Synopsis: Kono Sekai de Ore dake ga

In a realm where the value of an individual's life is determined by their Level, Theo, an S-Rank adventurer, finds himself reincarnated a thousand years into the future, a time when society has forgotten the concept of Level Up. In this era, individuals start off as Level 1 at birth, and humanity suffers as the weakest race, living in constant fear of monstrous threats. Yet, among them, only Theo, who has been selected as a sacrifice for the monsters, understands that humans possess the potential to become the strongest, as they alone can Level Up.
