All members of Maple Tree made it through the prelims and are joining forces in the eighth event's main round-a brutal three day survival mission. But they've all tamed monsters that perfectly fit their builds and they are unmatched in combat. They rampage across the perilous fields, annihilating bosses that slew countless other players and are well on their way to becoming a gauntlet that no force on earth can hope to survive!
