The war for the crown begins, and the two armies clash on the battlefield. While Rin, Lemia and Muller fight alongside the king's soldiers, Taichi and Aerial infiltrate Dortesheim's base camp to try and convince him to end the rebellion peacefully. But Inimicus, imbued with dark magic and drunk with devotion to Lady Shade, unleashes a spell which turns the soldiers of both sides into zombie-like berserkers who threaten to slaughter everyone in their path.
