Cool, have Fun with watching the series!
It's my favourie anime and I Really Really like 
Elle :)

If you find it nice, the first (not the second) 
OVA is really nice too. Well, actually I really 
like the awesome fighting scenes in the ending 
part of the OVA.

Oops, sorry for digressing.... ;)

The character that you mention about in your 
post, the one with gold hoop thingie with Ppnk 
hair and wearing a green costume. Her name is 
Kyou.

--------------------------------------------------
Background on her: (optional reading) ;) Please 
scroll down for the rest of the message.

She's a septia, who is a demon beast catcher. Her 
grandpa died fighting a demon beast so she was 
like looking for someone to kill it to take 
revenge. As usual, she meets Elle, and blah, 
blah, blah, then Elle is helping her to kill the 
demon beast which she does successfully, of 
course :), and then somehow, you know, Kyou 
becomes a part of their team, which consists of 
Elle, Gau, Folli and Kyou.

End of Background info. :)
-------------------------------------------------

Actually, I am not really a fan of Kyou. I 
actually watch the show becuase of Elle mostly 
and some other characters. 

However, if you have cels of these characters 
from Shadow Skill, Please Please Please tell me! 

Cels:
( Shadow Skill )
Kooky or cute Elle 
Princess Lilivelt  
Dias Lag, who's Elle older and biological brother 
Almost any other characters, with the exception 
of Kyou and Gau, who's Elle little brother.

If you want pictures of them for identification, 
please tell me, I would gladly show them! :)
Although I don't know if it is possible to post 
them on this forum? 
Maybe I will post on a a temporary website or 
something till I finish making my webpage! :)

Thank You! for all the replies too! :)
