A brief description of the manhwa Never Die Extra:

Extras die every day in various ways in the game [Demon King’s Palace 3]. He was an extra when he reincarnated into the game. I’ll never die. Never. “Let’s get started.” Evan had come to a conclusion. He tapped his cheeks as a way of signaling to himself that he had made up his mind. He would become a character who never dies.
