Shaoran y Meiling vuelven a Japón para darle una sorpresa a Sakura que ahora tendrá que capturar a la carta desconocida y declararle su amor a Li.

Summer holiday is over. Nora begins sixth grade and is drawn to intrigues and doesn't really know what side she's on. Or wants to be on. On one hand she feels sorry for the bullied Karin, one the other hand she wants to be friends with tough Fanny and Sabina.

Sixth-graders have many things on their minds. But they are confronted with an important decision: do they continue their education in secondary school A, B, or C, or do they go to grammar school after all? And what even are those things? How do children deal with the hopes and fears associated with this step?
