The episode opens with Ryoko demanded her gems be returned to her. Hearing, noise upstairs Noboyuki looks through Tenchi's cracked door. Seeing Tenchi with a girl he decides to video tape them (I told you he was a pervert).

Ryoko explains that another is coming who is worse than her. It is soon after that Ayeka, the Crown Princess of Jurai, arrives. Unable to locate her lost brother Yosho, she does the next best thing, finds Ryoko. Tenchi gives Ryoko one gem so that she can call Ryo-Ohki. Ryoko takes Tenchi, along with his shrunken house aboard Ryo-Ohki. However, she is soon captured by Ayeka and taken aboard her ship Ryu-Oh.

Aboard Ryu-Oh, Ayeka tries to force Ryoko to tell her where Yosho is but is unsuccessful (can't tell what you don't know). Tenchi wakes up in a cell and tries to escape; he is freed by Sasami, Ayeka's younger sister. She tells Tenchi she will return him to earth if he steal Ayeka's headpiece. Tenchi instead takes his sword which is known as the Master Key, which is able to control any Jurain ship regardless of the will of the true owner. Then he wakes Ayeka from her sleep and she order her guardians, Azaka and Kamidaki, to put him to death. While running with Sasami, Tenchi finds Ryoko and frees her using the Master Key. Ayeka returns just before Ryoko is able to take the other two gems. Again without realizing it, Tenchi uses the Master Key and enables him and Ryoko to escape on the Ryo-Ohki.
