Hey gang! Having just watched OVA 4 episode 1, I made a few updates to the site. Specifically, I updated Section 1.2: Tenchi Muyo! Continuities to update the timeline. I also updated Section 2.3: TM!R OVA 4 to include new information.
Also, it is interesting that there appears to be a sequel to Pretty Sammy coming down the pipe. It certainly seems that the Tenchi cow is producing milk for AIC again. 🙂
