When King orders Helbram to cast off his human guise so they'll fulfill the promise they made 700 years ago, he reluctantly complies and his true form was revealed as a fairy much to Guila's surprise. As King mentioned that he had no idea that Helbram would be at Byzel because of the worn-out helmet he was holding, an angry Helbram told him to shut up as he raised a giant root from the ground to attack King, only to be blocked much to his anger.

As both Fairies summon their weapons to battle, the fairies fought each other with their full power, while clashing their blade all around the area. As Helbram told King to give up, King deal with the final blow to Helbram, defeating him and breaking the Link orb.
