Nearly every series has a primary character who is
disproportionately priced, for whatever reason.  ^_^

For Slayers, it's Xelloss.  Why does he
cost so much more than the other main characters?
 Because he doesn't show up in as many episodes,
and because the fans adore him.  For Bakuretsu
Hunters, it's Marron, for being bishy and
badass.  For Rayearth, it's Eagle.  Nuriko
is just, as they say, par for the course.

A pretty, strong, gay, funny, loyal, likeable, and
deceased par for the course.
