逆転世界に流されて ～男が希少な異世界で生き抜くハーレムライフ～

College student Sota Akizuki is thrown from his ship by a storm's massive waves and prepares for death――. However, when he wakes up, he has washed ashore on a mysterious island. While wandering the island, he meets Phyllis, a beautiful girl in strange attire. After nursing her back to health, Sota realizes that this place is another world. In this world, men are rare, born only once every thousand people. Because of this, the "Kingdom" and the "Empire" are constantly at war, fighting over men. Men stay away from women, and women crave men――a world ruled by a distorted balance. Sota tries to act naturally while hiding his situation, but that "normalcy" seems to be what makes him so "extraordinary" (alien) in this world…!? In a world where even the mere existence of male sexual desire is a "cheat," he melts away the strong and beautiful women!
