From Mafioso to Pirate (Katekyo Hitman Reborn x One Piece)

Pirates' Battle

"I'm here to kick your ass, just like I promised!" Luffy shouted at the clown, smirking as he let go of his hand, which floated back to its owner and snapped into place.

"It's you four again!" Buggy snarled down at them. "So you actually had the guts to come back and face the mighty Captain Buggy, huh?!"

"Yare, yare. He has no problems with modesty," Lambo sighed before turning to look at Nami. "You should probably get back."

Nami humphed and glared at him. "I'm just here for the map and treasure, so don't try to get me involved in your fight, got it?"

"Right, right..."

"What... What are you kids doing here?!" The mayor shouted, coughing. "This is my town, and I'm going to protect it! So don't get in my way!" He grabbed the weapon he had dropped, a homemade wooden spear, and charged forward once again.

And then Luffy grabbed him by the head and slammed him face-first against the nearby wall.

Every single eye stared in disbelief as Luffy dusted his hands off, letting the old man fall onto the ground, unconscious.

"What the hell are you doing?!" Nami shrieked at him. "Why would you do that?!"

"'Cause he was in the way," Luffy said flatly, smiling.

"What the hell are you talking about?!"

"Hey, that's good thinking," Zoro spoke up, causing her to look at him in disbelief.

"That old man would have gotten himself killed. This is for the best," Lambo stated before looking at the unconscious man and wincing. "...Though this might have been pushing it a bit. I don't think limbs should bend that way..."

"There is something wrong with all of you," the girl grumbled.

"Alright! Here I go!" Luffy interrupted as he turned his attention back to the clown and took a deep breath.

Lambo's eyes widened slightly. 'Luffy, are you gonna do what I think you're gonna do?'

"HEEEEYYY! STUPID BIG NOOOOSE!"

He couldn't resist facepalming. 'He is. He really is. Fine, let's just get this over with...'

Next to him, Zoro stood a bit straighter, his hand tightening around his sword, while Nami just shouted "WHY WOULD YOU SAY THAT?! YOU IDIOT!"

"...You're really pissing me off, kid," Buggy growled, gritting his teeth. "No one has insulted my nose and lived to tell about it! That includes you, Cow-Boy! Don't think I've forgotten!" He added, pointing his finger at Lambo, who blinked.

"You're still upset about that?" He asked in disbelief. "That was literally hours ago!"

"I'm the kind of guy who keeps grudges! FIRE THE BUGGY BALL!"

"Damn it, this is all your fault, you dumbass!" Nami shouted at Luffy before turning on her heel and running away.

"Maybe we should follow her example?" Lambo asked nervously, taking a few steps back.

"Oi, Luffy, let's go!" Zoro shouted as well.

To their surprise, their captain just smirked. "Don't worry! That won't work on me!"

"What are you talking about-" Lambo started, trying to talk some sense into the boy, but he quickly shut his mouth, completely baffled by what happened next.

"Gomu Gomu no..." Luffy took a deep, deep breath, causing his body to start to expand at a rapid pace. "Balloon!"

Nami, along with every pirate within viewing distance, had their jaws drop as they watched the cannon ball sink into the boy's now massive stomach before being flung back with a force.
