Sankarea, Nisemonogatari Recommendations
Similarly trippy styles of direction. Protagonists who mess with the supernatural in somewhat serious ways. Fanservice. Fanservice. Fan. Service.
both is very good anime where the main protagonist deal with some supernatural stuff. and a lot of trivia romance
Sankarea surprised me with the art style. It was very surreal and cinematic and immediately reminded me of a Shaft show.
In both, the main hero meets girl(s) who has something to do with suppernatural. Both anime involve comedy and romance as well as fanservice.
