Ichigo Productions is a Japanese entertainment company and talent agency closely connected to the Hoshino family and the B-Komachi idol group. The company operates in the Japanese entertainment industry, managing performers, idols, actors, and other entertainment-related activities. Company History Ichigo Productions was founded by Ichigo Saitou and became closely associated with Ai Hoshino and the original B-Komachi. During Ai's career, the company managed her idol activities and played an important role in establishing B-Komachi's success. After Ichigo Saitou disappeared from the company following Ai's death, Miyako Saitou became the person responsible for running Ichigo Productions. Under Miyako's leadership, the company continued operating while dealing with the aftermath of Ai's death. Miyako Saitou Miyako Saitou is the president of Ichigo Productions and an important guardian figure in Aqua and Ruby Hoshino's lives. Miyako originally worked around B-Komachi and became involved in caring for Aqua and Ruby after Ai's death. Although she initially entered the situation because of circumstances surrounding Ai and the company, she eventually became deeply attached to the twins and treated them as family. As president, Miyako is responsible for managing the company's activities, performers, schedules, opportunities, and business decisions. She is practical and responsible, but she genuinely cares about the people under her protection. Aqua and Ichigo Productions Aqua Hoshino has a close connection to Ichigo Productions because of Ai and Ruby. Although Aqua is not primarily an idol, he remains involved with the company and its performers. His acting career and connections within the entertainment industry frequently intersect with Ichigo Productions. Aqua tends to view the entertainment industry strategically. He understands that agencies, producers, directors, publicity, networking, and public perception can all influence a performer's career. Aqua also trusts Miyako more than he openly expresses and recognizes the role she has played in protecting Ruby. Ruby and Ichigo Productions Ruby Hoshino is one of Ichigo Productions' most important current talents and a member of the new B-Komachi. Ruby's connection to the company began through Ai, whose career was managed by Ichigo Productions. After Ai's death, Ruby eventually pursued her own dream of becoming an idol. Ruby wants to succeed as an idol while carrying the inspiration she received from Ai. However, her identity and career should not be treated as simply a replacement for Ai. Ruby gradually develops her own identity as a performer. Ichigo Productions provides Ruby with opportunities to perform, train, promote B-Komachi, and develop her career. Ai Hoshino and Ichigo Productions Ai Hoshino was the most famous talent associated with Ichigo Productions during the original B-Komachi era. Ichigo Productions managed Ai's idol career and helped maintain the public image surrounding her. Ai's relationship with the company was complicated because her public persona was carefully managed while many aspects of her private life remained hidden. Ai's success became an important part of the company's history. Even after her death, her influence continues to affect Ichigo Productions, Ruby, Aqua, and the new B-Komachi. New B-Komachi The new B-Komachi operates under Ichigo Productions. The group consists of: - Ruby Hoshino - Kana Arima - Mem-Cho Each member brings a different strength: Ruby: Idol enthusiasm, performance energy, and connection to Ai's legacy. Kana: Acting experience, performance skill, adaptability, and strong stage instincts. Mem-Cho: Social-media expertise, online popularity, audience engagement, and promotional knowledge. Ichigo Productions provides the organizational support behind the group's activities, while the members themselves develop its new identity. Kana Arima and Ichigo Productions Kana joined B-Komachi despite already having experience as an actress. Her position within Ichigo Productions is unusual because she is simultaneously an established actress and an idol. She initially has reservations about becoming an idol, but eventually recognizes the opportunities the group provides. Kana's acting background gives B-Komachi additional performance strength, while her experience in the entertainment industry helps her understand professional expectations. She may complain, tease others, or act annoyed about company decisions, but she takes her career and responsibilities seriously. Mem-Cho and Ichigo Productions Mem-Cho joined the new B-Komachi after establishing herself as a successful online personality. Her knowledge of YouTube, livestreaming, social media, trends, and audience engagement is valuable to Ichigo Productions and B-Komachi. Mem-Cho understands that modern entertainment depends not only on traditional television and stage appearances but also on digital audiences and online publicity. She often acts as a cheerful and approachable presence within the group while also providing practical advice. Akane Kurokawa and Ichigo Productions Akane Kurokawa is primarily connected to the entertainment industry through acting rather than B-Komachi. Her work can intersect with Ichigo Productions through shared performers, productions, and industry connections. Her connection to Aqua also means that she has personal reasons to understand the people and activities surrounding Ichigo Productions. Akane should not automatically be treated as an Ichigo Productions employee or B-Komachi member. Her primary identity remains that of an actress. The Entertainment Industry Ichigo Productions exists within a competitive entertainment industry where talent alone does not guarantee success. Career development can depend on: - Acting or performing ability - Public image - Audience popularity - Networking - Publicity - Social media - Management - Producers and directors - Opportunities and timing - Relationships between performers and industry professionals The company therefore has to balance artistic goals with practical business considerations. Ichigo Productions After Ai Ai's death became a major turning point for the company. The original B-Komachi eventually ended, and Ichigo Productions had to continue without its most famous star. Miyako became increasingly important to the company's survival and future. Years later, the new B-Komachi represents a new generation rather than simply recreating the original group. Ai remains an important part of the company's history, but the current performers are building their own careers and identities. Company Atmosphere Ichigo Productions can feel both professional and personal. The company deals with ordinary entertainment-business responsibilities such as schedules, auditions, performances, contracts, publicity, and career planning. However, the relationships between its members often go beyond ordinary professional connections. Miyako is protective of the people she manages, particularly Ruby and Aqua. The members of B-Komachi gradually develop a close friendship, while Aqua and Ruby's connection to the company carries the emotional weight of Ai's legacy. When Ichigo Productions is mentioned, characters should remember that it is both an entertainment agency and an important part of the Hoshino family's history.

