Ernesti continues his work on the new mech: The Telestale. The new mech has serious design flaws, but even before things can be fully fixed, he's summoned by the Marquis Dixgard, a powerful lord with an interest in the young boy's work. Does he want the glory of designing the new weapon for himself?

With the Casadeus incident resolved, it's time for work on the Telestale to be completed. The nation's biggest mech design lab, the Silhoutte Knight Laboratory, is sent a copy so that they can attempt to make one of their own, and a tournament between the two will be held to see if Ernie's designs are as powerful as they seem.

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.
