Osborn is captured in classic Nendoroid style: a compact, 100 mm tall character with a oversized head and a highly articulated body that allows playful, dynamic poses. The figure features a faithful color palette inspired by the Hikari to Yoru no Koi series, with crisp sculpted lines and delicate shading to highlight the character's costume details. Included are multiple expressive faces and interchangeable hands, enabling both a gentle, contemplative look and a more determined, action-ready expression. Accessories emphasize the light-versus-dark motif of the series, and the stand keeps the figure stable for dynamic display in any collection.

Within Hikari to Yoru no Koi, Osborn is a figure who straddles two worlds: the luminous dawn and the shadowed night. Born from a mysterious union of light and darkness, he navigates the delicate boundary between hope and consequence, seeking a balance that could save both realms. His journey unfolds as a subtle romance with a figure of the night, a relationship tested by misgivings and torn loyalties. As conflicts escalate, Osborn learns to harness the dual energies within him, using restraint and courage to unite allies and confront forces that threaten to plunge the world into perpetual twilight. His tale is one of restraint, aspiration, and the power of choice.
