Joanna is your typical American blondie teen, a close friend to Kiana. Her athletic skills really maxed out in basketball, thus she joined The 'Rock You' junior basketball team & positioned as Small Forward because she's more agile than her teammates/friends. However, no one but coach Soujiro knows that she hid her bitter past behind her cheerful smile. But after a few (bed) encounters with Soujiro, she opened her heart & became a more sincerely cheerful girl, err, woman.
