Mythical All-Around Player

Spiritual energy revives, the world changes drastically, monsters rise, humans become the bottom of the food chain, and the era of great destruction arrives. But at the same time, there are also many mysterious ruins around the world. Human beings have learned various abilities through training in these ruins. There are super-powered technologies that are far ahead of this era, there are techniques and moves that can be used to strengthen the physical body, and there are strange magics that mobilize spiritual power to fly into the sky and escape from the earth. From then on, humans began to be able to compete with monsters. Three hundred years after the disaster, an almighty player from ancient times traveled through time. Looking at the various training grounds, he had a strange look on his face. "Wait a minute, what's going on with these ruined training grounds? Sekiro? The King of Fighters? The Witcher 3? League of Legends???"
