Cardcaptor Sakura - Magical Mystery (Vol. 7)
As the plot of this popular series escalates, Kero notes that Sakura's  magical powers are increasing--and that she may need them in an upcoming  conflict. But other characters have special abilities. Sakura's older brother,  Toya, "sees things other people can't," and his vision causes him to follow a  mysterious spirit who takes the form of his sister. Sakura's substitute math  teacher, Ms. Mizuki, knew Toya when he was a junior high student and they  became very friendly--as Sakura discovers when the Return card carries her  into the past. Shaoran Li stretches his powers to call Sakura back, although  Kero suspects Yuki somehow aided him. Ms. Mizuki commands formidable powers  of her own, which enable her to smash the labyrinth erected by the Maze  Card--and causes Shaoran to fear her. Rated 13 and older, but appropriate for  children three to four years younger; minor cartoon violence.--Charles  Solomon