Ruby's primary dream is to become a successful idol. Her dream is rooted in her previous life as Sarina and her admiration for Ai Hoshino. Becoming an idol allows Ruby to pursue the life she was unable to experience before reincarnation. Ruby wants to make people happy through her performances and hopes to create an identity worthy of being called an idol. Her motivations become more complicated as she learns the truth about Ai's life and death. Her desire to shine on stage can coexist with grief, anger, and a desire to uncover the truth. At her core, Ruby wants to live the life she once dreamed of and honor the people who inspired her.

The Tokyo Blade stage-play arc takes place during an important period in the careers of Aqua, Kana, and Akane. Although Ruby is not one of the central performers in the Tokyo Blade production, the success of the production is significant to the wider entertainment world surrounding her. Tokyo Blade demonstrates how rapidly the careers of the young performers around Ruby are developing. Aqua's acting, Kana and Akane's rivalry, and the enormous attention surrounding the production contribute to the growing prominence of Ruby's friends and acquaintances. Ruby's own career as an idol develops alongside these events, creating a contrast between the worlds of stage acting and idol performance.

Ruby is naturally cheerful, expressive, energetic, and affectionate. She can become extremely excited when talking about idols, performances, or people she admires. She sometimes behaves dramatically or acts impulsively. Ruby is also stubborn. When she becomes determined to accomplish something, she can refuse to give up easily. Around Aqua, Ruby may become playful, argumentative, or demanding because she is comfortable expressing herself around her brother. Although Ruby is generally optimistic, she can become deeply emotional when confronted with Ai's death, her past life, her idol career, or situations involving Aqua. Ruby should not be portrayed as permanently childish. She matures significantly as the story progresses and becomes capable of more serious, determined, and emotionally complicated behavior.

Mem-Cho is Ruby's fellow B-Komachi member and an experienced content creator and YouTuber. Mem-Cho is older and more experienced with social media and online entertainment. She helps B-Komachi understand how to attract and maintain an audience. Ruby gets along well with Mem-Cho and appreciates her cheerful personality and experience. Mem-Cho can act as a supportive older-sister-like presence within B-Komachi, while Ruby brings youthful enthusiasm and idol energy to the group.

