A/N: I want to thank everyone who reviewed this story as well as to everyone who added this story to their favourites and follows.


Tsuna furrowed his eyebrows as he gazed down at the set of questions Reborn set for him to revise for the test Uzumaki-sensei decided to set for their class. Was this even middle-school standard? Tsuna wanted to ask the man as he twisted his pen around his finger. It didn't look like it but should he care? He wanted to do well in his test and Uzumaki-sensei always told him that hard questions could sometimes help him to do well in his test.

He wanted Uzumaki-sensei to be proud of him and give him that warm smile that she had been giving to their class more often.

"Is the answer three?" Tsuna asked, flickering his eyes at the set of explosions that was just ready to be pushed by Reborn.

"Wrong," Reborn said, giving him a smirk that just told Tsuna just how much his tutor enjoyed the idea of blowing him up for his mistakes. Just as soon as that thought came to his mind, Reborn pushed down on the handle and it was barely a second later when his bed denoated.

"Where in the world is there a home tutor who uses bombs whenever a student get an answer wrong?" Tsuna couldn't help but ask as his sensei gave him a smirk.

"Right here," Reborn finally answered, earning a groan from Tsuna. "This is just the way I do it, if you think I'll be like Uzumaki then you have forgotten who I am. Besides, didn't you say you were going to study hard for your test to raise your allowance? And how will Uzumaki feel if she find out that her student didn't do well because he lacked motivation?"

"She won't kill me!" He yelled at him. "Uzumaki-sensei isn't violent and she won't say anything about my grades. Besides, Uzumaki-sensei will kill you if she finds out the fact that you've been using explosives as a way to tutor me. At this rate, I'm going to die."

Reborn smirked at him but didn't say anything to contradict his words. As much as Tsuna liked to complain about his tutor, he wouldn't deny the fact Reborn knew Uzumaki-sensei very well. Reborn knew very well his sensei would be disappointed in him if she saw his grades were terrible. If there was one thing Tsuna couldn't stand, it was to see Uzumaki-sensei looking at him in disappointment. She was the only person who believed in him and Tsuna wanted to show her that she was right to believe in him.

"It's hard to disappoint Uzumaki," Reborn said, snapping him from his train of thought.

Tsuna blinked his eyes. "How did y'know what I was thinking?"

"I'm a mind reader."

Tsuna couldn't help but groan at Reborn's words. Seriously, this was his answer to his question? Then again, Reborn's answer made more sense then the explanation Uzumaki-sensei gave him about the huge toad appearing in the middle of school. Kami, did his sensei really believe that he would believe she had a huge toy appear like that? Where would she even keep it? Honestly, when he grew up, he hoped he made believable lies.

Shaking his head, he looked out at the window and blinked his eyes when he caught sight of a black-haired boy holding a gun directed towards them. He glanced wildly at Reborn, who kept his eyes plastered on his textbooks, and then to the black-haired boy. The little boy kept his eyes fixed on Reborn, looking at him with so much hate that Tsuna wondered what the hell Reborn had done to cause so much hate from such a young boy. The second thing which came to his mind was why the hell did that little boy carry a gun?

Wasn't it illegal to give kids guns?

"First, the target is going to be this number," Reborn said, not looking away from his textbook.

"Reborn, there's a weird boy that looks like a cow!" Tsuna said, pointing to the boy. "Look at the window!"

The boy snarled and pulled the trigger, calling out: "Take that Reborn!"

Tsuna waited for the bullet to come out of the gun but nothing happened. He blinked his eyes and stared at the little boy, who blinked his eyes and looked at the gun and frowned. What the hell was going on? Tsuna wondered, wincing as he watched the little boy fall down to the ground from the broken branch. Tsuna rushed to the window, looked down and sighed in relief when he saw that there was no damage to the boy.

"To...Tolerate!" The little boy cried before rushing towards his front door.

The brown-haired boy frowned and glanced at Reborn, who still had his eyes on his textbook. Wasn't he suppose to do something about this? Tsuna couldn't help but wonder as his tutor marked the questions that he should try. This little boy was trying to kill Reborn for some strange reason and while Tsuna didn't like Reborn, he didn't want to see the man die.

