Case Closed: The Miracle of Excalibur

Case Closed: The Miracle of Excalibur is an original video animation released in 2012 as a promotional tie-in for the sixteenth feature film in the long-running Detective Conan franchise, titled The Eleventh Striker. Produced by TMS Entertainment, the OVA was bundled with limited editions of the film's home media release to expand upon the series' lore while providing fans with a self-contained mystery that bridges the gap between major theatrical events. It follows the series' established formula of combining lighthearted character interactions with an intricate, logic-based detective puzzle.

The animation reflects the high production standards of the studio's mid-2010s output, maintaining the aesthetic fidelity and character designs established by creator Gosho Aoyama. By focusing on side stories, the production team aimed to deepen the audience's engagement with the expansive cast of the Detective Conan universe beyond the high-stakes pressure of the main cinematic installments. While intended primarily for the established domestic Japanese fanbase, the work is noted for its adherence to the series' foundational tone and its contribution to the vast catalogue of supplemental material that defines the franchise's enduring popularity.
