The new mechs are to be sent to Fort Casadeus, where the powerful Marquis Dixgard will take personal command over them. But on the way, a group of raiders lure demon beasts into attacking the convoy, hoping to steal them for their own.

A horde of shellcased, powerful demon beasts, are heading for Alfheim, the center of the nation's Silhouette Knight reactor design. If it falls, it will be impossible for any more Silhoutte Knights to be built. But if Ernie can save them, he'll finally get the ability to truly design his own mech from the ground up.

Ernie repels the Bronze Fang Ambush, but now the Jarodeks know where Eleonora is. Can Ernie hold off their levitate ships?

The Jarodeks launch a counterattack with a powerful flying wyvern mech. Ernie fights back, but his foe this time is far smarter than before, and has a new trap that can defeat even the Ikaruga!

After two draws, it's time for the final showdown against the Vyver! The capital city is almost at hand, and all that remains for the Western Grand STorm to come to a close is for Ernie to defeat the huge wyvern mech.
