Shiina Tamai is an awkward, self-conscious teenager, struggling with school and self-esteem. But her daily travails become of secondary importance when she encounters and bonds with an extraterrestrial shape-shifting creature, one of a menagerie of spaceborn entities now on Earth, including terrifying Shadow Dragons, flying beasts of vast and lethal powers. And a new creature has emerged, an etheral flying "angel," but one whose wide, sparkling eyes and graceful wings mask even greater dangers -- which become painfully apparent to any who encounter her!
