Mieruko-Chan: The Girl That Sees "Them" is a Horror Comedy by Izumi Tomoki, originally published on Pixiv.
Miko is a completely ordinary Japanese high school girl. She goes to school, hangs out with her best friend Hana, and tries not to attract the attention of various horrifying ghosts and spirits that seem to haunt her hometown, creatures that no one else she knows can see.
- Accidental Hero: In chapter 14, Julia sees Miko's clumsy attempts to keep some ghosts away and thinks she's doing it deliberately, to show off.
- A-Cup Angst: There's a few jokes about Miko being jealous of her bustier friend Hana.
- A Day in the Limelight: Chapter 10 focuses on Hana, who unwittingly goes into a haunted building to look for a lost dog.
- Bait-and-Switch: Chapter 9 has Miko go downstairs and see a troll-like ghost haunting her family, who are eating breakfast totally unaware. Miko looks and acts incredibly uncomfortable the entire time, seemingly because there is such a horrifying ghost around her parents. The end of the chapter reveals it's because her father is also a ghost who died a year before and seeing him upset her.
- Creepy Good: The "gods" that banish the monster haunting Hana in chapter 11 appear benevolent, but are just as terrifying as the other creatures Miko sees. They also offer Miko a cryptic warning: "Three times."
- Dark Is Not Evil: For all that the ghosts are horrifying, some of them are fairly harmless.
- Face of a Thug: In chapter 4, Miko convinces Hana to give a stray kitten to Gozuka, a thuggish-looking fellow covered in tattoos. He's surrounded by ghostly cats (which are actually based on nekomata) that are much more benevolent than the spirits Miko normally sees, and he does turn out to be a Kind Hearted Cat Lover.
- Framed for Heroism: In chapter 14, the spirits from the shrine in chapter 11 show up to save Miko and her friends from a particularly horrifying ghost, but Julia seems to assume that Miko was the one who saved everyone.
- Hospital Hottie: Miss Kido, the nurse at Miko's school, proves to be a more tempting target than Hana for a perverted ghost in chapter 3. Unfortunately for the ghost, who gets exorcised by her powerful flower-scented perfume.
- I See Dead People: Miko inexplicably gains the powers to see strange ghosts and monsters wherever she goes.
- I See Them, Too: Chapter 12 introduces Julia, a young girl who can also see ghosts and spirits, though not as well as Miko. She declares Miko her rival after learning she (unwittingly) drove her mentor, the "Godmother of Downtown", to quit the fortune-telling business.
- Kitsune: The "god" from chapter 11 that devours the spirit haunting Hana vaguely resembles a fox with multiple tails.
- Madness Mantra: In chapter 13 Miko encounters a ghost muttering the words "Four... six... three... one..." over and over. It turns out to be the ghost of an old woman's husband, trying to remind her of the combination to his old safe.
- Magnetic Medium: Central to the plot. Once Miko started seeing spirits, she's only started seeing more and more as time goes on.
- Masquerade: Miko does her best to keep her ability to see spirits a secret.
- Nonverbal Miscommunication: In chapter 14, Miko winks at Julia to indicate they should give up trying to get through the haunted tunnel. Julia thinks that Miko wants her to show what she can do.
- Not-So-Phony Psychic: In chapter 6, Miko goes to Mitsue Takeda, the "Godmother of Downtown" for help with her ghost problem. Mitsue seems like an old fraud who's just looking to make money, but she does have enough genuine psychic ability to see the presence haunting Miko.
- Not What It Looks Like: In chapter 7, Miko's younger brother Kyousuke becomes convinced that his sister's weird behavior is because she has a boyfriend.
- Our Ghosts Are Different: The creatures Miko encounters come in all shapes and sizes, some of them almost human and others horribly twisted parodies of humanity.
- Parting Words Regret: Chapter 9 implies shortly before the death of Miko's father, she had an argument with him over eating a seasonal chestnut pudding cup she'd bought for herself.
- Refusal of the Call: Rather than try and reach out to the creatures and ghosts she sees, Miko does her level best to ignore them and get on with her everyday life.
- Screw This, I'm Outta Here!: When the "Godmother of Downtown" learns her strongest wards and spells are no match for the latest presence haunting Miko, she calls it quits on being a fortune teller and goes back to the country to live with her son.
- Twist Ending: Chapter 9 ends with the reveal that Miko's father is a ghost, too.
- Weirdness Magnet: An unwitting one. Hana has such an intense aura that enormous quantities of spirits are attracted to her, but she can't see the chaos that occurs in the spirit world as a result.
