A/N : ... Seriously, this is something I wrote when I had absolutely nothing to do so... I don't know if it's bad (it probably is) but... Yeah, I just want to write Tsuna as a big brother fic... And after reading a fic about it I just.. My hand typed.. It... self... And the title is... crap.

Lambo lived his boring life in Namimori, going to Nami-mid for his academy, getting chased by the school principal because of his lazy attitude including getting late to class, teachers having bad opinions about him just because of numbers on papers, students who are supposed to be friends avoiding him just because he got home with a limousine. Seriously, what's so wrong with having a long sleek black car for transportation? His older brother even has private jets, helicopters, Motorcycles, and every kind of moving metals as his ride.

But Lambo get trough with it, and do his life.

Every once in a while, especially when holidays come Lambo would fly all the way to Italy with Hibari's helicopter to have a nice dinner with his family. A very nice, good dinner with his family, at least he expected it to be, but it never happened. Every time he get back and threw a bit of grenades, his Tsuna-nii's enemy (paper works) would always multiply to a certain degree where there is only a space for Tsuna-nii to stand in Tsuna-nii's own room.

Lambo had forgotten since when did he respected the person he always call Dame-Tsuna, maybe when he understands that Tsuna-nii always cares for him. He never even complained when Lambo increases more destruction, just welcomed him at the house (mansion) with a big warm smile, happy that one of his family decided to pay a visit.

Tsuna-nii is the best big brother you could ever ask.

Now after nine years of it, after appearing in Tsuna's house in the reason of killing Reborn, Lambo has entered the last day of the last semester of eight grade. He could only hope his days to get better.

"Tsuna-nii, you don't need to take my school report. I can go alone!" Lambo's cheek puffed, his hands gripping his empty backpack.

Tsuna, who has reached the age of 23 this year placed his hands on his hips like an angry mother and started to pout. "Maa Lambo, this is the day to get your report right? I can't come with you last year because of a very important meeting and you didn't tell me about it. Also, here is written that parents or guardians must come to speak with the teacher!" Tsuna pointed at his phone, and opened a mail. Lambo peeked at it and gave a terrified nod, damn, how could that meanie sylark tell Tsuna-nii about it. Oh right, he is the school principal. "So now I insist to come with you."

"But I'm not a kid anymore!" Lambo yelled back, already walking to the limo waiting in front of Sawada household. Yes, he lived there in Namimori.

Tsuna didn't reply, much to Lambo's relief. He entered the car and fidget on his seat, bad feeling. What will happen when Tsuna-nii found out about his grades? OMG OMG they are no good! For a person as great as Tsuna-nii's standards it is no good! What will happen when Tsuna-nii find that report full with his scores? Especially that physic, he failed every test! Lambo saw a drip of his sweat on the ground when he walk past the gates. When he brushed his hand at his forehead, he knew it is cold sweat, it's winter! No no no no this is the start of something not to his good.

Lambo accelerated and climbed all stairs to his classroom with a speed that surpasses Hibari behind him, chasing and muttering 'Do not run in hallways, cow herbivore'. But Lambo didn't care anymore, he had to open that door and made sure Tsuna-nii wasn't there. He ran past all other students that are still waiting for their parents to finish talking with their homeroom teacher. The others eyed Lambo with curious, and frightened stares. Some because they never saw the lazy Lambo to run like this, and some were scared by Hibari.

"Oh, hello Lambo, and Hibari-san." A bright smile shone so brightly that it made some people in the hallway to faint or swoon, mainly the female population. But different from Lambo, who tripped at nothing and fall face-floor. It somehow reminded Tsuna to his past self, and wondered if it had might affect Lambo.

Before Tsuna could ask for his little brother's well-being, Lambo groaned and get on his feet again. "Why are you here Tsuna-nii...? Didn't I tell you to..." He rubbed his chin that hurt so bad after the fall. Now he knew how much does it hurts, when Tsuna-nii's younger he must felt a lot of pain.

"To be your guardian?" Tsuna gave an amused look, wich made the people who just recovered faint again. "And Hibari-san would kill me if I didn't attend, you know why."

Lambo scratched his head and think. Right, everything connected to Namimori is important. "Fine then... But please, Tsuna-nii don't get mad when you see my... Scores... Also can't you wear something less... flashy?" His eyes changed to big bunny eyes, complete with tears on the edge, threatening to fell. But it didn't affect Tsuna very much, apparently.

"I don't have any. And okay, Fon will take care of I-pin's by the way." Tsuna chimed and slid the door to Lambo's classroom open.

Pure silence.

A Nezu Dohachiro who aged quite a bit from the last time Tsuna saw him cleared his throat and braced himself to speak to the newcomer. "Excuse me, but who are you exactly? One of the parents?" He asked while trying to fix his glasses, and Tsuna always thought of it as stupid, knowing it is okay in the first place.

