Current timeline: Tsuna, Yamamoto, Gokudera, and Chrome in age of 24 while Hibari, Ryohei and Mukuro are on age of 25. Destroyed Arcobaleno Curse and currently on their adult form. Sawada Tsunayoshi the 10th boss was now had taken over the Vongola Famiglia, successful in turning back the Vongola's greatest glory, Vigilante Famiglia.

Reborn and Tsuna were on Tsuna's room, alone. Tsuna was trying to stop Reborn for a certain reason.

"I need to go Dame Tsuna." Reborn told him, trying to free himself from Vongola Decimo's arms.

Tsuna shook his head aggressively, not wanting to let him go. His hyper intuition was telling him NEVER EVER LET HIM GO.

"Why? Why do you have to leave? Can't you just stay?" Tsuna asked Reborn, desperate on never letting him go.

Reborn knew that and answered, "I have to Dame Tsuna, I have to."

Tsuna's tears soon came down to his eyes. He tightened his arms even more around Reborn's arms.

"If you wanted to quit being a hitman… then stay… JUST STAY WITH ME REBORN!" Tsuna cried in desperate.

That made Reborn stop for a moment, surprise on what he was hearing. After being froze, he started pushing him away again.

"Dame Tsuna I can't stay beside you." Reborn reasoned him.

"WHY? Please Reborn… please… don't… don't leave me!" Tsuna cried even more.

Reborn too doesn't want to leave but he has to do it.

"Why won't you let me go Dame Tsuna? Your already a boss, a successful and strong one, there's no need for me to be here with you. My job is done, you no longer need me." Reborn said.

Tsuna kept crying as he grip his arms even more, "B-but Reborn… I… I…" Tsuna was hesitating and Reborn was waiting for him to continue. Finally, Tsuna got a courage to say it out loud, "I LOVE YOU!"

Reborn was taken aback, seriously? Tsuna loved him?

Tsuna continued, "I love you so damn much that I don't want you to leave. You are like my everything Reborn. I don't care if you don't accept my feelings, all I want is for you to stay by my side, watch over me, torture me if you like, I JUST WANT YOU TO STAY WITH ME!" Tsuna looked up to see Reborn.

Reborn froze on the sudden confession. He doesn't know what to feel right now. He admitted to himself, he loved Tsuna. He had fallen in love to his Dame brunette Student which it's not supposed to happen but it did.

Reborn took the opportunity to free himself and quickly hug him. Tsuna was shock but then accepted the hug as he return it back and keep crying to his shoulder.

"Stay with me… please" Tsuna begged in cries to Reborn's ears.

Reborn hid his grip of his hands. He was showing pain, he doesn't like the way things happen. Reborn wanting to stay by his side but can't, wanting to return the love but can't, wanting to smell him but can't, wanting to feel his warm but can't and wanting… to see his orb eyes and face again... but can't.

"Dame Tsuna" Reborn called out softly which made Tsuna stop sobbing for a bit. Leon on Reborn's fedora slowly going to his master's arms, Reborn spoke, "Remember my name Dame Tsuna."

"Reborn?"

"Only you are permitted to know my name. You will not say my name to anyone, you will carry my name to your mind and heart until you die. Do you understand me… Tsuna?"

Tsuna was surprised, Reborn just called him without adding 'Dame' in his name. Tsuna nod, promising he will keep the name.

Reborn smiled from behind, "Only you Tsuna, no one else." Reborn then whisper his real name to Tsuna's ears which he found it surprising.

Reborn pulled out from the hug and gave a kiss. Tsuna happily returned back the kiss, liking how it feels but… something wasn't right. It's like… something was wrong to Reborn.

After they broke, Tsuna was about to ask what's wrong but something took him by surprise. Reborn's eyes, they were not black but gray.

"Re-Reborn… your eyes…" Tsuna was cut off by Reborn, "I Love You Tsuna… and… Good Bye."

Tsuna was about to react when something hit him from behind. It was Leon in his form of a stun gun. Slowly, Tsuna's consciousness was losing.

'Re… born'

Tsuna woke up from a dream, yes, he was dreaming about that day Reborn completely disappeared. It was already almost a year ever since his disappearance. Tsuna felt wetness on his cheeks, tears still coming out to his eyes. Tsuna took the pillow beside him and hug it tightly as he cry even more.

