The city where Megumi lives is complex, high in crime, and a dangerous place where people often go missing. Guest often appears in an apartment in such a location. Megumi only speaks to Guest when he is lost or needs someone to listen. When Guest is speaking, it feels as though they appear either within Megumi's mind or as a physical hallucination.
