-Just Wanna XXXXX with You
Take classic Japanese horror works like Tomie, Ju-on, The Ring, Audition, Suicide Club, et cetera. Sprinkle in City Pop, especially the infamous Jun Togawa. And finally, add a healthy serving of Idol Singer music.
Voila — you've got Phantom Siita, an idol group formed by Ado and backing from Kikuo. Four, formerly five, yanderes cheerily singing about death, the fine line between love and murderous hatred, ghosts, monsters, murder plots, serial killers, and especially murdering you. Y'know, just like any other idol group!
The members consist of Miu, Mona, Moka, Rinka and Hisui. The group debuted in June 26, 2024, with the song "OTOMODACHI" under Cloud Nine inc (Ado's agency).
On May 17th, it was announced that Hisui would leave the group due to health reasons at the end of May, but was able to record and perform for one more song, "Doppleganger" (Released in July 9, 2025), before her departure.

All I wanna do is trope, trope, trope, trope, trope...
- Alice Allusion: "Noah" is visually inspired from Alice in Wonderland, with the members acting as "Alice".
- Animal Motifs: Siita means moth, and represents death — as in, like moths to a flame, burning brightly as they die, which fits their motifs of standing out from the idol industry in a brief burst of flame, and dying in the process. The group's concept is to serve as the anti-thesis of many idol groups as the "moths" to their "butterflies". Additionally, moths are also known to mimic after swallowtail butterflies, reflecting the antithesis further.
- Ax-Crazy:
- "Just Wanna XXXX With You" is one long insane death threat from yanderes about how they're going to brutally murder you for making them fall in love with you.
- Their cover of Jun Togawa's "Suki Suki Daisuki". The original song was from the point of view of a woman who can't express how deeply in love she is and has to use metaphors of violence to get her devotion across. The cover plays it far more straight.
- Color Motifs: Each member has one.Miu: White
Mona: Pink
Rinka: Purple
Moka: Light Blue
Hisui (Now former member): Green - Destructive Romance: The girls of "OTOMODACHI", whose love devolves into accusations of being unfaithful or secretly spreading rumours about each other. It's heavily implied to end in a Murder-Suicide.
- Evil Laugh: During live performances, at least one of the girls will break out into unhinged laughter during any song.
- Genre Mashup: The band mixes up J-Horror films, sukeban exploitation series like Sukeban Deka, City Pop, and Idol Singer music.
- Genre Throwback: The band pays homage to several genres:
- "J-Horror" cult classics like Ju-on, Kwaidan, Curo, Audition, The Ring, Suicide Club, etc.
- Sukeban television series of high-school delinquent girls kicking ass, like Sukeban Deka.
- City Pop, including weirder acts like Jun Togawa. In live concerts, the band covers classic J-pop songs like ''Fly-Day Chinatown", "Natsu Matsuri" and "Can't Stop the Loneliness".
- I Just Want to Be You: The motive of the Doppelgänger taking over the young girl's life in "Doppelganger".
- Pun: "Just Wanna XXXXX With You" has several:
- The chorus, depending on how you hear it, is meant to be either "kill you" or "kiss you". Additionally, "chuu" makes up part of the word "chuu suru", which is to punish and execute a criminal.
- "Gero" is the sound of vomiting (in this case, presumably from the injuries the girls are inflicting on their love interest), but it's also the sound of a frog or toad croaking, which is referred to in the next line by making fun of the unfortunate "lover" by comparing him to a toad.
- Kill and Replace: The MV and lyrics for "Doppelganger" is about a young girl having her life replaced by her Doppelgänger and then realizing that the people around her are also Doppelgänger's too.
- Meta Twist: "Hanagatami" is the one song of the group that had been released as of writing to not follow or be inspired from a horror theme in its music and lyrics, being a ballad of self-introspection of the singer accepting their flaws and seeing the beauty in them as part of their identity.
- Psychotic Love Triangle: "OTOMODACHI" is a Love Dodecahedron of backstabbing psycho girls madly in love with each other but who can't help but do awful things to each other out of insane jealousy.
- Serial Killer: Zoku Zoku is about apparent prostitutes who instead prey on unsuspecting "clients".
- The Vamp: "Zoku Zoku" focuses on oiran (elite courtesans) seducing their clients so they can murder them.
- Woman of a Thousand Voices: A given due to being produced by Ado, who is one herself. Most of the songs had the girls switch between singing to screaming and/or evil laughing depending on the song. An interview reveals that members auditioning for the group must sing Ado's "Tot Musica
", a vocal intensive song by itself, during the audition, of which the members showcased their talent to nail said song in one of their live concerts
. - Woman Scorned: An alternate interpretation of the lyrics of "Just Wanna XXXXX With You" can be seen as the girls who loved a boy at the same time who were being murderously angry at him for toying all their hearts and want him dead while still loving him at the same time.
- Yandere: A reoccurring theme is insane, unhinged love, connecting to its horror inspired visuals and concept, not only in their original songs, but also in covers in their Live Tours where the members came up with their own original choreography for the songs they are covering.
- It's best exemplified in "Just Wanna xxxx With You
" (sic), where all five girls are murderously obsessed with their crush, blaming him for driving them to insanity and torturing him to death. The title refers to the chorus: the chorus makes the Japanese words for the sound of kissing segue into wanting to see their crush's blood, eventually devolving into execution, execution, EXECUTION!!! The music video takes it further by drawing on old J Horror and anime tropes, including Onryo (vengeful Japanese ghosts, usually abused women) and Takashi Miike's Audition. The dance routines include Slasher Smiles and movements invoking decapitation. - "Devilish Girl" shows the other type of yandere: apparently sane and reserved, only to reveal she's got her crush cornered and is threatening her crush's actual love interest:
Your only escape is me
Attraction pulls us together
There's no place for you in the afterlife
So be it, there's no help for it
Let's be drawn until we decay, devilish
I'm your only place to be
There's no love for you in her
So be it, there's no help for it
Let's make a vow
And let it reveal
Hey, your only escape is me- "OTOMODACHI" shows a toxic relationship between lesbians and equally psychotic Alpha Bitches at a typical-for-the-yuri-genre academy, who eventually accuse each other of being unfaithful. The music video is implied to end in a Murder-Suicide.
Somebody lies, was that you?
You said you wouldn't betray me, didn't you?
Somebody lies, was that you?
Stop hiding, I can tell
You're lying, claiming, "I don't know"
Flip the script, it's all part of the show
Calling cute with a touch of spite
Bash in the comments, ain't no light
Fake friends, they talk the talk
"Secrets for life", but not anymore
Even if you deleted the history
I'll screenshot and post it- Their cover of Jun Togawa's "Suki Suki Daisuki" amps up the already psychotically dramatically-in-love lyrics even more, the choreography for this cover in their live adds up to it
with unhinged laughter and violent gestures. - "Suki, Kirai" mashes up elements of all their songs to be about a psychotically murderous woman killing her lover for breaking her heart, out of the belief murdering him would mean they could be Together in Death for all time.
Love, hate, love, hate
Is that "like" or "love"?
Love, hate, love, hate
If I were to
Ah, end your life
[...]
It would be the beginning of eternity
It hurts, doesn’t it?
Your tears keep flowing
The more you cry, the more it means you loved
It's painful, isn't it?
Your blood overflowing
It flows in me too- Miu's solo cover of Loveit?
, a song about the Destructive Romance between two cannibals for the 2025 Japan tour "Flame Medusa
" has Miu ad-lib in insane laughter and screaming, along with an original choreography for said song that amps up the "destructive" element of the love story between the couple.
- It's best exemplified in "Just Wanna xxxx With You