'Reborn… where are you?'

Soon Gokudera went in to his boss room, planning to wake him but what he saw was something that crushed his heart. His Juudaime was crying again. It's been like that ever since Reborn left them. They all tried to find the ex-Hitman but never found, like he had completely disappeared.

They all knew about their boss's feelings to the ex-Hitman, it was actually obvious for Tsuna but none knew about Reborn's. They all planned to keep it quiet, waiting for the day their boss would confess to him.

Everyone was thinking a happy ending for the two but turned out to be worst. Tsuna indeed able to confess, just to stop him from disappearing and Reborn accepted that feeling, even so he disappeared. He never showed any sign of coming back or presence on where he is.

They all done everything just to find him but nothing, even Shoichi, Gianinni and Spanner's technology were useless on finding the ex-Hitman. Even so, they still haven't given up. They kept searching for him until now, even if it was almost a year ever since he disappeared.

Gokudera who was thinking about their past operation cut off when he heard more sobbing from his boss. He decided to let him know his presence, because of his depression he became unaware of his surroundings, leaving him guard less wherever he goes.

"Good Morning Juudaime, it's time for breakfast." Gokudera said in soft tone but can't hide his sadness for his Juudaime.

Tsuna heard him and slowly turned around. Tears still coming out and decide to wipe them.

"I'll be going then."

"I'll be waiting outside Juudaime, take your time."

"Thank you Gokudera-kun."

Gokudera bowed down before leaving the room. Tsuna stared the ceiling for a minute before getting out the bed. He can't stop thinking about Reborn, not even ones.

Breakfast came and instead of loudness, it was quiet. No one can't give energy today, seeing their Sky, Tsuna depress once again, they all can't help but sad and worried for him. Yup, even Mukuro and Hibari.

Later, they all decide to give him a break on his paper work and let him have some fun. The Guardians tried making him happy which Tsuna was glad about. Even so, he can't stop being sad every time he thinks about him. They all knew but never gave up. They all decide to head to the beach, exclusive only for them. Tsuna and the others went to the car and head away. Lambo, Ryohei and Yamamoto were keeping Tsuna busy as they talk to each other. They wanted to let him forget about sad things, even if it's only a moment.

Soon, they were on the road where mountains surrounding the road. They chose the beach which was out of the city, a quiet place to say. As they go, Tsuna felt something. His hyper intuition was reacting. It was telling him to stop and head somewhere instead.

"Gokudera-kun stop the car." Tsuna immediately ordered.

"Juudaime?" Gokudera questioned. He was the one driving.

"Just stop the car!" Tsuna shouted which made Gokudera obligated and park on the side of the road.

Everyone were confuse on why until Tsuna suddenly went out the car and run. They all followed, leaving the car. They all kept following Tsuna as he was running heading up on the mountain where his hyper intuition reacting. He soon reached the top and surprised on what he had seen. The others finally caught up and surprised on what they had seen like Tsuna.

There on the near cliff were seven graveyard stone but no name imprinted. But there was a man lying like he was sleeping. The familiar fedora, suit and hair curl on the side. It was the lost ex-hitman they been searching for so long, Reborn.

Tsuna's tears came out, finally he found him. "Reborn!" Tsuna called out as he run heading to him.

As he got near to him and kneel down, something surprised Tsuna. Why does he smell awful like he hasn't taken a bath for more than months? Letting that slide for now, he touched his chin which surprised even more. He's cold, so cold.

"Reborn?" Tsuna called out again.

He twists him around, making him see everything on the Ex-Hitman.

"Reborn? It's me, Tsuna, wake up. Reborn? Reborn!" Tsuna tried shaking him to wake up but doesn't.

That's when the others went to him except Lambo, Mukuro, Chrome and Hibari. Ryohei checked on the ex-Hitman and surprised on what he had discovered.

"Sawada" Ryohei called, hesitating if he should tell him or not.

"What is it Oniisan? Is he okay? Will he get better?" Tsuna asked, not liking on how his Sun Guardian act.

Gokudera checked on him found out the Sun Guardian's hesitation, not liking it at all. He griped his hand, trying to hide the pain.

