It tells the story of the confrontation between four students of Kaide College (Cadic University): Remy (), Qi (Chen Di), ulrich (Ricky) and Mei (Zi) and the evil artificial intelligence program XANA (carolina in summer). Remicade College was discovered in a mysterious supercomputer far away from the abandoned factory. After Curiosity opened the mysterious supercomputer, a program named Leo (Ranco) ran on the computer, and a mysterious girl and the discovery of the virtual world were discovered in the virtual world. Remy named her Maya, Maya's round tower. Later she learned that his name was Aleida (Dong Meiwa). When the supercomputer was turned on, a strange event called Kaide College appeared. Remy also ran an artificial intelligence program in Leo-XANA (Carolina in summer). Its purpose is to escape and control the supercomputers in the world. The solution is to destroy the computer and shut it down forever, but it will disappear Aleida, Remy. He hoped that road would come to Alejandro, and Remy tried to find a way to attack the earth during this time. Various threats to human life have occurred. When it happened, Remy met a classmate, Odd, and ulrich and ulrich met May in the gym. They refused to attack XANA. In order to prevent XANA from threatening the earth, Alejandro had to enter by XANA and started the round tower. Leo created many monsters (attack programs) in XANA to stop Aleida, Curiosity, Beauty and ulrich from being on the round tower, then digitized them, and input Leo through the scanner to help Aleida destroy the monsters. Remy's computer operation in the real world provides Leo with various tactical information. After successful locking, Round Tower and Remy began to rush back to have time to return to the program state before XANA attack, but only when there were no casualties, the time reversal process would not wake people up.
