Just a guy minding his own business but then tragedy struck. Sent back in time thirteen years in the past, he relived his school days not without a partner in crime. A system in his head, he thought he was crazy but it was real, but a bigger surprise waited for him. The past didn't seem like the past that he knew. A past with heroes and villains running around in the world with each day world-ending events kept on happening. What should he do? Turn into a hero or be the bad guy? Better yet should he be just a bystander and mind his own damn business? Well, we'll see.
