One Piece: Easy, I’m Whitebeard, Not Malphite

Ionia is surrounded by Noxus, and on the brink of destruction. At the critical moment, the Wuju Bladesman, Master Yi, is transported to the world of Pirate King. There, he will find the companions from Valoran who were lost in this world. Then he will lead them back to Valoran to save Ionia. From then on, Yi begins a directionless search... Whitebeard: “It’s true that I can make the earth shake, but I’m not the Malphite you’re talking about!” Marco: “I’m the Phoenix, not Anivia!” Hawkeye: “I am the World's Greatest Swordsman, sure, but I’m really not Yasuo!” Red-Hair: “Hawkeye is indeed my brother, but I’m not Yone either!” Kizaru: “What? You say my name is Ezreal?” Buggy: “That’s right, I really am a clown!” Yi: “You’ve all lost your memories. Just come back to Valoran with me, and you’ll see!”
