Chapter 10: Departure and Arrival

It's been month since Armino lived with them and more than months since he became Tsuna's friend. As time goes, Tsuna realized that more friends were gathering for him who he never expects to happen, Yamamoto Takeshi and Oniisan which was Sasagawa Ryohei, his crush Sasagawa Kyoko's older brother. They became a strange and loud group. Tsuna was really happy, glad that somehow he became friends with others. Looking back, he noticed something was off around Armino.

He's beginning to give distance around them, no, more like he rather watch them than join them. The way he watches them, Tsuna noticed three feelings, there were happiness, sadness and pain. Tsuna wanting to know the answer, not once he ever gave one. He kept saying 'I'm sorry', 'It's not time for you to know' and 'you'll understand someday'. Tsuna was always confuse, he wanted to help him but he won't let him, no matter how much he had done, he still can't break the barrier he had made to everyone around him.

Tsuna for this whole month noticed something change. Armino sometimes don't go to his room to study together which made Tsuna question on the sudden changes. Three or four days later, he'll come back and study with him and this time, question him on the lessons that he never gone through. Tsuna realized that he didn't came to his room like he usually does to study was because he was telling him not to depend too much from him. Thinking back, he was indeed depending on him. This made Tsuna learn how to study on his own so eagerly so he can prove to his friend who always helps him that he can stand on his own.

Tsuna noticed the changes and he was happy on his improvements which also made him happy. On their training, Armino as always never hold back his strength which still pains Tsuna. Even so, he was fine with that. He became stronger thanks to him but not once he ever uses his strength to someone else, even to his bullies. He doesn't want to hurt anyone which concerns Armino. In the end, Armino was the one who deals with them which not once Tsuna didn't able to save them while someone was almost killed because of it.

A memory was still fresh in Tsuna's mind. In the middle of the class election and one of his classmates which was also his bullies was talking bad about him. Tsuna didn't mind his insults and harsh words but both Armino and Yamamoto were. Yamamoto kept saying 'Enough' but not once he listened. Armino was giving a warning look which everyone around him noticed but he only ignored him. He's too much harsh and insult words snap Armino so hard that none ever expect to happen. He grabs his collar and drags him on the window and throws him away. The boy thought it's the end of his life but thankfully he still haven't fall, although his position was good enough for a great hard landing. The boy looked up and saw the terrifying look of Armino, still holding his collar and there was a silent message that he understands more than anyone and paled. The boy pleads to his life and Armino never listened. Everyone now took action as they want to save him but stunned on Armino's glare, he was truly angry and no one has courage to step in. Tsuna thankfully able to convince him to stop which he did but not in the gentle way that everyone would thought. He throws him in the wall instead and gave a warning voice before he return to his sits. That was the day where everyone finally feared Armino, he was handsome but hidden was terrifying demon that never fear tainting his hand in blood. They were all just thankful that the only one who can control his demon side was their Dame Tsuna which no one ever expected.

Tsuna shiver on that memory. After that day, the boy's mother gave a complain about what he had done but Armino able to fought well, even with violation he able to turn the case down and instead pass to him. The principal thought he would become a great lawyer but Armino didn't agree, he said that all he did was use the fact which he never got wrong. Tsuna was actually glad that Armino wasn't punish while he seems not minding it at all. Tsuna asked Armino never doing it again and he said he'll try but cannot make any promises.

Present time and night, Tsuna was trying to sleep but somehow can't. He sat up to his bed and sighs, he decide to take a quick drink and go to sleep. He slowly stood up and walked to his door. He opened the door and noticed a small light was coming to their dining room. Tsuna gave a questioning look, looking at the time, everyone should be asleep. He went down silently, not making noise and took a peek whoever was there. He was surprise that his mother, Nana was still awake and talking to Armino. Both seem serious on their discussion.

'What are they talking about?' Tsuna thought as he observed them.

"Tsuna you're still awake?" Armino questioned as he looked on where Tsuna was which made him almost jump in surprise. Nana looked to her son and gave a small smile, "T-Tsu-kun, should you be sleeping by now?"

"W-well… it seems I can't sleep for some reason and I wanted to have a drink but I never expect the two of you talking here." Tsuna reasoned which was true. "What about you two? What were you talking about and why are you two seems so serious?"

