Guy with a 70-word vocabulary doodles on sleeping Naked Chick in a fit of sheer immaturity, Naked Chick wakes up and attacks Guy, Guy accidentally marries Naked Chick, and then the two gang up with Noisy Girl while trying to avoid Perverted Villain and his moronic minions. Meanwhile, Perverted Villain's fiancée, Naïve Princess, disobeys her father's word and goes off in search for her love. Got all that, or should I run it by you again?

Tenchi Masaki is a shy high school boy, yet honest and hard working. He looks forward to living a basic humble life, taking over his grandfather's shrine. However, nothing is ever as simple as one would want, as Tenchi soon learns. A series of events beginning with the sudden appearance of Ryoko, the space pirate, creates madness in his home. Now he must figure out how to juggle two princesses, a space pirate, two galaxy police, the world's most intelligent genius, and a rabbit-turned-spaceship in his quiet country home.

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!
