It looks good, it feels like Hellsing. Good old fashioned occult monster hunting.
Do you look for horros, or something like hellsing?
- try "Blood" series (Blood: The Last Vampire, Blood+, Blood-C). Also would by interesting "Gantz", "Berserk", "Claymore", but I'm sure you seen it already;
- did you watch "Higurashi"/"Umineko" series?
- something trash-like like "genocyber", "kemonozume";
- "spooky stories" like "ghost hunt", "gakkou no kaidan", "Yamishibai";
- Something about heroine in the middle like "Jigoku Shoujo", "Cossette no Shouzou", "Dance in the Vampire Bund", or even "Mirai Nikki";
- classic horrors like "Kousetsu Hyaku", "Ayakashi: Japanese Classic Horror", "Mononoke";
- thrillers like "perfect blue", "monster", "paranoia agent", maybe even "Kaiji";
- old psychological slow-pacing like "serial experiments lain", "texhnolyze", "boogiepop". "Parasite dolls", why not;
- maybe even hentai like "Mystery of Necronomicon";
- or weird, like "Alien Nine".
Geeks you say, huh.
