Somehow, it crashed on Earth and was buried, until an earthquake broke it open 3,500 years later. The reason for this was that, in fact, she was the last heir to the Balta Guild, which stands to become a member of the Galactic Union. She had briefly resumed her form as Washu-kami-sama when Z had threatened the universe by battling Tenchi. Tenchi runs off in search of her, but cannot find a trace of her anywhere. officer, Kiriko has access to much of the G.P. Aloof yet down to earth, she balances the household and dispels most of the chaos. Kagato is initially surprised, as the power from Tsunami that allows Light-Hawk-Wings to be created has been cut off from the rest of the universe, but he quickly realises that these Wings come from within Tenchi himself and do not rely on any connection to Tsunami. With their master sealed within Bizen as part of a gambit to bend its will to her own, it falls them to act as her proxies in order to collect the secrets needed to complete her plan.A pair of space pirates who confront the Masaki household during an interstellar treasure hunt. Tenchi stands to shield Gohgei from a final attack, and on seeing the heir to Jurai Hishima recalls one like him through Hishima - Katsuhito. Boastful, Seiryō thinks it would be a wise idea for Tenchi to concede – not wanting to "bully the weak" – and beseeches him not to worry as he won't be using his full power. Tome, the second cook of the restaurant, goes to Sasami with a request; throw the match, as Kazuma might be used as a puppet by his dad for the rest of his life otherwise. Either way, Seina has shown tremendous concern and affection for Neju which she seems to reciprocate to a certain degree. It was only after seeing Amane's skill and abilities during a live-fire demonstration of the latest G.P. As opposed to our own three-dimensional space, there are 22 spatial and temporal dimensions commonly known to exist within the Tenchi Muyo! During a brief stopover on Earth, the Kamidake II crew was surprised that Neju had showed up at Seina's new home (built from the interest accrued from an account of his pay and sent to his family). Though Ryōko was still annoyed by Tama's attempts to steal her food, she no longer objected to the girl's presence. Mashisu, as well as Misao, were surprised to find that the 'explosion' was actually a transport beam, and Mashisu was embarrassed that everyone had heard them and her confession to Misao. However, she only resorts to physical aggression with Ryoko, and even these fights have diminished over time.
She was kicked out a month later for developing a weapon capable of destroying the entire universe (though as Tenchi narrates, no one was surprised). His partner has substantially better luck: Mikamo cloaks itself as Mikamo grows increasingly enraged as he fires repeatedly from orbit, his attempts at reprisal blocked by Tenchi and his Light-Hawk Wings.
When Washu first appears, she critiques her daughter's sex appeal and asks Ryoko to refer to her as "mommy". As a result, the four are included into the marriage as well as the crew of the Kamidake.
In OAV 3 (episodes 14-20), she seems to have taken on a few of the characteristics from the other series; she becomes less competent, and appears more confused than usual (though this may simply be a result of her, and much of the regular cast, having less screen time than in the other OVA episodes). At the end of the series, after being promoted to the GP's high ranks, Kiyone returns to earth for reasons unknown. Still, after being kidnapped by Kagato and released by Tenchi, she returns to Jurai because she must remain with the Imperial Family from then on; but as the series concludes, Ayeka chooses to run away from home and rejoin Tenchi on Earth.
The two of them made a bet long ago that would result in the loser becoming a slave to the winner...with the nature of the bet being whether Yume could use her scientific genius to conquer Jurai.
