Pablo's backstory gets a lot of coverage in the books about how awesome he once was, but aside from that, he tends to sit and mope a lot :S Although apparently, he does betray them at once point. It's part of the reason I would prefer Micchan to be Rafael, the gypsy, who at least gets to bitchy about everyone and sing songs by the campfire.

Incidentally, is it just me or does Yuuhi try and get away from the traditional flowers-and-chocolates-and-pink-pegasus endings as much as possible? She likes her heroic, tragic deaths for her character, while her Significant Other survives.
