Qoo Caloa

Qoo is a foreign girl who came to study at Kimisaki High around the same time as the Protagonist. Qoo loves sweets, so she often visits the cooking club to get some; she also practices making sweets on days when she doesn't have any lacrosse practice or competitions. Chiaki tends to be the one who cleans up her messes, while Qoo poses Hayate as her rival and often challenges her.
