If I knew it I'd do it, but right now All I've got in mind are the following:
K (anime) based RP - Perhaps parallel universe or something...
Digimon - not sure if I want it to involve Frontier(season 4) stuff or not...
Tokyo Ghoul - Maybe... Maybe not... See when I finish the anime...
SAO/Accel World type game rp thing - Meh... It's almost always on my mind...
