Succubus Above, Guard Below

As a transmigrator, Mr. Guard has always led the most ordinary life imaginable in this fantasy otherworld. That is, until one day, a succubus barges into his life. From then on, Mr. Guard encounters all kinds of prominent figures: a city lord who amasses wealth on a grand scale for reasons he cannot reveal; an evil succubus who covets Mr. Guard's soul and tries to make him her own; an old noble who appears generous and charitable but recklessly extends the reach of his wickedness; an elven slave who is both the greatest victim and the greatest perpetrator; magical girls who are supposed to be champions of justice but have long since strayed from the right path; a fellow transmigrator, a sweet and gentle Japanese guy who is devoted to creating an idol group in this otherworld; a wealthy merchant who holds compromising secrets about countless powerful people, despises true love more than anyone, yet longs for it more than anyone; a knight commander who committed an unforgivable crime, is consumed by guilt, and ultimately abandons his convictions; and more... Though caught in a maelstrom of desire, Mr. Guard is not alone. A man and a succubus try to see the true nature of desire in this utterly wretched world.
