I didn't know whether to put this under Yu-Gi-Oh! or original art. These characters are all made up, but they're duelists. The kid in the middle is named Madelyn, and she claims to be somehow related to Pegasus. The other two don't have names yet, but maybe you people could help me with that? I don't know that you'll see these guys much more, but maybe they'll turn up again someday... Black Rainbow is the name of their organization, by the way.
