Dandadan is a wild, genre-bending manga (and now anime) by Yukinobu Tatsu. It follows high schoolers Momo, who believes in ghosts, and Okarun, who believes in aliens. Their conflicting beliefs lead them to supernatural encounters, forcing them to team up against bizarre yokai and extraterrestrials. It's a chaotic blend of action, comedy, sci-fi, and budding romance.
