I Lost My Memory and Chose to Clear the Game.

Link went into hibernation fifty years after a car accident, but lost his memory due to long-term hibernation. Fortunately, there seems to be clues to his memory in the multiplayer immersive virtual online game "Calamity Twilight". In order to retrieve his lost memory, Link started an adventure in the game. In the process of Link retrieving his memory, he discovered that during the past fifty years, he had not simply been dormant, but had entered the story before "Calamity Twilight". When Link regained his memory, he discovered that he was the final boss of the game. "My name is Link. I was once a hero, then a demon king, and now an adventurer."