"W-well that's…" Nana was thinking how to say it to her son when Armino decide to tell it instead. "Tsuna the truth is…"

Tsuna kept quiet as he listened.

Italy, somewhere in the dark room, Vongola 9th, Timoteo was talking to someone who is small, like in the age of two years old. The baby figure was wearing black suit, fedora, and yellow pacifier. The baby has curly hair on the side and a chameleon on his finger, he seems petting it.

The Vongola 9th gave the information to the baby and spoke, "Here is Iemitsu's son who I choose to become next in line of Vongola. My friend, Reborn, can I trust you on this job?"

The baby who was named Reborn smirk, "Who do you think am I Vongola Nono? I'm the number one Hitman, I can perfectly do the job without failure."

Nono nod as Reborn took the paper about the new Vongola boss. He opened it and there was a picture of a teen brunet and honey eyes and seems weak. All his personal information were all there. Reborn narrowed his eyes for a bit before closing it.

"I'll take the job" Reborn said as he tilt down his fedora. Timoteo nod on his answer, "Your flight will be prepared within a week, is that fine with you Reborn?"

"Fine by me Nono"

Namimori Middle School and lunch time in the roof top

"EHHHHHHHHHHHHHHHHH!" Both Yamamoto and Ryohei shouted in union. "YOU'RE LEAVING!?"

Armino nod sadly. Just beside the door, Hibari Kyoya was heading to the roof top to bite someone to death when he heard the whole conversations which surprise him. On the roof top, the two still can't believe what they were hearing while Tsuna was quiet, truth to be told, he was still down after he heard he was leaving.

"He called me last night and told me I have this week left to stay here. After a week I have to return back to Italy." Armino reasoned. "So right now I'm saying it to everyone so all of you won't be shock when I suddenly announced I'll be gone or even disappeared out of nowhere."

"But why Caito? We always were having fun when you were around. You also tutored me, Tsuna and even Sempai now. Why so suddenly?" Yamamoto asked, sad that he'll be coming back home. Armino gave a small sigh, "I know but he pursue me to return back home. I don't know why so suddenly either but all I know is he wants me to return back. Sorry everyone, looks like I only have small time left to be with you."

"Do you know about this Sawada?" Ryohei asked to Tsuna.

"W-well… yeah… he just told me last night. Armi was talking to Kaasan, already informing her that he'll leave soon because of those circumstances." Tsuna said, making the two sad even more. Both looked back to Armino. "Are you truly leaving us?" Yamamoto asked.

Armino gave a small smile, "Just where are we anyway? In the middle of war era? Guys I may be gone back home but it doesn't mean we can no longer see each other again and much more meet again. Look, no matter how far we are, we're all friends. Distance has nothing to do with it, also, I'll try calling you guys too if you want to. I can send letters and even send picture on how good I'm doing. There's also a chance we can meet again."

"Really?" Ryohei asked. Armino nod, "Really. When I'm done on what kind of business had happened back home I'll come back here and enroll here again. We all can be together again. I promise." In his mind, 'If ever he summoned me again.'

Tsuna looked to his friend and step forward. He offer a pinky promise, "P-promise?" he asked, wanting to know if he will hold his word. He never made a true promise before so now in this very matter, he wanted to tell him he must truly do it. Armino was surprise at first but then smiled and took the pinky promise.

"Promise" Armino said, strong will that he will keep the promise.

Hibari on his place kept quiet for a while before leaving, no longer feel biting him to death.

Days go by and all they did was have time with Armino. Tsuna deep down was still in pain that he will soon leave but he made a promise which he knows he will keep it. They will meet again, no doubt about it. Tsuna can somehow finally see he's opening himself to them, especially to Yamamoto, Ryohei and this time, Hibari.

Every day for some reason, Hibari kept challenging Armino none stop while he didn't mind. Both fought without hesitation, even if they were already disturbing the other class and so forth, none able to stop the two. Tsuna as he watches them can somehow see Armino's seriousness, no enjoyments.

Talking to the girls which were Kyoko and Hana, not once Armino waver his coldness around them, as if he doesn't want to talk to them at all which was true. Tsuna tried to ask why and the only answer he receive was still as usual, 'Can't tell you, sorry Tsuna'. Kyoko sometimes ask him about him but he too doesn't know how to answer her question. Kyoko looks concern for him, he can't help but ask her.

