In Northern Germany 11 year-old Aya Drevis, lives with her parents, Alfred and Monika Drevis, and their maid Maria.

Neither Aya or Monika are aware of the true extent of Alfred's research, but both accept it out of their love for Alfred. When Aya is 10, Monika suddenly passes away from what Aya believes was her illness.

Taking place one year later on the anniversary of Monika's death, Aya awakens at midnight to find that her home has been inflicted with a curse that her mother imposed, and that the victims of Alfred's experiments have come to life due to this curse. Aya sets out to rescue her father, who had taken captive by Monika, with the assistance of a mysterious salesman Ogre. She must explore the depths of Alfred's laboratory, a man of which who may not be exactly what he seems.


Aya Drevis[]

The preteen daughter of Monika and Alfred Drevis. She's very devoted to her parents, even though she's aware of her father's actions. However, this means she has a lack of empathy to anyone that isn't herself of her parents. After her experiences in the story, she'll learn to understand the pain and feelings of other people, like her father's victims or Maria.

Alfred Drevis[]

Aya's father, a brilliant but unhinged scientist. Ever since he was a boy, he was obsessed with eternal beauty, and sought a way to make beauty last forever, even after death. His solution was to turn people into living dolls. He gets kidnapped by the spirit of his wife, forcing Aya to save him.


Alfred's assistant. She used to be homeless orphan and Alfred was originally going to experiment on her, but he changed his mind when she proved herself to have high medical skills. Just like Aya, she is devoted to Alfred and is willing to do whatever he says. Neither Monika nor Aya liked her because of her affair with Alfred, though Aya learns to care and sympathize with her after finding out about her past and why she's so devoted to Alfred.

Monika Drevis[]

A beautiful, enigmatic woman who died prior to the start of the game, only to return as a spirit and capture her husband. Aya seems to rescue Alfred from her. The player can choose whether or not to grant her wish to kill her husband or to save Alfred and lose Monika.


A mysterious man whom informs Aya about the curse. It's never stated who or what he is, but it's implied that he is a demon. He is the one who helped Monika place the curse.


A seemingly undead boy that Aya encounters in the mansion. He occasionally shows up to help Aya. The 2020 Nintendo Remake reveals he was an orphan taken by Alfred so he could be experimented on. He interacted with Aya a few times, but she doesn't remember him at all, until he sees his memories. It's also revealed he was killed by Alfred, but Monika brought him back to life so he could protect Aya.

She states that she will continue doing the doctor's experiments, starting with Aya herself.

Bad Ending 2[]

If Aya chooses to save Alfred, but doesn't help Maria, he will succeed in killing her. He will have her propped up on a chair in the doll room, wearing a nice dress.

True Ending[]

Dio ending.png

If Aya chooses to save Alfred, Monika will disappear. Aya and her father will be returned to the lab where Monika's ghost shows Aya how she died. Apparently Alfred was worried by how Aya had the same murdering tendencies as him, so he decided to kill her and make her into a doll in order to keep her pure forever. Monika confronted him about this and decided to take Aya away, but Alfred killed her. Shocked by the revelation, Aya will start crawling away from her father and hit a container, holding her mother's corpse. No longer feeling the need to feign ignorance, Aya's father reveals to her what he had been doing all this time: turning humans into dolls via taxadermy and plans to do the same to Aya. Alfred proceeds to chase Aya with a chainsaw. They will stumble upon Maria who joins Alfred in the chase. Aya will hide under a tarp and Alfred, out of frustration, will strike Maria down and storm off. If the player chooses to save Maria, she will temporarily join Aya until they reach a long hallway.

Aya will run off without her and, just as she's running away, will be held down by another doll. Aya's father will prepare to strike Aya when Maria shows up and throws knives at him, Just as Maria is comforting Aya, the doctor will try once more to kill Aya, but Robin will kill him and order Maria and Aya to leave the mansion and start anew. As the mansion is set on fire, he places a kiss on Aya's forehead in reference to the good luck charm her mother gave her. Ogre will then approach Alfred's corpse and take him to his realm. Just as Aya prepares to leave with Maria, she finds a mysterious book, which she takes with her.

Years later, Aya opens up a clinic, which examines patients for free. While she is working on a young woman named Jean, Maria states that Aya has become just like her father. The 2020 Nintendo Remake reveals that Aya indeed kills people, but unlike her father, she treats them like people instead of as mere "parts", and her victims are anesthetized before she kills them, relieving them of the suffering her father would've inflicted on them.

Secret Ending[]

This ending can be accessed if the player collects all of the gems in the game. It reveals Ogre took Alfred to live with him at his realm. Alfred continues to do his experiments and has made a clone of Aya.

"If" Scenario[]

This route was added in the 2016 Steam Remake. After Robin kills Alfred, Maria will take Aya to her room so she would rest. Maria tells Robin that he doesn't seem to be a corpse like the other monsters, but he insist he is one and tells Maria to protect Aya. Meanwhile Aya talks in her sleep, wanting to live with Maria from now on, as they're alone.

Robin wanders around the mansion and talks to the corpse in the bathroom. It's revealed the corpse is actually a butler who served the Drevis family and was killed by Monika when he found out about Alfred's experiments. He condemns her as a wretched and manipulative woman, but Robin says that even if Monika wasn't a good person in the end, that doesn't make her love for Aya any less real. Robin also confronts Ogre, who confirms he helped Aya because he was interested in Alfred and his psychopatic attitude.

Later Robin sets the house on fire and says goodbye to Aya and Maria, just like in the True Ending. As he walks away, he encounters the doll Aya had in her room, who warns him that Aya might follow in her father's footsteps in the future. He vows to stop her if that ever happens.

"Blood Mode" Scenario[]

This route was added in the 2020 Nintendo Remake. Years later, an adult Aya receives an apple from a hooded woman. She bites it and falls into a deep sleep. Afterwards, Aya relives the events of the mansion, encountering the corpses of the patients and Ogre, who greets her as an old friend.

She also finds about her mother's past and how she isn't as innocent as she thought when she was young. Turns out Monika's family was into medical experimentation and torture to the point that it was seen as a family business. Her aunt was killed for trying to go against it, and Monika shamed her for being vocal about it before her death. She also wished to live by the wishes of her grandparents, as while her grandfather wants her to continue the traditions, the grandmother wishes for them to stop and she feels conflicted on who to follow until she comes across Alfred and gets an out by letting him do the deeds. It's also revealed she never truly loved Alfred or Aya at all, and the only reason she wanted to save her from becoming a doll was so she could continue the traditions of the family.

In the end, Alfred encounters Aya once again and tries to kill her. Aya accepts it, wanting to be reunited with her parents in the afterlife. However, she remembers she still has Maria waiting for her, so she confronts him. Aya hugs him and says that while she understands his motivations now, she'll continue killing people and he has to accept it. Alfred wishes her happiness and disappears. At that moment, Aya wakes up from the dream. Maria wants to get revenge on the woman who gave her the apple, but Aya tells her to forget about the incident.
