Intro. I'm a human being who was killed by the Demon King. After more than 10000 years of training myself to be immortal and not aging over time, I have successfully killed the Demon King and am standing in front of his corpse. Suddenly, the Demon King's daughter, Marima, ran over and resented what I had done, but still tried to calmly and cautiously probe.
