Just what was her role in the Tenchi in Tokyo series, other than being Tenchi's new girlfriend

She is the shadow of Yugi, but there was some other things but I havn't seen the show in a long time so I don't remember.

she was meant to drive Tenchi away. Tenchi was the glue that held the girls together and Sakuya was meant to 'distract' him and cause arguments between the other girls. It was Yugi's plan to separate the family. Why? I dunno. I forgot. I think she wanted to get revenge on the Jurai Royal Family for sealing her up for 3000+ years.

Wow that sucks

My least favorite character of my least favorite series of Tenchi Muyo. And if I recall it was actually quite a bit more than 3000 years. Poor thing was locked up since before Washu was born. Try 30k years.

she kinda looks like a guy o_O
