[You have been killed by the Hero of Light.]

[You have died.]

I had died at the hands of the main character in the novel I had read before.

But I got another chance. I regressed and returned to the time when I first entered this novel world.

Once again, I live in this novel world as an extra character.

Since I have experience and knowledge, especially my World System which had upgraded, I'll do what I want to do.

I will become stronger than the main character.
