Years have passed since Flio was summoned to the world of Klyrode, and quite a bit has changed since he first arrived. Over time, his house has grown from a small cottage where he lived alone with his wife Rys into a bustling community, complete with farmland and a mountain village. The Fli-o’-Rys General Store is now a mercantile giant, responsible for vital parts of the world’s infrastructure and economy. And his older children, Garyl and Elinàsze, have finally graduated from the Houghtow College of Magic, while the younger children in the house have just started attending school themselves. Their busy daily lives are interrupted, however, by a sudden increase in Beast of Disaster attacks that has the Celestial Plane itself reaching out for aid. What became of the legendary nine-headed Hydrana? Has Wyne met her match in another dragonewt? Will Garyl’s flock of admirers ever take a hint? And how worried should we be about Elinàsze’s worsening daddy complex?

The Maiden Queen of the Magic Kingdom of Klyrode reigns as a benevolent monarch during an age of peace, beloved by her people and acclaimed throughout the lands for her many achievements. Her Majesty, however, has a serious problem—one she shares with her strongest ally, the nigh-omnipotent merchant Flio of the Fli-o’-Rys General Store: a serious case of compulsive overwork! Flio’s wife, Rys, and the Queen’s sisters have all had enough of their respective loved ones burning the midnight oil with no end in sight. And so they come together for a common cause—Flio’s family and the Maiden Queen will go on vacation...together!

Banaza--now Flio for good--and Rys have managed to become a true happy couple despite being different species. Unfortunately, Flio's incredible cheat powers mean that he remains the most powerful piece on the board of this strange new world. Princess Elizabeth of Klyrode pays a visit to Flio to apologize for the cruelty with which her father's kingdom treated him, and to entice him into her web. Meanwhile, Gholl, the Big, Bad Dark One himself, faces a growing faction of demonkind that doesn't take too kindly to his ongoing association with Flio and other humans. Flio, with his unreal cheat powers, can change the course of the war and the fate of the world! Will he use his strength to destroy his enemies, or his essential kindness to bring peace to the world?

With his friend Ghozal in danger, Flio calls upon the forbidden time-manipulation magic he once used to save Rys. Even as a voice of warning calls out to him from the Celestial Plane, Flio makes the perhaps fatal decision to protect the peace he's built for his friends. But it's not all gloom and doom for Flio and Rys! At last, their mercantile dreams come true as the store opens for business--offering service with a smile to all, even as the conflict between humanity and demonkind grows ever more bitter. Could Flio's new store be the starting grounds for reconciliation? Will his extraordinary powers finally bring him the ordinary life he craves?

While living and working with the erstwhile Dark One Gholl, Flio finds hope that one day the deep rift between humanity and demonkind may be mended. But along with hope comes uncertainty as he grapples with the true extent of his magical power--and how to put it to use for the good of the world. But the disgraced former king of Klyrode has plans of his own. When the king-turned-kingpin's foxy new friends throw the economy into an uproar, Flio finds himself caught up in the calamity of commerce. Will he ever achieve the quiet, easygoing life he yearns for?

With a display of his prodigious power, Flio brings the conflict between humans and demons to an uneasy halt. At last, he can explore the possibility of peaceful coexistence between the two forces. Then Flio discovers that his time manipulation magic had a terrible cost: it cut off Wyne, the wyvern girl in his care, from her kin--forever! Rys and the rest of Flio's companions watch on as his regret drives him to desperation...Can Flio's friends help him bear the terrible burden of his incomprehensible abilities? If they can't, their whole world may be in danger!

Caught between warring humans and demons, Flio comes up with a new plan to spark communication between the factions--selling them both the secret to his magic! (With some strings attached.) Meanwhile, all is not well back at the homestead! Balirossa and company struggle with culture shock as they reckon with the newcomer Wyne the Wyvern and her decidedly inhuman takes on life and death. Flio's constant search for understanding leads to the snow-covered mountain homeland of the wyverns themselves, where he will walk a mile in their giant, scaly feet. Will hope prevail, or will the border wall of biases stand firm?

As hostilities escalate between humans and demons, Flio resolves to stay neutral. But Gholl, the Dark One himself, deposed by his brother Yuigarde in a coup, has other plans! He shows up on Flio's doorstep with his right hand Uliminas in tow. With so much world-shaking power gathered under one roof, there's only one thing to do: Road trip! The Kunosaki Hot Spring Resort may be just what Flio's motley crew of knights and demons needs. Is a little R&R enough to bring humanity and demonkind together? Or will Yuigarde and his minions pour cold water on Flio's vacation plans?

The ancient war between humans and demons is over thanks to Flio, the unassuming and omnipotent shopkeeper from another world, but peace hasn’t been an easy change for everyone. The end of hostilities between the Magical Kingdom of Klyrode and the Dark Army has left countless demons and magic beasts adrift, roaming the wilderness or selling their combat skills to unscrupulous villains. At least the Fli-o’-Rys General Store is always hiring! And with Flio’s newest invention, a gem that nullifies the toxic malicium lesser demons emit, true coexistence between humans and demons may yet be possible... Meanwhile, is Flio’s son Garyl ready for higher education? Does the Maiden Queen have a rival in love? And did Hero Gold-Hair remember to pick up his companion Wuha Gappoli after forgetting her in an inn during his adventure in the last book?

One day, after a busy afternoon of preventing the extra-dimensional Calamity Wyrm from destroying the world of Klyrode in its entirety, the nigh-omnipotent merchant Flio arrives home to find his housemates Balirossa, Uliminas, and Byleri bedridden with a mysterious affliction. Could it be an infectious disease? Did they eat something that disagreed with their stomachs? Or perhaps there’s another explanation for the three women’s sudden nausea and lembon cravings. Looks like Flio’s household is due for a handful of new members soon!
