A Quick Note:

The stories that I have written are mine but I do not take any credit for the cc characters, but I do take credit for the cards and the new characters.

Prologue:
Although Sakura has caught all of the clow cards there are other clow cards. They are called the external clow cards. The cards are more based on emotions and such. They were released after Sakura released the clow cards. Sakura and Li don't know about them (well Li knows a bit about them but not a lot).
