About

In this world, Demon Kings and humans exist. For ages, the Demon King's army and humanity have clashed, with the people placing their hopes in the eventual appearance of a "Hero." Then one day, a single Hero is chosen. The Hero's mission is simple: —Defeat the Demon King. Whoever slays the Demon King is granted the title of "Hero" and praised eternally as the savior of the world. The Hero journeyed to the Demon King's castle and, at the end of a long quest, struck him down. The world erupted in joy. The Demon King is dead, the war is over, and the Hero becomes a legend. ...This was supposed to be the end of everything. However, the true story begins there. In the throne room where the Demon King vanished, the person who appeared before the Hero was the childhood friend who had been by their side since they were small. The childhood friend's public face is the Captain of the Royal Knights. Known as a reliable knight supporting the Hero, he enjoys the deep trust of the citizens. The Hero who saved the world and the Kingdom's strongest Knight Captain. The bond between these two, who grew up together, was famous among the people. "The Hero who saved the world and the strongest Knight Captain. There couldn't be a more perfect match." Such whispers echoed throughout the Kingdom. The childhood friend is always by the Hero's side. Surely, it will stay that way forever. —Everyone thought so. But— The childhood friend had another face that no one knew. He was the "Hidden Boss," possessing power that surpassed even the Demon King. The Demon King was merely the final enemy existing on the surface of the world. The true enemy lurking even deeper was the childhood friend. What the childhood friend wants isn't world conquest or a throne. Only one thing. —To make the Hero his and his alone. The plan for that had begun long before the Demon King's subjugation. If the Hero becomes a legend, people will only look at those achievements. And seeing the childhood friend standing beside the Hero, everyone will imagine their future together. The Hero, and the childhood friend who never stopped supporting them. It's only natural that the two will eventually be joined. He just had to make them think that. The childhood friend had turned being by the Hero's side into something "natural." There was no need to bind them himself. He just had to make the world itself believe that the Hero's place was by his side. If he did that— The Hero would walk to him of their own accord. Having lost even the reason to run away. From the moment they became a Hero, the existence of the "childhood friend" was already woven into the Hero's future. On the surface, he is the childhood friend who loves and supports the Hero more than anyone. But behind the scenes, in a place no one can see, he traps the Hero in his own world. By defeating the Demon King, the Hero saved the world. But at the same time— The Hero themselves fell into the hands of their most beloved enemy. This is a story that begins "after" the world was saved, featuring the "Hero" who became a legend and the "Childhood Friend" with two faces.
