Necronomidol, the ultra-dark idol unit, was founded in mid-2014 as an example of an alt-idol group that is Darker and Edgier even among other alternative idols, as opposed to the usual Idol Singer tropes. Their initial output consisted in a blend of traditional Japanese folk music and aesthetic with Black Metal; later on, they began to incorporate other metal genres and other styles such as Dark Wave and Synthwave, for a catchier sound that still mantains the general somber attitude. Their imagery is influenced by, other than the aforementioned Black Metal's visuals, the occult, Japanese and Western horror tropes and (as their name implies) the Cthulhu Mythos.
Interestingly enough, they were self-produced and the unit's founder and producer Ricky Wilson (not the singer from Kaiser Chiefs) is an American living in Japan, who, as a fan of both idols and horror, wanted to create an idol unit themed around the paranormal: by all accounts, he succeeded. Unusually for a Japanese idol group, they also toured several times in Europe and the US, building a nice following for what is a very niche product.
In late 2018 the management announced that Sari and Hina Yotsuyu will leave the group to pursue other activities, effective from January 2019. Kunogi Kenbishi and Michelle took their place since then. However, Kunogi had to leave the unit in September 2019 (read the Trivia tab for the reason why). They were also scheduled to perform at the 2020 Monster of Dolls Japanese idol music festival in Italy but canceled their participation for unknown behind-the-scenes reason, with the manager citing something about the contract they signed. (Sari was a special guest at the 2019 edition, after leaving the unit).
In early 2020 it was announced on Twitter that every member (Risaki, Rei and Michelle) except Himari would leave the group. No reasons were given for the members' departure; it was said that it was caused by an "incident" behind the scenes, but the reason will probably never be known. The management said that they were in the process of recruiting new members, and the official Twitter revealed them, as well as a date of June 2020 for the unit's "rebirth". They are Nana Kamino, Shiki Rukawa and Toda Roa. In the meantime, Risaki, Rei (now known as Ray), together with their old friend Hina and a fourth girl became part of a new unit named MANACLE, with a vaguely similar aesthetic.
However, history repeated itself in 2021: the unit entered a hiatus since April because of Nana's health issues, Shiki's sudden graduation and Toda's commitment to her parallel solo singer-songwriter career. The management had plans to introduce a fifth member to the group, but at this point the future of Necronomidol is up in the air.

Their dark tropes:
- all lowercase letters: Some examples, like the "from chaos born" album or the song "puella tenebrarum".
- Animated Music Video: Combined with Retraux. Their video for SKULLS IN THE STARS is made to look like a NES-esque game where they are resurrected by some Eldritch Abomination to destroy some even worse creatures and prevent the apocalypse. As a fake video game, it has a slew of other tropes on its own.
- Bare Your Midriff: Risaki's usual attire. And in the music video for "Ritual", Himari sports some impressive abs.
- But Not Too Foreign: Inverted by their manager, who is American and speaks Japanese as a second language after living there for years.
- Dark Magical Girl: Taken quite literally at the end of the music video for "STRANGE AEONS".
- Deliberately Monochrome: Several of their early videos were shot in black & white for maximum bleakness.
- Early Installment Weirdness: As mentioned above, their early singles were much more influenced by Japanese culture, so their stage costumes were inspired by miko attire; they abandoned this later. Also, in their earliest appearances, Sari didn't always have her iconic green bob wig.
- Eerie Pale-Skinned Brunette: Their aesthetic, taken Up to Eleven with Sari's white face paint. Interestingly, her makeup is not a reference to black metal's "corpse paint", since she was a shironuri ("white face") performer well before entering the group.
- All the girls finally wear actual corpse paint in the "Ritual" video.
- Girlish Pigtails: Hina's trademark. New member Roa Toda has them too.
- Gorn: The professional illustrations on their album and singles sleeves were made by some of the most (in)famous masters of ero-guro art, such as Shintaro Kago, Waita Uziga and Toshio Maeda (of Urotsukidoji fame). Some may seem tame, but there are also more nasty variants.
- Gratuitous English: Used sparsely in their lyrics. In an amusing variant, the Animated Music Video mentioned above has the girls speaking Japanese, while the Lovecraftian abomination speaks in (almost) grammatically correct English.
- Halloween Cosplay: This post for Halloween 2017, featuring Risaki as Leatherface, Rei as Chucky, Sari as Sally (also a nice Punny Name!), Hina as Celestia and Himari as a Japanese ghost lady.
- It Is Pronounced "Tro-PAY": Is it Necronom-IDOL or Necronom-EE-dol?
- Lighter and Softer: Sari's output after leaving the group to pursue a solo career, see for example this MV that has a completely different, much more colorful, aesthetic.
- Light Is Not Good: The official pics that show the new lineup for 2020 has all the girls dressed in white. It should be noted however that in Japan white, and not black, is the color associated with death.
- Lyrical Dissonance: For example, psychopomp. It sounds sweet and almost calming, but the lyrics are chilling. Bonus points for the video being shot in the actual "suicide forest", Aokigahara.
- Officially Shortened Title: Necroma.
- Only One Name: Sari is just Sari and always will be. Michelle too, and she also counts as Odd Name Out as her stage name is typically Western as opposed to Japanese.
- Portmantitle: Necronomicon + Idol.
- Seven Is Nana: New member Nana Kamino uses the word "seven" in her social network addresses.
- Theme Naming: Several references to the Cthulhu Mythos, from their very name to songs titled "Abhoth", "Ithaqua" (names of creatures from the mythos), the "Strange Aeons" album and so on.
- You Gotta Have Blue Hair: Sari's green wig, then Kunogi's pink/reddish hue and Michelle's bluish hair.
