Chapter 1: Ambush

Year had past ever since Caelum turned five

"Caelum" Someone called as Caelum turn to the person who called him. It was his mother coming beside him.

He was currently in the Vongola Mansion's library where he was reading encyclopedia alone and quiet. His mother came with tray of snacks for him.

"How are you doing Caelum? Did you find that book interesting?" Tsunayuki asked her son. Caelum smiled as he reply, "It is mama, I can't help but read more!"

Tsuna smiled for him and pat his head, "Good, your papa would be happy if he heard it."

"When will papa come home?" Caelum asked in wonder. Tsuna thought for a moment, "Your papa said something about business trip so he might be gone for three or four days but don't worry, once he's back he'll give you another lesson you like."

Caelum was happy to hear that.

Caelum loves to read books whenever he has nothing to do, especially bored. He reads the books his father gave to him as a gift from his job and time to time he comes to his uncle's library to have a quiet time and borrow books to read them. He was really smart for his own good, much which made his parents proud.

Tsuna put the snacks to his side, "Caelum as much as I don't want to interrupt your reading, I think it's time for break. Come on, that could wait."

Caelum pouted a bit, "Okay"

He took his bookmark which was a gift from his uncle Lampo and put it on the page he was currently reading before closing the book. He took his snack which was a portion of chocolate cake and eats it. It seems it was so delicious that he was smiling big. Tsuna smiled for her son and seen a cream to his cheek, she took a napkin and wipe it, making Caelum laugh.

The moment between them was truly great.

Later in Giotto's office, Tsuna and Giotto were talking there privately.

"You want to visit the orphanage?" Giotto questioned after hearing Tsuna's request. Tsuna nod, "Is it not okay Gio-nii?"

"Huh? N-no its fine Tsuna." Giotto said, "But I think you need someone to escort you. It would be dangerous if I only let you and Caelum goes alone."

"But it's not like we're heading to a dangerous place right?" Tsuna questioned her over protective brother.

Giotto sigh, "Yeah but I'm worried about the time before you arrive there. What if an enemy famiglia recognize you and attack you? That is something I won't let it happen, most of all Reborn! I don't want to be killed."

Tsuna mentally sweat drop, her husband's threatening really affects his brother both physical and mentally… well she knew it wasn't just her Gio-nii but everyone in the household does.

"I'll call him so I could inform him our visit. It won't be long and we'll be back before midnight." Tsuna said with a smile.

Giotto smiled, "That's good to hear. Still I won't let you both go alone. I'll have someone to escort you there and guard your safety." He said before taking something out to his drawer and began looking at everyone's schedule.

Tsuna tilt her head, "But everyone are busy so there's no need right? I mean… Natsu-nii with his Guardians except Chrome were all in Europe to do their secret mission, Alaude and Daemon Spade on the mission, Lampo visiting a relative and-"

"Asari, G and me are heading to a famiglia meeting." Giotto finished, seeing everyone's schedule, no one was available to escort her. "Chrome is pregnant so that's definitely a no too. Natsu would be angry if I ever done such thing."

"Don't forget Elena too." Tsuna reminded, making her brother pale as he remember how scary that woman could be.

"I-In any case I still can't allow you to go on alone" Giotto said firmly, making Tsuna sigh, "Your choice Gio-nii but be sure not to appoint too many bodyguard. I can't let the children there be scared because of our arrival."

"I know Tsuna." Giotto said with a smile. That was when an idea came to his mind, "Maybe I should ask Lancia to escort you."

"Lancia?" Tsuna questioned, not remembering meeting him.

Giotto nod, "Don't worry Tsuna, you can count on him and I must say, he's good with kids." Giotto reassured, making Tsuna happy to know that. Giotto turned back to the paper in hand, "Oh Basil is available too. How about it Tsuna? Are those two good for you?"

Tsuna nod, "If you think they're capable then its fine Giotto-nii. I trust your decision."

"Thanks Tsuna"

After the talk, Tsuna went out to call the person she loves from the phone. It was ringing and Tsuna was waiting for the person on the other side to answer until he finally did.

