Worm (Parahumans #1) - Chapter 285: Venom 29.4

In every story, there exists the hero and the villain, the protagonist and the antagonist.And like every story, the hero always wins, and always gets the girl.But what happens now that I died and became a villain in the last book I read? Not even a proper villain, but one that the protagonist kills in the early chapters.I don't want to die again, and I don't want that simp of a protagonist to walk all over me. Maybe I should just become a better villain.I've always admired the smart badass villains that took on the protagonist. Maybe I can be one of them, maybe I can win—the first villain to win against the hero.I'll rewrite this story into one where I become the greatest villain. Call me sick or evil, but it's my time to shine.

And he plans to use every drop of blood, eldritch ritual, and demonic summoning he can to kill them.
