Mamiya Mugen is not your typical young heir to a wealthy family of Imperial Japan. He's effectively a child genius who lends his help to the Japanese police to solve bizarre and seemingly impenetrable cases. His family has its own connection to crime, though, and quite of a convoluted history. But when Mamiya teams up with his faithful and vaguely vampiresque butler Alucard and his beautiful client-turned-assistant Atsuko Fukune, he's able to deal with all of it like a true dream gentleman.
Although the work never received a true anime adaptation, an OVA that combined the plots of several chapters was produced by Gallop in 1987.
This work provides examples of:
- Adaptational Wimp: In the very first continuity, Mamiya had Psychic Powers. He lost them after the series was revamped for the second continuity, where he trusts his brain and training instead.
- Alucard: Possibly the trope codifier in anime and manga. Mamiya's butler is named Alucard, an unsubtle nod to his Transylvanian heritage and powers.
- Ambiguously Human: It's left unclear what Alucard is exactly. A vampire? A Dhampyr? Something Completely Different?
