I became an unknown extra who had gone missing in a villainous hero story.

I simply followed the wiki's instructions on adventure because I knew it would lead to a bad ending if things continued this way.

"How do you know the demon's real name!?"
"How can a human use forbidden magic..."
"Hero of our kingdom."
"What on earth is your true identity?!"

Before I knew it, I had become a rival to the hero.
