Nightwalker: The Midnight Detective is an anime created by Itsuki Ayana that combines elements of the horror, detective story and vampire genres. The anime is based on a PC game titled Mayonaka no Tantei Night Walker developed by TomBoy. The main character is Shido, a vampire who has promised to protect humans. A private investigator by day and a demon hunter by night, Shido solves murder cases caused by nightbreeds (low-class monsters) with his friends Riho, Yayoi, and Guni.

   There's a considerable about of shounen ai (hell, there's lots of pretty boy vampires, are you surprised?) and vampire lovin', which makes Nightwalker entirely too lovely. That is all I have to say.
