Anime / Tenchi Muyo! Ryo-Ohki
aka: Tenchi Muyo Ryo-Ohki

The original continuity of the Tenchi Muyo! franchise, consisting of three six-episode OVA series, one four-episode OVA series and two special episodes. The spinoff series Tenchi Muyo! GXP and Isekai no Seikishi Monogatari (a.k.a. Tenchi Muyo: War on Geminar) are a part of this continuity.

The first series, released from 1992-93, was mostly introductions to the major characters, who join Tenchi's harem via a Debut Queue. Episodes 5 and 6 bring in the first major villain, the space criminal Kagato. The second series, from 1994-1995, includes some major revelations about the characters' pasts and features a new villain, Dr. Clay. The third series, from 2004-2005 (yes, it took nine years to continue this story), focuses more on the characters' families and resolves some lingering issues from the first two parts. The forth 4-episode series began airing in November 2016 (yes, it took almost another eleven years to continue the story again).