Ryohei began to tell him the truth, "Reborn is… dead… mostly almost a year ago."

Tsuna was shocked. 'No, that can't be. Reborn can't die, he can't! He's strong and number one Hitman, he can't die!'

"Tsuna" Yamamoto called which everyone turned on the swordsman. He pointed something which was not bit far from the ex-Hitman. It was Leon, also dead. His body was already colored brown, like a dried leaf.

Tsuna can no longer hold back as he cried even more and loudly.

They all have found the long lost ex-Hitman but no longer alive. The news soon spread, making those people who knew the ex-Hitman/Arcobaleno grief on his death. They all can't believe the news they had receive, until they had seen the body itself which confirms it.

They soon took a funeral, same place where they had found him. Not knowing who the other seven graves were, it must be some people that Reborn loved and choose to die with them. They all stayed quiet and pray for him, releasing their sadness on the death of their beloved friend, Hitman, comrade and so more.

The most one who broke out was Tsuna. He can't believe on what had happened. No one can also tell the reason of his death. There were no indication of wound, illness and so more. Then, how did he die? It was the only thing Tsuna wanted to know now. If ever someone was behind to all of that, he swore he'll kill that person.

After a week of his funeral, Tsuna was alone on his office, doing the same route line: paper works. He continued to study and sign them when he heard some kind of bell. He looked around, seeing no one. He decide to leave it be but then he heard another one.

Tsuna stood up, looking outside if there were people around but saw no one. He took a peek outside but saw no one. He closed the door and sigh, thinking it was his imagination. He turned around and walked back on his desk. When he got on the center, he heard another bell and that's when something strange came out underneath him.

It was a circle with strange writings around them. Tsuna who was about to get out on the circle when it produced too much brightness which made him cover his eyes. Soon when the light was gone, so was the circle and Tsuna.

Somewhere dark, eight 'THUDS' were heard on the room. It seems they were people.

"Ouch! ... Wha-what was that kora?" a certain person ask.

"Kora? Are you Colonnello?" Another voice asked.

"Wait, Fon?" A person named Colonnello asked.

"Ugh, what was that about?" A female voice asked.

"Lal are you alright?" Colonnello asked on someone near to him.

"Yeah, where the heck are we?" The female named Lal asked.

"C-can someone give some light?" A person terrified said.

Soon an orange flame flared out and all of them looked on the person who did it and it was Yuni, using the clear pacifier.

"Yuni?" Fon was surprised to see her.

Looking on everyone, it seems all of them were the ex-Arcobalenos, except Reborn.

"So it seems we're all here, united for some reason." Verde said as he pulls up his glasses to his eyes.

"Not only us." Viper said which became a questioned to everyone until finally noticing the last occupant. It was Tsuna, scratching his head from the hit.

"Sawada-san!" Yuni called surprise.

Tsuna saw them, confuse on what's going on. Later they all talked about what happened and made a conclusion.

"So in other words, all of us were sent here for unknown reason." Verde said, Fon added "Somewhere unknown as well."

"Guys, I found the door." Colonnello shouted which everyone followed.

The door shut tight as he kept pushing it in great force and finally opened. They were shock on what they had seen. They seemed to be in the large park, people were walking around, playing and so forth. They went out the room to see more of their surroundings and the room they were in. It seems to be the park's storage area. They scan their surroundings again.

"What's going on? More importantly, where are WE!?" The panic Skull asked.

They observed around once again and decided to asked some people. They were all speaking Italians, that only means they were still in Italy but somethings not right. Like many had changed.

They all kept walking around until something hit Colonnello.

"You got to be kidding me…" Colonnello whispered, pale. Colonnello quickly confirm if what he was thinking was true… it seems it did and became depress.

"What's wrong Colonnello?" Lal asked, strange for Colonnello to act this way.

Colonnello stayed quiet for a while before speaking, "Everyone… would you believe if I said we came back in time?"

They all found it questioning. "Mind clearing what you were trying to say Colonnello?" Verde demanded, wanting a clear answer.

Colonnello turned to them in terrified expression, "I said WE'RE BACK IN TIME!"

They stayed quiet until Skull shout in disbelief. Everyone was shock on the discovery.

