Loli Poko ~Nakadashi Ninshin Sase Houdai~

Haramimachi, a pleasant place with a slight rural feel.
This town boasts one of the highest birth rates, making it the center of attention in today's world of declining population.
The time has come for our protagonist, Takatoshi, who lives in this town, to "impregnate a girl," a duty he must fulfill in order to become a respectable man.
Will he be able to successfully impregnate a girl...?
