Oh girl you don't know what you're just stepped onto. Phantom Siita is just...another new level. Yes, Imma glaze them to the max. So these girl are CRAZZYY TALENTED!! They were selected from 4,000 applicants and made their debut with a pretty unique concept. In addition to their unique concept, they’re also such a POWERHOUSE VOCALISTS. Man, these girls can really BELT while dancing intensely without showing any signs of running out of stamina. And yeah, you’ll also notice that their acting skills are top-notch. Their songs really DO require solid acting skills so that their retro horror concept comes across well to the audience. Just watch one of their live performance videos and I guarantee you’ll be hooked. As for this music video itself, it’s a sequel to their previous one, “Meguru,” featuring the same school setting and vibe, but of course, Phantom Siita can’t stay away from their horror concept for too long, lol. Now, about the members. Since this is your first time watching them, and I’m sure you don’t know who’s who yet, you can actually tell them apart using their assigned color codes. Each Phantom Siita member has a different color: Rinka is purple💜, Miu is white🤍, Moka is light blue🩵, and Mona is pink🩷. These colors are also featured in the costumes they wear, so it’s actually easier to recognize them. There are no official positions in the group, but Haine (Phantom Siita’s fandom) considers Moka (light blue, Hime cut) to be the strongest vocalist and dancer (she’s a K-pop fan). Moving on to their discography, so far, they’ve released 16 songs (including B-sides) and have already gone on one world tour!! Man, you’ll never be disappointed. In my opinion, their music videos don’t do justice to just how talented they are, so please go watch one of their live performances—you’ll decide for yourself whether it’s good or not (I’m pretty sure you’ll love it).

YESSSS I MADE IT YOOOOO IM SO HAPPY IVE NEVER BEEN SO GEEKED IN MY LIFE TYSM PLS REACT TO MORE SONGS

I am Japanese.
Their producer, Ado, is a 23-year-old artist with an incredible singing voice.
Since Ado has fans all over the world, Phantom Siita’s fanbase has also become global.
Consequently, most of their music videos feature English subtitles, though it appears that option wasn't applied in this instance.
In this particular video, they appear as high school girls, but the fact that the themes vary from one work to the next is one of their highlights.
To date, they have portrayed a wide range of characters—including café staff, elves, queens from other worlds, Japanese women in traditional kimono from the past, and Alice in Wonderland.
Yet, every single one of them has a horror theme.
The "Meguru" mentioned in the comment you read is a music video posted on April Fool's Day and is the only one that does not contain any horror elements.

6:10 THERE IT IS. You have now idea how hard I was smiling at the beginning knowing what was coming

2:33 oh you poor soul 😭😭

The best part is that this is probably their least horror filled song (other than meguru)

watching people react to phantom siita is always so fun 🥹🥹🥹🥹

Their Groups theme is actually Retro Horror, they debuted in June 26, 2024 and they were as you said originally a 5 member group, but their fifth member Hisui💚 left due to health issues (Adjustment disorder) she is currently a solo artist. The four are Mona, Moka, Rinka, Miu

For you to recognize them, Mona💓 here is the girl with two ponytails, the girl who killed her friends. Moka💙 is the girl that you keep seeing making creepy expression “Why she did that with her eyes” at the start haha, Miu🤍 is the girl who got stabbed first, Rinka💜 is the one with a bun and has a jacket tied on her waist (?)

This is the only mv with so much blood as far as I remember, so dw you're safe Hahaha!!

Once again, YouTube has recommended another Phantom Siita reaction video to me 🤩
Hey, I’m really happy that someone is doing another reaction to Phantom Siita.
As usual, they mix cuteness and horror really well, and I love it😍
I’m looking forward to your reaction to other Phantom Siita songs 💖

It's always fun to see other people react to Phantom Siita for the first time

This group is an absolute RABBIT HOLE

Pls keep reacting to the girls!
They're REALLY underated just bc they're retro horror!
Maye you'll like Horror Queen, Bot Bakka or if you want a five member song, I love Devilish Girl!
❤

I was waiting for her to change her mind when she said "This is ADOrable", cuz we know Mona killed a man and her girls at the end.

This was such a fun watch! I love Siita, so it’s always nice to watch people react to them ( especially black folks!) I glad you shouted enjoyed and I hope you keep listening!

Recs:

Otomodachi - Phantom Siita
Drop - Hana
Harenchi - Chanmina
Valenti - Boa
Drama Queen  - Lana

oh yeah - they DID kill each other for him, she just killed him in the end because he liked all of them at once im pretty sure and it's based of DDLC 🥰🥰 !! hope that clears up the lore :)

"Ohhh ist so cuteeee" umm yeah about that..

All of the subtle hints that its gonna go horribly for the characters in the MV went straight over her head 😂
Yes they are cute kawaii AF and thats what adds to the “retro horror” (not horror gothic) of the group, the contrast between the cuteness and the straight up horror you see is meant to confuse you and trigger your fight or flight response, japan is really good at that aspect of horror in general and phantom siita has mastered that in their signature style

Pleaseeeee listen to Suki, Kirai by them. Specifically any live performance. Be prepared to be spooked by that song, especially with one of the members, Miu, because every time they perform the song there’s a part where she does a horror laugh and every time she does it differently and it’s genuinely terrifying.

phantom siita is so good! Great producers behind them! def worth checking out all their stuff!

I have seen them live! I’m a big Ado fan and she formed this group.

But now we need a Atarashii Gakko reaction. They are the school uniform group you mentioned at the start. They are really something.
