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?!

Now that Touya’s got a party of four, he and his new friends are ready to take on requests! After buying some gear and picking up a few new null spells, Touya’s ready for anything that comes his way! But when a strange monster emerges from the site of their latest assignment, the team heads off to make a report to the duke… only to find that a crisis has broken out in their absence. Now it’s up to Touya to save the day, but time is not on his side…

Nefarious schemers have attempted to poison the king of Belfast and frame an innocent victim. Touya knows the truth, however, thanks to the abilities he gained upon being transported to this new world. But while his goal is to corner the culprit, Touya has something else to worry about—his helpfulness has attracted the attention of the king’s only daughter! Princess Yumina wants Touya’s hand in marriage, and she won’t take no for an answer…

After Touya declines a noble title for his service to the king, he receives a hefty sum of gold and amansion all to himself instead! But before he andthe girls can settle into their new home, they’ve got a new quest with international implications! They’ll have to open up a gate to Mismede-a deceptively simple task that doesn’t take long to go awry...

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!

Touya’s life is spiraling out of control, and the madness shows no sign of slowing down! One marriage proposal was enough to freak him out, but when several more come his way, he’s absolutely dumbfounded! Deciding which girl’s heart to break is an absolute no-go for Touya, but he may not have to choose after all…

Stalwart as ever, 16-year-old Mochizuki Touya heads off to the far eastern land of Eashen with his party in tow. For what purpose? The Matriarch of the Fairy Clan wishes to delve into some ancient ruins, of course! But it's never quite that simple for Touya and his friends, oh no. The party is thrust into the midst of a clash between the warlords Takeda Schingen and Tokugawa Ieyahsu, while a nefarious necromancer makes his move in the shadows... Throw in a Gynoid or two, an ancient legacy, another ridiculous summoning pact, and you've got yourself a brand new recipe for disaster! Once more the sun rises upon an epic tale of sorcery, smartphones, and floating cities!
