“God is Dead.” It had been 15 years since dazzling beings of golden light uttered those words, and the world had never fully healed. Ishitake Yuuji only had vague memories of his parents, but the scars of the Cataclysm were plain to see. The fear in the eyes of people when they mentioned the terror of that day surrounded him for as long as he’d known, and even still they dreaded to think of the demons lurking in those abandoned cities. But he wasn’t like them. Raised with an iron will and strong faith, he had mastered the art of humanity’s newest weapon - spirit. Echoes of a higher being given form, spirit came in all shapes and sizes, and with a new generation of children raised in a post-Cataclysm world, humanity could finally begin fighting back. After the appearance of a mysterious horned girl, the cogs of fate begin to turn. Yuuji must join Phoenix, a pioneering academy built to train the best and brightest demon hunters the world has to offer, and together with his friends and classmates bring humanity back from the precipice.
