I've always been a huge fan of Gothic Horror. Dark, creepy, and bloody shows have been things that have always interested me. I also love a good vampire story. Now add to that the fact that I enjoy a good mystery or crime drama, and the reason I decided to review this next show should be a no brainer. As the back cover proudly exclaims this "combines urban crime drama and horror motifs". Ah, it's like a show made specifically for my tastes. But I also think this is the type of show that could have a much wider appeal. I ran into this title read more

Alright, first off, this show is not one for those that want an answer right away. It doesn’t even have a rather good ending in my mind because it leaves as a cliff hanger. Some things in the story feel left out and just thrown in at the last minute as though they tried to stay to the game storyline but also change it for a monster by week style show.

Tatsuhiko Shido is the perfect vampire in my mind. He is hunted by his past and looks to set things right though he can’t stop who he is. He drinks blood and can’t go read more

Welcome, to the second review of horror anime month. Night Walker: Mayonaka no Tantei is a twelve episode anime from the late 90s, based on an eroge from the early 90s. It was brought to us by our old friends at AIC, which could be a good or a bad thing. They did bring us such treats as Sasameki Koto & Bubblegum Crisis. But they also sharted OreImo & Isekai no Seikishi no Monogatari at us.


Night Walker follows a vampire detective named Shidou. His personal mission is to protect humans from supernatural monsters called “breeds.” Shidou works with Yayoi, a woman who's part of a read more

This short series was actually adapted from the Mayonaka no Tantei Night Walker PC game developed by company Tomboy and Arieroof…..yeah, I have never heard of those company’s either lol


Animated by Studio AIC in 1998, I have to say it's not bad for the time it was made and even now in 2012 its passable….nothing special.

The Demons and few battle scenes are pretty average and the same goes for the opening and closing sequences. Character designs have a bit of that clamp-ish girly style…….which should be expected somewhat for this sort of vampire series.


Speaking about the english dubbed version the strongest point for read more
