Jack Thorn was transferred into a new fantasy world, lived in it and fought for the king's orders for a few years, ending dungeons and demon lords ― and has just in the last year been forced out of the capital. Finding residence in a small village on the outskirts of said kingdom, he found a young woman who became his companion and wife; but she also has a secret of her own. He thought her at first just a mundane demihuman or part demon race, from her physical features different to the humans he's seen.

Rose is a young woman, formerly a pretty young latina, who is also just new to this world; but worse: she is now a dungeon mistress of a small dungeon on the outskirts of a warlike kingdom. She hid the inhuman part of her existence ― in part by walking among the mostly human villagers and observing. Each day she awoke in those first days, she trembled in fear of how some "hero" (a human like she once was) would come and ... end her dungeon, end her minions ... end her. Until, the day she met, and rescued, Jack.

Plus now, someone in the kingdom got word of the fact, [i]there is a dungeon near this village[/i]. She's sure it isn't her lover Jack who told; but then who? Regardless. The kingdom has sent this Inquisitor to inspect how 'dangerous' she is, as a dungeon ... by questioning not her, but Jack.

Together, as Jack and Rose Thorn, their lives are closer to complete ... or at least, less broken, with minor quibbles here or there. Rose does want children; Jack is afraid of what will come of them. Jack wants to set up a shop near the village or a cabin too; Rose is afraid of never seeing her beloved again.

And the villagers, well ... some of them know something strange is afoot, and are about to go looking for the cause.
