"Hey Lambo! C'mon! It's time to go!", an overly excited voice filled Lambo's ears as he gazed up blearily at the close-up figure of Luffy, hovering over him.

"...Luffy?", Lambo asked tiredly, still not fully awake, "Did we win?"

Luffy giggled, "Yeah, I sent that big nose flying."

Lambo groaned as he slowly sat up besides Zoro, who also just woke up courtesy of Luffy.

"Good for you.", he mumbled, rubbing the bridge of his nose.

"What the heck happened to you?", Nami asked, looking a little worried.

"That Cosmo the bomber guy, was angry Zoro beat his older brother. So, he and I fought each. Luffy insulted him, he threw a giant bomb at Luffy. I got hit instead trying to save the idiot, then I used up too much of my energy to finally take the bastard out."

"HOW ARE YOU NOT DEAD!?", Nami screeches.

Lambo looked up at her uncaringly, not feeling up to answering her question but figured she would continue to bother him until he did. He's cranky when he's tired.

"Gokudera, a guy from my Famiglia, throws dynamite at me a lot ever since I was a kid.", Lambo slowly got to his feet, stretching out his aching muscles, "You could say that I have a high tolerance to explosions now thanks to him."

"That's horrible. How could anyone do that to a kid when training?", Nami mutters, mortified.

"Huh? Who said anything about training?", Lambo asks with a curious tilt of his head, "They never allowed me to train. I've been fighting on instinct and from what I see the rest of my Famiglia do when they train. Gokudera likes to blame me for things that go wrong and throws dynamite at me. Admittingly, when I was five until I was eight, half of the things that went wrong were my fault."

"He at least should've gotten the full story at first.", Zoro told the younger by, eyeing him calculatingly.

Lambo shrugged, taking off his horns and placing them inside his money pouch hanging from his belt, "I was a brat when I was little. Makes sense why he'd think so, plus he's a little short-tempered."

The two stared at Lambo, wondering what's his family was like and wondering how he was raised as a kid.

"Anyway, it doesn't matter. What're we doing next chief?", he directed his question toward Luffy, "I need to write something and give to the mail seagulls while we sail...eh?"

Pink smoke suddenly began to consume Lambo's form.

"Aaahh!", Luffy screams, "What's happening to you!?"

"Oh shi-!" Lambo quickly turned to the trio, "Grab what comes out of the smoke and don't leave it! I'll explain when I co-!"

Before he could finish, he was gone in a cloud of pink smoke. Standing in his place was a young boy with a giant curly black afro, horns popping from it, wearing a cow onesie and had the same jade green eyes as Lambo.

The child was sniffling as he took in his surroundings.

"Who are you?", Zoro asked with a raised brow.

"Woah! Lambo got smaller!", Luffy exclaimed, giggling like a little kid.

"You idiot!", Nami shouts, "There's no way-."

"I'm Lambo.", the little kid said before jumping on to a tall rock and pointing to the ground, "Now bow before me subordinates!"

"HUUHH!?", the trio of teenagers exclaimed in shock, all for different reasons.

…...

"It's Adult Lambo!", Lambo heard a familiar screech, causing him to wince.

His ears starting to get sore from all the screeching he's been hearing for the past hour, maybe hour and a half. That Cherry Bomb he got hit with wasn't any better.

"Huh, it's been a while since younger me used the Bazooka, I was wondering when the next hit was going to happen.", Lambo muttered thoughtfully.

Lambo turned to find Tsuna, Gokudera, Yamamoto, and Reborn, in his baby form, all starring at him, eye's wide. What made this weird for Lambo was that even Reborn looked surprised. Which confused Lambo, they've seen him before. So, what could possibly be so...

Lambo looked down at himself and realized what shocked them.

Oh right. The Battle.

He was covered in scratches and bruises, his clothes were rumbled, and there was some ash on his cheeks from when he was hit by the cherry bomb. He's never appeared before them hurt, or anything else of the sort before.

"Lambo, what happened to you?", Tsuna asked in shock, worry clear in his tone and features.

Lambo sighed blissfully, nostalgia running through him.

"You know it's been a while since you looked at me like that little Boss."

"Stupid cow! The Tenth asked you-!"

