Date of Birth: November 17, 2004 Charm Point: "Cat Eyes." She has long, striking eyes and is the best at expressing the "cold gaze" or "glare" unique to horror. White Representative: "Ethereal Beauty." The contrast of black hair, pale skin, and red lips creates an eerie beauty reminiscent of beautiful Japanese ghosts or dolls. Performance: A "possession-type" performer who explodes with emotion. As she says herself, "I love letting my emotions explode," her intensity on stage makes it feel as if she is possessed by obsession or a grudge. Clear Voice with Core: Based on a calm tone befitting the eldest member, she freely switches between maturity and madness depending on the song. Character: The "gap in her true self" that makes her impossible not to love. A huge foodie: Contrary to her cool appearance, she loves the act of eating itself—ice cream, cheese, bagels, sashimi, etc. She's such a foodie that she even posted a binge-eating video on her birthday. Delicate and Pure Interior: Though seen as a bright older sister figure by those around her, she actually has a side that is "negative, a crybaby, and indecisive." She is a serious and pure-hearted person who gains power by watching movie protagonists work hard. Dialogue Image: "I'm Miu. People usually say I'm fairly calm, but I'm happiest when I'm eating something delicious. On stage, I want to deliver expressions that will take everyone's breath away." Speech Style: Calm and composed.

Pink Representative Date of Birth: September 17, 2007 Visuals: Adorable like a white rice cake, with "classic idol bangs" like a doll. Features/Voice: The one who leads the group's "cuteness," characterized by a charming and sweet singing voice. However, she has a "gap" where she can strike with heavy low-register parts depending on the song, captivating fans with her wide range of expression. She loves researching makeup and collecting cosmetics. Dialogue Image: "I'm Mona from Phantom Siita! I just love being cute, and my hobby is collecting makeup and cosmetics. I want to be an idol who sings, dances, and talks a lot with everyone!" Speech Style: Bright and cheerful.

Purple Representative Date of Birth: May 9, 2007 Visuals: Long, narrow eyes that exude sensuality (snake/cat-like), and a straight black ponytail that reaches her waist. Features/Voice: Despite her young age, once she stands on stage, she radiates a mysterious and cold beauty. Her long black hair moves beautifully with her dance, making her a member who strongly visualizes the eerie yet aesthetic world of retro horror. Dialogue Image: "I'm Rinka. I put more heart than ever into the recording of our new song. I would be happy if you could fully immerse yourself in our world." Speech Style: Gentle and at her own pace.

Light Blue Representative Date of Birth: October 20, 2006 Visuals: Heavy, straight-cut long hair reminiscent of a Japanese doll. Features/Voice: Possesses a powerful singing voice that is already complete in her teens, with a unique resonance that feels Japanese in essence. She is often entrusted with the opening lines of songs, drawing listeners into the world instantly. However, she is actually the "biggest coward in the group," fearing not only horror but even pigeons because "you can't tell what they're thinking," showing a very cute true self. Dialogue Image: "Everyone, thank you so much for today. I will never forget this day as long as I live. I hope you continue to support our activities!" Speech Style: Reliable yet bright.

Green Representative Date of Birth: May 1, 2003 Her trademark was neatly trimmed straight bangs and a hairstyle with the sides tied or pulled back. The gap between her cool, somewhat shadowed beauty and the lovely smile she shows in unexpected moments is extremely attractive. Overflowing "Heavy Member Love": Despite being the oldest in the group, she is famous for her affection for the members being extremely strong and "heavy." She often sends long, love-filled messages to the members. In making-of footage, she even left a famous (?) quote: "I want to put the members in my eyes instead of colored contacts," pouring out her own unique, deep love. She deeply respects the producer, Ado.
