History Anime / TenchiMuyoRyoOhki

* HealingFactor: Ryoko easily grows another hand after Tenchi cuts it off.

* ForegoneConclusion: Anyone who has watched ''Anime/TenchiMuyoWarOnGeminar'' and ''Anime/TenchiMuyoGXP'' before this OVA will know that [[spoiler:Kenshi Masaki]] will survive the events of the later-produced fourth and fifth ''Ryo-Ohki'' series and ultimately be sent to Geminar, while [[spoiler:Tenchi Masaki and Seina Yamada]] will be in a relationship with their harems.

** Ryoko and Tenchi when Azaka and Kamidake capture and seal them up inside ''Ryu-Oh''.

** Tenchi at the beginning of the OVA when he encounters the Ryoko for the first time in the cave.
** Tenchi when Ryoko arrives at the roof of his school and is about to attack him.

** Part of Misao's plan to "rescue" Mihoshi.

* RakeTake: Subverted in the first episode when Ryoko steps on a metal rake in "Ryoko Resurrected". She doesn't get hit in the face, she instead bends the pole by smacking it. This, however, leaves an opening for Tenchi to slice her wrist off.

* HeroicBSOD: Ayeka goes into a brief depression after Tenchi tells her about Yosho's assumed demise and later when she sees the royal teardrop near Ryo-Ohki. Fortunately for Ayeka, Ryo-Ohki quickly snaps her out of it.

* MaamShock: Upon meeting Ryoko for the first time in the second half of in "Here Comes Ayeka!", Sasami refers to her an "older lady". Though initially frustrated, Ryoko shrugs it off and gives Sasami an AffectionateGestureToTheHead.

* OneCastMemberPerCover: The original OVA series did this with the first 5 volumes, with the addition of the character holding up a number of fingers matching the volume number. (#3 was a partial exception, as Sasami was holding TeamPet Ryo-Oh-Ki.)

* ForegoneConclusion: Anyone who has watched ''Anime/TenchiMuyoWarOnGeminar'' before this OVA will know that [[spoiler:Kenshi Masaki]] will survive the events of the fourth and fifth series and ultimately be sent to Geminar.

* TheMole: The [[VoluntaryShapeShifting shape-shifting robot]] [[MyHeroZero Zero]], who ends up [[BecomingTheMask merging with Ryoko]].

* PlanetSpaceship: The Kuramitsu family have a planet-sozed spaceship called that can destroy planets and seems to a nod to the Death Star from ''Franchise/StarWars''.

* WhaleEgg: Ryo-Ohki hatched from an egg that came out of Ryoko's crashed spaceship. When Sasami sees Ryoko with it, she thinks she laid it and Ryoko plays along pretending Tenchi is the father.

* ChekhovMIA: A ''very'' subtle example. In episode 4, Mihoshi's computer lists a few of Kagato's past crimes. If you pay attention to it as it fades into background noise, one of the crimes is the kidnapping of a "female student" from the Science Academy. Two episodes later, this turns out to be Washu (though of course she was actually a [[OlderThanTheyLook professor]])

* PhysicalGod: (Sasami/Tsunami, Washu, & Tokimi; also, [=OVA3=] spoiler:[[spoiler:Tenchi is revealed to be the earthly avatar of a being more powerful than the three goddesses who created the universe.]])

** Beginning with the third OVA, the main cast from ''Anime/TenchiMuyoGXP'' appears as major characters.

* WhaleEgg: Ryo-Ohki hatched from an egg that came out of a crashed spaceship. When Sasami sees Ryoko with it, she thinks she laid it and Ryoko plays along pretending Tenchi is the father.

* CastingGag: In the Italian dub, Misaki is voiced by Rosalinda Galli. This is not the first time she's played an alien before, as she previously played Lum in the Italian dub of ''Manga/UruseiYatsura''.

The first two ''Ryo-Ohki'' [=OVAs=] were notably the first anime produced and released by Creator/NBCUniversalEntertainmentJapan (back then known as Pioneer LDC).

* ForWantOfANail: If Katsuhito hadn't tricked Tenchi into snatching the key from him, Tenchi wouldn't have resurrected Ryoko, Ayeka and Sasami would've never encountered Tenchi, Mihoshi wouldn't have crash-landed on Earth and met the heroes, and Washu would've never been freed.
