As León cannot properly control the flames of the Garo armor, Germán takes him to the Makai Alchemist Gael. Gael has been repairing the ring Zaruba which is part of his son's birthright as the Golden Knight. However, Gael’s apprentice Marcello kills the ageing Alchemist and steals the ring. He transforms into a Horror, and León, as the Golden Knight slays him and makes a contract with Zaruba. Meanwhile, Alfonso is attacked by Mendoza’s Horrors but is saved by a Makai Knight.
