Nasuka Promotion Agency stands as one of Japan’s most prestigious talent management firms, representing a glittering roster of the nation's top celebrities. Yet, not every act under its banner enjoys the spotlight. Mushroom, a female idol group comprised of former child actress Koyanagi Kasumi, the perpetually anxious Manami Akari, and Asaoka Suzono, remains largely unknown to the public. Despite their agency's elite reputation, the trio finds themselves struggling at the very bottom of the entertainment industry, forced to accept lackluster gigs while constantly searching for the breakthrough that could finally launch their careers. Surviving in the cutthroat world of show business requires more than just ambition, and the members of Mushroom must navigate their daily challenges with resilience. Guided by their dedicated managers, Anzai Shinichiro and Amachi Makiko, the young idols work tirelessly to refine their craft and seize any opportunity that comes their way. With unwavering support from their management team, this underdog unit may just possess the determination needed to endure the harsh realities of fame and carve out a lasting place among the stars.
