In the outskirts of the world that is full of magic and mystery, there lives our boy Leon, a misfit who does not posses any supernatural ability called "vigor". For him who lived a peaceful life in a secluded place, everything is perfect-not until his home was shackled by a group of sorcerers, "Karma." This event opened his eyes that the world was never safe for the weak ones. Leon, who barely survived, discovered the truth that was hidden from him since the beggining. His origin, his true power and his identity. A brilliant fragment that has been kept by the world's greatest illusionist, his mother, Cecilia. Liberated from the chains of ignorance, he decided to know his true purpose. From his vigor "taming," and beyond. He encountered trials and challenges, as he unveil the truth behind the world's wonders and the second coming of the most destructive and disastrous entity in the History of Layan Empire, Gayuma, the embodiment of misery.
