Tenchi Muyou!

Tenchi Masaki is a college student walking through the forest who sees what appears to be a meteor falling from the sky. He investigates and finds a beautiful young woman from the wreckage of a spaceship. Her name is Ryoko and she says she is being chased by a vicious criminal who later appears in the house, meaning to attack Tenchi and Ryoko. Meanwhile, a police officer of the galaxy, Mihoshi, attempts to arrest Ryoko for being a space pirate...

Princess Ayeka, first princess of planet Jurai, regrets responding to Mihoshi's distress beacon when she meets Ryoko on Earth. The two of them go back a long way, and have been enemies for years. During her time on Earth, Ayeka finds herself falling for Tenchi, and cannot endure Ryoko's shameless flirting with him.

The Masaki home is paid another visit by an interstellar traveller in the form of Sasami, Ayeka's younger sister, who has arrived to take her sibling back home. Meanwhile, Ryoko's wrecked spaceship gives birth to a cute replacement, and the mischievous space pirate teases Ayeka by telling her that Tenchi is the father!

Ryoko becomes a bit too curious about a mysterious cave near the Masaki shrine, and despite warnings of a legendary demon that sleeps within, she ventures inside dragging the unwilling Tenchi with her. They accidentally wake the demon and are chased from the cave. However, the "demon" turns out to be Washu, a mad scientist genius who was expelled from her academy 700 years previously.

Mihoshi's Galaxy Police partner Kiyone is ordered to find her missing colleague, and heads for her last known location. Kiyone is shocked to discover her supposedly deceased partner is alive and well and living with a space pirate, two Juraian princesses and a mad scientist.

Follow a day in the life of Mihoshi and Kiyone. The Galaxy Police duo are forced to find part-time jobs to pay the rent and bills on their new apartment. But with walking disaster Mihoshi around, holding down a job for even a single day proves difficult!

Sasami and Tenchi visit the annual shrine festival, but disaster ensues when the girls bring their own brand of mayhem and catastrophe to the stalls they are running, from monster fish on Ryoko's fish catching game to Washu's uncontrollable cotton candy machine!

Washu creates a robotic duplicate of herself to help out with her experiments. Unfortunately, an accident occurs when Washu's brain patterns are being transferred to the robot, and it ends up with Mihoshi's personality and intelligence instead!

A heavy snowfall brings back memories of Tenchi's childhood, and the day his mother died. Sasami has fun playing in the snow, but the cold weather doesn't agree with everyone. When Tenchi falls ill, a little help from Ayeka's life tree Ryu-Oh is needed to restore him to health.
