Oh, we're definitely rivals, but it's no fun because he's always better than me :/ Except for the screenies in the winter of 2006! Oh I'll never forget that day! One day my great great grandson will laugh at Psy's great great granddaughter because of that, and then pull her pigtails. The story might change over the years.
I would also say that Yamaneko and vivi_lover666 are rivals.
