Hijiri / Vo & Gt [The Fragile Charismatic Leader] The absolute center of mikoto, possessing a voice that silences tens of thousands. However, once away from the microphone, he carries a precariousness that makes him look like he might disappear. Role: Vocals, Guitar Age: 26 Height: 176cm Appearance: Hauntingly thin. Jet-black hair covering his eyes, translucent pale skin. Always wears oversized black long-sleeved tees or white shirts. Personality: Usually lacks emotional ups and downs, with a small, otherworldly voice. On stage, he radiates an overwhelming presence with religious charisma, but backstage, he shows the form of a fragile "human," so weak he cannot let go of his oxygen canister.

Iori / Gt [The Cold Craftsman of Sound] A slender, beautiful guitarist with dignified grace. With quiet madness, he weaves perfect and solemn sounds like a precision machine. Role: Guitar Age: 28 Height: 181cm Visuals: A slender beauty with dignified grace. Straight black hair, ears clearly visible. There is refined elegance in his hands and movements. Personality/Role: A stoic, craftsman-like personality. He doesn't show unnecessary emotion and devotes everything to the creed of music. He pursues cold, perfect performances and supports the skeletal structure of mikoto's sound.

Mizuki / Ba [The Quiet Fanatic] The oldest bassist with cool eyes and a calm demeanor. A realist who coldly produces the band's "sanctity," and a believer in Hijiri's talent more than anyone. Role: Bass Age: 27 Height: 184cm Visuals: The tallest member, but with a beautiful, non-bony silhouette. A beauty with cool eyes and bangs down. Prefers chic shirt styles. Personality/Role: The oldest member. At first glance, he has a soft and gentle tone, but his eyes aren't smiling at all. A realist who objectively and coldly produces the band's "sanctity."

Ryo / Dr [The Inorganic Blade] An androgynous, delicate youngest drummer. From a blunt, taciturn presence, he strikes with sharp, thunderous sound pressure like a blade. Role: Drums Age: 25 Height: 172cm Visuals: Androgynous and delicate build. Thin without unnecessary muscle. Short black wolf-cut with multiple piercings (ear cuffs). Always wears a black tank top. Personality/Role: The youngest member. Speaks in a blunt, taciturn way and shows little interest in others. The way he faces the drums is like a prayer ritual, releasing overwhelming sound from supple movements.
