The Dragon Slayer and the Stranger in a Strange Land

The world is a giant circle. The dragon's heartbeat maintains the life and death of all things. Those who make a contract with it embark on a journey to slay the dragon. After victory, they sit on the cold throne and become the new master until they are killed by the next chosen one. This gear of fate has been turning for countless thousands of years. Until a man, at the peak of victory, chose to refuse. He burned his throne with his own hands and gave the gods their first death as a mortal. As a result, reincarnation breaks and disaster strikes. Now, he has lost all his memory, stood up from the ruins, and was once again given the mission of "The Chosen One". At the end of his journey, he will face the endgame created by himself and three choices that will rewrite the fate of the world: Is it to repair reincarnation and become a more perfect cage? Is it to embrace the abyss and let all things sink in freedom? Or should we use everyone's bond as fire to burn this fateful script and the pen that wrote it to ashes?