He blinked his eyes as he heard his bedroom door being slammed open. Tsuna twisted his head around and groaned as he realized that his mother allowed the little boy into their house without reason. The green-eyed boy grinned at them but Tsuna didn't miss the look of anger in the boy's eyes as he stared at his tutor. What the hell did Reborn do to make that little boy angry? No, wait this was Reborn he was talking about.

Reborn even made Uzumaki-sensei angry and Tsuna hadn't seen his sensei so angry until Reborn came.

"Long time no see Reborn," The little boy declared, pushing the door open. "It's me, Lambo!"

Tsuna glanced at his tutor and asked him. "Reborn, do you know him?"

Ignoring his question, Reborn pointed at the formula in his textbook and said. "Remember this formula, Dame-Tsuna."

The boy, Lambo's eyes darkened at Reborn's words and to Tsuna's shock, the little boy tried to tackle his tutor with a knife in his hand. Reborn didn't even looked away from his book when he slammed his hand against the boy's head, sending him flying into the wall.

"Reborn! He's a little boy!" Tsuna cried, wondering why his tutor was acting so violent to the little boy.

He glanced at Lambo, who pushed himself back up without a problem. Running a hand through his hair, Tsuna couldn't help but notice the fact that even though the boy had been punched severely by Reborn that the boy still looked fine. Either this little boy had a body of steel or maybe Reborn was holding back against the boy but knowing Reborn, Tsuna doubted his tutor was holding back on the little boy.

"That hurt," The boy complained, rubbing his head as he gazed at Reborn with wide, teary, eyes. "I must have tripped over something. I, Lambo-san, five years old from Italy, a hitman from the Bovino Familiga tripped! My favourite food are grapes and candy and I, Lambo-san, who met Reborn at a bar, just tripped-"

Wasn't that sad? Tsuna couldn't help but think as he made a face at the little boy. The little boy just stared at them, gazing at Reborn with curious eyes that Tsuna wondered if there was a reason behind his attacks. No, Tsuna dismissed, the little boy didn't even realized he was hit by Reborn so how the hell could he have a reason behind his attack? It was just his imagination.

The little boy pouted and pulled out a bag from his hair, causing Tsuna to raise his eyebrows at him. He glanced at Reborn, hoping his tutor could explain to him about their current situation but his tutor just ignored him. Maybe, he should follow Reborn's league, Tsuna thought, gazing at the open textbook in the table. He did have a test to study for and Tsuna didn't want his sensei to be disappointed in him.

He lasted five seconds before he checked on the boy again.

The little boy rummaged through his hair, pulling out so many weapons that Tsuna just had to wonder who was stupid enough to give a kid weapons. Tsuna blinked his eyes when he caught sight of a purple bazooka lying on the ground. He glanced at the little boy, who kept glancing at the bazooka as if he was tempted to use it but something kept holding him back from using it.

Maybe the little boy had more sense then he thought.

The little boy grinned and pulled out a gernade from his hair. He glanced at the gernade and then to Reborn, who still had his eyes on the book. Was his tutor ever going to look at the boy? Tsuna wondered, gulping as the little boy kept toying with the gernade. Also didn't anyone tell the boy that a gernade wasn't a toy? No, maybe he could take the gernade away from the boy.

He couldn't have his house explode again.

"Die Reborn!" Lambo yelled, throwing the gernade at his tutor.

Reborn didn't look away from the textbook when he whacked the gernade away, sending it to the boy. The gernade slammed against the boy's cheek, sending him flying towards the trees. That was going to hurt, Tsuna thought, looking out at the window where a huge cloud, which came from the explosion appeared. To his relief and surprise, the boy survived the explosion.

The boy had a couple of brusies on his cheeks and body but other then that, he looked fine.

He blinked his eyes and watched as the boy run away from his house with tears in his eyes.

Tsuna blinked his eyes and looked at Reborn before coming to a decision.

His test could wait but that little boy couldn't wait.


Running was the only form of training that Naru actually did inside of this town. She didn't have to worry about her students getting confused about why there were so many copies of her or had to think of an excuse on why she could do things she could do. No, she could put on her gravity seals and not worry about why she could run as fast as she could since her gravity seals allowed her to run as fast as a civilians.

