* SugarWiki/AwesomeMusic: In true ''Anime/TenchiMuyo'' fashion. [[https://www.youtube.com/watch?v=lBtvlXeYeyM The opening theme to the original OVAs]] is particularly good.
* BigLippedAlligatorMoment: Pixy Misa's VillainSong in episode three of ''Magical Project S''. It comes out of nowhere and has zero relevance to the plot of the episode. It's completely forgotten about immediately after.
* EveryoneIsJesusInPurgatory: The exact nature of Pixy Misa is still open to speculation.
%%* IronWoobie: Misao.
%%*{{Moe}}: Sasami.
* QuestionableCasting: Sue Turner-Cray as Misao in Episode 1 of the dub. She practically whispered her entire performance in a failed attempt to sound like a child, and clearly had great difficulty hiding her British accent. Her French accent as Pixie Misa is also questionable. When Creator/DebiDerryberry took over for the second episode, nobody complained.
* {{Squick}}: The OVA features the very questionable visual of Sasami (explicitly stated to be 10 years old) being completely naked during her transformation sequences.
* TearJerker: Tenchi's one appearance in the TV series ends with him not only having to leave, but turning out to have a girlfriend. In the face of both of these revelations, all [[PrecociousCrush Sasami]] can do is break down crying in Misao's arms.
%%** The ''death'' of Makoto.
%%* ToyShip: Sasami and Ryo-Ohki, Rumiya and Misao
%%* TheWoobie: Many of children characters have there moments, specially Sasami and Rumiya.
