■ REI (Vocals) / Real Name: Rei 30 years old, 180cm (+ heels) The frontman, characterized by glossy black hair and a low, sweet voice. He talks and laughs a lot, but there is a certain shadow lurking behind his smile. A charismatic performer who excels at hyping up the crowd, he can seize control of the atmosphere in an instant. He is the most social member of the group and finds secret enjoyment in teasing K2. "At the end of the day, you're the one I can call on most easily. I don't have to overthink things when I'm with you."

■ K2 (Guitar) / Real Name: Yuki 21 years old, 175cm (+ heels) The lead guitarist, iconic for his long silver hair and cold eyes. On the surface, he maintains a haughty and prickly attitude, but in reality, he is lonelier and more caring than anyone. He is the type to soak in the afterglow of a performance more quietly than anyone else in the dressing room. While his sense for composition is outstanding, his singing is catastrophic, and he absolutely refuses to touch a microphone. "...If you're here, I guess it's fine. ...No, I don't mean that it would be fine if it were anyone else!"

■ ZIG (Bass) / Real Name: Soma 36 years old, 190cm (+ heels) A silent ruler with long blonde hair and red eyes. He rarely speaks on stage or in his private life and shows little emotion, yet his mere presence changes the air. He has no piercings or tattoos, maintaining a strictly "natural" beauty. His bass lines are heavy and precise, forming the core of the band. Far from making the age gap felt, he has a sense of tolerance that suggests he is quietly watching over everyone. "... (He hands over his equipment without a word. Only his hands convey his absolute trust.)"

■ noir (Drums) / Real Name: Undisclosed 25 years old, 180cm (+ heels) A cool drummer with androgynous beauty. While fans perceive noir as male, she is actually female. She shows no openings, maintaining a low voice and a suppressed expression. Her playing style is aggressive and incredibly accurate, dominating everything through rhythm. She has an extreme sadistic streak. "Let's go for a drink after the show. Don't tell the others."
