Science has always tried to undercover the mystery behind magic, and their constant years of mindless perseverance and research led to the outbreak of something catastrophic.
Fifty years ago, scientists accidentally released thousands of ancient spirits to roam the earth, and the results of this was the birth of children with superhuman abilities.
Children whom the scientists believe evolved to the peak of human capabilities. They were called... The Evolites.
Over the years, a new academy has been made for these children, hidden from the public eye. This academy was made to groom them to become the perfect counter measure for the sprites released upon the earth.
However, things take an unexpected turn when a young boy, Rin Okkotsu, gets bonded with the strongest spirit that ever lived, Loki— the god of mischief. He now has to navigate through his new life in the Evolites academy, make new friends and inevitably foes.
As the stakes rises, the spirits also have a master plan to conquer the world, and that plan involves Rin.