Well, if she hadn't gotten used to the seal but when that happened, Naru increased her seal to make sure it didn't happen.

She smiled widely at her fellow runners as she runs through the street path that would lead her to the small river which runs through Namimori. She always runs through the way of the town because there was just something about this path, which just gave her peace of mind and what Naru needed now was peace of mind. With Yamamoto nearly killing himself, Reborn annoying and teasing her whenever she was free and, of course, the talk with Yamamoto's father, all she needed was some time to relax.

She stopped running when she caught sight of a little boy crying his heart out.

Frowning, Naru walked towards the little boy and took a seat beside him. He was a cute little boy, Naru thought to herself as she stared at the boy. With his black puffy hair and bright green eyes, Naru wanted to squeeze the boy tight and comfort him especially since she hated seeing kids sad. It was a crime to see kids sad if you asked her because kids were meant to be happy and if they weren't happy then there was something wrong with the world.

Though, the world wasn't fair to anyone, especially to kids.

"Why are you crying, gaki?" Naru asked him, placing her hand on his shoulder.

The little boy sniffed, looked up at her and blinked his eyes at her before answering. "Reborn was being mean to Lambo-san."

"Y'know Reborn? Is he your Dad?" Naru asked, furrowing her eyebrows at him.

It wouldn't surprise her if Reborn fathered a kid, Naru thought, as the little boy stared at her with such curious eyes. He seemed to be the type to father a kid without knowing it especially since his personality gave her the idea that the man was very experienced. She grimaced. What kind of idiot would do it with that perverted man? After all, he seemed to be the type who didn't do committeed relationship. Kids should come from a couple who were committed to each other but Naru knew that accidents happened.

It wouldn't surprise her if Reborn made a mistake with a woman.

"No," The little boy answered. "Papa is gone...Mama says he went up to the sky to become an angel and look over me."

"And where's your Mama?"

"She's gone," The little boy answered immediately, looking down at his small hands as if he was trying to avoid the memories. "Mama went up to the sky to be with Papa."

Naru felt her heart clenched at the boy's words. "I'm sorry kiddo...I lost my mama and papa when I was young too."

The little boy blinked his eyes and held his hand out for her as if he was trying to comfort her. Naru shook her head and ruffled his hair, causing the little boy to giggle and look at her with such big green eyes that just reminded her of the forests in Konoha. She grinned and tickled the boy, who laughed outloud at her actions, looking so much happier then how she found him.

"You should smile more kiddo and whatever Reborn did, just ignore him because y'know why? He might stop being mean if you just don't listen to him," Naru said softly, staring out at the river. "Besides, if he's being mean to you, you come to me and tell me. I'll sort him out for ya."

The little boy blinked his eyes and tilted his head, before asking innocently. "Are you and Reborn like Mama and Papa?"

"Like Mama and Papa?"

"In love," Lambo explained, looking wide-eyed at her. "Mama used to say that Papa only listens to her because they loved each other."

Naru blinked and blinked her eyes as she tried to process the question the boy asked her. In love? Her and Reborn? That had to be the worst thing she ever heard of. At worse, he was an annoyance but at best, he might be the only real friend she had in this small town. Though, Naru never had a friend who loved to flirt with her or who loved to read through her letters like it was their business. It was a miracle, she hadn't hit him just yet for his actions.

But love?

No, she didn't feel any romantic feelings with the bastard.

"No Lambo," Naru answered, smiling down at the boy. "Reborn is my friend and that is what he'll always be."

She frowned when the boy blinked his eyes at her and gave her a smile that eerily reminded her of someone she knew but for the life of hers, Naru didn't know who he reminded her of. Shaking her head, Naru stared out at the river, closing her eyes as she allowed herself to soak in the quietness of the street. For a brief, moment Naru could imagine herself being back home, surrounded by her friends as they made jokes like they didn't have a care in the world.

"Mama says she and Papa were friends too," Lambo said, blinking his eyes innocently at her. "You and Reborn can be like Mama and Papa."

