In a world reshaped by the dawn of Quirks-extraordinary superhuman abilities-the first spark of change came in the Chinese city of Qing Qing, where a child radiated light from their body. From that moment, humanity began evolving in unprecedented ways, with nearly 80% of the population manifesting powers that ranged from the miraculous to the bizarre. Society adapted, forming a new superhuman structure where Pro Heroes stood as paragons of hope and justice, battling villains who sought to exploit their gifts.

It all began in Keikei City in China with the news that a bio-luminescent was born. After that, "exceptional" individuals began popping up all over the world. The cause was unclear. Time passed and the "exceptional" became the norm and fantasy became reality. At present, 80 percent of the world's population consists of superhumans with special abilities. Hero; a profession that everyone once dreamed about entered the spotlight. However, not all people are born equal and there is still a part of the population without these exceptional abilities. Among the ordinary or those who do have the ability to be a hero still exist the exceptional few who influence the world their own way. This lead to the creation of the nano-machines called Nanites. They were made with the intent of saving mankind by eliminating diseases, ending world hunger and possibly extending a human's lifespan. But it would seem that these mini machines have an even greater effect than just that. It would cause a change, the likes no one has seen before.
