Tenchi Masaki is a normal high school student in Japan, who spends the summers doing chores around his grandfather's family shrine. One day, Tenchi manages to steal the key to a mysterious cave where an oni (Japanese demon) is said to have been sealed away by his ancester Yoshou, whose sword still stands guard over it. When he enters this cave, he finds that, much to his surprise, the legend is indeed true when the oni's dessicated skeletal form ("mira"--Japanese mummy) comes to life and attacks him. Tenchi flees the cave in a panic, and later returns to high school, taking the hilt--seemingly all that remains of the ancestral sword--with him. At school, Tenchi is again attacked by the oni, whose name is Ryouko, who has now completely revived herself. Tenchi manages to defeat her with the sword's help, but this is only the beginning of a hilarious Japanese romantic comedy OAV (Original Animation Video, the Japanese equivalent of American made-for-video movies) series which has spawned...

Did You Know?


When Tenchi catches Ryoko during her battle with Kagato in episode 6, he tells her "I still have feet". This was Tenchi's way of reassuring Ryoko that he's not dead. In Japanese folklore, ghosts are typically portrayed as legless. See more »


In Tenchi Muyo OVA 3 (which it was made around 2000) the sound effects, when you set your DVD language to Japanese, doesn't match the motions of the character at all. In the English one it does match. See more »


Ayeka and Mihoshi: Hi, Tenchi!
[they walk towards him, but Ryoko trips them]
Ryoko: Hee hee! Too bad! I'm going to be the first person to give Tenchi a hug!
[she sees Ryo-oki on Tenchi. Ryoko falls]
Ryo-Ohki: Meaow! Meow!
[Ryoko snatches Ryo-oki]
Ryoko: I said I'm first!
Washu Hakubi: Nice to meet you. My name is Washu. I would like to thank you for saving me from Kagato.
Tenchi Masaki: Oh... uh...
Washu Hakubi: I like you. You wanna be a guinea pig for my experiment?

Extremely pleasant surprise.
17 August 1999 | by (Brampton, Ont.) – See all my reviews

This will put the kid back in you. One heck of a mini-series surrounding the world of a boy and a couple of alien females who not only fall for him but hate each each other's guts. Then trouble comes in the form of one flipped out (but always smiling) villain. This is japanimation at its finest and I thank my friend very much for introducing me to this fine mini-series. There is no reason to hate or get sick of any of the characters (especially Sasami) because they interact so well in their own environment. One STRONG recommendation: if you understand Japanese, I suggest you watch that version. Other than that: All hail Ryo-Ohki!!! Myaa! Myaa!