"Chaos" The person greeted, it made Tsuna happy to hear his voice.

"Reborn is it a good time for me to call?" Tsuna asked, bit worried that she might have call in a bad time. She heard the man chuckle, "Its fine. What's wrong?"

"Just wanting to inform you that me and Caelum are planning to visit the orphanage today. Is that okay to you Reborn?"

"Beside you and Caelum, who else?"

"Giotto-nii said Basil-kun and a man name Lancia will escort us."

Reborn hum to the names, "You still haven't Lancia right?"

"Y-yeah… I trust Giotto-nii's decision and he did say he loves children... but I'm kind of nervous."

Reborn chuckle to his wife, "Don't worry Tsuna, I could assure you he's safe."

"Really?"

"Don't you trust me?"

"You already know what I will answer right?"

The two laugh, feeling the affection even they are apart.

"Come back safely Tsuna. I'll be back in next two days." Reborn told his wife. Tsuna nod, "Okay, I love you."

"Same here"

Tsuna put down the phone and smiled, her husband never fail to make her happy.

Soon when Tsuna and Caelum were ready to leave, they saw Basil standing beside the car they'll use with someone whom she doesn't know. Tsuna was currently wearing long light pink skirt and orange with white blouse.

Basil smiled and greeted her with large grin, "Tsunayuki-dono, Caelum-dono your servant is glad to see you again."

Caelum pouted, "Drop the horrific and don't call yourself Servant, you're my playmate!" He argued. Tsuna added, "We're also friends so there's no need for that Basil-kun."

Basil laughed a bit, "Well I was studying England's greatest empire times and I got absorb by it."

Tsuna and Caelum gave a little laugh before turning to another person whom they don't know.

Basil introduced him, "Tsunayuki-dono, Caelum-dono this is Lancia-san, another person that will escort you on your way visit."

Lancia bowed for respect, "Please to meet you Vongola Decimo's Sister and her son."

Tsuna smiled, sensing no danger and seems a good person even if he has a bit scary image. She bowed as respect, "I'm Tsunayuki Sinclair and may call me Tsuna, this is my son Caelum, please to meet you Lancia-san and please take care of us for this day."

Lancia smiled as how welcoming she is. This made Caelum see he's a good person, he smiled, "Please to meet you."

"Same here" Lancia replied before opening the car for them. Basil spoke, "Now shall we go?"

Both nod and entered the car. Lancia took the driving sit while Basil was beside him and drive away.

From bit afar, Giotto, G and Asari were watching them, seems about to leave as well.

"There they go." G said before turning to his best friend and boss, "Let's go Giotto."

"Huh? Y-yeah" Giotto said, seems trouble in mind. Seeing that made Asari question him, "What's wrong Giotto? Are you worried about them already?"

"Well a bit but I'm sure they can protect Tsuna and Caelum Asari… just that…"

"Just that?" G questioned, wanting Giotto to continue his words. Giotto thought for a moment and shook his head, "It's nothing. Come on and let's go."

The two nodded before the three took their car and left the mansion.

Inside the car, Caelum was silently looking out the window, watching cars passing over them, people walking, shops and so forth. Tsuna took this moment to have a chat with them.

"Lancia-san I never seen you before. Mind if I ask your position in Vongola?" Tsuna asked, truly in wonder. Lancia smiled as he looked at her from the mirror and answered, "I work in deeper part of Vongola. You can say the Vongola's own jail. My duty is to be a guard the prisoners, making sure they're alive and so forth."

Tsuna seems trying to imagine that since there are actually rooms that she wasn't permitted to enter. She only asked her brothers or her husband and thankfully they answered and explain for her. Knowing it was part of Mafia businesses, she didn't pry more than that.

"It seems a tough job." Tsuna murmured, making Lancia chuckle, "Not much and I see that you don't want to enter that place."

"Gio-nii might get mad so I won't." Tsuna said, "So does that mean you interrogate them too? You don't hurt them much right?"

