Adaptations
The manga of the same name was created after the anime was developed, and while the major characters and plot elements remain the same, the overall story arc was (according to the production notes in the first volume) changed to fit the medium better, and a few new characters and subplots are added (i.e. Ochi, a manga only character, is a young landlady who is very taken with Sasshi that receives multiple incarnations throughout the different worlds. Also, Sasshi's feelings for Arumi are much stronger and less ambiguous than they are portrayed in the anime). Furthermore, the manga features more frontal nudity than the anime.
