One day, her cousin Daiki asked her to participate in a virtual theme park's presentation by testing one of the new attractions, West Tower. Sakuya would like to go, but she has more interest in testing the other new attraction - East Tower, which is specifically designed for boys. At first, Daiki does not let her, but in the end he gives in when she expresses her strong desire. Unfortunately, an accident happens during the presentation and all the participants end up trapped in the virtual world. What actually happened? Can they find a way out? Things are not as simple as how they look.
