One month has passed since the Lyoko warriors have defeated the super virus, Xana. They thought their lives were finally getting back to normal, but Xana has returned in a way they've never expected. The gang has now become involved in a whole new adventure like no other with new allies to join in their battles against their longtime enemy.

Five years after the events of Chapter 1, the group thinks that everything is normal for them after defeating XANA. Are they right? (J/A U/Y O/S/S OC/OC W/?)
