As the Grizzly's Sin of Sloth laments of his failure to protect the ones he cared about, Helbram attempted to attack King from above while commenting that his old friend was always too late to save, reminding him of the destruction of the Fairy King's Forest and the abandonment of his country. This, however, provokes the Fairy King to viciously attack Helbram all-out. King use Guardian to grab hold of Helbram who the latter try to slice the Guardian. King dispel Guardian to form many blades to which attack Helbram and sent him flying down to a building. Helbram used Enchantment: Hard Protection to protect himself from King, but King once again sent Guardian to punch him out of the building. Recovering from such an assault, Helbram compliments of King's fighting ability to be a lot better than back at Byzel. 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.

Hauser try to fight along side King while protecting Diane, Helbram easily defeated him and set him flying to Diane along with Guila. Helbram used all of his Helbram summon his roots to ruthless kill Diane as King watch. As the smoke clear up, Diane was protected by King with Chastiefol barrier form as Helbram looked in shock as King used up all of his power to make the barrier.
