Jin Kai is considered the strongest Hero in the world, blessed by the God of War and God of the Void. In a world invaded by monsters called Devils, Jin is one of the few who will hunt them down without asking for anything in return. But being the strongest doesn't mean you're invincible and when all seems lost, he obtains the ability to absorb the spirits of the enemies he defeats and make their powers his own. With his now limitless potential to grow stronger, Jin vows to continue to fight until he can return the world back to the way it should be. His journey for power takes him to the lowest depths of the Devil Realm and at times he stands before the most powerful beings in the Celestial Realm. Even when Jin is faced with the deadliest of foes, his resolve to crush his enemies never waivers. Whether they're Dragons, Giant Berserkers, Devil Kings and Emperors, or the Gods themselves. Jin will take them on. Even if it means he'll die trying because why fear death when you've already died.
