Upon arriving in Shio Island, Momoko discovers an old box in the attic containing a book of drawings of monsters. From then on, she starts noticing a series of mysterious occurrences around her. "There must be something on Shio Island," Momoko thinks, and in the strange and lively summer of Shio Island, she encounters something unexpected... This film is produced by the renowned Japanese animation company Production I.G and is a heartwarming and healing work by director Keishi Ochi, who directed "The Werewolf," after a long hiatus.
