Welcome to the era of national lords, where each lord is gifted a random initial unit. Chrono, an unsuspecting lord, is astounded when his chosen unit turns out to be a captivating succubus from the depths of hell. Succubus possess both beauty and strength, relying on the life force and magical energy of their lords to unlock their full combat potential. To Chrono's surprise, he activates the [Many Children, Many Blessings] system, granting his territory growth through the birth of offspring. Thus begins Chrono's irreversible journey of sowing succubus, while fellow lords lead their troops into battle. Years pass, and an army of succubus emerges, numbering in the tens of thousands and wielding unprecedented power. Their swift and merciless onslaught annihilates all who oppose them. Now, Chrono harbors a singular objective: to bring down the sexy goddess or claim them as his own submissive companion.
