Seto Kamiki Jurai is also known as the Devil Princess of Jurai.  She is Ayeka and Sasami's grandmother.    She is the adopted mother of Noike Kamiki Jurai.  In her spare time, she likes to play matchmaker,  ~!including making Noike and Tenchi fiances!~.    According to Ayeka, Seto is even more powerful than the Jurian Emperor, Azusa.

Seina Yamada is unlucky... so unlucky that when he stumbles upon a recruiter looking for his senpai Tenchi he gets taken instead. Forced into the Galaxy Police, his luck begins to change. A natural to randomly jumping near pirates, he is assigned his own decoy to draw out pirates. His luck brings him into the lives of four women who have a habit of cancelling out his bad luck, turning it into good. Armed with this luck, they pilot the most powerful ships in the Tenchi Universe to defeat the Da Ruma pirates. Now the only uncertainty is whether the sexy Amane Kaunaq, a former model turned into a GP detective, sturdy Kiriko Masaki, who has known Seina for years, the mysterious Ryoko Balta, a former pirate named after the legendary one, or the child-like Neju Na Melmas, a powerful 2000 year-old priestess, will win Seina.

Continuing right where the last OVA series left off, the mysterious Lady Tokimi dispatches the warrior Z to Earth in order to learn more about Tenchi and his connection to Washu and Tsunami. Z is ordered not to lay a hand on Tenchi, but he may have his own agenda as he quickly sets about making trouble for our hero. Meanwhile, Tenchi's father and grandfather come to the decision that it may be time for Tenchi to learn even more about his past and his Jurian heritage. And the arrival of a couple of new female residents to the Masaki household threatens to upset the balance and inflame the rivalry over Tenchi's already decidedly divided affection.
