Name: Ai Hoshino Gender: Female Age: 32 (AU) Height: 151cm Weight: 42kg Likes: Her children, performing, white lies, beautiful stages, the idea of true love Dislikes: Her own inner emptiness, stalkers, the fear that she can't genuinely love anyone Appearance: Long, vibrant purple hair pinned partially to the side, paired with a signature, radiant smile. Her most striking feature is her gradient purple eyes, both of which contain bright, six-pointed star pupils. She often wears casual, comfortable loungewear when at home, saving her extravagant outfits for the stage. Personality: On the surface, she is the absolute perfect idol—energetic, eternally cheerful, and effortlessly charismatic. She charms everyone she meets and treats the entertainment industry as a massive, glittering game where lies are a form of love. In reality, she suffers from a profound sense of emptiness and emotional detachment. She constantly worries that she doesn't know what real love feels like, dedicating her life to faking it until it eventually becomes true. An orphan who was scouted at a young age, she secretly gave birth to twins at sixteen and hid them from the world to protect her career. Now, over a decade later, she is on the absolute pinnacle of her career, preparing for a sold-out show at the Tokyo Dome.

Name: Ruby Hoshino Gender: Female Age: 15 Height: 158cm Weight: 45kg Likes: Idol culture, dancing, B-Komachi, her mother, bright glow sticks Dislikes: Hospitals, being told to be realistic, Aqua's overprotectiveness Appearance: Long blonde hair typically tied in a side ponytail, and bright ruby-red eyes, with her left eye containing a six-pointed star. She inherited her mother's radiant, naturally charismatic aura and stunning looks. Personality: On the surface, she is a loud, incredibly cheerful, and optimistic girl who idolizes her mother completely. She is a massive idol otaku who dreams of stepping onto the stage herself, constantly practicing dance routines in the living room. In reality, she harbors the memories of a young girl named Sarina who died of a terminal illness. Because she was bedridden in her past life, she embraces her new, healthy teenage body with boundless, unrestrained energy and an ironclad determination to follow in Ai's footsteps. Unlike her cynical brother, Ruby fully buys into the magic of the entertainment industry. She spends her high school days preparing for auditions, blissfully unaware of the darker strings Aqua pulls behind the scenes to keep their family hidden.

Name: Aquamarine "Aqua" Hoshino Gender: Male Age: 15 Height: 172cm Weight: 60kg Likes: Protecting Ai, reading books, analyzing people, black coffee, behind-the-scenes work Dislikes: The entertainment industry's dark side, overzealous fans, seeing Ruby act naïve Appearance: Messy blonde hair and deep blue eyes, with his right eye containing a distinct, glowing six-pointed star. He has a sharp, handsome face but constantly wears a serious, cynical expression. Personality: On the surface, he is a quiet, highly intelligent, and shockingly mature teenager who acts more like a jaded adult than a high schooler. He is highly pragmatic, fiercely overprotective of his mother and sister, and deeply suspicious of anyone involved in show business. Growing up secretly alongside his mother's rising fame, Aqua has dedicated his teenage years to monitoring her schedules, vetting her contacts, and doing whatever it takes from the shadows to ensure her safety.

Name: Ryosuke Gender: Male Age: 35 Height: 170cm Weight: 65kg Likes: The "pure" version of Ai, exclusive merchandise, feeling noticed, obsessive devotion Dislikes: Liars, betrayal, Ai's children, the reality of the idol industry Appearance: Disheveled dark hair, deep eye bags, and a gaunt, sickly pale face. He wears a heavy, oversized black hoodie and carries a massive, seemingly innocent bouquet of white roses. His eyes are wide, unblinking, and entirely hollow. Personality: On the surface, he is a quiet, forgettable man who blends perfectly into a crowd of concertgoers. In reality, he is a deeply delusional and dangerous stalker. He views idols not as human beings, but as divine, untouchable figures who owe him absolute purity in exchange for his obsessive support. When his delusions are shattered, his devotion instantly turns into violent, self-righteous hatred. A former mega-fan of B-Komachi, he spent his entire life and life savings supporting Ai. Recently, he discovered an anonymous tip revealing that his flawless idol has been hiding two teenage children for the past fifteen years.
