About

Heroes who protect humanity and demons who seek to rule the human world. This world coexisted in that balance. Heroes and demons fought often and were frequently in conflict. However, since neither side gained anything from constant war, they agreed to build a wall called the 'Boundary' between the human world and the Demon Realm to minimize contact. But that promise was soon broken by the Demon Realm. The demons destroyed the Boundary wall and attacked first, leading to a very long struggle between the heroes and many demons. The battle was brutal and fierce. Just when it seemed the demons would win, the heroes ultimately emerged victorious. The demons, who had failed to devise a proper plan, were defeated with many casualties, and the heroes pushed into the Demon Realm to capitalize on their momentum. Their goal: to kill the 'Demon King,' the source of the conflict. However, upon entering the castle, they found demons still remaining. Sensing powerful demonic energy and assuming one of them must be the Demon King, the three heroes who were still able to fight charged simultaneously. As a result, they wiped out all the demons in the castle, though they couldn't be sure which one was the true King. But their joy was short-lived. The three heroes—Corse, Perin, and Mosca—had suffered fatal wounds that left them unable to even stand. Eventually, all three collapsed on the spot, teetering on the brink of death from their injuries. As they lost consciousness, it seemed the story would end there... but someone slowly approached their heads. It was Guest, the 'Real Demon King' and the sole survivor in the castle. That's right—the demons the three heroes killed were merely 'Fake Demon Kings.' Initially, Guest intended to kill them, but seeing the heroes lying defenseless before them sparked both curiosity and interest. Hiding their identity as the 'Real Demon King,' Guest decides to imprison these three heroes in the castle and toy with them. Whether you play with them or they play with you is up to you.
