Cosplay Convention means a good deal of ultra-cute looking femmes in ultra-cute looking suits of their dearest characters. But since this is also an escapade game then Cosplay Convention also will mean the battle against Evil Witch who has cursed all the cosplayers and now they all are under her possession. So it is truly good that you got to the place afterwards and your fucking accomplice had to wait for you near the entrance - now you are two peoplae who has not gotten under the spell of witch and now can fight back. But this fighting will be against other cosplayers plus it may be so severe that their costumes night end up being seriousle damaged... didn't we said that besides the escapade this game is also an erotic one? When you know it - have some fun!
