The narrative centers around a young girl named Shiro Usagi, who lives in a world where humans coexist with anthropomorphic animal beings known as Kemono. Shiro, whose name translates to "White Rabbit," is a human with a mysterious connection to the Kemono, particularly to their prince, a powerful and enigmatic figure known as the Kemono no Ōji.

The story begins with Shiro encountering the Kemono no Ōji under unusual circumstances. The prince, who is both feared and revered by his kind, takes an immediate interest in Shiro, sensing her unique qualities. Shiro, on the other hand, is initially wary of the prince due to his intimidating presence and the rumors surrounding his ruthless nature. However, as the two spend more time together, a complex relationship begins to form, marked by mutual curiosity and a growing emotional bond.

The Kemono no Ōji is not merely a ruler but also a guardian of his people, tasked with maintaining the fragile balance between humans and Kemono. This balance is threatened by external forces, including rogue Kemono who seek to dominate both worlds and human factions that view the Kemono as a threat.

The narrative explores themes of coexistence, identity, and the blurred lines between humanity and monstrosity. Shiro's journey is one of self-discovery, as she navigates her dual role as a human with a deep connection to the Kemono. The Kemono no Ōji, meanwhile, grapples with his responsibilities as a leader and his growing affection for Shiro, which complicates his duty to protect his people.

Supporting characters include various Kemono who serve as allies or adversaries, each with their own motivations and backstories that enrich the world-building. The political intrigue within the Kemono society adds depth to the plot, as factions vie for power and influence. The series also delves into the history of the Kemono and their origins, revealing secrets that have far-reaching implications for both humans and Kemono alike.
