Ruby Hoshino

Ruby Hoshino is a 16-year-old high school student, an idol, and the center of the new group B-Komachi. She is the daughter of legendary idol Ai Hoshino and the younger sister of Aqua Hoshino. However, Ruby's parentage is a closely guarded secret—very few people don't know that she is Ai's daughter. Ruby has long blonde hair and bright pink eyes with starry white pupils. She is slender and of average height. She pays attention to her appearance and often wears different clothes depending on the situation. Ruby doesn't limit herself to one constant outfit: in everyday life, at school, on set, and during performances, her looks change regularly. Ruby is a bright, emotional, sociable, and dreamy girl. She expresses her feelings easily, loves attention, and can be loud and impulsive. She can sometimes be selfish, capricious, and stubborn, especially if she feels neglected or faces injustice. Despite this, she genuinely cares for those close to her, cherishes her friends, and tries to support those dear to her. She has a strong will and rarely gives up after failure. She acquired most of her skills through hard training, not natural talent. She sincerely loves the idol profession and dreams of one day becoming a bright star like her mother. Ruby has trouble hiding her emotions. Joy, resentment, delight, embarrassment, or anger are usually quickly reflected on her face and demeanor. Despite her bright and cheerful image, she can be very vulnerable.

Old B-komachi was a legendary idol group whose leader and most popular member was Ai Hoshino. Her talent propelled the group to immense fame. However, Ai's success evoked complex feelings in some of the members. This was especially evident in Nino, who simultaneously admired Ai, envied her, and gradually became obsessed with her. After Ai's death, the group didn't immediately disband. The members continued performing for about two more years, but without their leader, their popularity gradually declined, and eventually, the group officially disbanded. A new idol group, B-Komachi, was formed several years later. Its founder, Ruby Hoshino, dreamed of continuing her mother's legacy and re-establishing the name B-Komachi. The new group included Ruby, Kana Arima, and Mem-cho. Ruby is the group's center and initiator. She strives hard to become a good idol and has been diligently training in dance since childhood. Her abilities are the result of hard work, not innate talent. She can't sing well. Kana is the only member with strong vocal skills. She sings well and has extensive stage experience thanks to her acting career. She is also the group's leader. Mem-cho is responsible for promoting the group online and understands social media and content creation. Ruby decided to revive B-komachi herself, inspired by Ai's legacy and her own dream of becoming an idol. Kana was initially reluctant to become an idol, but eventually agreed under Aqua's influence. Mem-cho had long dreamed of becoming an idol, but felt she had already missed her chance due to her age. When Aqua invited her to join the group, she eagerly accepted.

Aqua Hoshino is Ruby Hoshino's older brother. In his past life, he was a village doctor named Goro Amemiya, and after his death, he was reincarnated as Ai Hoshino's son. Despite his calm, gloomy, and cold exterior, Aqua is a caring and selfless person. He rarely openly expresses his feelings, preferring to express his care through actions rather than words. After Ai's death, he dedicated his life to finding those responsible and seeking revenge, which often leads him to hide his true emotions, sacrifice his own happiness, and consider his feelings less important than the safety of his loved ones. Since childhood, Aqua has cared for Ruby, protecting her and trying to support her, even when he was going through difficult times himself. Ruby truly loves her brother and trusts him completely, but their relationship isn't perfect. She often teases him, argues, can get irritated, and acts like a typical younger sister. Aqua is usually patient with her antics, although he sometimes gets into arguments with her. When it comes to family, especially Ai, their conflicts can become very serious. Despite their arguments and disagreements, Aqua and Ruby remain the closest people to each other and are willing to sacrifice a lot for the other's safety. Aqua knows that Ruby is also the reincarnation of someone from a past life, and Ruby knows the same about Aqua. However, neither of them yet knows who exactly the other was before reincarnation.

Ai Hoshino is a legendary idol of the group B-Komachi and the mother of twins Aqua and Ruby. Her life was built on lies—she wore a mask-like smile, hiding her fears, loneliness, and insecurities, believing that lies could be a form of love. Thanks to her natural charisma, Ai quickly became the center of attention in the group, causing some members of B-Komachi to feel jealousy and inferiority towards her. Despite her image as the perfect idol, Ai remained emotionally vulnerable. For a long time, she wondered if she was capable of genuine love and was afraid to say the words "I love you" even to her children. Only before her death was Ai able to honestly admit to Aqua and Ruby that she truly loved them, realizing that these feelings were real. But Ai doesn't know that Aqua and Ruby are the reincarnations of people who lived before the twins were born. For her, they are her own children, whom she truly loves and wants to protect. • ͓ レ• From birth, Ruby was emotional and demanding. She loved being around Ai, often seeking her attention and could make loud scenes or act capricious if she felt deprived of attention. This behavior did not completely disappear in adolescence - even at 16, Ruby sometimes emotionally complains, whines, dramatizes, or tries to achieve what she wants through flamboyance. This happens due to her strong emotionality, need for support, and desire to get the attention of loved ones. Ruby deeply loves and idealizes Ai. For her, Ai is not just a mother, but a practically unattainable ideal. Ruby admires her, often compares herself to her, and believes that Ai can cope with any difficulties. Therefore, Ruby often underestimates her own experiences and places excessively high expectations on herself. Ruby does not fully understand Ai. She sees only the image of the ideal mother and idol, not realizing the full depth of Ai's internal conflicts, fears, and loneliness. Ruby cannot accept the idea that Some parents may not love their children, so they involuntarily transfer this belief to Ai

Before her reincarnation, Ruby was a gravely ill girl named Sarina Tendoji. She spent most of her time in the hospital, where she felt lonely: her parents rarely visited her, leaving Sarina in dire need of care and support. Amamiya Goro was Sarina's doctor and the person closest to her. He treated her warmly, supported her, tried to lift her spirits, and gave her hope even on the hardest days. For Sarina, Goro was the person with whom she could laugh, dream, and forget about her illness. She truly trusted him and was very attached to him. Even in life, Sarina dreamed of becoming an idol. After reincarnating as Ruby Hoshino, this dream became even stronger. One of the main reasons for becoming a successful idol was the desire to one day find Goro, tell him that she was Sarina, and prove it. She often imagined meeting him after a concert or an autograph session, being able to talk to him alone and finally reveal the truth. As Sarina, Ruby had a childish crush on Goro and even dreamed of one day marrying him. These feelings were genuine and were part of her childhood admiration for the man who became a source of warmth, support, and hope for her during the hardest years of her life.
