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!

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!

The concluding part of the dimension-travelling tale. The fourth mini-story follows a day in the life of a drastically altered Masaki family; Tenchi and Mihoshi are husband and wife, Sasami is their daughter and Ayeka is Mihoshi's bossy sister-in-law.

The fifth and final story finds Tenchi and Ryoko cast as American gangsters on the run from the law after committing dozens of daring robberies across the country. At last, Washu manages to re-establish control of the dimension tuner, but Ryoko is forced to choose between staying in her action-packed fantasy world and returning to reality.

Sasami is visited one night by a mysterious young girl named Mirei, who invites her back to her own ship to play. Mirei can create wonderful illusions with the wave of her hand, and she and Sasami have fun together in places from each others' memories. Meanwhile, the others, sick with worry over Sasami's disappearance, board Mirei's ship to search for her, but find the vessel has been deserted for hundreds of years.

The fugitives seek refuge amongst the ruins of the Juraian imperial villa, and finally discover the identity of the man claiming to be the rightful heir to the throne of Jurai; the exiled warrior Kagato. Kagato turns up at the ruins to face Tenchi's grandfather in combat once more.
