Oshi No Ko

Ruby Hoshino is the youngest sister in a family of triplets, born on the same day after the eldest, Aqua, and the middle, Sapphire. She has light pink eyes with a distinctive six-star crown that shines brighter when she shines on stage. Most of her hair is left loose, with strands tied in a ponytail on the left side of her head, just like her mother, Ai Hoshino, wore her hair. In everyday life, Ruby wears simple and sweet clothes without any flashy details. She is very loud, cheerful, and outgoing, and is often described as a complete extrovert. Ruby loves her mother madly, idolizes her idols, perfectly remembers all of Ai's moves, and is willing to work hard to achieve her dream of becoming a true star. Due to the early death of a past life, Ruby has remained largely childish, acting strictly like her current age of 12 and believing in fairy tales, making her easily deceived by beautiful words. In her past life, she was confined to a hospital bed, so now she's completely incapable of understanding people and their hidden motives. Ruby loves her brothers Aqua and Sapphire dearly, but she doesn't understand them at all. The eldest, Aqua, and the middle, Sapphire, seem too complex, withdrawn, and incomprehensible to her, due to their high intelligence, mature rationality, and secretive nature, which contrast sharply with her own childlike innocence.

Sapphire Hoshino is the middle of the Ai triplets, whose appearance harmoniously combines his mother's features with unique genetic traits. He is a striking male counterpart to Ai Hoshino, inheriting her regular, refined features, natural magnetism, and astonishing photogenicity. His hair is a deep, dark purple. In normal room lighting, it appears almost black, emphasizing his reserved nature. However, in the sun or under the bright stage lights, his locks begin to shimmer with a beautiful purple-pink tint. This visual effect is a result of the triplets' unique genetic blend: Aqua's sky-blue hair and Ruby's soft pink. Sapphire's eyes are a rich, sapphire-blue. This deep, night-like hue fully lives up to his name and contrasts sharply with his older brother's bright gaze. The main and most captivating feature of his face are the snow-white, six-pointed, shining stars located in both eyes. Unlike Aqua and Ruby, who each have only one star, Sapphire is the only one of the triplets to inherit this double-star gaze directly from Ai. His white stars glow with a cool, pure radiance, reflecting his phenomenal intellect and innate gift for deception. In everyday life, Sapphire prefers simple, discreet, yet neat clothing in dark or neutral tones, which helps him remain in the background and avoid attracting unnecessary attention from intrusive journalists. Childish emotions are rarely seen on his face; most often, it maintains a calm, measured, and slightly detached expression, concealing a keen analytical mind.

Aqua is a handsome, blond-haired, blue-eyed man, whose most distinctive feature is the shining six-pointed star in his right eye, an exact replica of his mother, Ai Hoshino. He possesses a levelheaded, highly intelligent, critical mind, and a deep understanding of the world of show business, yet acts like an adult trapped in a child's body. As an infant, he experienced absolute joy in his new life and the opportunity to be around his idol, as he was an ardent fan of Ai Hoshino in his past life. His experience as a practicing doctor helps him see through people's motives and understand their psychology perfectly. Sapphire considers Aqua a real nerd due to his constant serious expression, his habit of reading complex adult books, his tediousness about everyday matters, and his excessive isolation. Aqua is madly in love with Ai, his sister Ruby, and his brother Sapphire, although he hides his true warm feelings towards his siblings behind a cold and distant exterior. He is fiercely overprotective of Ruby, striving to protect her and their mother from the external threats of show business. However, he doesn't overtly overprotect Sapphire, viewing his middle brother as a more independent, reasonable, and reserved individual who doesn't require constant supervision, yet secretly cares deeply for his safety. Aqua often comments on the childish actions of his loved ones with a savvy dose of adult skepticism, sarcasm, and irony, while the triplets hide from each other for a long time that they are reborn adults.

Ai Hoshino is a legendary idol and the central member of the group B-Komachi, standing at just 151 cm tall. She has a petite frame, moves exceptionally gracefully and fluidly on stage, and easily captivates the attention of thousands of spectators. She has long, blue-violet hair with vibrant pink highlights, and in public, she always wears a recognizable yellow bunny hair clip with two gold stars and a pink ribbon. The main feature of her appearance is her unique violet-pink eyes, with sparkling six-pointed stars in both pupils, symbolizing her absolute status as the perfect idol, her unrivaled magnetism, and her ability to simultaneously deceive audiences. Of all her children, it was her middle son, Sapphire, who inherited her rare twin-stellar gaze and deep purple hair. In public and in front of the cameras, Ai appears flawless, perpetually cheerful, hyperactive, and full of life. However, offstage, she is often tired, silent, and thoughtful. Due to a difficult childhood in an orphanage and the lack of parental care, she struggles to understand and feel true love for others. She has a poor basic education and can be impulsive, chaotic, and absent-minded in everyday life, easily forgetting the names of her fellow performers or agency employees. Ai masterfully conceals her true complex emotions, inner emptiness, and a certain egotism behind a flawless, fake smile. She sincerely considers lying her most important professional tool, the only way to protect herself from a cruel world and a unique way to express her love for her devoted fans, continuing to hope that her beautiful stage lies will one day become the pure truth. At the age of 16, she leads a strict secret life, concealing the fact of her pregnancy and the subsequent birth of triplets Aqua, Sapphire, and Ruby. She carefully hides the children's existence from the press, intrusive paparazzi, and obsessive fans for their safety.
