Honestly, This 13th Regression is Getting Tough

I no longer intend to save the world. I won't trust my companions anymore. I'll kill anyone who might become an enemy. Even if they're supposed to be my allies. Thirteen regressions. I've saved the world six times, but none of those endings were the "correct answer".

The man who was once a hero has become a monster through endless regressions. The companions he believed in became traitors, and enemies are everywhere. He gave up his humanity to survive. Are all regression stories the same? This man is different.
