The BlazBlue OC crew and a few miscellaneous warriors are thrown into a sort of vast graveyard that seemingly stretches out forever. A voice echoes out to them: 

"Face those you have lost on the way of your journey, those you held dear. See the pain they hid away and face that pain head on. Let their pain be your strength to grow or join them in this eternal tomb"
