The title is a play on the Japanese title of Lewis Carroll's "Alice's Adventures in Wonderland" (不思議の国のアリス?) and the labyrinth is themed after the story, something that is discussed by the cast and used in some of the floor puzzles. Going along with the book motif, individual floors of You in Wonderland are called "Chapters", with the final floor being known as the "Epilogue". This labyrinth consists of four floors and introduces many key concepts of the game, such as the mapping system, blank cards, Power Spots, and F.O.E. The setting is inspired by Rei's memories of reading story books.
