Start with Chinese Kung Fu, Just Throw Luffy into the Sea

Oda, I'm not telling you why you have to give Luffy a "Nika" form. If you can't beat him, just develop some other tricks. There's no need for the protagonist to rely on the big shot. So annoying... Hey, since I'm here, I won't be polite. I'll kill all Luffy and Nika. Next, I will be the protagonist of this world. I will use my skills to disrupt this pirate world.
