Tenchi Muyo!

from viz: the trouble and fun began when ordinary teenager tenchi masaki inadvertently released the legendary demon ryoko from his grandfather's shrine. turned out ryoko was actually a marooned space pirate! since then, she's become tenchi's unwanted houseguest, attracting a host of other troublemaking alien women: ayeka, a haughty alien pricess; sasami, her mischievous little sister; and washu, ryoko's mad-scientist “mother.” add ryo-oh-ki, an adorable little carrot-eating spaceship, and you've got one full shinto shrine!
