So I hear there has been some confusion about the correct order of the several Tenchi series. So allow me to explain.

The first series created was the original 3 Tenchi Muyo! OVAs. It is also known as Tenchi Muyo! Ryo-Ohki. It has 20 episodes and has been aired on Toonami several times. In this OVA, Tenchi has special powers, unlike the 秒 series.

-The first OVA is episodes 1-6.
-Tenchi Muyo! Daughter of Darkness*
-Episode 7 is a special.
-Episodes 8-13 are OVA 2. (Including the bonus episode 13.5)
-Episodes 14-19 are OVA 3.
-Episode 20 is a special.


*The movie Tenchi Muyo! Daughter of Darkness...
