Ace follows a voice and stumbles across an egg with a star shape on it; Lance attempts to stop a monster attacking the city.

Lance fights the Chaos Devil Dragon, but has a difficult time due to SDF's intervention; he special egg speaks to Ace, and Ace is able to create more Drops for Lance, leading to victory.

Tamazo, the special egg that hatched, gets kidnapped by the SDF; in order to rescue him, Ace and Charo sneak inside the SDF base.

Ace, Tamazo, and Charo safely arrive on Dragoza Island. When Ace visits his grandmother, she gives him a D-Gear, a device used by Dragon Callers; eager to try it out, Ace goes into the woods to find a monster that would become his ally.

Obtaining D-Gear and his first monster, Ouka, Ace wants to take the next step: getting his hands on a Soul Armor; Donny tells them that he can find one at the Sacred Temple, but warns that everyone who has set foot there have never returned.

Ace welcomes another monster, taking a step forward on his path to becoming a strong dragon caller; when he goes to stop a Drop Impact himself he may have bitten off more than he can chew.