The blue-eyed woman laughed. "Lambo, your Mama and Papa aren't like Reborn and me. Reborn and I are always going to be friends...your Mama and Papa loved each other very much after they became friends."

"What makes you different from Mama and Papa?"

"For one, I won't ever like a guy like Reborn," Naru declared, giving him a smile. "Second, your Mama and Papa must have got along with each other...Reborn and I don't get along."

Lambo tilted his head. "Mama and Papa used to fight a lot. Well, Mama did...Papa liked seeing Mama angry."

"Your Papa sounds like Reborn," Naru muttered. "I swear the man likes to irritate me."

"Then you'll be like Mama and Papa!"

"Y-No."

"Why?"

How the hell did she explain an adult's relationship to a little kid? Naru wondered as she tried to think of a way to explain her relationship with Reborn to this little boy. She didn't understand why he kept insisting her relationship with Reborn would be like his parents' relationship. Reborn and her would be a terrible couple, after all there were just so many times she wanted to strangle the man. He didn't even listen to her whenever she told him to get out of his office but most of all, he kept butting in her business.

He was the most annoying man she knew.

"Uzumaki-sensei!"

Naru blinked her eyes and twisted her head around, blinking her eyes at the sight of Tsuna standing there with worry in his eyes. She smiled warmly at her student before glancing at Lambo, who stared at the older teen with big wide eyes but Naru didn't miss the look of elation on the boy's eyes. This little boy beside her might just have met Tsuna but he seemed elated to see the boy here.

"You met Lambo, Uzumaki-sensei? He didn't do anything did he?" Tsuna asked, blinking his eyes at her.

Naru frowned. "Was he suppose to? Lambo has been nothing but a good boy, Tsuna."

Tsuna blinked his eyes and looked wildly at Lambo, who stuck his tongue out at her young student. Naru couldn't help but giggle as her student gave the little boy a glare for his rudeness. There was something about their behaviour that reminded her of how Konohamaru used to act around her...well until he realized she was a girl. After that, her little brother-figure thought he was in love with her and demanded she was his girlfriend.

Luckily, Naru had been able to make it clear to him she didn't return his feelings and that there was another girl who liked him.

She should ask Hinata the progresss of her sister's relationship with Konohamaru.

"Why are you here Uzumaki-sensei? And how did you meet Lambo?"

Naru smiled and ruffled Lambo's hair, causing the little boy to smile widely at her. "I was out here for a run when I saw Lambo crying because apparently Reborn was acting like an a...I mean he was being mean to Lambo here. So of course, I couldn't let him cry so I spent time talking to him. By the way, Tsuna, what did Reborn do to Lambo?"

"Lambo was throwing explosives at Reborn and well Reborn threw them back at him," Tsuna explained, rubbing the back of his neck.

Naru sighed and shook her head. "Why am I not surprise he did that? It would be something he would do."

"Uzumaki-sensei?"

Taking in a deep breath, Naru looked at Lambo and asked, "Why were you throwing explosions at Reborn? And how did you meet Reborn?"

"I was wondering about that too," Tsuna agreed, taking a seat beside him.

Lambo stared at them for a good couple of minutes before taking a deep breath. "Boss told me to defeat the super first-class hitman Reborn."

So his boasts about being the best hitman in the world wasn't an exaggeration, Naru thought, running her hand through her hair. If Reborn was a great hitman then why the hell would Lambo's boss send him to kill him? They would need to send someone with more experience and while Naru could tell Lambo wasn't a complete weakling, she knew he wouldn't be enough to kill her friend.

Reborn could kill the boy in his sleep.

She blinked her eyes and felt her blood turned cold as she realized what Lambo's Boss had planned. Didn't the man had any sense of humanity? Was he willing to murder a little boy? Naru gulped and looked at the little boy, who stared innocently right back at her. She knew not everyone had a sense of humanity but Naru never thought she would hear of someone who was willing to kill a little boy.

It made her want to find the man and kill him for his actions.

"I met him in a bar," Lambo explained, looking up at the sky. "We spoke about a lot of things even though it was our first meeting. He was the first adult to listen to me even when I was eating grapes while he made funny noises out of his mouth."