"K-Kyoko-chan… do you happen to… you know… like him?" Tsuna asked, nervous on the question he had given.

Kyoko was bit surprise and shook her head, "N-no not like that Tsuna-kun, just that when I see his smile was like calming and refreshing. I feel like seeing him always smile and happy, especially with you but every time I talk to him… he kept giving me that cold look. I wonder why. I wonder if I did something bad to him."

"D-don't worry Kyoko-chan, I'm sure you didn't do anything bad. I'll try to talk to him okay" Tsuna said, making Kyoko happy.

"Thank you Tsuna-kun"

Training time, Tsuna asked Armino about his behavior around Kyoko.

"Why I'm cold around her huh… Tsuna, I did say I can't tell you didn't I, why are you still forcing me to answer it?" Armino asked. Tsuna looked down a bit, "W-well it's… because…"

"Was it because it was Kyoko who asked you?" Armino asked, making Tsuna blush, seems true. Armino chuckle a bit, "Your weird Tsuna… do you really want to know the answer?"

Tsuna nod, truly want to know. Armino huff before coming closer to his ears and whisper his answer.

"Perché in futuro, lei tradirà e ti abbandono, come tutto quello che aveva fatto a suo turno a nulla, ma le ceneri... Tsuna"

Tsuna was surprise. Armino took a step back and turn away. Tsuna on the other hand was speechless. Armino indeed answer him, finally... but...

"ARMI! I CAN'T UNDERSTAND ITALIAN LANGUAGE, TRANSLATE IT IN JAPANESE!" Tsuna shouted.

"Can't do Tsuna, I answered your question but you didn't tell me I should only speak Japanese. Find the translation on your own."

"ARMI!"

Armino was just laughing but inside was hurt.

On the final day of Armino's stay, they gave a farewell party for Armino in Tsuna's house. Yamamoto even brought Sushi for all of them since Armino turn to like them after eating their Sushi for the first time. Armino was happy, they able to surprise him so much which he able to enjoy. Tsuna was happy that Armino, his friend was enjoying himself with everyone.

"Armi" Tsuna called him. Armino looked to him with a smile. Tsuna smiled, "Armi well... I been saying this many times already but still... thank you"

Armino laugh a bit "Your really strange Tsuna, still I will take that thanks and as for me, I want you to have this." Armno gave a rectangular gift to Tsuna which surprise him. Armino speak, "This will help us communicate even we're afar Tsuna. Be sure to take care of it."

Tsuna took the box and slowly opened it. He was surprise it was a Laptop.

"A-Armi I-I can't take this!" Tsuna said but Armino shook his head, "You deserve it, beside your my friend so its fine if you ask me. I'm looking forward on chatting you and..." Armino added when he whispered to his ears, "It would be amazing if you learn how to hack in short time."

"A-ARMI! I can't HACK! Also, IT'S A CRIME!" Tsuna said while Armino just laugh to it.

Sicily, Italy, the bell from the church was ringing and the time seems to be sunset. The people there seems normal as many laugh as they walk and so forth. As they do they noticed someone walking, a small familiar fedora and black suits. The baby was heading on the bar. As he opened the door, two people were on the table, one was drinking while the other was drinking.

The one who was drinking spoke, "Reborn. Called out by the old man again?" the other spoke, "The popular once have it tough. Is it Rome? Venice?"

Reborn answered them, "It's Japan"

The two seems shock. "Japan!?" Both said in union.

The drinking one spoke, "The old man finally decided?"

"This one will probably be a long journey." Reborn said and in his mind, 'And the most interesting one'

Someone came behind Reborn, holding a knife and seems wanted to kill him. He tried to stab him but was only stop by a quick point of gun by Reborn's green gun.

Reborn spoke, "This isn't a toy." The man can't help but shiver as he drop the knife he was holding. The man became defeat and the green gun change into a chameleon. Reborn smirk as he walked away.

Next day, Tsuna woke up and quickly took a bath and dressed himself. Today is the day Armino will leave so he quick himself before running down to meet Armino but found only his mother.

"Oh Tsu-kun good morning. If you are searching for Armi-kun he went ahead, he said that he need to inform your principal about his leave." Nana said as she ready their breakfast.

