Sakura, Kero, and the Mysterious Teacher
Sakura once again has the dream in which she is facing the Tokyo Tower. She clearly sees Ms. Mizuki, but this time, Mizuki is accompanied by another figure with long hair and wings. She wakes up early to see Yukito compete in an archery competition. She meets up with Syaoran and Tomoyo at the archery competition, and Kero tags along too. At the archery tournament, Sakura finds that Ms. Mizuki is one of the challengers and ends up in the finals alongside Yukito. During the fierce match, Kero pokes his head out of Sakura's bag upon sensing tremendous magical power, shooting a piercing glare at Ms. Mizuki.