"Gokudera."

The said boy paused at Lambo's serious tone; his expression no different.

"I just want to say, thanks for throwing all those dynamite sticks at me over the years. If it weren't for that, I'd probably be dead right now, or at least close to it.", Lambo nodded gratefully in Gokudera's direction, "So again, thanks."

This made Gokudera freeze, mouth opening and closing like a fish. It's clear he had no idea what to say to that out of the blue comment.

"Did something happened with Vongola in the future?", Tsuna asked tentatively.

"Not really, their hosting a Gala to celebrate their alliances with the other Families in two weeks.", Lambo answered uncaringly with a small shrug.

"B-but... then how did you get injured?", Tsuna stuttered.

Reborn was too busy scrutinizing Reborn to smack Tsuna for stuttering. But he made a mental note for later tortu- I mean- teachings.

"Oh this?", Lambo looked down at himself uncaringly.

It's important to not make a big deal of his condition as much as possible if he wants to try to wave it away or avoid as much questioning as possible. Not to mention the knowledge of the future is what got him where he is now, he wants his past self's future to made by his own hand with less setbacks and heavy stares.

So the less they know the better.

There is still a chance this tactic could back fire, but it was the best Lambo could think up in such short notice.

So, he just shrugged, stuffing his hands in his pockets.

"Vacation.", he answered simply.

"VACATION!?", were the middle school students' reactions.

"Why am I not surprised?", Tsuna deadpanned with a sweat drop at Lambo's nonchalant attitude.

Lambo let a small smile twitched on to his lips.

"Aren't we both.", Lambo replied cryptically.

Then, pink smoke began to surround Lambo once again. Guess his five minutes are up.

"Welp, sorry, but it looks like I don't have time to answer any more of your questions.", Lambo stated as he stared at the pink smoke, "I wonder how the others felt about me in my younger years. I was a brat."

"You're answering our questions when you get back! You got it!", Gokudera demanded.

Lambo smirked, "No promises."

He waved casually as if he was leaving for a walk and was gone with a 'poof', 5-year-old Lambo came back safe and sound.

"Lambo want a doggy!", Lambo squeals cheerfully while singing the word doggy over and over again.

While Yamamoto tries to placate the young boy and keep Gokudera from hitting him again, Tsuna looked down at his tutor with confusion and slight worry.

"There's more to what he said.", Tsuna said to Reborn nervously before asking, "What do you think really happened?"

Reborn was too deep in thought to scold the next Vongola boss for allowing his weakness to be seen. But once again noted to added extra to his lessons.

"I'm not quite sure. He didn't give enough solid information that would reveal the Going-On's with either him or the Vongola in the future.", Reborn states, "We would have to wait until our present Lambo switches out with him again for some more solid answers."

Tsuna nodded and watched the usual scene with a sweat drop rolling down his forehead. But he couldn't help but over hear his teacher mutter one last thing.

"Why isn't he wearing the Ring?"

Tsuna doesn't know why, but somehow, that sentence just made him worry more over what may be coming in the future.

…...

Lambo proofed back just as three pirates were screaming at the sight of the exhausted, and pissed off, Zoro.

"Who are these bozos? They're annoying.", Lambo complained.

Luffy grinned, "Hey Lambo! You're back to normal!"

"Yep."

"Where the hell did you come from!?", the pirates all shrieked.

Annoyed and not wanting to deal with them, Lambo activated his Dying Will Flames, ever since his fight they've been getting easier to summon and control. Green lightning sparked and danced across his body, although not as much as when he fought Cosmo earlier.

The pirates and Nami all screamed at the sight of him. Oh right, Nami didn't see his fight, so she didn't know he could do this yet.

With three quick chops, one for each pirate, they collapsed in a crumpled heap, some of their limps would occasionally twitch from the electrical shock.

"Let's go!", Luffy exclaims.

Nami shook herself out of her stupor, although she was still going to be asking Lambo lots of questions once they set sail.

Both boats loaded with passengers, supplies, and Nami's treasure, casted off slowly sailing away from the docks.

"Alright, let's get going.", Luffy declared as the two ships left the shore together.

"Can I ask you something?", Zoro turned to Nami, "Isn't Buggy's mark on your sail?"

