This is really confusing! There are so many seasons / arcs / OVAs that I don't know which one comes first, second, third...

Please help!

Hmmm... well, here's what I know of...

Tenchi Muyo! OVA (obvious)
Tenchi Universe (series)
Tenchi in Tokyo (series)
Tenchi Muyo Ryo-Ohki (OVA)
Tenchi GXP (series)

Aside from Muyo and Muyo Ryo-Ohki, the series aren't related, they're different tellings of the story. I haven't seen Ryo-Ohki but I assume it wraps up where the original Tenchi Muyo OVA left off...

Pretty sure there are movies, but I've never seen them.

Thank you so much! I've been wondering that for over a month!
