so my understanding about her is a lil mixed up, I'm not exactly sure of the relationship between her and kagato....I thought it was just that she fused with kagato at the end, but I've been hearing people talk about how she is a clone of naja, I'm not talking about kagato, i've been hearing people saying that NOIKE is a clone....and how exactly did clay get those cells in her anyway?

by the way I really dont understand why people hate her so much? she's clarity for tenchi when having to deal with ryoko aeka and mihoshi ganging up on him 24/7, and its not like she's hogging tenchi time. She lets all the girls get there time with tenchi, even mihoshi...so she's not bad in my opinion, just her character was a lil rushed, well all of ova 3 was, but overall i thought ova 3 wasnt that bad

This wikipedia page has as good explanation as I can give:
http://en.wikipedia.org/wiki/Noike_%28S ... miki_Jurai

I don't think Noike is a clone - she had met her mother in that one scene in OAV3. I don't know why she and Kagata are fused.

People seem to hate her because of:

a) They really liked Kiyone Makibi and instead of using her, Kajishima made his own, somewhat similiar creation
b) They think she treats Mihoshi like crap, all out of proportion to what Mihoshi does
c) They view her as another girl X, in a long line of girl Xes, swooping in to take Tenchi from the core group
and/or
d) They hate OAV3 and all that comes with it.

But Noike has a few fans of her own. They seem to like her because she brings order to the household.

People don't like Noike because she's new and different, and all that's different must be bad. Obviously.

People hate Noike, because, she was not needed. She stole the spotlight from Tenchi, and the rest of the girls.
And her personality was a mary-sueish version of Kiyone(Cop Kiyone, not crazy Tenchi Mom Kiyone).
She would be a bearably character if she did not hog the spotlight, but she's just everywhere. In the episode where Tenchi's sick, she just so happens to be a trained nurse, and when the goddesses turn back time, we see her appear at the end of the episode, sending Mihoshi's letter to Misao. So not only is she a cop, but she's a nurse, and also a timetraveler.

Sometimes feelings are just there and reasons are really just justifications.
