Cazanette

It was Nina's first time to go to an amusement park, thanks to her friends, Brix and Reevahn. While enjoying the park's attractions, they had an accident in "4D Travel Train". The train went out of rail. They were trapped until they found an exit - a different world, Cazanette. It is a mysterious world where once you're in, you can never get out. They encounter different species like talking horses and harpies. How can they get back to their world?
