After defeating a Behemoth almost entirely on his own, the King can’t just not acknowledge Ernesti, so he grants him and his gramps an audience to thank him and ask if there’s any reward he would like. Since Ernesti has the mind of an adult (and a mecha otaku to boot) he asks for the one thing only the King can grant: the secret to creating the Ether Reactor, the heart of a Silhouette Knight.
To everyone’s surprise, the king grants Eru’s wish, but first he must prove himself worthy of such knowledge by building everything around that Ether Reactor before learning how to build it. Eru accepts the challenge with relish, calling such work his “hobby” to the bemusement of all.
From there, Eru works with the Dwarf mechanics and engineers, knight Runners, and his friends and comrades to develop improvements to the Silhouette Knights, including a second set of arms to wield energy staves and a new kind of muscle construction that will make the knights stronger.
Things accelerate fast when he comes up with the design for a smaller “personal” mech he dubs Silhouette Gear, which Addy and Kid get the hang of almost too fast, eager to shoulder some of the burdens their friend is taking on.
Another who gets into the spirit of this inventive binge is Dietrich, who is determined to make amends for his cowardice, which Eru and others have kept largely a secret; now he’s working hard to be strong enough notto run away from a threat next time.
Helvi pilots the newly-redesigned SilKnight that Eru was instrumental in developing, in a suite of tests including a mock battle with the school’s Runner ace Edgar in an unmodified Knight. Helvi only loses because she runs out of mana, but it’s a great first step towards Eru’s goal of learning the secrets of the Ether Reactor.
Notably, there aren’t really any “threats” this week, nor even any technological setbacks that frustrate Eru or slow him down in any way. But trouble looms as there’s a mole within the development team feeding info to a seedier group of people. Eru didn’t really run into any significant problems this week, but it looks like that may change in the near future.
