Try Killing My Little Brother Luffy.

What? Want to be the Pirate King? No problem, it's not a problem if I'm here. Zoro, please don't come over here. I know you want this knife. Okay, okay, I'll give it to you. Look at Zoro, who's all over the place, holding the iron broken teeth and enjoying himself. George, what do you want, top quality ingredients? Wait for me for a while until I catch it. I accidentally traveled to the world of One Piece and caught countless rare treasures casually. One Piece or a dream? If you are not interested in the bandit king, how about making a space king? How do you get to the sky? How about I hook you up with an aircraft carrier, the kind that can fly directly into space? Hundreds of years later, countless people are clamoring to become the Space King and inherit the Space King's treasure... This novel and its characters are purely fictitious.