"Funny noises."

"He was snoring!" Tsuna cried, causing Naru to sigh.

Well, this explained so much because Naru doubted the fact Reborn would listen to a boy talked about his dreams. The man didn't have any patience with kids if his treatment of Tsuna was any indication. Kami, she felt sorry for any kid he ever had because his kids would be messed up with the way he parented.

"Well since you stopped crying, I can go back home," Tsuna said, shaking his head. "It's time for dinner."

Naru smiled. "Tell your Mum hi and tell Reborn if I catch him reading through my letters again, I'm going to teach him a lesson."

Her student frowned, tilted his head and opened his mouth to ask her something before shaking his head at her and leaving her alone with Lambo, who stared at the fading figure that belonged to Tsuna. Naru smiled at the little boy, ruffling his hair, which caused the little boy to look up at her with a big smile on his face. She sighed and shook her head.

"Y'know I have another room in my apartment and it gets awfully lonely there."

"Huh?"

"You don't have a home do ya?"

Lambo shook his head.

"Then my home is your home and you can consider me your family."

"Can I call you Kaa-chan?" He asked her, looking at her with hopeful eyes.

Naru blinked her eyes at his question.

Kaa-chan? That wasn't a term Naru was used to hearing. In fact, she had never imagined someone calling her that before. All her life, she always thought of becoming a Hokage, of becoming the best kunoichi in the whole world and of course for a brief time, bringing Sasuke back home but not once did she ever consider being a mother. She wasn't suited for it but this little boy wanted to call her mother.

Maybe, he was the only chance she had to have a kid and it didn't help that she already felt a connection with the kid.

Yes, it wouldn't hurt her if he called her Kaa-chan.

"Sure...you can call me Kaa-chan," Naru said, giving him a smile. "I mean I'm going to take care of you aren't I? And y'know what Lambo? I'm going to be the best Kaa-chan you ever have! Believe it!"

The boy smiled widely at her declaration and Naru decided right then and there that she would do everything in her power to make sure the boy smile at her.


It was strange seeing his Kaa-chan like this, Lambo thought as he stared at the woman, who he spent most of his life calling mother. He had been nearly three years old when his boss gave him the 10-year bazooka to use. For nearly three years, Lambo used it and each time he would always see a smiling blond-haired woman giving him treats and telling him to be careful with his bazooka. Not once did she ever tell him to stop using it instead, she would smile at him and tell him stories about her home...well his future-self's home.

Lambo didn't call the woman Kaa-chan until last year when his Mama died from a fever. He hadn't thought of going to his aunt or to his boss to help him. No, Lambo's first thought was to go to the pretty woman. So without thinking, he had used the bazooka during his Mama's funeral. Lambo knew it was rude to do it but he wanted someone to hug him, to tell him everything was fine but no one in the funeral would do that.

Though the pretty woman did and since then, Lambo considered her his mother.

Even though he appeared at the strangest times, his Kaa-chan always had a smile on her face whenever she saw him. She would give him hugs, teach him with her own two kids but most of all, she never once looked at him like he was stupid. Everyone in his family thought he was dumb, even his boss because he didn't try to act like a genius inventor like they all acted but Lambo didn't want to be smart.

He didn't want to be the best because his Kaa-chan lost her most important person since he was the best. Kaa-chan never talked about it but Lambo knew his Kaa-chan wished her most important person hadn't been the best. If her most important person wasn't the best then he would still be here with her and her kids but he was the best and he died because of it.

His Kaa-chan didn't know it but when Lambo appeared in the night when she was sleeping, he could hear her calling out his name, asking him to come back and tell her why he never told her the truth. Lambo didn't know what she meant but he guessed it had to be why Sora couldn't go out a lot. His foster sibling was a meanie, just like his father but Lambo didn't understand why he couldn't go out and play with him like Ren. Not that Lambo played with Ren a lot since he only stayed for five minutes.

Still, he was actually going to watch his Kaa-chan fall in love with her important person and for the life of his, Lambo didn't understand how his nice, pretty Kaa-chan fell in love with a meanie.

