Sakura and the Mysterious Transfer Student

S3, E1: We got back from summer vacation to discover that we had a new student in the class! His name is Eriol Hiiragizawa and he came here from England, but Sakura thought she had met him before. That night, Kero and Sakura were talking about Eriol's arrival when they felt a strange presence. We all went to Penguin Park in the rain to check it out, but a big stream of water attacked Sakura! When she tried to stop it, she realized that her magic wasn't working!
