* Based on Neko no Danshaku (The Cat Baron) by Hiiragi Aoi. Haru is a clueless, ordinary 17-year-old girl. Neither has she any special abilities and nor is she an extraordinary beauty. When faced with reality, she is unable to make decisions for herself, thus often swaying to others' opinions to avoid a challenge. One day, Haru saved the life of a cat without consideration for her own safety. The cat turned out to be the Cat Prince from the Kingdom of Cats, however as a result, Haru is trapped in the world of cats. Can Baron and Muta rescue Haru who has wandered in the world of cats? Note: This movie is somehow related to Whisper of the Heart, it follows Muta and Baron (the cat and the cat statue in Whisper of the Heart, also used in Shizuku's story).