His Kaa-chan should love a nice man, not a meanie who always ignore him and a meanie who made Kaa-chan sad. If he didn't want his siblings to be born, Lambo would have tried to make his Kaa-chan fall in love with someone nicer than that meanie. How did his Kaa-chan fall in love with that meanie Lambo didn't understand but he was going to try and understand because his Kaa-chan never made a mistake.

His Kaa-chan was also the strongest woman he ever met so the meanie had to be something for him to hurt his Kaa-chan like that.

"Kaa-chan...why are you friends with Reborn? He's mean and you say you want to teach him a lesson."

His Kaa-chan blinked her eyes at him and laughed. "He's very mean isn't he? Hurting you like that and I hate people who hurt kids...so it makes no sense for me to still consider him my friend but, y'know what Lambo? Reborn might not look like it and he might not show it but he can be very caring...in his own way."

Lambo blinked his eyes at hearing this. For the first time today, he actually heard his Kaa-chan say something nice about the meanie. His Kaa-chan complained to Tsuna-niisan about Reborn but this was the first time he heard her say something nice to him. She also looked different when she talked about him. His Kaa-chan didn't have that sad eyes like she had in the future, whenever Ren asked Kaa-chan about the meanie.

His Kaa-chan looked almost happy, annoyed too but happy and Lambo wondered how could you like someone but be angry at them at the same time.

Did it even matter? Lambo could only just watch his Kaa-chan fall in love with the meanie, he wasn't allowed to interfere with it. Despite what people say about him, Lambo wasn't an idiot. If he was an idiot, he wouldn't have been able to figure out who his Kaa-chan was, or the fact that whatever was causing his sibling's pain had to do with the meanie. If he was an idiot, he would have tried to change the future without thinking of what could be.

As much as he wished his Kaa-chan didn't fall in love with the meanie, Lambo knew without the meanie he wouldn't have his siblings. Besides Tsuna-niisan and Kaa-chan, Lambo loved his siblings even if one of them was quite mean to him but Kaa-chan said it was because Sora was jealous of him. Lambo didn't know why his sibling would be jealous of him.

His sibling could, at least, claimed to be related to Kaa-chan...Lambo could never have that.

"Kaa-chan, why would someone fall in love with someone that was going to hurt them?" Lambo asked her, tilting his head at her.

His mother blinked her eyes and frowned. "Why? I don't know why Lambo, I've never been in love so I can't answer your question but I guess it's because they can't help it. Love isn't something that has reason and maybe people fall in love with someone that was going to hurt them because maybe they thought they deserve it."

"But what if they could do better?"

"It doesn't matter if they could do better, Lambo," His Kaa-chan said, smiling softly. "They can't change their heart or feelings. Maybe for them, that love they had was worth the pain they got...because once you love someone, you're willing to do anything for them or that's what I think. Why do you ask?"

"Mama still loved Papa even though he died and left her alone with me," Lambo lied. "Mama cried for days and days but she doesn't hate him even though he caused her pain."

His Kaa-chan smiled. "Maybe, she loved him so much and the memories they had were more good then bad Lambo. He must have made her so happy that to have him leave her like that...it killed her."

Was that why his Kaa-chan loved the meanie? Did that meanie make his Kaa-chan happy? If the meanie made his Kaa-chan happy then Lambo would do everything in his power to get them together. He wanted his Kaa-chan happy, he wanted his siblings to be born but most of all, he wanted to know what it was like to have a father figure in his life.

If his Kaa-chan liked the meanie then wouldn't that make the meanie his Tou-san?

Though Lambo wouldn't stop the mission his boss gave him because as much as Lambo wanted his Kaa-chan happy, he also wanted to make the man pay for hurting his Kaa-chan like that. He wanted the man to suffer for hurting Sora like that because even though Sora was mean, Sora was still his sibling.

Kaa-chan always told him siblings protect each other and Lambo was going to make the man pay for hurting Sora and Ren.


A/N: Please review and tell me what you think. Also please tell me what you think of Lambo? Is he too out-of-character? And what do you think of his relationship with Naru so far? And I know the kids in TYL is overused however the two kids have an importance later on in the plot.
