Rikka

Her true identity is that of an ace colonel serving in the Galactic Revolutionary Army. After her flying saucer crashed during a space battle, she found herself stranded on Earth, waiting for rescue. To conceal her alien origins, she employs a memory-manipulation device to pass herself off as an ordinary middle school girl. Despite her decorated career as a top pilot, she is remarkably clueless about everyday life on Earth, doing her best to keep her extraterrestrial secret hidden while sharing a lively school life with her friends.