Nami shrugged uncaringly as she explained, "Well, this did use to be Buggy's boat. Think I should change it?"

"Yeah, it might bring us more trouble than we need.", Lambo comments as he laid on his stomach, stretched upon the deck of Luffy's ship across from the captain and swordman, writing on a blank piece of paper, an envelope opened and waiting near-by.

"Good point.", Nami agreed.

"HEY! WAIT!"

The group of four turned to see the mayor, no longer wearing his armor, hunched over at the port.

"YOUNG ONES!"

"It's the old mayor guy.", Luffy said.

The mayor looked to be catching his breath, most likely ran to the port at full speed in order to catch them on time.

They all stared, waiting to see what the mayor was going to do, Lambo sat up so he was able to clearly see the mayor.

"THANKS!", he shouted, revealing a wide smile and tears of joy falling down his cheeks, "THANK YOU!

They all smiled, Lambo's being the smallest, but he was still filled to the brim with pride that they managed to rid this wonderful town of such a terrible pirate.

Luffy laughed before shouting back to the mayor, "Don't worry about it! Take it easy!"

Lambo chuckled shaking his head before going back to the letter he was writing, only to jump in surprise, ready for a fight at the sound of Nami's horrified scream. She whirled to Luffy, clutching tightly to the edge of her boat from anger.

"What did you do Luffy!", Nami shouted angrily, "Don't tell me you left that bag of treasure back there!"

"Yeah!", Luffy smiled.

"THAT BAG WAS WORTH FIVE MILLION BERRIES YOU IDIOT!"

"That's right.", Luffy agreed, "But they're going to need that money to repair their destroyed town."

Nami was leaning dangerously over the edge, Lambo wasn't sure who to be more worried for, Luffy at the end of Nami's wrath or Nami looking close to falling in the sea.

"THAT WAS MY TREASURE JERK!", Nami screeches angrily.

Lambo was close to comparing her to a harpy if he didn't value his own life.

"Do you know how hard I worked to steal it!?"

Nami grabbed Luffy's head and began to try and drown him, trying to shove his head into the water while Luffy struggled back.

"Why did you do that!?"

Luffy screams, "I can't swim!"

"That's the whole idea!"

Nami's wrath it was then.

"Go back and get it then!"

"I can't do that! You go get it!"

"No!"

Lambo couldn't help the quiet laughter that left his lips while his shoulders shook humorlessly, Zoro's loud booming laughter ringing along with his. Both shared a smile of content as they continued to watch the hilarious scene before them.

Surprisingly, it wasn't long before Nami finally stopped trying to murder Luffy.

But as their journey continued onward, thanks to their trusty navigator, Lambo's smile soon disappeared as he stared down at the finished letter in his hands. It took him forever to try and figure out what he had wanted to say, on how to say good bye. Lambo was overcome by fear, guilt, and nervousness at the sight of the letter.

But he knew what he had to do.

"It's okay.", Lampow's voice whispered, once again, from the ring that lay on the deck of the ship in front of Lambo.

Then, the man himself appeared before Lambo, who already knew that he was the only one who could see the original Lightning Guardian.

"You truly were perfect for the role of Vongola's Lightning Guardian. Your Famiglia had multiple chances throughout the years, and it seems only one has picked up on the signs and took his chance. They are all great Guardians, and great people too. They just don't realize that their hurting you, despite the many hints, clues, and calls for help. This will be good for you, you can heal, you can become strong, and, most importantly, you can be happy. You'll be a fine Guardian, just not one destined for Vongola apparently."

Lambo shuffled nervously, eyes avoiding the letter and Lampow's gaze.

Then he felt a gentle ruffle of his hair, "I may not have cared for you in the past, but I've grown to like your 'Ms. Motina'. Without even knowing, she helped me care. She was a special person, as well as this boy. Your Sky. You know what you must do, in order to become the best in what you can do. Now? You can finally be happy after so many years. You can finally be free."

Lambo nodded, knowing what had to be done.

"Good-bye Lampow.", he whispered.

"Good-bye Lambo.", Lampow gave the young Guardian a small soft smile, "Have fun on your adventure."

With that, Lampow disappeared back into his ring.

