Splatter

Splatter takes place in the fictional city of Cumulus. The world they live in has 8 day weeks. 4 week months, and 13 month years (416 days a year). Despite having several known countries (Japan, France, Spain, etc.) mentioned, these countries don't actually exist in this world. The author merely uses them as a way to ensure that the things that are said make sense to the reader, as in when Felix is talking about "manage a trollie".
