Extra in Destroyed World

King of Extras (narrated by MC): "Alright, listen up, folks! You ever hate a story so much that you swear you'd rather die than live in it? Well, bad news: I *died* and guess where I ended up? Yup, inside the very trash harem novel that made me want to throw my phone across the room. But plot twist—I’m not even the hero. No, no. I’m just an extra, a background mob. My job? Well, the original protagonist—let’s call him ‘Mr. Harem King’—he gets all the girls, the power-ups, and oh yeah, also *destroys the world* by the end. Nice work, buddy. Guess who’s here to clean up the mess now? Yours truly. Now I got to save the world on my own by training hard. I’ve got no cheat system, no special blessings, just a sharp brain and a bigger...uh, sense of survival than my last life. My goal? Not getting crushed in the waves of someone else's story and trying not to get incinerated by demon gods. So buckle up, readers—I’m rewriting the script, one stolen plot twist at a time. And Don't expect Harem here, I fucking hate that shit."