"Those jobs were the Hibari brothers. Also, no need to worry for they are safe, we're not hurting or killing them just to find answers Tsunayuki-dono." Basil answered instead.

Tsuna nod and turn back to Lancia, "Lancia-san can you tell me how you end up in Vongola? Just wondering."

"It would be my pleasure."

The talk continued as they drive. Caelum was listening from the conversation, not talking to ask or butt in. He was very interested to Lancia, he can feel his flame inside him which was strong and restless but hot, kind and loyal. It was like what he always felt every time he's with Uncle G and Uncle Hayato.

'Lancia… he has a Storm Deathperation Flame.' Caelum thought as he observed Lancia.

Truth to be told, after he became five years old, he felt something strange happened to him. He can feel disturbing feelings to every people he met or see. Slowly, he can see something inside the a person without knowing which scares him that he can't help but cry alone to his room, not wanting to be discovered that he was crying but failed when his father sneak in and saw him crying. Caelum told his father the reason and he felt scared, which his father soothe him and began to explain to him what he was seeing.

He discovered that he could see flame inside to every people which they call Deathperation Flame or Dying Will Flame. His father had shown his flame in front of him that really surprised him. His father explained more and so were each characteristic of each flame and finally understood. Caelum finally understands that this power is not something to be scared but thankful as a gift. He was happy that his father was there to explain to him and there to guide him. Now, all he has to do is find a way to control it.

How he got this power? It was inherited from his father. When Reborn became a Curse Arcobaleno, each one of them gained an eye to see people's flame, no exceptions. Now the curse is gone and back to their true bodies, the eye was still there but didn't mind and let it be, knowing it will be useful sooner or later. But to think Caelum had inherited such eyes, it was indeed surprising for Reborn.

The only one who knew about Caelum's power was only his father, not wanting to make misunderstanding and most of all, be found out. His father said it was for his own safety which he obeyed.

Without realizing, they finally stop in a certain store which Caelum turn to his mother in question, asking why they stop knowing the orphanage is still not haft away.

Knowing her son's silent question, Tsuna answered, "For the children who stay the orphanage Caelum. Would you like to help me find a gift for them?"

Caelum smiled and nod, "Sure Mama"

They soon brought many new toys and mostly books for the children. Both mother and son somehow share the same thought about giving kids books more than toys since toys can help children to understand and image certain words such as truck, car, dog and etch while books could give open more learning that they will never find in any toys.

"Were this too much?" Tsuna questioned, not knowing if they are enough or too much. Basil shook his head, "I don't think so Tsunayuki-dono, if ever there are many, I might think they would still enjoy it."

Tsuna nodded, "Your right Basil-kun. Now where's… ah"

Tsuna saw both Caelum and Lancia who carries two big baskets of fruits. It seems her son knew what she last needed and asked Lancia to buy it with him, truly got from his father. Tsuna nodded with a smile, it seems its all settle.

Arriving the orphanage where Tsunayuki grew up and met her husband, the children flooded out and gave a tackle hug to Tsuna. She smiled as she hugged them back. Some children who knew Basil since he came before to escort her were pulling him in to play with them again while other children were curious about the new face which was Lancia. Caelum who able to get out the flow greeted the person who takes cares the children in this orphanage.

"Aunt Michel it's good to see you again." Caelum greeted the girl who seems same age as his mother and care taker. Michel smiled and leaned down to hug him, "I miss you Caelum. So how was your day with your parents?"

"Great as always!" Caelum shouted his answer in great happiness that made Michel smiled, knowing full well how he love his parents more than anyone.

"Michel it's been a while." Tsuna said as she hugged her best friend and so was her. Michel answered, "Its great and I must say, the Vongola Corporation truly helped us on our every needs. Please tell to Giotto that I'm very grateful for his charity."

Tsuna smiled and nodded. She only knew Vongola as a biggest business Corporation, not a mafia.

"Michel I have a bunch of gifts for the kids. Mind helping me?" Tsuna asked as she pointed the car. Michel giggle, "Tsuna you shouldn't have trouble yourself."

