Ai so that she would head to Goran's clocktower to meet Alice.However, despite her ghostly appearance she isn't actually dead. While in Ostia, she leads Ai to believe that she was the one who died, and her true goal is to destroy the outside world so that Alice will have no choice but to remain in Ostia, since because she loves him, she doesn't want him to disappear.
Blessed with Suck: While being a ghost has its advantages, the bonus episode shows that Dee is sometimes bothered by being unable to physically feel anything.
Bokukko: She uses the masculine "boku" to refer to herself.
