The protagonist of the first Fatal Frame who goes into the Himuro Mansion in order to look for her brother, Mafuyu. She finds the Camera Obscura where her brother left it, and then she must collect five pieces of a holy mirror in order to stop the ghost of Kirie gone berserker.She returns in Fatal Frame III, again as a playable character and still lamenting the death of her brother, Mafuyu. Such guilt haunts her dreams, and so she finds herself trapped in the Manor of Sleep, where she can't help but to follow the ghost of her loved one.
Crippling Overspecialization: A mild example in FF3. Her Sacred Stone (which slows ghosts) and 'Double' function (stacking a charge on top of a full one) special abilities are extremely useful, but in exchange she doesn't have any special lenses.
Miku and Mafuyu's great-grandmother. She lived in the Himuro mansion decades before the events of the game take place. She commits suicide due to her daughter's disappearance combined with overexposure from the Camera Obscura.She is reintroduced in Fatal Frame II, where she is revealed to have had a twin sister, and was the unwitting instigator of several events in the game.
The protagonist of Fatal Frame II and Mayu's younger twin. She has a weaker sixth sense, so she isn't as perceptive about the ghosts as Mayu, but this also makes her more resistant to their influence. Mio is very protective about her sister, feeling responsible for her leg wound years ago, and so she looks after her every single day.Mio comes back in Fatal Frame III, but not as a playable character. Still lamenting Mayu's death, she is afflicted by the Tattooed Curse, and her uncle Kei is trying to rescue her.
Baleful Polymorph: In the Deeper Crimson butterfly's Frozen Butterfly Ending, the crimson butterfly can be interpeted to be Mio after Mayu strangled her.
Think Nothing of It: Her attitude towards Mayu, which seems to extent even after she loses her sight for her.
Together in Death: With Mayu in Deep Crimson Butterfly, if you got the "Shadow Festival" ending.
Trauma Conga Line: Type C. First, she's left feeling guilty for Mayu's childhood injury, then spirited away to a nightmarish village where she's forced to kill her sister to leave, then she's forced to revisit the trauma all over again in her dreams.
Mio's older, calm, reserved and considerate twin. She's got a very strong sixth sense, which makes her vulnerable to the influence of ghosts. This leads to get being possessed by Sae, causing quite a troublesome situation as the person Mio has to rescue is at the same time the person who could mean her immediate death.
Identical Twin ID Tag: Her hairstyle is layered close to her head, and her fringe is straight and covers more of her forehead. Her clothing also gives a more demure feel, compared to Mio's.
If I Can't Have You: In Deep Crimson Butterfly, she actually murders Mio when the latter refuses to perform the ritual in one ending.
The Load: That said, she makes for an excellent distraction for attacking ghosts.
Laughing Mad: In Deep Crimson Butterfly's Frozen Butterfly ending. She must've been taking lessons from Sae.
Manipulative Bitch: In the Japanese Fanbook (As well as the novelization), it is revealed that when they were children, Mayu fell down the cliff on purpose so Mio wouldn't leave her behind, and has been using her injury to control Mio ever since. During the final battle against Sae, Mayu can be heard saying "Mio always thinks about me... and she will do whatever I say."
Meaningful Name: Mayu means "cocoon" tying in with the butterfly theme. She does indeed become one in the default ending.
A white-haired young boy that is mysteriously imprisoned. Mio encounters him while exploring the lost village, and he'll assist Mio in his attempt to rescue Mayu, although most of what he says will cause confusion to the player.
Angsty Surviving Twin: His failure to properly perform the ritual meant that his brother, Mutsuki, died for nothing. He killed himself to join his brother after he thought the Kurosawa Twins escaped.
A twin shrine maiden who particularly had been always anxious about participating in the sacrificial ritual so she would become one with her twin sister, Yae. When Itsuki wanted to help Sae and Yae to escape the ritual, though, she apparently intentionally fell behind, hoping that Yae would return for her so they would fulfill the ritual. But Yae never came back, and so she was sentenced to do the ritual alone, which didn't go well.
All Love Is Unrequited: She was close to Itsuki, but because he's the older "Remaining" twin and she is the younger twin that will be sacrificed, they can't be together.
Dangerously Genre Savvy: Generates a red mist to protect against the Camera Obscura during the final battle with her, and come on, how many ghosts are smart enough to realize that the only weapon in the protagonist's arsenal is the Camera Obscura?
Death Glare: It's a blink-and-you'll-miss moment, but in the remake of the Lingering Scent ending, the look on her face as she strangles Mio is... quite unsettling.
Light Is Not Good: The most vibrant colored out of the four main antagonists and the most psychotic.
Manipulative Bitch: Like Mayu, she fell on purpose to try and get her sister caught in order to force her into the ritual, without any consideration for her sister's feelings. Unlike Mayu, her plan backfired horribly.
A professional photographer and protagonist of Fatal Frame III. She lived together with Miku and her boyfriend, Yuu, until he died in a car accident caused by her. Because of this, she gets dragged into the Manor of Sleep, following his ghost.
Dangerously Genre Savvy: With Kei's help and the Handmaiden's Song, she figures out how to truly end the curse: sail the quelled "tattoos" (Reika) and "their offering of tears" (Kaname) to the other side of the Abyss.
Death Seeker: It's strongly hinted by the end of the game she became this, completely willing to be spirited away in order to be with Yuu.
Informed Attribute: Rei claims she's the opposite of Yuu who was quiet and gentle, but this doesn't really show. Then again, she is severely depressed.
It's All My Fault: It is. It was her irresponsible driving what got her boyfriend killed, after all.
Please Don't Leave Me: When Yuu's spirit is crossing the Rift with other spirits, she begs to take her with him. He declines, telling her that he'll live on through her.
