In the year 2999: humanity is split into two factions, Terra and Ness, in a war fought by starships. One of the foremost of the pilots is the cocky teenager Yamamoto Yohko, and during one of her missions, she and her crew are sucked into a temporal anomaly (a la Star Trek) that sends her back to our time. Amnesiac, she only thinks of herself as a typical high school student - until a course of events sends her back to her ship the TA-29, with her newfound friends fighting at her side in a war that looks suspiciously like an arcade game (complete with 100 yen ignition costs!).

Tenchi runs off into the woods to spend some time alone after his friends have another argument. While lost in thought, he hears a voice coming from a camellia tree. Tenshi approaches it and vanishes through a portal. Six months later, Tenchi still has not returned home. Though most have given up the idea of ever finding him, his friends refuse to lose hope and have split up into two teams. Aeka and Ryoukou remain on Earth to investigate while Washuu, Sasami, Kiyone, and Mihoshi comb the rest of the galaxy in search. Their efforts eventually pay off when Tenchi's energy is picked up on their radar. However, the happy reunion will have to wait as the girls gear up for their biggest challenge yet—Tenchi seems to have completely forgotten them and is living happily with another woman. Instead of solving their problems, finding Tenchi has left them with even more questions. [Written by MAL Rewrite]
