Doctor Babylon creates a new technological breakthrough thanks to the help of Elluka, a renowned Gollem engineer. What is this new invention, you might ask? Why, it's the Core Frame, of course! A new, revolutionary animal-shaped mech that interfaces with the Gollems of the Reverse World. But will they be able to iron out all the kinks before disaster strikes? The golden mutants stand poised to bring the Reverse World to ruin, and they won't wait around for countermeasures to be perfected! Brace yourself for a tale of swords, sorcery, and political powerplays!

Still struggling to unite two worlds, fledgling god Mochizuki Touya carries on with his work. The mutants continue to attack the Reverse World, hungrily devouring the souls of the fallen in service of Yula and the wicked god. And so, it's up to Touya to teach another set of off-worlders how to pilot the Frame Gears! Hopefully he's not too late... Elsewhere, a mystery unfurls regarding a long-lost prince of a devastated kingdom... Perhaps the Mage-King of Isengard has the answers Touya seeks? Chaos runs rampant, tearing open the veil upon a story of swords, sorcery, and heterochromia!

The time has come for the showdown against the wicked god. There’s just one problem... Touya and company need to purify the venom surrounding Isengard first! But fret not, Uncle Kousuke is here to help. He just needs a little assistance nurturing a very special sapling. Meanwhile, Touya thinks back to Earth and finds his thoughts returning to the family he left behind. The final battle begins at last, ringing in a story of swords, sorcery, and very unhelpful Unicorns.

 It's time for the Duchy of Brunhild to host a national festival, and Mochizuki Touya is smack-bang in the middle. World leaders are in attendance, nobility, traveling adventurers... And even God himself has seen fit to grace the mortal realm with his presence. What will Touya do when the big man upstairs comes downstairs for a change? More importantly, will he have enough dessert?! Meanwhile, in the Reverse World, tragedy strikes... An unusual purple Gollem surfaces alongside a strange, depraved woman... Their actions paint an otherwise calm marketplace deep crimson... Put on your party hats for a tale of swords, sorcery, and tasty snacks!

The two continents have finally collided, but the dawn of this new world is quickly overcast by a sinister bombardment from the space between worlds. What foul machinations has the wicked god orchestrated? Touya may not live to find out! The unstoppable Grand Duke of Brunhild has finally met his match in the form of a poison that can render he and everyone he loves completely powerless! Pack your antidotes and prepare for a tale of swords, sorcery, and drones!

The Duchy of Brunhild is abuzz with confusion as a great airship appears in the sky, bringing with it a group of curious Gollem engineers! But what do these mysterious Seekers want with Yumina's white crown? And just what secrets lurk within the ancient ruins of Gandhilis? More importantly, will Yakumo ever come home? Hold fast for a tale of swords, sorcery, and mechanical marvels!

Mochizuki Touya has no time to rest. The fate of two worlds hang in the balance, after all. The Metal Devils, guided by Yula and seemingly supported by two mysterious twins, are on the rampage... They've mercilessly targeted the souls of people in both the world Touya knows, and the Reverse World! Armed with his new Frame Gear, Reginleif, will Touya be able to stop the malignant machinations of a wicked god? Fissures in space begin to crack, revealing a story of swords, sorcery, and a corrupted knight!
