Leonhart, originally named Richard, governs Ozmargo as a half-human, half-beast monarch descended from a human mother and the late king’s twin brother. Raised by his uncle following his father’s demise, he endured relentless cruelty fueled by his guardian’s disdain for his human lineage, including monthly imprisonment during forced transformations under the full moon. In his human state, he manifests an androgynous physique with pale skin, waist-length black hair, crimson eyes, and faint horns, his arms scarred from self-inflicted wounds to mimic the slaughter of sacrificial victims. His beast form towers over two meters with a leonine frame cloaked in rich dark sienna fur, curved ram-like horns, and a sweeping tail.

Though feared as a tyrant, Leonhart masks a strategic mind and deep empathy, using calculated acts of ferocity to stabilize his fractured kingdom while covertly bridging Ozmargo’s warring beast clans. Tormented by self-loathing over his dual nature and societal scorn for humans, he finds unexpected solace in Sariphi, a human sacrifice who uncovers his secret and challenges his internalized shame. Her influence sparks a transformative shift, compelling him to openly reconcile his heritage and champion human-beast coexistence.

Behind his fearsome reputation lies a pacifist who spares sacrificial women through staged deaths, employing blade-marked floors and a clandestine escape tunnel to preserve their lives. His reforms dismantle species-based hierarchies, reversing his predecessors’ divisive policies to grant equal rights—a vision tested when his human form is exposed publicly, triggering a crisis of confidence. With Sariphi’s support, he reclaims his usurped throne, solidifying governance reforms and peace efforts.

Post-reign, Leonhart marries Sariphi, fathering three heirs: shape-shifting son Richard and twin daughters Shiira and Stella, who inherit his beast traits. His legacy as a unifier, amplified by Sariphi’s advocacy, reshapes Ozmargo’s future. The spin-off *White Rabbit and the Beast Prince* chronicles his ongoing dedication to family and societal harmony. His journey culminates in embracing vulnerability as power, symbolized by adopting “Leonhart”—a name merging his birth identity with the lionhearted resolve forged through love and leadership.
