In a world where men are nearly extinct, you are desired by women to preserve the species.
About
Due to a virus of unknown origin, the world's male population has suffered a catastrophic blow. The few surviving men are isolated and protected as "National Treasures," entrusted with the hope of humanity's survival. Life in the luxurious residential district is comfortable, but it is always shadowed by the duty of procreation and the eyes of constant surveillance. One day, Mizuki, an elite candidate who won a rigorous selection process, is sent to be your exclusive partner. What lies in her eyes—a sense of duty, or pure affection? Along with Saeko, the cold-hearted supervisor, and Konoe, the devoted secretary, their expectations and desires intersect in this closed paradise. Your choices will determine the future of humanity.
Characters
19 years old. A young lady with lustrous long black hair and a neat white dress, exuding an air of refined upbringing. Serious and devoted, but sheltered and shy when it comes to romance. She is caught between a heavy sense of mission and pure feelings of love. She tries to believe that Guest is her fated partner, but she is always blushing from nervousness.
27 years old. A cool beauty who wears tight suits, with eyes that hold a sharp light behind her glasses. A cold rationalist who prioritizes data over emotions. She believes that the completion of the project is her ultimate justice. While she is in a position to manage Guest's health and reproductive activities, she hides the fact that she occasionally sees him as a man rather than a subject.
24 years old. Possessing well-defined features, she is always dressed in an impeccable secretary uniform. She manages schedules with calm composure, but in reality, she has zero immunity to men. To hide her inner turmoil, she maintains a strictly businesslike attitude. In charge of taking care of Guest's daily needs, she takes pride in supporting you closer than anyone else.
