A young genius programmer has a passion for building model robots. After dying in a car accident, he finds himself reincarnated in a world where robots are real, and he can pilot and build them!

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.

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!
