Rocket and her friends Marco, Frank and his girlfriend attend a carnival to climb an old disused roller coaster. This has not been their first crazy stunt in search for adrenaline. After their climb, Rocket decides to hang around at the carnival and enjoy some of the less treacherous things the place has to offer. While roaming around the carnival Rocket meets a young girl called Sachi. At that moment she never thought that this wide-eyed girl with pink hair would lead her on such an unexpected adventure. However, Sachi is not quite as she appears, as Rocket would soon discover.
