My name is Lan Yuxing, a high school student. After dying, I was transported to another world and possessed the body of a slime—Rimuru, also known as the "Cute King," because he's so cute. One day, I discovered that the world I'd been transported to was worse than I'd imagined, because the whole world was so chaotic! The Western Hemisphere has vampires, werewolves, and archangels, while the Eastern Hemisphere has Iron Man and the Hulk. There's also a guy named Luffy in the ocean, and in a place called the Hidden Leaf Village, there are two guys named Naruto and Sasuke who are actually arguing about who gets to fight...

I've arrived in the world of One Piece with the Tenseigan, and I'll be the freest person on this great sea!
