A government-approved smartphone was supposed to make a virgin impregnate everyone, but... As part of global measures against ultra-low birth rates, the government formally decided to distribute smartphones with an "induce pregnancy" app attached for men who can impregnate. Finally, after longing for it, the unremarkable virgin student Nagata got his hands on the one-month induction privilege. The first person matched with him was Mitsuki Shiori, a beautiful girl who had just transferred to his school. She seemed to have some darkness about her; whatever the reason, she was definitely troubled in some way. Unaware of this, Nagata naturally believed that induction would work and approached her to perform impregnation under the guise of induction... Little did he know that this encounter would be the spark for a major event later on.
