Oh, I think I have some character sheets, it was one of the bonuses on the old Slayers DVD before Funi released them. I also think there were some in the Slayers RPG book I have. Although, it wouldn't surprise me if Diane already had them on her computer. ^_~

Did you just want the main cast? Lina, Gourry, Amelia, Xellos and Zel or were there a few others you wanted as well?