Tsuna just nod and went to his sits. He looked on the side and saw Armino's things which was a backpack, he was ready to leave. He became sad, just thinking about his friend leaving still makes him feel that way.

"Tsu-kun" His mother called as he looked to her. She has a smile as she put the breakfast in front of him and spoke, "I know its sad to see one of your friend is leaving but there's nothing to worry, he did told you, no matter how far the two of you will be, you two will stay be friends."

"I know Kaasan... just that I finally get used of him being around and now everything won't be same as always." Tsuna said as he took his chopstick and said 'Itadakimas' before he start eating.

Nana smiled, knowing what her son mean, "You know Tsu-kun, I'm actually sad too that Armi-kun is leaving. He was such a good boy and fun to talk with. I love to see you two together, did you know that I already see both of you as siblings? He was like a big brother in the family... although there are times I feel it was a big sister but... hahaha. What am I saying?"

"Kaasan" Tsuna smiled, glad that his mother was trying to cheer him up.

"Tsu-kun, make sure when Armi-kun left, give him your warm open arms, like telling him he is still welcome to come back home, here in Namimori and we'll be all waiting for him, okay?"

Tsuna nod as the two continue to eat.

Class started and Armino was in front of everyone with their teacher.

"A-as you all heard, Caito will be leaving us starting today so this will be your last time seeing him. Caito, do you have any last words left for everyone?" The teacher said and asked. Armino nod before steeping forward.

Everyone seems relief that finally their demonic classmate was leaving. Seeing what they were thinking made him smirk.

"Our teacher said I'm leaving so this will be your last time seeing me. My last word from everyone is that this will be not our final meeting. I will be away for a while and even I don't know when I can return here in Japan but..." He looked to Yamamoto and to Tsuna. He smiled as he spoke more, "I will surely return since I made a promise. That's why everyone..." He gave his last evil smirk and eyes to everyone that made them all shiver in fear, "If ever I heard Tsuna was bullied by any single one of you then you already know who will hunt you right? Be sure to take care of him."

Many gulp in fear while Yamamoto laugh at it while Tsuna face palm but still smiled, 'Looks like in the end, Armi is still Armi' Tsuna thought as the teacher began to speak again.

Soon, everyone began their lesson as everyone were listening. Tsuna was now focusing while Yamamoto was trying to focus since his sleepiness was attacking him. Armino on the other hand was thinking something which thankfully none had noticed.

'The Rain and Sun will stay with the Sky...' Armino sighs inwardly, 'I really hate how things turn out during my stay here... but...' he looked on his side which was Tsuna who kept focusing and finally learn how to take notes. Armino smiled as he looked down which was his notes. They were all in Italian words and circle something in it. 'If the Sky is happy, I think I won't mind at all... now... after I leave, Tsuna... your adventure as a next Mafia boss is about to begin.'

The words he had encircle was an English word, more like a name. The word 'Reborn'. He's eyes were staring on the word, don't know if he should be happy or...

Armino scratch his head as he think about it. 'If only that future was possible to happen, maybe I can finally die happily'

After school, Tsuna, Yamamoto and Ryohei were keeping Armino accompany when someone was standing on the gate. There was Hibari, glaring at him.

"Yo Hibari, here to see him off?" Yamamoto asked happily. Tsuna shivered, 'Just what makes you think that Yamamoto!?'

"Of course he is in EXTREME, after all, Caito and Hibari are close to each other." Ryohei added, making Tsuna pale while Armino frown.

'Not you too Oniisan' Tsuna mentally yelled while Armino looked away, 'We're not friends Ryohei'

Hibari walked, heading in front of Armino. Armino stared coldly to him while Hibari glared at him. Both wedre releasing their intense fighting aura, making Tsuna suffocate on the atmosphere they were having. Even so, Tsuna noticed a little soft side of Armino when he was staring at him.

'Does he began to accept Hibari-san?' Tsuna thought as he stare on him.

It took a long minute of staring before Hibari spoke.

"Be sure to be back Herbivore, I will find you and bite you to death if you don't." Hibari said, seems to be his way of saying good bye. Armino narrowed his eyes a bit but answered him, "Just be sure to get stronger when I return or I'll make you lick the ground as your sign of defeat."

Hibari gave a smirk before walking away. Armino smirk back, looking forward for it.