The other parents in the class could just... Stare at the young handsome brunette at the door. Expensive, everything coming from this man smells rich. An obviously branded black suit, white dress shirt, black tie, black cape with golden ornaments here and there, black pants, and black leather shoe, just by looking they could have the thought of ' that must've worth at least a whole company'. And the last, weirdest accessory are a couple of rings, they looked heavy with a kind of gem and chains. The brunette's hair is spiky, unruly and gravity defying, his eyes narrowed and brown in color, he also had matured over years.

Tough the hair had reminded Nezu-sensei of a certain someone. But nah, this young and good looking man can't be HIM right?

"Have you really forgot about me? Nezu-sensei?" Tsuna walked and took a seat in front of his former teacher, Nezu shook his head in disagreement. Tsuna sighed, disappointed. "It is me, you know... Once popular as Dame-Tsuna? Sawada Tsunayoshi?" He pointed at his own face.

And Nezu-sensei laughed, hard. Tears starting to form, Tsuna had to dodge a lot of spit from the teacher's mouth. "Aaah, Dame-Tsuna you say? Don't joke, he's probably cleaning toilets in some junk food restaurant anyway." The rest of the parents also laughed, they have heard of Dame-Tsuna from someone. He is popular from his Dame-ness.

"You mean Dame-Tsuna is the guy who sometimes ran with only a boxer on? You've gotta be joking!"

"I heard he failed every subject in his whole history in Namimori."

"Yep, I wonder what he really do now... A failure like him..."

"Wearing mascot costumes?"

Tsuna felt the burn, great. Did he failed so much in the past that people think of him like that, yes he did fail anything back then but hey, people changes. "TSUNA-NII IS NOT A FAILURE! HE IS THE BEST BIG BROTHER I EVER MET!" Lambo shouted suddenly, making all the class turned his attention to him, he ran out of the class while slamming the door shut, and it cracked.

Tsun is touched by Lambo's words, but also worried about Lambo's safety. I mean, he cracked that door. The school principal won't be happy. Nezu-sensei who was stunned in that few seconds tried to look cool and cleared his throat, "Hm, and what is your business here? I bet you have to spent the last years to buy that suit." Tsuna rolled his eyes, as arrogant as always this Nezu Dohachiro.

"I come here as Lambo's guardian. And I assure you I am Sawada Tsunayoshi. People changes trough time." Tsuna forced a smile. And Nezu-sensei smirked, while his head listing anything bad about Lambo.

"Like I'd belive that..." Nezu whispered it an a low volume, but didn't go unnoticed by the mafia don. "Well, first of all, Lambo is a delinquent, he is always late to school and did not have any friend."

"But it is his choice to choose."

"I'm not done, his grades... Especially physic are horrible, they are way below my standards and he had a bad habit to not listen at the teachers."

"Like anyone could understand you." Tsuna muttered, some parents behind him giggled or the other who don't understand just showed a confused face.

"What did you just say?" Nezu raised an eyebrows and glared at the younger one.

Tsuna gave an innocent smile and shrugged it off by a "No, nothing."

"Fine, and his constant absent from school made his grades drop, then his-" Tsuna is ready for this long lecture of Nezu-sensei badmouthing his family. He prepared ear plugs, wich he quickly placed in his ears, not caring for the fake teacher's blabbering a bit. And placed a fake smile on his face.

After the voices ceased down, Tsuna pulled his earplugs out and threw it at a trashcan nearby. "Are you done? Nezu-sensei? Because I have an important appointment in another ten minutes." Tsuna pointed at a clock on the wall, took Lambo's report and walked out. He could hear sighs of disappointment from behind.

"Wait, I'm not done yet you-"

Tsuna glared at Nezu, if looks could kill Nezu-sensei's in another realm right now. "You had talked only about how bad Lambo's, and now you want to complain even more? If you repeat that again I will personally kill you and your entire family. Excuse me for the intrusion."

No one dared to speak, they just eyed the door until sounds of footsteps ceased and replaced by another "Whoa! you are so awesome Tsuna-nii!"

"Haha, of course Lambo." Tsuna chuckled at his younger brother's tight hug, not caring about some unconscious girls on the floor or the weird stares they received. Tsuna glanced at the report he just take, and he darkened. His bangs lowered, covering any emotions it may show and pulled out his cell phone.

A few seconds after Tsuna typed a number, a person from the other side answered. "Hn. What is it, omnivore?" Tsuna turned the loudspeaker on, the class, and everyone in the hallway could hear it.

"Hibari-san, fire Nezu Dohachiro for having fake academic history and badmouthing students while their grades are passable, about not having any friends, and for himself being an annoying herbivore." The other stayed silent to think of sometime but said a Hn, wich Tsuna translated as "Yes, no annoying herbivore is in my school.".

Nezu Dohachiro's expression was priceless.

Lambo laughed his heart out.

And there it is, what report here is what I mean by a very thin book, filled with all the scores you acquire in a school, also if you are able to go to a higher grade or not, you fail and repeat another year. Usually you will get them in the end of 1st semester and 2nd semester. I don't know if that happens in other countries but it happened in mine. And note that a parent or a guardian has to look at it and sign, also sometimes talk with the homeroom teacher.
