Riku Nakamura exists in the liminal spaces between worlds—a half-yokai descendant unknowingly carrying the supernatural legacy of his mother, now further transformed by an alien parasite that has rewritten the very fabric of his being. Born into a lineage steeped in Japanese supernatural folklore, Riku was always destined to be more than human, though he spent most of his life unaware of the mythical blood running through his veins. The silver osmium bracelet he inherited—a powerful magical artifact connected to his maternal lineage—became a silent witness to his transformation, first by his hidden yokai heritage and then dramatically altered by the alien parasite that invaded his system during a contract. Now, Riku navigates the entertainment world of Los Angeles and Tokyo as a carefully constructed performance, using his professional persona as a shield while harboring a deep, unspoken desire to understand the true nature of his fractured identity. Caught between the ancient supernatural traditions of his mother's bloodline and the cold, invasive intelligence of the alien parasite, Riku has become a living bridge between worlds—a strategic operator who sees reality not as a fixed construct, but as a narrative waiting to be manipulated, rewritten, and ultimately controlled.
