While Jeanne engages the demons on the battlefield, Kevin tries to perform the ceremony and finds out that William rejects it for some reason. Appointed to guard William, Gilles de Rais goes to stop Kevin, but is deterred by Raguel. Gilles expresses his utter hatred and disgust of Heaven and its angels, as they were the ones that turned his "beloved Jeanne" into their pawn.

Despite being powerful, Solomon did not raise arms against his father and lived most of his life peacefully with his demon companions, much to Dantalion's bewilderment. After crushing his father's army that was sent to kill him, Solomon took over the kingdom of Israel. Although Solomon showed his father mercy, David refused to acknowledge him as his son and cursed him, much to Solomon's sadness. Soon after, Solomon requested to die by Dantalion's hands. Regaining consciousness, Dantalion saves Baalberith from being destroyed by Solomon and urges William to remember who he is to break Solomon's control. Lucifer awakens from his sleep and meets with Solomon, who then allows Dantalion to remove his ring to release his control over William. With Lucifer awake, the election for the interim ruler is halted and William is returned to the human world. However, William is distraught to learn that no one at the school, except for him (and Kevin), remembers Dantalion, Sytry, and Camio.
