Summary
I’m Kuhei Miyamaru (Miyamaru Kuhei), a salaryman stuck in a small-to-mid company. Every day, I’m forced to bow my head to the big corporations “higher up the food chain,” no matter what’s fair or what I can actually do.
Damn it…! The world’s rigged! It doesn’t matter how capable you are—once “status” gets involved, the pecking order snaps into place like it’s the only law that counts…!
Then one day, with all that stress eating me alive, I end up reincarnating into another world—one with swords and magic. And not as some random nobody, either.
I’m the third son of a ruler.
Heh… heh… heh…! In this life, I’ve got an unbeatable “position.” I learned the hard way in my previous life just how much status matters—so I’m going to use this sweet, privileged role to enjoy my new life to the fullest…!
…Or so I thought.
Before I can even settle in, my father and brothers die, and I’m forced to inherit the throne.
And the second the succession happens, a neighboring superpower starts making moves—schemes, pressure, the whole package! What, seriously? Even now I don’t get to stand on the winning side…?!
That’s when my “rare talent” (the kind Japan accidentally trains into you) catches the attention of a demon god’s servant—and I’m hit with a curse: if I don’t keep indulging in certain “adult activities,” my body won’t hold together.
The price is insane. The payoff is worse.
In exchange, I awaken power as a lust-tainted Demon King.
Wait—so to survive, I’m supposed to use this power to help resurrect the demon god, and keep getting dragged into increasingly twisted demands…?!
Fine. If that’s how it’s going to be, I’m done playing nice.
Anyone who looks down on my position—anyone who tries to shake my authority—I won’t forgive. I’ll build an absolute status here, no matter what it takes… and I’ll wield Demon King power to the fullest.
Arrogant troublemakers get captured and “taught a lesson.”
The HENTAI Demon King is born—into another world!
