Isekai Tensei shitanode mazo dorei ni naru

"Here is your reward. Kneel down and lick my feet." (Wait, is this really the job of a princess!?)

Thanks to his reincarnation cheats, Kleichhart has become humanity's absolute strongest hero. However, Princess Marie—the royal who commands him—harbors a dark secret that must never see the light of day.

"I said it's a reward, didn't I? Now lick my boots."

As it turns out, the great hero is actually a massive masochist! To keep him in line, Marie is forced to secretly "discipline" him away from prying eyes!? Marie herself has absolutely zero interest in this kind of play, but Kleichhart's overwhelming power is essential to the kingdom's survival.

In order to secure the hero's unwavering loyalty, Marie must somehow juggle domestic political crises and the looming threat of the Empire, all while finding new, creative ways to "satisfy" him...!?
