A creature materializes in your closet and becomes your secret. That's the entire premise, and the show commits to it like a real friendship, messy, weird, protective of something nobody else understands. For 200 episodes, it never breaks the spell of that first inexplicable moment, the one where magic stops being a concept and starts being the person sitting across from you.

A young boy opens his closet and discovers a strange creature holding a parasol sitting inside. No one knows how the visitor arrived or what mysterious world he comes from, but the two become close friends right away, and their friendship is something no one else can ever learn about. What follows is a long-running comedy adventure with a fantasy twist, built around an impossible friendship between an ordinary boy and a peculiar guest from a fairy tale.
