Tenchi, Ayeka, and Sasami are outside admiring Ryu-Oh, Ayeka's spaceship, growth. Tenchi leaves for school and Ryoko sees him off. At Kiyone and Mihoshi's apartment they are getting packed. Kiyone has gotten a promotion and is returning to Galaxy Police headquarters. When Mihoshi finds out that she's not going too she's devastated. While Kiyone and Mihoshi are at Tenchi's house.

Kiyone is saying goodbye to everyone. Tenchi is on his way back from school when a Jurain battle cruiser flies overhead. When he gets home... its not there. Only Ryo-Ohki is there and is telling him what happened. Unfortunately he doesn't speak cabbit. Tenchi's grandfather shows up and a crystal falls from the sky. It opens up and Washu, Kiyone, Noboyuki, and Mihoshi fall out. Washu tells Tenchi what happened. The battleship transported them all aboard. Ayeka, Sasami, and Ryoko (Because she couldn't keep her mouth shut) were arrested. The Azaka, Kamidake, and the house were shrunk down to a more portable size.

They all go off in Yagami, Mihoshi and Kiyone's ship, to save their friends. On the ship somebody named Emperor Yosho has ordered the arrest of Ayeka and Sasami. Using one of Washu's inventions, the Inter-dimensional Door, they sneak aboard the Jurain ship. They need to be within 800 meters in order to use the door. You see the door doesn't work like it would in a cartoon. After a few skirmishes they find the prison and in order to break them out they change Ryo-Ohki into a spaceship which bursts out of the ship and everyone gets away.