Tsuna just smile to it and Caelum decide to go back on the car first, taking few things that he could carry and brought them out, followed by Tsuna and Michel.

Later on, Tsuna was enjoying with the kids, same for both Basil and Lancia who seems doesn't mind at all. Caelum on the other hand was sharing his knowledge to others who kept asking (demanding) him about many things. The care taker adults still can't believe he could explain things that are too easy for younger kids to understand.

"What made you visit here Tsuna? As I remember, you visit here when your husband was around, not him then your brothers or his friends." Michel suddenly asked, seeing Basil and a new person which he found it questioning.

Tsuna smiled and answered, "Everyone is busy and... there's actually something I wanted to talk about privately. Is that okay?" Michel noticed the worried eyes of Tsuna, immediately nodding and smiled, "Feel yourself at home."

"Gladly do"

Everything went well as they all enjoy their stay until evening arrived and about to leave. The kids said their good bye and thank you before they all went in the car and left the place. Caelum's eyes seem slowly closing and yawn, sleepy and tired from playing with them. Tsuna smiled as she pat her son's head and pulled him to her which he obligated and sleep beside him.

"Caelum-dono seems tired." Basil commented as he watched the child sleep. Tsuna giggle but not loud for her son to wake up, "It seems to be. He always does every time me and Reborn went home. He's too hype don't you think?"

Basil smiled while Lancia spoke, "True and I must say, I'm surprise Caelum wasn't being bullied or crying there."

"What do you mean?" Basil asked. Lancia sigh and explained, "The kids in the orphanage, didn't you notice the jealous eyes they had every time Caelum was there? I can actually tell he can sense that and in very young age he understood and adjust himself for everyone. It was the real reason you came to visit right?" He asked in the end as he looked to Tsuna on the mirror.

Tsuna was looking down before nodding, telling it is. Basil was shock to this, "But the kids seem so cheerful and they were all getting along with him." He reasoned.

"Not all. You didn't notice some kids were giving a glare on Caelum? And almost all the kids were faking their smiles and acting as if they were all getting along. I'm really impressed to your son's riding and most of his entire acceptance to everyone. Instead of feeling angry, he just accept and do what he can to make them entertain and happy, just like how his mother was doing for everyone." Lancia said, truly shock Basil while Tsuna felt even sadder on how those kids treat her son like that. She knew her son didn't do anything bad, so why?

"I wonder why they treat my Caelum like that. I asked Michel if she knew something but she didn't and that's when she realized all the kids were all talking about me while my Caelum doesn't exist at all." Tsuna said in pain tone.

"So you didn't get it." Lancia said before turning the car on the left and continue driving. "The reason why the kids don't seem to like Caelum was because they were all envious to him."

"Envious? Why?" Tsuna asked. Lancia kept driving for a second until the street light turn red that they stop. "Because he has something that they all don't have… family. They all don't have a family like him which is you and him." He simply answered that made Tsuna even more sadder as she turn to her sleeping son.

"It makes sense" Tsuna whispered but two could hear "The orphanage was trying to give them a new home, even so they aren't satisfied and some doesn't want to be adopted. 'Real family was better', are the words the kids feel when they see Caelum with me and Reborn right?"

Tsuna slowly stroke her son, feeling sad for the kids whom she can't do anything but wait until the day they would be adopted and hopefully could give them a better love and life than a real family they could ask for.

The traffic light turn green and the car moved ahead.

Basil seems to understand the kids, since he too was an orphan and was only saved and raised thanks to Iemitsu.

"Don't worry" Lancia spoke, making the two turn to him. He smirked, "I'm sure someday those brats could see their own life once they grow up. Growing is part of life, and so are changes."

Those words made the two smiles. Basil grin, "That's right. They don't understand right now because they're still growing but once they do, they would finally understand and soon walked on their own to find their own happiness right?"

"Yeah" Tsuna said, agree. For some reason, the heavy feeling was lifted from her chest. She turned back to her son and slowly kissed his forehead. "Thank you Caelum, such a good boy."

