Spring has sprung in Brunhild, and Mochizuki Touya continues to live his happy-go-lucky life. Flowers bloom, parties come and go, and everything seems just about fine... But wait! The mysterious pink-haired girl, Sakura, is identified by someone. Just what could this mean for her? Who exactly is Farnese Forneus, and what is her connection to the overlord of Xenoahs? But wait, a more pressing issue is the final piece of Babylon, and the remarkably twisted secret it has in store for our heroes... Set a very cautious course for a tale of swords, sorcery, and advanced cryogenics!

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!

16-year-old Mochizuki Touya has it all. Grand Duke of an upstart nation, inventor of goods ranging from hula hoop to caramelized popcorn, administrator of Babylon, and pilot of the Anti-Phrase Frame Gears. The western nations love him... but darker machinations unfurl in the far east. Yulong, the glorious Empire of Heaven, regards Touya with envious eyes, brazen enough to send assassins into Brunhild! To make matters worse, the mysterious young girl known as Sakura seems to have a connection with these dark assailants. In the background, dark forces gather. Something big approaches. Something far greater than anything Touya has ever faced before. Brace yourself... for a tale of swords, sorcery, and absolute calamity.

Undeterred by his untimely death on Earth, 15-year-old Mochizuki Touya continues to meander around in another world! After a series of misadventures, the young man has assembled a motley crew of adventurers including the timid mage Linze, the feisty brawler Elze, the ever-hungry samurai Yae, and even the young archer Yumina, heir to the Belfast throne. Together with his party (and a divine white tiger), Touya sets his sights on the horizon, heading for the demi-human kingdom of Mismede! But all is not what it seems... the beastman king issues a personal challenge, and a black-scaled dragon could soon spell out Touya's doom! The curtains lift once again on an epic tale of sorcery, smartphone apps, and... gunblades?!

 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 time has come at long last. Touya's set to get married to his nine blushing brides. The invites have been sent, the food is all accounted for, and the entire nation of Brunhild trembles with anticipation. But will he make it through the big day unscathed? Not if his divine retinue has anything to say about it! And of course, there's the small matter of his honeymoon... Bringing nine spouses through a spatial tear for a vacation on planet Earth sounds like a novel enough idea. What could possibly go wrong? Wedding bells ring, signaling a tale of swords, sorcery, and smiles!

The population of Brunhild is booming, which can mean only one thing. Guards, guards! We need more guards! A mass call is set out. "Knights Wanted: Apply Within!" But Touya might end up with more than he bargained for... Meanwhile, in the floating halls of Babylon, a certain resurrected doctor begins her mad machinations... Just what kind of crazy machine does she intend to build next? Set a chivalrous course for a tale of swords, sorcery, and burning sands!
