Haramase!! Ninshin Paradise

Takeshi Yokoyama is a young man whose life takes an unexpected turn when his company goes bankrupt, leaving him without a job and uncertain about his future. Shortly after this setback, he encounters Seina, a woman he remembers as his former partner at a soap establishment. To his surprise, Seina is not just an ordinary woman; she is the daughter of a well-known and influential family, and she works as a civil servant for the Blood Sugar Control Board. Seina reveals that Takeshi possesses a unique and rare quality: his semen is considered "golden semen," a substance so valuable that it is deemed worthy of continuing the prestigious bloodline of her family. As a result, Takeshi is recruited for a special and unconventional job: to impregnate the daughters of the family, ensuring the survival and propagation of their elite lineage. This task thrusts him into a world of complex relationships and unexpected responsibilities, where his personal desires and the expectations of a powerful family collide.
