Night Walker: The Midnight Detective

Aired: 1998

A dark mystery anime centered on Yotarou Yotsuya, a vampire who runs a detective agency. He investigates bizarre cases caused by shadowy creatures called Nightbreeds, using his blood-based powers alongside classic detective reasoning. Atmospheric art, stylized direction, and the protagonist's quiet solitude between human and inhuman worlds anchor the show, which mixes episodic mysteries with an overarching narrative. Produced by AIC, it stands as a pioneering adaptation of an adult-game property for television anime.