Unknown to her, Caelum's lips smiled, seems half awake and decide to sleep, entering dream land.

Somewhere on the road in other location, Giotto was resting inside the car as G kept driving while Asari was quiet, making sure Giotto could rest his mind from his headache mafia meeting.

Giotto gave a deep sigh as he try to relax himself and closed his eyes, wanting to relief himself that finally it's over when suddenly, his eyes shut open as something was reacting to his mind. His Hyper Intuition was reacting, truly mad. It was shouting something that he can't help but clench his head, making the two turn to him in worried.

"Giotto what's wrong?" G immediately asked as he looked to Giotto at the same time watching the road in front of him.

Giotto continued to clench his head, trying to understand why his hyper intuition was reacting like this. Slowly, he turned to them in wide eyes.

"Tsuna"

"Giotto?" Asari questioned. Giotto began to shout in panic, "G find Tsuna and Caelum, quickly!"

Not understanding but obligated as he took a U-turn and drive away.

Somewhere road, Tsuna was slowly drifting in sleepiness, wanting to rest herself when suddenly her head hurt.

Her intuition was reacting, shouting danger. Tsuna's eyes widen, "D-danger" she whispered.

Basil was about to ask when suddenly, the car's front right wheel was shot, making the car lost control as Lancia was trying to take back its control. Another wheel from the back was hit as the car began to spin around that woke Caelum completely and Tsuna hugged her son to protect him.

"Hold on!" Lancia shouted as he used the force brake as the car was sliding in great force until they end up hitting the post from the side. The car was crushed, broken mirrors and can no longer drive away.

Inside, Lancia was adjusting himself before turning to the others, "Are everyone alright?"

"Y-yeah?" Basil answered in low tone, hands in heads as trying to stop the spinning.

Caelum's eyes were shut but when Lancia asked them and realizing the spinning stop, his eyes slowly opened before looking up to see his mother was hugging him protectively, little scratches in both arms and few scattered mirrors in hair. Caelum's eyes widen from how his mother kept him protected.

"M-MAMA!" Caelum shouted as he called his mother. Tsuna slowly opened her eyes, seeing her son is there and safe made her smile, "C-Caelum, I'm glad you're safe."

"Mama" Caelum hugged his mother and she returned the hug.

"Tsunayuki-dono!" Basil called as he took out his hidden weapon which was his blade, observing outside.

Lancia's eyes narrowed as he noticed it too. "Enemy Famiglia."

Tsuna was shock to hear that as she hugged her son even more. If it was a famiglia that ambushed them, that would mean only one thing. Their life is in danger.

"Get out the car!" Lancia shouted as Basil went out first before Lancia and both Tsuna and Caelum are the last. Tsuna was shock to see many men were surrounding them, laughing as their guns were pointed to them. Tsuna pulled Caelum behind her.

Both Lancia and Basil took their stance, showing they will protect them. Caelum's eyes were open in shock, never seeing this kind of scenario in his entire life. He felt neither excitement nor fear, only danger.

"Looks like we cornered some important people." The one in front of them said, seems trying to mocked them, "The princess of the Vongola and her child, mind we use you as our hostage?"

Tsuna was trembling in fear but gathered her courage to fight her fear. She will never let anything happen to her son, not over her dead body.

Lancia gave a sigh, "It seems I can take all of you out seriously." Suddenly, Lancia was holding big chain connected to the dark big heavy spiky ball just beside him. It was his weapon, Steel Serpent Ball.

Storm Flame was soon attach to his weapon, and gave a power and quick swing, making everyone around them hit as they were all pushed and hit away. Tsuna and Caelum found it amazing to see they had a powerful escort with them who just wipe them out for a short time. Basil smiled, knowing he can do such thing before sensing something coming.

Tsuna's intuition reacted once again, "Lancia-san, Basil-kun the danger still hasn't vanished." Basil followed, "I can sense more coming."

"Tch, looks like we have no choice." Lancia walked forward, "Basil take her and her son away from here. Keep her safe and if you can request backup while I'll take their attention."

