Tenkawa Noboru's mission, as instructed by Kirika, is to impregnate ten thousand oni girls. This is a village of "Oni Nyūjo" – girls who grow horns and become oni if their breasts become too large. Their libido increases proportionally to their breast size, making self-control impossible. A welcome arch of magnificent breasts!! A never-ending forest of breasts… Crushed and drowned by the oni girls breasts, the welcome celebration of the breast village continues.
