In the series, parallel dimensions are accidentally created when the difference in a decision by a man on a construction site decides whether or not alien artifacts, including ships and giant mecha, are discovered or not.

This series introduces three new characters: Mihoshi's partner Kiyone Makibi (who debuted in the "Mihoshi Special"), the bounty hunter and Ryoko's rival, Nagi, and her cabbit companion, Ken-Ohki.
The series also gave some characters different personalities; Washu is now portrayed as a mildly-insane egomaniac with two pop-up dolls that proclaim her greatness, and Mihoshi was portrayed as a comic relief character whose constant bumbling, blunders and crying fits would often get the gang into trouble.

Tenchi in Tokyo (新・天地無用!, Shin Tenchi Muyō!) is a 26-episode anime series produced by AIC and Pioneer Animation (later Geneon Entertainment) and licensed in North America by FUNimation Entertainment. It is the third series (the OVA and Universe series being the first two) from the Tenchi Muyo! series.

Even though a lot of the characters return, most of them differ significantly from their original counter parts. Some of the differences stem from their clothing, to the settings, and personalities. Tenchi in Tokyo does have an original story, unlike Tenchi Universe which borrowed heavily from Tenchi Muyo! Ryo-Ohki OVA 1.

Sasami: Magical Girls Club[]
The members of the club
Sasami: Magical Girls Club, also known as Sasami: Mahou Shoujo Club (砂沙美☆魔法少女クラブ Sasami: Mahō Shōjo Kurabu?), is a magical girl anime which features the rather familiar likenesses of Sasami and other characters of the Tenchi Muyo! franchise, specifically those of Pretty Sammy. However, this series has nothing to do with either Pretty Sammy anime titles. The animation style is different and the anime itself is set in a very different alternate universe.
Produced by AIC and BeSTACK and officially recognized as a Tenchi Muyo! spin-off, it is aired in WOWOW on Thursday nights, the show aired its first season from April 13, 2006 to July 13, 2006.

Ai Tenchi Muyo[]

The series was directed by Tenchi Universe director Hiroshi Negishi, and the characters were designed by Suzuhito Yasuda.
The series seems to roughly adhere to the back story of Tenchi Universe. In the story, Washu's experiments have caused chaos in the world. For as yet unknown reasons, to solve it, Tenchi must go undercover as a student teacher at an all-girls school, with lots of trouble to follow. Many of the new characters follow the archetypes of the characters in the Japanese fairy tale Momotaro.
Hitoshi Okuda manga[]
No Need for Tenchi! and The All-New Tenchi Muyo! are the two spin off manga written by Hitoshi Okuda. Although split into two series, they are one story (The change in name occurred when the monthly publication of the series was moved to another magazine). The manga is based on Tenchi Muyo OVA 1 and 2, but it veers from the original continuity to tell its own story.
The first series ran for 12 volumes, from December 16, 1994 to June 9, 2000, and the second from July 26, 2000, to December 9, 2005.
Another volume, not specifically tied to either series, was published as Sasami Stories in the United States; it contained republished chapters from No Need For Tenchi, featuring Sasami, and also a collection of Okuda's 4-koma (four panel) comic strips called Tenchi, Heaven Forbid! G... that featured "commentary about the strips in the form of an ongoing conversation between Okuda and Sasami.
One interesting fact is that this manga often breaks the 4th wall, with the characters sometimes making comments about how certain characters appeared in certain volumes or chapters, and similar.
