Madoushi
Antagonist of the first Cardcaptor Sakura movie. Was a water fortune teller whose business was put under by Clow Reed's more accurate fortunes. She challenged Reed to many fights, but never resolved her conflict with him. When she died, she bound her soul to a book and remained alive inside of it for centuries waiting for her chance to see Reed again.
As it turns out, she isn't waiting for a chance to kill Reed, but is actually in love with him.
