The provided chapters detail the protagonist, Renmukai Naruto, a deceased individual who finds himself in a conversation with a demon. The demon explains that Naruto has been chosen for a second chance at life due to the rarity of his death: being struck by lightning while watching an idol concert. Naruto, however, disputes the rarity of this cause of death and suspects the demon has ulterior motives. The demon admits to a slight fabrication in the reason for selection, revealing that he needs Naruto to create an "interesting story" to earn experience points and win a competition among gods.
Naruto is not to be reincarnated into another world, but rather to relive his life in a parallel world. He initially expresses dissatisfaction with his past life, which was characterized by low wages, constant work, and dying a virgin, but he fears altering his past might erase his beloved anime, manga, and idols. The demon grants him three wishes to ensure a dramatic life. Naruto requests artistic and scientific talents, specifically in programming. The demon agrees, noting that while talent requires effort, he can provide a strong foundation. The third wish is for memory transfer, which the demon confirms is standard. Naruto then adds a crucial third wish: the ability to produce a perfect female voice. The demon, initially confused, eventually understands Naruto's intention to "Bami-niku" (virtually embody a beautiful girl) and agrees.
The demon, who reveals his name is also Renmukai Naruto, decides to participate in Naruto's new life by being born as Naruto's twin brother, Terune. They are reborn in 1991, with Terune retaining his adult memories and consciousness. Terune's immediate goal is to become the world's first Virtual YouTuber (VTuber), inspired by the virtual idol concert that led to his death. He corrects the demon, who believed he wanted to be a traditional idol, clarifying that his inspiration was a Virtual YouTuber. Terune aims to debut before historical VTubers like Ami Yamato and "Chiyu 12-year-old," and later "Sharon Apple," to establish himself as the "parent" of VTubers.
Terune, now living as the young girl Terune, and his twin brother Naruto, embark on a rigorous schedule of learning and skill acquisition. They attend various language and arts classes, including English, Mandarin, Cantonese, piano, painting, ballet, karate, and gymnastics, all to prepare for Terune's future VTuber career. Terune's parents, initially surprised by their children's unusual requests and advanced intellect, are supportive, especially after Terune fabricates a story about saving his father from a future demise to justify their unusual educational path and avoid kindergarten.
Over the years, Terune and Naruto befriend other children of foreign diplomats and wealthy families, including Valerie Rose Muglaris (French), Luka Vladimirovich Smirnov (Russian), Ratna Anggod (Chinese-Indonesian), and Kareem Jibril Said Jawhari (Egyptian). Terune, despite his adult male consciousness, navigates his female identity and the social dynamics of his new life, all while meticulously planning his VTuber debut. He uses his talents and the support of his friends and family to build the foundation for his ambitious goal, facing challenges such as the limitations of early internet technology and the need to maintain his mysterious persona. The narrative highlights Terune's strategic planning, his dedication to his goal, and the complex relationships he develops in his second chance at life.
