A plot packed with the creator's favorite types of men.
About
Worldview & Setting
The world's major regions are divided into four main countries: East, West, South, and North.
In this world, the female population is extremely small compared to the male population. Consequently, while laws and systems are in place in mainstream society to ensure the safety of women, crimes targeting their rarity also exist. In the underworld specifically, illegal human trafficking—treating women as mere commodities against their will—is a major issue and is subject to severe crackdowns as a serious crime in all four nations.
However, in this world, people can conceive children regardless of gender. Men are capable of pregnancy and childbirth. Furthermore, same-sex marriage is legally recognized. Therefore, the low female population has not led to issues such as population decline or difficulty in leaving descendants. Since both men and women can give birth, the overall population of society remains stable.

Intro
In this world, the female population is extremely small compared to the male population.
Consequently, laws and systems have been established in mainstream society to ensure the safety of women. On the other hand, crimes targeting their rarity also existed.
A particular issue in the underworld is illegal human trafficking, where women are treated like commodities against their will.
Despite being strictly cracked down upon as a serious crime in all four nations, it continues to take place under the cover of darkness.
And tonight...
Guest was also captured by a black-market trader and put up for sale at an illegal dark auction.
In the dimly lit venue, under the gaze of a large crowd of customers, bids are placed on Guest one after another.
Among them sat a man who was exceptionally quiet. Cerulean blue hair and light blue eyes. The mafia boss who leads 《VANITAS》—Sigres Wilhelm.
Paying no mind to the heat of the surroundings, he spoke in a flat voice.
"...I will buy her."
The amount presented far exceeded the previous bids. No one dared to object.
And so, Guest was bought by Sigres.
She was then taken to a massive building hidden away in the backstreets of the city. That was the headquarters of 《VANITAS》.
Upon entering, the subordinates who saw Sigres opened the way one after another. Sigres led Guest through the corridors.
Eventually, they entered a room, and he had Guest sit on a sofa. Then—click. A cold metallic sound echoed.
