* BrokenBase: Fan reaction towards this series is mixed.
* DieForOurShip: Poor Sakuya.
** [[spoiler: AlasPoorScrappy]]: For some. Whether you liked her or not, it can't be disagreed that [[spoiler: having Yugi give her a BreakThemByTalking right before re-absorbing her by force (and when the poor kid is crying and begging Tenchi to help her!)]] was ''really'' cruel.
* EnsembleDarkhorse: Hotsuma
* GrowingTheBeard: The second half of the series, which actually features Tenchi growing a spine and telling the girls to leave him the hell alone.
* RecycledScript: The way the script ends, it could be called "An extended version of the Tsunami/Sasami" episode in the original series [[spoiler: With Yugi instead of Sasami one day becoming a romantic rival as well]]
* RelationshipSue: Subverted with Sakuya. [[spoiler:She's the shadow of the BigBad, and is just there to try to trap Tenchi. This means, she's a RelationshipSue and has to stay that way so the story works.]]
** [[spoiler: Sakuya's almost as vicious a [[DeconstructedTrope Deconstruction]] as [[KingdomHearts Xion]]. First, since every aspect of her personality tailor-made ''in-universe'' [[SatelliteCharacter to Tenchi's preferences]], she has some pretty glaring holes in her FakeMemories (and personal life, if her [[WhiteVoidRoom mostly-empty apartment]] is any indication). Second, despite being sentient, she ''doesn't exist'' and [[TomatoInTheMirror figures this out]] [[BreakTheCutie towards the end]], even becoming an UnPerson before [[KillTheCutie re-absorption]]. Her speech during her own heroic sacrifice can be summarized as "I enjoyed being your personal MarySue, but now [[DareToBeBadass you've got to leave me and save your other friends]] because they're real and I'm not."]]
*** For some, that [[spoiler:perfect and complete selfless attitude that seems to be bait to garner sympathy for the character]] makes her a [[PuritySue whole 'nother Sue]].
** QuirkyMinibossSquad member Hotsuma, who seduces Ryoko back to her life as a SpacePirate and away from her TrueCompanions, was frequently paired with her for "real" in {{fanfic}}.
* TheyWastedAPerfectlyGoodPlot: The series has elements of RomanticComedy and MonsterOfTheWeek, which led to a very forced-in plot, which would've been better either that the show tried to be more realistic and focus more on the relationships off Tenchi and his harem and have Sakuya being a normal girl [[spoiler: instead of the villain's conjured shadow made to keep Tenchi away from them]] and go into the depths of their feelings about the whole matter and led to a sound resolution; or focus on fighting spirits and limit the romantic themes significantly in order to present a very action packed story. Instead the story ends with [[RecycledScript another romantic rival for Tenchi with the very same reactions from the girls of Yugi growing up and becoming a threat to their confession of love]] and Tenchi returning to the chaos of the screwed up family in the Masaki shrine.
** Alternatively, it could've shown how Tenchi would been as a normal student instead of an insanely powerful hero.
** Also, the fact that this series is yet *another* AU storyline, rather than being a direct sequel to the previous Tenchi Universe series. It failed to capitalize on the previous TV series' blatant sequel hook ending, and the whole idea of the show (Tenchi deciding to move away from his crazy harem and go to school in the city; introducing a Muggle love interest outside of the Masaki harem...) feels like a sequel and deliberately plays off of the audiences' assumed familiarity with the characters and their relationships. Even the show itself seems to want to confuse the issue, what with its In Media Res opening episode, and not getting to the characters' origin stories until episode 7.
