[From the Author who brought you "Player Who Returned 10,000 Years Later" & "I’m Not a Regressor"]The first time I realized that I 'couldn't die' was during a practical training exercise in my third year as a hero cadet.

And now, after hundreds, even thousands of years, I was still alive. I was the only one still alive."But now… it’s finally over."After wandering for millennia, I thought I could finally put an end to this grueling existence...“Dale! Dale Han! How dare you sleep during my class? You've got some nerve, don’t you?”“…Huh?”But what awaited me at the end of my long existence wasn't a period, but a repeat sign.
