Kraichhardt was reincarnated in another world with absurdly powerful abilities and rose all the way to become captain of the kingdom’s knights. Now hailed as humanity’s strongest hero, there seems to be nothing in the world capable of standing against him. But Kraichhardt never became a knight for fame, wealth, or even the sake of protecting humanity. He did it because he fell in love at first sight with the kingdom’s second princess, Marie, and desperately wants her to dominate him. As payment for defending the kingdom during wartime, Kraichhardt asks Marie for rather unusual “rewards.” There’s only one problem: Marie isn’t actually a sadist. She’s an ordinary, sensible princess desperately pretending to be the domineering mistress of Kraichhardt’s dreams because the kingdom cannot afford to lose its strongest warrior. And so Marie finds herself juggling matters of state, threats from the Empire, and the increasingly bizarre task of keeping humanity’s greatest hero satisfied enough to remain loyal to the kingdom. Meanwhile, the surrounding nations have noticed just how valuable Kraichhardt is. Powerful figures begin devising schemes to lure the invincible knight away from Marie, turning his peculiar desires into a matter of international politics. An isekai misunderstanding comedy about an overwhelmingly powerful reincarnated hero who thinks he has found the perfect princess to serve, and the perfectly ordinary princess frantically pretending to be his ideal mistress because her kingdom’s survival depends on keeping him happy.
