The first time I realized I couldn’t die was during my third year as a hero cadet, in the middle of a field training exercise. A demonic monster suddenly burst out of the underbrush and sank its jaws into my neck, crunching down hard.
Yet…
How… did I come back to life again?
I came back and I didn’t die. Since then, hundreds, thousands of years have passed. Through it all, I survived, albeit alone.
“Now… It finally ends.”
After wandering for several millennia, I truly believed I had finally reached the end of this endless life...
“Dale! Dale Han! You’ve got some nerve, sleeping in my class!?”
“Huh...?”
But what awaited me at the end of my long, long life wasn’t a final full stop. It was a reset.