Basil was surprise before nodding, "Got it." Basil went to Tsuna and Caelum, "This way and hurry."

Tsuna turn to Lancia, "Be careful"

"I will" Lancia promised with a smirk.

Tsuna nodded before carrying her son and run away with Basil.

"Mama" Caelum called. Tsuna soothe her son, "It will be alright, I'll protect you Caelum."

That didn't convince him as he can weakly sense more were coming and chasing them. Basil point them to run left which she did as she turn left while Basil with Rain Flame to his blade quickly took out the coming enemies before following from behind.

'The place was unoccupied, no civilians around and it seems who ever famigilia they belong to, they had truly plan everything to corner us.' Basil thought as he observed his surroundings and attacked the hidden man from the narrowed street before running ahead to catch up with her.

"Basil it seems its dangerous ahead." Tsuna informed as she stop her run. Basil was bit surprise before asking, "Intuition Tsunayuki-dono?" Tsuna nod as an answer.

Basil looked around, "It seems we're truly trap." Basil gripped his weapon before turning into a certain building. "Can we hide inside the mall?"

"Wouldn't that be dangerous?" Tsuna asked. Basil thought for a moment, "True that it could corner us even more but it's better to have more hiding places than here. What do you say Tsunayuki-dono?"

Tsuna thought for a moment before nodding, agreeing as long as her son is safe. They decide to brake in the closed mall and search for a good place to hide.

'Reborn' Tsuna was calling mentally. She was terrified but she has to stay strong for her son, to keep him safe.

Caelum who can sense the fear of her mother decided to think of what he can do in this situation. He was never thought how to fight and his father told him we will when he turned eight, no fighting plan. No idea for strategy, asking help? Who? Wait… that's it!

Caelum took glance to her mother for a moment who was following Basil, he turn down to reach his mother's pocket, pulled the mobile phone and opened it.

"Caelum?" Tsuna questioned as she felt her mobile phone was taken from her pocket. Basil runs the stair and Tsuna followed. Caelum on the other hand went to the contact numbers when the first thing he found was his Uncle Natsu who happened to called recently. He pressed the call as the phone slowly progress before it began to ring.

Finding a right spot, Basil instructs them to stay there and so Tsuna did and put down Caelum to observe what her son was doing. She knew from the beginning that he will be different unlike normal kids would be. His intelligence was strong and when everyone asked about his mental capability, it was high like his father, instead panicking he will think a way to solve it.

Caelum was silent as Basil took a hiding place and took glance to Caelum who was waiting for someone to answer his call. Finally it answered.

"Hello Tsu-nee? Sorry I didn't answer immediately, just that-"

"Uncle Natsu" Caelum interrupted him.

"Caelum? What's wrong?" Natsu asked.

Tsuna took the phone from her son and put it to her ears, "Natsu-nii we-we need help."

This seems shock Natsu as he immediately turn serious, "What happen Tsu-nee?"

"W-we're being under attack." Tsuna informed as much as calm and clear voice as she can to make her twin brother understand the situation they were in. "I don't know which famiglia but… they trap us, we don't know what to do."

Tsuna heard the yell order of his brother to his men and Guardian from the phone, taking action as soon as possible.

"Who's with you?" Natsu asked her. She answered, "Basil-kun. Lancia-san kept fighting some men outside. I'm worried and… my intuition was yelling in my head, telling we're still in danger."

"Don't worry Tsu-nee, we may be far but I'm sure Giotto-nii could make it in time. Just hang on."

Natsu reassured before calling off the call. Tsuna gave a sigh of relief before giving it to her son and kissed his forehead.

"I hope they make it in time Caelum." Tsuna whispered to her son. Caelum looked up to see his mother's eye, seeing fear and hope. Caelum smiled, "Don't worry Mama, they will." He assured.

Basil smiled, "That's right Tsunayuki-dono and as long as I'm here, no one could hurt you."

"Thank you Caelum, Basil-kun"

I do not own Katekyo Hitman Reborn
