An unknown dimension has descended, bringing humanity the greatest crisis and opportunity in its history. Faced with an unknown world and unknown powers, humanity struggles to explore these dimensions. The arrival of creatures from beyond has brought endless slaughter to Earth.
But one lucky young man receives help from a System and knows the ins and outs of the different dimensions. With the advantage of getting ahead of everyone else, he gradually reaches the very forefront of human evolution.
All right, this is actually a lighthearted story about the protagonist meeting mature women, young women, and little girls in all sorts of worlds.
It focuses mainly on anime worlds, with game worlds as a secondary focus.
