In the year 2000, "holes" to other dimensions suddenly appeared worldwide. Passing through these holes led to "dungeons" infested with creatures that attack humans, commonly known as monsters. Within these dungeons and inside the monsters' bodies, "magic stones" could be found, which garnered attention as a new resource and energy source.

Furthermore, connecting with the dungeons allowed people to gain magical power and use "magic." However, at the same time, a strange illness that caused men to die became prevalent.

On top of that, for some reason, the male birth rate plummeted drastically, transforming the world into one with a 1:99 male-to-female ratio by 2030.

In such a modern society, notions of chastity were almost completely reversed, and men were considered precious.

"Men are special and should be protected. Women must continue to strive to be strong, kind, and beautiful in order to protect men and be chosen by them."

This was the prevailing thought, and polygyny was accepted, with values such that being chosen as one of a man's wives was a source of pride.

Consequently, many men were favored by laws and systems, leading indolent lives.

The protagonist, Itsukushima Ittou, comes from a village on the verge of depopulation and begins living with his aunt. Having grown up in a unique environment, Ittou accumulated effort under his grandmother's teachings: "Women are to be protected, and men must continue to strive to be strong, kind, and robust." He moved to the capital with the mission of "finding a bride" and transferred to a prestigious metropolitan co-ed high school.

When such a rare, hardworking man conducted a "Bride Recruitment Dungeon Stream," the world was thrown into a frenzy!

This is a modern harem fantasy set in a world with a 1:99 male-to-female ratio and reversed notions of chastity. It follows a high school boy who, completely ignorant of the world's ways, arrives, continuously strives to be popular, challenges dungeons, and unknowingly captivates women – all thanks to his earnest misunderstandings!
