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

A Promise

"I've never met someone who pissed me off as much as that guy did," Buggy continued to rant as the two boys glanced at each other and then back at him. "I don't know how you're related to him, and I don't care! That bastard denied me a lot of treasure, so I have the right to say anything I want about him!"

"Treasure again, huh?" Lambo mumbled, his hand tightening on his shoulder to stem the bleeding. "And how exactly did Shanks get in the way of you and your precious treasure?"

Apparently completely ignorant to the boy's mocking town, Buggy answered. "If you really want to know, I'll tell you, but just be prepared to hate him as much as I do!"

"Not gonna lie, I really doubt that," Lambo stated flatly. He was ignored.

"It started when our crew decided to pillage another... I managed to acquire a map that showed me a treasure buried at the bottom of the sea! I kept it a secret from my other crewmates, of course, and planned to go find it on my own once I had my own ship to sail on!"

"Yeah, okay, where exactly are you going with this?" Lambo interrupted, slightly annoyed while Luffy just cocked his head to the side.

Buggy shot him a glare. "I'm getting to that! You see, along with the treasure, we managed to find a Devil Fruit as well! I didn't care about it much at first. After all, how was I supposed to find treasure at the bottom of the sea if the Devil Fruit took away my ability to swim? But after I heard that it could be sold for a million beri, I knew I had to have it! If I sold that, I could get my own ship and search for treasure all around the world! So, I made a fake fruit and ate it in front of everyone while I took the real fruit and hid it away!"

"Ate it?" Lambo asked in confusion. "And your captain just let you do that?"

"Would you stop interrupting?! And, yes, our captain said that if any of us had the guts to eat it, we could," Buggy muttered, glaring at the boy.

"Really? Your captain sounds really cool!" Luffy said in awe.

"ANYWAY," Buggy growled, causing them to look back at him. "Just as I was about to leave the ship, Shanks interrupted me and I had to hide the fruit in my mouth. And thanks to that bastard, I accidentally swallowed it and the map fell into the sea! I jumped after it, but thanks to the Devil Fruit, I couldn't swim anymore, so that flashy bastard had to get me back out!"

"Oh, so he saved your life," Luffy said, nodding in understanding.

"Still don't get why you hate him, though," Lambo muttered.

"HAVEN'T YOU BEEN PAYING ATTENTION?! Because of him, my plans were delayed by ten years!"

'But if it wasn't for him, you wouldn't even have plans,' Lambo thought to himself as he continued to watch the clown with half-lidded eyes. 'Plus, it's your own fault for stealing that fruit in the first place...'

"And then I realized...if I can't have the treasure beneath the sea, then I'll just take all the treasure the land has to offer! With this ability, I'm invincible!" He boasted as the top half of his body split from the lower half and started rising into the air. "And if anyone dares try to take my treasure, I won't let them escape with their lives! Now..."

Lambo blinked in confusion as Buggy's gaze left them and he looked at something in the distance. Turning around, his eyes widened when he saw a familiar girl trying to sneak away, a large white bag slung over her shoulder.

"HAND OVER MY TREASURE, NAMI!"

Nami's eyes widened as she glanced back and she quickly broke into a run. "Crap! He saw me!"