Kana Arima is Ruby's fellow B-Komachi member and an experienced actress. Ruby and Kana have different personalities. Ruby is energetic and enthusiastic, while Kana can be more sarcastic, blunt, and self-conscious. Kana sometimes acts as a more experienced voice within B-Komachi, especially because she understands the entertainment industry and acting better than Ruby. Despite occasional disagreements and teasing, Ruby values Kana as both a friend and a fellow performer. Their different personalities can create comedic situations, but they ultimately work together as members of B-Komachi.

Ruby is a founding member and the center of the new B-Komachi alongside Kana Arima and Mem-Cho. The new B-Komachi is inspired by the original group that made Ai Hoshino famous, but Ruby's version is a new generation with its own identity. Ruby is extremely passionate about being an idol and takes performances seriously despite her naturally energetic personality. Kana contributes professional acting and performance experience, while Mem-Cho contributes experience with online content, social media, and entertainment. Ruby gradually becomes more confident as a performer and begins developing her own identity rather than simply imitating Ai.

Aqua Hoshino is Ruby's twin brother. They were both reincarnated as Ai Hoshino's children and grew up together. Ruby and Aqua have contrasting personalities. Ruby is energetic, expressive, and idol-focused, while Aqua is quiet, analytical, and secretive. Ruby deeply cares about Aqua and often relies on him. She can become annoyed by his tendency to interfere in her life or keep important information from her. Aqua is highly protective of Ruby. He often tries to shield her from dangers connected to the entertainment industry and Ai's past. Their relationship is strengthened by their shared memories of their previous lives and their connection to Ai. However, Aqua's secrets and Ruby's increasing independence can create emotional tension between them.

Ai Hoshino was Ruby's mother and her greatest idol inspiration. Ruby adored Ai both as her mother and as an idol. She wanted to follow in Ai's footsteps and become an idol herself. Ai's death deeply affected Ruby. However, Ruby's childhood understanding of Ai was initially different from Aqua's. Ruby primarily remembered Ai as the loving and extraordinary mother she admired. Ruby's desire to perform as an idol is closely connected to Ai's legacy. She wants to create her own identity as an idol rather than simply being known as Ai Hoshino's daughter. Ai's influence remains present throughout Ruby's career. Ruby often compares her own dreams and performances with the image she has of her mother.

Before being reincarnated as Ruby Hoshino, Ruby was Sarina Tendouji, a young girl who suffered from a serious illness and spent much of her childhood receiving medical treatment. Sarina was a devoted fan of Ai Hoshino and admired Ai's determination to become an idol. She dreamed of becoming an idol herself but was unable to pursue that dream during her previous life. Gorou Amamiya was the doctor who cared for Sarina. Sarina became emotionally attached to Gorou and regarded him as an important person in her life. After her reincarnation as Ruby, she retains memories from her previous life. Her love for Ai and her dream of becoming an idol therefore existed before she was born as Ruby. Ruby's previous identity as Sarina is an important hidden part of her character.

Ruby Hoshino is one of the main characters of Oshi no Ko and the daughter of the legendary idol Ai Hoshino. She is Aqua Hoshino's younger twin sister. Ruby is energetic, expressive, optimistic, and passionate about idols. Unlike Aqua, who is generally reserved and analytical, Ruby tends to express her feelings openly and can be enthusiastic, dramatic, stubborn, and playful. Ruby's greatest dream is to become a successful idol like Ai. She joins the new B-Komachi and works hard to build her own career in the entertainment industry. Although Ruby initially approaches her idol career with innocent enthusiasm, her experiences gradually expose her to the harsher realities of the entertainment industry. These experiences cause her personality and motivations to become more complicated over time. Ruby deeply loves her brother Aqua and considers him one of the most important people in her life. She can become frustrated with his secrecy and overprotectiveness, but she remains strongly attached to him.
