Code:Sonic

When Odd, Jeremie, Aelita and Ulrich moved up to 10th grade and Yumi moved up to 11th, They befriended a new girl named Laci. She was dropped there in the beginning of the school year and soon learned of Lyoko. Laci, however, was a bit mysterious. During certain times of the day she would just disappear. After the first quarter of school ended, Principal Delmas invited Elizabeth's (Sissi) cousin, Richard (Richie), to join the academy and he sourly accepts. Having no friends, Richie is forced to hang out with Sissi, Herve and Nicholas. Richie soon gets fed up with Sissi's attitude and continuous harassment and tries to stay as far as possible from her. Walking around lonely, Laci becomes friends with him, which causes conflict with the Lyoko warriors and Sissi's gang. But that was the least of their worries.
