S1·E24 Time of Bloody Battles

With the four Dream Gods finally vanquished, Hypnos's divine barrier is lifted, and Athena's forces are free to march forward into Hades's Cathedral! Hakurei gives them a rousing speech posing as Sage, then enters the Cathedral alone to fulfill his deep-seated vengeance against Hypnos, who killed his comrades in the previous Holy War. Meanwhile, as Alone paints the Lost Canvas in the depths of the Dream World, Hypnos plays with his mind in order to turn him into the real King Hades.
