Korean Webtoon Crossover: I’m the Sword Demon King, and I Do as I Please

I'm Kim Min-Soo, the Sword Hero, but right now all that's surging through my chest is uncontrollable rage. Why? Why am I drowning in despair, barely able to breathe, while those bastards can still wear such dazzling smiles?!

Oh, I almost forgot. I'm not just Kim Min-Soo, the Sword Hero. I'm also Kim Min-Soo, the Demon King of Destruction. If this world won't let me live in peace, then I'll do whatever I please. My happiness is the only rule.

The world beneath my feet has long been a rotten hodgepodge. The sword energy of martial arts hadn't even faded before the magic of professional fighters came crashing in. Hunters' dungeons appeared on street corners, and even the melodramatic plots of romance comics had to get involved. This damn world is already a sieve full of holes, so why shouldn't I have a little more fun?

A princess neglected since childhood, hoping to become the center of attention by killing her father and brothers? Fine. Get on your knees and become my maid first.

A male lead who can't stop talking about "redemption"? Sure. Watch me grind your whole family to dust, then we can talk about your bullshit redemption!

A male lead who only knows romance and won't eat? Wake up. This world has always been survival of the fittest. If you won't eat me, I'll eat you. After all, "prey" that goes to waste doesn't deserve to live.

And all those women who came from other worlds, clutching some junk System and thinking they can complete their missions and go home? How naive. I'll crush that lousy System on the spot and keep you locked by my side.

Remember this: I'm Kim Min-Soo, the Sword Hero, and even more, the Demon King who commands destruction. From today on, every rule in this stitched-together world will revolve around my "happiness." I'm going to do whatever I want, and nobody can stop me!
