This is a first/second draft. I've dropped it in favor of further developing the idea.

When I died on death row, that should've been the end. Except I was transported to a new world with a System where I was the forgotten third son of a powerful duke. I tried to live a normal life, but I was executed for my family's treason. After that, I regressed back to when I was 17. Six different times.

So it's time to try something different─like learn magic and exploit this stupid System to Hell. Maybe literally. Whatever it takes, right?

Unfortunately, the System might already be exploited to Hell and I'm this world's only chance at saving itself from being annihilated by demons. All I have to do is kill the strongest one of all.