Everyone soon walked away as they decide to take a walk around Namimori one last time before heading home.

Night at almost dinner time, Armino was on the couch and seems texting someone when he was interrupted by Nana.

"Armi-kun" Nana called. Armino turn around and smiled, "What is it Sawada-san?"

"Is that person e-mailed you?" Nana asked. Armino think for a minute before nodding. "He said my flight canceled this day so I'll be leaving before early sunrise."

"Is that so? Then you can still have one last dinner with us. So, how about we eat, food is ready"

Armino nod, "Sure"

Tsuna knowing his flight was delayed was happy a bit as he able to have more time with him. They used their time left to study how to use the Laptop Armino had given to him since he has no idea what to do. Armino found it funny at first but then helped him.

Nana from afar was really happy seeing them having fun, like siblings.

Late Night when Tsuna felt asleep on the table. Armino was just beside him and smiled, it seems Tsuna was now tired from playing his new Laptop around. Nana came and saw his son finally sleeping.

She sighs, "Tsu-kun, if you want to sleep then go to bed... silly child."

Armino chuckle a bit, "I'll carry him to his room Sawada-san."

She nod, "Thank you Armi-kun."

Armino nod as he slowly lift Tsuna's body, making sure he won't wake up and walked, heading to his room. When he arrived on his bed, he slowly put him down and put a blanket around him. Armino watch him sleep for a minute and silently laugh, to him, he sees a baby sleeping soundly.

'Is this how a Vongola Boss should be? For some reason i'm beginning to doubt it... still... you'll become a great boss in the future... you will...' He's eyes turn sad when he remembered what happened to him. He closed his eyes, as he was eager to change them.

He looked on the side on the table and surprise to him, there were pictures of Tsuna with his friends. Armino was also included there, smiling with Tsuna. Armino can't help but smile on the memories he had earn in his few days stay with him.

He looked back on the sleeping brunet and whispered, "Thank you for such a wonderful memories Tsuna... We'll meet again... surely... we will..."

Armino slowly went out the room and head back on the dining room. He sat on the chair and Nana gave his favorite drink, ice chocolate. Armino smiled as he took it.

"Thank you Sawada-san" Armino took a drink, really delicious.

"You just stayed here for more than months but it seems that it was already over a year Armi-kun" Nana said as she drink her tea. Armino nod, "I think so too Sawada-san, time sure flies."

"I agree with that... Armi-kun be sure to take care of yourself okay" Nana said, his tone was already in the mother tone. Armino was happy for it, "I will Sawada-san... Also, Sawada-san can I recommend something for Tsuna?" Nana gave a questioning look, "What is it?"

"I want Tsuna to have a home tutor" Armino said before he took a sip of his drink.

"Home Tutor? Why does he need one?"

"I think it can help him for his future that's all. Beside who ever that tutor will be, I'm sure Tsuna will become smart and a successful man in near future."

Nana smiled, "You really care for my Tsu-kun, like you see him as your little brother."

"Do I?" Armino was bit surprise as he looked down on his drink, seeing his reflection on the chocolate he was drinking. He smiled, "I might be Sawada-san. Since for me, Tsuna was like a baby child."

Nana smiled happily as she nod, "I knew you'll notice it. I'll do what you said Armi-kun. Home Tutor huh, I wonder where I could find one."

"You'll meet one Sawada-san... so early that you can never expect it would be."

Time where Sunrise was coming, Nana was already sleeping on the couch. She actually slept on the table but Armino carried her to the couch to have a better sleeping position and even put a blanket around her. He made a last note and left the house unnoticed.

The sky was still dark but surely, morning is coming. Armino adjust his backpack before walking away. He just kept walking until the sunshine finally came. Armino's thought was flying for a while until his phone vibrated. He took his phone and read the message. He smirk as he closed his phone and return it on his pocket.

'Finally' Armino thought as kept walking. Ahead, he can see a bus was coming on his way.

The bus just pass through him but looking on the slow motion, Armino and the familiar baby just cross their path. Inside the bus was a fedora child was riding, concentrating on his destination while outside, Armino continue walking, hidden on his eyes was staring at him.

Returning to normal motion, the bus gotten bit far away from him while Armino kept walking away from Namimori. Armino gave a final smirk before he truly disappeared on the road.
