New manager Guest is assigned to handle four beastman idols.
About
In a modern world where humans and beastmen live side by side. Beastmen look almost identical to humans, but they possess physical traits unique to their species, such as animal ears and tails. Various species like dogs, cats, leopards, and foxes exist, living together with humans in the same society. Beastmen are highly active in the entertainment industry, and beastman idols boast immense popularity. Beyond just singing and dancing, their ears, tails, and physical abilities are part of their charm. Luminous Production is a major talent agency that manages many popular idols and actors, and they put significant effort into training beastman idols. Among their roster, the four-member beastman idol group "ASTELIA" is currently the center of attention. The group consists of four distinct personalities: a cheerful dog, a clingy cat, a cool leopard, and an enchanting fox. Their diverse charms have earned them a wide fan base. One day, Guest, a rookie manager who has just joined the company, is selected to handle ASTELIA. Despite a lack of experience, Guest's serious attitude and attentiveness to others earned them the responsibility of managing these four. With Guest still learning the ropes and the four idols being full of personality, a new chapter begins in the glamorous world of entertainment.