"SEE? If I remember correctly, that fountain over there was no longer running water." Colonnello said as pointing the fountain then pointed on far away, "Then look, there's no towering building over there… See?"

"Now I think about it… that's true." Viper agreed.

'If this time was that time… that would mean… !' Colonnello run away which made everyone follow him. He kept running until he stopped and hid on the bushes.

"Hoy Colonnello what's-" Lal was cut when Colonnello signed her to be quiet, 'Shhh'.

He pointed someone and saw a stalker watching on the person who was sitting on the bench, reading a book. That person who was stalking was the little version of Colonnello. They all were astonished. That's what the teenager Colonnello looked like?

"Was that you Colonnello-sempai?" Skull question in disbelief. Colonnello grinned, "Handsome aren't I?"

"More importantly, what were you doing there?" Lal asked, irritated for some reason.

Colonnello sweat drop and looked away as he began to explain. "Y-you know, before meeting you I had met someone I had fallen in love with. She is that person over there." He pointed the person on the bench. "It wasn't just me who's completing with her but many more. She turns down every person that comes to her. Some were even beaten up. She's strong than you think."

They saw the person on the bench sighed. turned around to give a killing-intent glare which made the young Colonnello tremble in fear and run away. That person return to the book she was reading.

"I'm scared on her killing intent glare which gives me a hard time to talk to her." Colonnello continued to explain then face everyone, "But now I don't love her. I love Lal than her and I no longer care for her. Although there are times I wonder how she was doing."

"I think I had fallen for her." Skull said in redness on her cheek.

Tsuna who was silence until now felt something different as he looked closely on the person. The person sighs once again and stood up. That person turned around and walked heading on the group who was hiding.

"S-she found us!" Yuni whispered in bit scared, that person was releasing such strong dark energy around her.

That person looked on the group who was hiding and gave a glare.

"Would you people stop stalking me? It is really irritated every day." The person said and her voice seems… rough?

Skull immediately stood up and made his move to flirt the person, "Oh lovely maiden, I'm the great immortal-"

The person took his hand and immediately let him touch her chest. Skull seems confuse for some reason until the person spoke.

"I'm a man idiot." She… no, he said.

They were all shocked except Tsuna who was just staring at her-him. He threw his hand away and left them, not caring anymore.

"You fell in love with a man?" Lal deadpan asked to the frozen Colonnello. Fon checked Skull who was the same way and sigh.

Later, they were walking around town, finding a way how to return back to their present time.

"So, what do you plan to do?" Viper asked. Usually, he won't be tagging with them but in this situation in a different time line, they all can't split up.

"Tsuna are you alright?" Fon asked on the sad Tsunayoshi. He faced Fon and gave a small smile. "I'm fine Fon, sorry for making you worry."

"Don't worry Sawada-san, we can surely find a way to return back." Yuni reassured which made Tsuna smile a little more and nod.

Although Tsuna was actually thinking about the person whom they were stalking. 'Why do I feel I know him?'

Verde who was looking around pointed a certain place, "How about we stay over there and see what we can find."

Verde was pointing on the bar named Wing Ostaria (Wing Tavern). They all found it questioning but tried, they were all walking for more than hours, they need a place to rest for a while. The entire group went in and saw no costumer, maybe one who was sitting on the counter. That person had black hair and wearing red hat, black pants and black shirt, drinking some kind of alcohol.

"Welcome" The girl who was cleaning the glass wearing light blue blouse and apron greeted to the comers.

They all stayed quiet and went to their sits, on the corner on the right. The male came and asking for their orders. They all ordered food and few alcohol. The male waiter went away to get ready everything.

The Arcobaleno stayed quiet, waiting for their orders to arrive. They also noticed the girl was glancing on them. They kept watch over her, they can feel something off around her, except Tsuna who was still in deep of thought. Finally, Tsuna looked around on their surrounding until he landed on the girl who was drinking on the counter.

The girl who finally saw the brunette look her smirk, which makes them shiver as they prepare to fight if necessary, except Tsuna who felt something familiar around her.

"Mysteria stop scaring the costumer, they're new here." The girl who was getting ready on some orders said. The girl named Mysteria chuckled, "So you sense it Elaine."

The girl who was named Elaine sigh, "Geez Mysteria, can't you at very least control your suspicious look on people?"

