The Black Bulls get a sudden visit from Mereleona and she drags them to the strong magic region of the Yultim Volcano. There, the Crimson Lion Kings, as well as their captain, Fuegoleon, and his younger brother Leopold, were waiting for them.

Finding new resolve, Magna, Luck, Charmy, Gordon, and Nero all decide to train in the fiery underground cave of the volcano!
