Japari Park is a wild paradise where numerous humanoid animals, called "Friends," go about their daily lives throughout the natural environmental park. On a lazy afternoon in the savannah zone, the energetic Serval comes across a strange new Friend. Out of curiosity, she quickly tackles the newcomer, named Kaban, in an attempt to figure out her species. To Serval's letdown, Kaban herself has no idea. The pair become friends and embark on a grand adventure across the various habitats, landmarks, and attractions of Japari Park. They aim for the park library, hoping to clarify Kaban’s identity. Along the journey, they encounter many other Friends, observing their lives and lending a hand. Yet, they gradually start to reveal the sinister truth behind the park and their own existence.
