looking for untranslated spooky children's manga

[zombtron]

so i figured it would be a good idea to start translating manga to help me with my japanese study, but it seems the H doujinshi i started translating turned out to be a little above my comprehension level (slang and whatnot) so i figured i should start with something easier like children's manga, problem being i don't know any, id perfer something with monsters, ghosts, or yokai to help keep my attention, but ya know whatever suggestions y'all might have would be great
