Cels Forum

Ruri is the most popular character in the show, and her
cels are the most rarest and expensive in Japan.  I have
seen some average Ruri cels selling like 40000 yen (US$350)
over there.  The other female characters like Yurika are
expensive too, but not as much as Ruri.  The male characters
in the show are relatively cheap though.
Like Evangelion, Nadesico is sponsored by Sega which
they don't like their cels selling to the public.  Same
reason that you won't able to find that many Sakura Taisen
cels in the market.  Even if you find them, they're very
expensive.
