Son of Ryoko
It's the one when Mihoshi's brother is prosecuted.

Now i`m confused Mihoshi`s BROTHER?!? ..have i missed a tenchi series? i`ve never seen Mihoshi`s brother before (i`ve only watched the english dubbed dvd versions). Is this from the comic book version?

Minagi,
you mentioned Tokimi, as in lady Tokimi (from the tenchi ultimate edition dvd). Did lady tokimi ever get explained in the anim series, i`ve always wondered who she was. Again, i only saw her in the ultimate edition dvd and her character was left pretty unexplained, from what i remember. I do remember, when you see Tokimi appear in the episode 'zero ryoko', that you see what appears to be two large shadows behind her. One looks like a young Washu (which gives a hint to why she's after Washu in the episode). The other shadow doesn`t seem to look like any of the other characters in the series. I thought it looked like Kyone, who isn`t in that series. Or maybe Tsunami, but it didn`t look like her - from what i remember anyways.
