I think there are only Tenchi characters in the 
Pretty Sammy spoofs. Jinnai is from El Hazard, so 
I don't think he makes an appearance. I could be 
wrong, however - aren't both of them AIC shows? 
In that case it's always possible they had him as 
a cameo. Just last night I caught Sasami in the 
background of a crowd scene in Hyper Police ^_^  
and I know that Mr. Fujisawa from El Hazard made 
a background cameo appearance in. . . I think it 
was an episode of Tenchi in Tokyo. I can't 
remember.

But you really have to rent the second Pretty 
Sammi that spoofs Microsoft and Bill Gates. My 
husband and I died laughing. ^_^