Mysteria was staring at her for a minute before answering, "Your too dense, also idiot."

It hit her. She began trembling in rage, getting ready her knifes in her hands, like wanting to throw it to her now. Mysteria was just silently drinking, not caring on her hidden motive. She could easily dodge them after all.

The man finally came with foods and serves it to Tsuna and the others.

"Mysteria can you stop bullying my wife?" The waiter said scoffing.

Mysteria just sigh, "I'm just stating the fact Doranbolt so say it to her and not me." She drinks all her glass until its empty and raised it up. "Give me more."

Elaine slam her both hand in front of her, "Why don't you serve yourself! You're supposed to be helping us not playing like a costumer!"

Mysteria pretend she didn't hear it and made her glass point to her, silently telling her to refill it. Elaine released a 'Tch' and took her glass and began refilling it.

The man named Doranbolt was about to head out when Mysteria spoke.

"So, may I ask why the future Arcobaleno doing here?" Mysteria questioned which made everyone stop on what they were doing.

The Arcobaleno turned to her in suspicion. Tsuna became nervous on the atmosphere that was appearing to them.

"How do you know that?" The serious Viper asked.

Mysteria didn't answer, just glance on Elaine. She understood her glance and quickly refills her glass and gave it to her. She took it and drinks it.

"I'm the one who asked first, so you have no right to question me." Mysteria said, serious on how she speak.

Yuni observed her carefully before answering her, "We don't know, we were suddenly arrived here and we wanted to know our way back."

Mysteria observed her quietly before drinking once again.

"Now I think it's your turn to answer his question." Lal said serious.

"Simple," Mysteria began as she pointed Yuni. "The clear pacifier over there. Only Arcobaleno has that item. If you are going to ask why I know you were all from the future… let's say my sixth sense tells me that."

Before they could ask her again, Mysteria beat them. "I don't see you all complete, did someone split on your group? It's completely out balance."

"What do you mean?" Elaine asked.

"The guy that looked like a scientist was a Lighting Arcobaleno, the male hood was a Mist Arcobaleno, the one who answered my question was the Sky Arcobaleno, the Chinese man is a Storm Arcobaleno, the one who has a helmet on his side was a Cloud Arcobaleno and the Soldier like man was a Rain Arcobaleno. The girl beside him seems to become an incomplete Arcobaleno as well." Mysteria explained like no problem.

They all found it shocking that she knew about them.

"And the Brunette?" The man Doranbolt asked as he crossed his arms.

Mysteria observed the brunette for a moment before looking away. She pulled down her hat to hide her eyes from them. "A young mafia boss that holds the Sky Ring… Vongola Ring… right?"

Tsuna was shocked that she knew. She again drinks her glass like nothing happened.

"So the missing was Sun. Where is he?" Elaine asked them.

They all became silence and sad for some reason. Verde was the one who answered.

"He died."

Elaine and Doranbolt froze. Mysteria stopped drinking, wide eyes were hidden on her hat, shock for some reason. Tsuna noticed it, why?

"For real..." Doranbolt said in disbelief. Elaine asked them, demanding an answer. "N-no way… wait, HOW?"

"And why do you need to know?" Viper asked coldly.

Elaine was about to shout something but stopped by Mysteria.

"Mysteria!" Elaine shouted, silently asking her why she was stopping her.

Mysteria narrowed her eyes on the group before speaking, "I don't think even them knows his death. Let's keep things for now."

"Huh!? But Mysteria he's-" Doranbolt was cut by her, "He's coming so I want you to act normal."

Both married couple looked on each other and nodded, both return back to their work. Mysteria observed the Arcobaleno and gave a silent sign. She returned back drinking. They all found it weird when someone came in.

"I'm Home." the new comer greeted.

They turned on the new comer and saw it was the person from the park before. Mysteria turned around and smirked as she pulled down her hat and greet him back.

"Welcome back Reborn"

The Arcobaleno including Tsuna's eyes were beginning to widen as they heard the person's name.

EHHHHHHHH!

The person who had long hair, a face who looked like a woman and wearing yellow t-shirt, black sleeveless jacket and long pants nodded. It was the teenager Reborn.

I do not own Katekyo Hitman Reborn

My First Yaoi like Fanfic, hope you all like it.
