Despite this, she finds solace in her two partners: the independent and reliable Kumi Kawamura, and the smart and energetic Kasumi Tomine. As the Alien Party works to fend off extraterrestrial threats, will their roller blades and lacrosse sticks be enough to overcome the dire challenges ahead, or will they succumb to fear and suffer the grim consequences of defeat?