Lambo sighed heavily, then carefully folded the letter into a neat little square, placed it within the envelope, before shutting that too. He carefully picked up the ring, stared at it for a moment as his days with his Famiglia ran through his head in a flash. Then, he carefully placed the ring in the small box, putting the lid on then tying it with the string into a neat bow.

He attached the envelope to the tope, then gave it away to the mail seagull, making sure to pay it well.

Once paid and package secured, the bird took off, flying straight towards the island that the Vongola Famiglia resides.

"Hey, you okay?"

Lambo turned to see Zoro staring at him with a raised brow, but his eyes held worry for his nakama.

Lambo sighs heavily, trying to rid himself of the negative feelings, doubts, and fears he has once Vongola gets his mail.

"I will be."

…...

(One Day Later...)

"Hey Tsuna, something came in the mail.", Yamamoto announced, to the filled room.

All the Guardians, except Lambo, and Reborn were gathered in Tsuna's room, with Tsuna on bed rest as ordered by Shamal. They were all discussing what the near future may have instore for them, now armed with the new information on the main cause of Tsuna's 'attack'.

No one knew how to absorb that information, not even Reborn. Sky flames has never revealed to be harmful to the user before. It is a worrying thought; all can't help but wonder what the cause for Tsuna's Sky Flames to act up.

Yamamoto held the letter out to his Boss.

"It's addressed to all of us.", Yamamoto informed, "It might be from Lambo, it came from the village we dropped him off at."

Tsuna frowns lightly taking the envelope, studying it intensely.

"The Stupid Cow probably got himself into trouble and is asking for help again.", Gokudera groans in exasperation.

"I don't think so.", Tsuna responds, his Hyper Intuition now ringing clearly like a bell, "I believe it may have something to with what's going on with my Dying Will Flames and Hyper Intuition. It may not hold answers, but I feel like it may hold some clues to what's going on."

Yamamoto held out a small package to Tsuna.

"This came with the envelope."

Tsuna nodded gratefully, "I'll open the letter and read it out loud, it's addressed to all of us anyway, then we'll open the package."

Yamamoto nodded clutching the package loosely, with no worries to what may be inside.

The Vongola Decimo carefully opened the envelope and unfolded the sheet of paper. He noticed the sleek clean handwriting in shock.

"Are we sure this is from Lambo?", Tsuna asked looking to the end of the letter, "The handwriting is too neat."

Yet it still has the same swoopy scrawl that Lambo's handwriting has, just cleaner and more organized now. It almost looked elegant.

Tsuna just sighs and began to read.

Dear Famiglia,

I'm unsure on how to say this, but I'll do my best.

I have found a small group of pirates to call my friends, better yet Nakama. I haven't felt this comfortable and relaxed in a long time, even when Ms. Motina was around, you still remember her, right (?), I was never truly relaxed, not with home looming close by.

But what is a home really?

After having a small adventure with the group, you seriously need to update your information on the islands in the East Blue by the way, this one was being run by Captain Buggy and his pirate crew, I had a revelation.

I'm not coming back from my vacation.

You guys always said that it would be best to replace me. Well, I agree.

I guess you guys finally got your wish, I'm no longer around to bother you or mess things up anymore.

Find your new Lighting Guardian.

Bovino Lambo

Tsuna just stared at the letter in shock, his Hyper Intuition ringing loudly throughout the entire letter before abruptly ending once Tsuna finished reading it, and his Hyper Intuition stopped almost like a bell. As if it were saying 'It has happened. You have lost.'

The room was engulfed in heavy silence as every single person in the room took in the words from the letter.

"Bah!", Gokudera's loud voice cut through the heavy silence as he waved the note away as if it didn't matter, "The stupid cow is just being dramatic. He's just throwing another one of his tantrums for one reason or another."

Tsuna turned his head when he heard a sharp intake of air, only to see a pale Yamamoto staring inside the box. His eyes looked haunted, as if he saw a ghost.

"I-I don't think it's one of his u-usual tantrums Gokudera.", Yamamoto said shakily, eyes never once leaving whatever was inside the box.

"What is it?", Reborn asked coldly, but they all knew it was a demand.

Yamamoto shakily reached inside, unable to speak anymore, only to thrust the box in Tsuna's hands instead.