Psychic Link: With Miku and Kei, allowing her to see their dreams of the manor within her own. However, as seen with what happens to the two, she has no influence on their decisions.
Mio's uncle, a non-fiction writer. He was also good friends with Yuu, and writes letter to him during the game which Rei receives. These help her unravel the mystery of the Manor of Sleep. The main reason he is investigating the manor is to save his niece Mio, who fell victim to the Tattoo Curse.
Badass Bookworm: Comes with being one of the series' folklorists who can actually fight off ghosts and not end up one of them. Even then, up until you play his chapters he had no Camera Obscura and had to hide often, hence his ability and special filament. Regardless of how weak his sixth sense is, the man's certainly something to have been sneaking around a haunted manor for so long (the extent of his tattoos show that he's been in the manor the longest out of the three).
Can't Catch Up: In a somewhat different way than most examples. Being the only playable man in Fatal Frame III, he's stronger than the girls and so he can move heavy objects they can't. But his sixth sense is said to be weaker than theirs, which results in his attacks being overall inferior, and that's when he has a camera to begin with.
Gradual Grinder: His Camera Obscura though is best used to chip away at a spirit's health with rapid combos and bonuses, as he can't charge it to levels as high as Rei or Miku.
Mr. Exposition: Subverted. His chapters are where you usually find the documents that explain the Kuze Family and their rituals, that which lead up to the existence of the Tattoo Curse and the Manor of Sleep.
Meaningful Name: The character for his name means 'firefly', referring to the light of hope he has for finding a way to end the curse. However, fireflies are also known for their brief lifespans.
The tattooed priestess, and possibly the biggest Woobie, Destroyer of Worlds in the series. Like Kirie, she was a Virgin Sacrifice for a ritual that, because of a secret romance and a string of tragic events, lead to her unleashing the Rift and spread her suffering to others through their dreams.
Break the Cutie: The final straw was Kaname being murdered right in front of her.
Trauma Conga Line: Dear lord! In order: She lost her family and village to an avalanche, adopted by another family and forced to endure Cold-Blooded Torture until she died during which she finally found love, only to have that love brutally murdered in front of her. Would someone give this girl a hug?!
The 17-year-old, soft-spoken protagonist of Fatal Frame IV. She was the last victim of the kidnapping incident and can't remember much about her time on Rougetsu Island. When she hears about the mysterious deaths of the other victims, she decides to return to the island.
Meaningful Name: Her name can be read as "the flow of a song". The Tsukimori Song plays a very important role in the story.
Miko: The true Kiraigou considers her one, as a Tsukimori Shrine Maiden is required to fully complete the ritual and play the Lunar Melody. The practice died out, but Ruka's mother Sayaka took her bloodline as one seriously, teaching her daughter the song.
Parental Abandonment: Sayaka died of illness some time before Ruka left for Rougetsu Island, and her father Souya was presumably killed during Sakuya's rampage.
A strong-willed girl who was kidnapped on Rougetsu Island as a child. Hearing that the other victims are dying mysteriously, she takes Madoka to their childhood place to recover her memories. She's a descendent of the Camera Obscura's inventor, Kunihiko Asou. She inherited a strong sixth sense that leads to her spiritual connection with Sakuya.
A reserved girl who was one of the kidnapped victims. After the deaths of her friends, Marie and Tomoe, she was dragged along by Misaki to Rougetsu Island to uncover the truth. She ends up spirited away and reappears as a boss for Ruka and Misaki to fight.
The Legend of Chekhov: A letter from her mother tells her that their family bloodline will protect her. It doesn't, but the Tsukimori name becomes much more important later in the story.
Ex-police officer turned detective. He discovered the five abducted girls in a cave beneath Haibara Hospital and has been chasing the perpetrator, You Haibara, ever since. Unlike other playable characters, he uses a device called the Spirit Stone Flashlight to fight ghosts.
Determinator: It causes him to be caught in a cycle of pursuing You Haibara until the moment of his death. On a more positive note, it also saves him from the Getsuyuu outbreak. His determination in finding Haibara snaps him out of his fear of Sakuya's distorted face (he caught a glimpse of You running away during so), which would have caused him to Bloom otherwise.
Lunacy: How the Spirit Stone Flashlight exorcises ghosts: it shines absorbed moonlight from the Spirit Stones to purify their spirits.
Resurrected for a Job: Played with. The spirit of Sayaka contacts him to aid Ruka when she returns to the island. He's still dead, but it breaks the loop his spirit was trapped in, and later he can join the others to the afterlife.
The antagonist of Fatal Frame IV. Her father and brother tried to cure her disease by making her dance in an ancient ritual. The ceremony failed so she now wanders the island inflicting death on all who look at her.
Came Back Wrong: The ritual did not kill her; only leaving her a state between life and death. However, that allowed her to Bloom, a normally postmortem and contagious symptom of Getsuyuu Syndrome.
Cool Big Sis: She was this to her brother You, and also fellow patients Misaki and Ayako.
The Faceless: The nurses often mention that they can't remember her face even after seeing her, which horrified them.
Many Spirits Inside of One: As the Utsuwa of the Kiraigou, her true purpose is meant to be the vessel in which ghosts are sent through to enter the Afterlife.
Meaningful Name: The characters of her name are read as "night of the new moon." Saku is also synonymous with the verb "to bloom".
Sanity Slippage: Came with the later stages of Getsuyuu Syndrome, combined with an immensely powerful sixth sense. The reason why she isn't even referred to by her name early on is that the realization of severe lapses in her own identity caused her to have violent fits.
Unkempt Beauty: When her face is visible, she's considered to be one of the prettiest characters in the series.
