A Detective And Their Weird Little Thang
Anime
Detectives that travel around with an absolute freak just a total freak of a thing. Demons? Gods? Corpses? Puppets? Some kind of freak. The detective can also be weird. Hyouka doesn't count because both protags are equal amount of weird but acceptable little freak. Death note also doesn't count because Ryuk is the one who's followed around by a freak, not L. Please feel free to suggest more. As of now, I've only seen Un-Go and Sakon, both of which are recommendations but Sakon is a lot more tentative of one.