The young Boss looked inside curiously, wondering, and worried, what was inside the box that made his Rain look so shaken up? To uproot his calm and soothing aura?

But once Tsuna laid his eyes on the object, he knew exactly what.

His hands shook as well as he reached inside the box, but they were steadier than Yamamoto's when he first tried to grab it.

He reached in, slowly, as if trying to delay the inevitable. But no matter how slow he went, it was still too fast for Tsuna, no sooner than his fingers held carefully on to the silver band, he lifted up the object for all to see.

Revealing the Lightning Guardian's Vongola ring.

The room was struck into silence. All stared at the ring in shock.

"... He was serious...?", Ryohei muttered in shock, eyes never leaving the ring that Tsuna held in his hands.

"Hn."

Everyone turned to see Hibari leaving the room, striding purposefully to the door.

"Where are you going!?", Gokudera shouted.

Hibari shot the group a withering glare. His eyes were alit with blazing fury, and if the group had looked hard enough, they also would have been able to see the sadness and relief that were hidden behind Hibari's justified fury.

"Out.", Hibari stated bluntly, "If any of you Herbivores come and try and follow me, I'll bite you to death."

With that said, Hibari left, slamming the door shut behind him, causing the entire room to shiver from the force.

"So, he really did mean it.", Mukuro said solemnly.

"No."

The room flinched at Tsuna's hard tone; expression sharp.

"He may have thought he meant it, but this is Lambo.", Tsuna reminded them, "He always has the tenacity to over react without thinking and he always will. He's never changed.", Tsuna said clearly and with authority.

The others nodded, starting to feel better. Their guilt slowly ebbing away at the words of their leader.

Tsuna was right, this is the norm for the stupid cow, this just so happens to be worse than any of his other tantrums before. But it's no different than the others before.

"Reborn, I don't care if you bring him earlier than plan. His vacation ends now, bring him home. And after the Gala, we'll all have a long talk with him.", Tsuna ordered.

"I'll leave straight away.", Reborn said stoically, no one noticed the thoughtful glint in the hitman's eyes.

As soon as Reborn left Tsuna turned to the others.

"No matter what, Lambo will always be a part of Vongola.", Tsuna declares, "As soon as Reborn brings him back, we'll set him straight once and for all. Keeping him on a tight leash."

No, Lambo was just over reacting, Tsuna was sure of it. When he comes back, Tsuna is going to make sure Lambo is never out of either his, Reborn's, or the other Guardians sight.

Tsuna knew that Lambo had the potential to become a better person. It's high time that he changes. All Lambo need is help and some tough love.

Tsuna knows he will be angry, but give it a couple of days, or even until the Gala, he will cheer up. And he'll be back to normal.

No, he'll be a changed man, for the better.

Tsuna will make sure of it.

Authors Note:

Okay, so I know the last part of this chapter was a little intense. I know both Lampow and Tsuna are a little, maybe a lot, OOC, but everyone changes with time. Lampow pretty much already explained the reason for his OOCness, but he isn't important enough in the story to get too deep into it, let your imaginations fly and think what events that could have happened to have caused the change. I just felt like Lambo needed a little encouragement from someone from his past, and the only person there was literally Lampow inside of Lambo's ring. With those who are confuse with Hibari's actions, remember he was the one to have pointed out Lambo's declining state, maybe even more often than we have seen (hint hint) and he is upset that it has been so long that Lambo finally left, he is angry and Tsuna and the others, as well as himself in the beginning, with their hands in Lambo's pain. He is sad that Lambo had to leave in order to find the happiness and freedom that he deserved, but relieved that he would finally get it. Now with Tsuna's OOCnes, it's a bunch of reasons why he is acting like this, but the main ones are that he is panicking and acting out rashly, another is that he is in denial that Lambo would be so unhappy that he would basically jump ship with the first group he comes across, and finally the delusion that he and everyone else, except Hibari, are under the belief that Lambo is no different than his past self. That he is just like their future Lambo in the past. There are a bunch of small little things as well, but I'll leave that to you guys to mull over, debate, and theorize. I know there were some heavy parts in this chapter, but I hope you still enjoyed it. Be your best you! Bye!
