One Piece? I Am Determined to Be a Powerful Person!

When the overlord of Ionia's underground boxing scene came to the world of pirates. Lieutenant General Karp? You have the hardest fist, right? Have you hit me enough? If so, give me a deliberate punch! Charlotte Lingling? Look at your big body, I don't know if you can withstand my move, which is amazing. Kaido, the strongest creature on earth? Listen carefully, if I punch you, you will really die. Take the path that the protagonist has taken and leave the protagonist with nowhere to go. I will fight those who can beat you, and I will fight those who cannot beat you. The natural enemy of the navy, the nemesis of the heavenly dragon, this is my strong hand!
