Cardcaptor Sakura, volume eight

Syaoran finally realizes that he's totes in love with Sakura, and Sakura herself takes on a giant teddy bear monster by growing wings and cutting its ear off with a sword, all while suffering from a fever, because she's badass like that. Aside from that, most of this volume was just setup for later stuff, like how Eriol, Yukito, and Sakura's dad all look alike apparently.
