A special governmental program has been introduced to counteract the declining birth rates of demi-human races suffering due to a lack of male members. Through a so-called "assistance system," randomly selected humans are required to mate with designated partners—be it elves, sirens, or even dragons. Iris Thea Eaderlindt, an elven princess known for her open-mindedness and friendly attitude towards humans, is transferred to the Ark Metropolitan Academy. Coincidentally, her new teacher has been selected as her mating partner. Anxious yet determined to fulfill her duty of securing the future of her race, she starts partaking in sexual activities with him. To her surprise, Iris discovers that her partner's ancestors were orcs, well known for their extraordinary sexual prowess.
