A man, who continued his training believing in the legend that one could become a Demon Lord by refraining from relations with women for four centuries, finally acquired immense magical power and tremendous strength worthy of the title Demon Lord.

To fulfill his childhood dreams—"to become a person of standing," "to marry a beautiful bride," and "to become a respectable father"—the Demon Lord embarks on world domination with his overwhelming power.

However, while his first dream was smoothly realized, he encountered a massive obstacle when attempting to fulfill his second dream.

The Demon Lord, who disdains marrying by force, yearns for a wife who will genuinely love him; yet, having secluded himself in the mountains for 380 years, he was utterly devoid of romantic experience.

This is the story of a powerful yet naive Demon Lord's arduous struggle to find a spouse.
