Ryuuichi stared as a black portal opened up beside him as he walked back from school. At first he thought that it was Vindice, but the portal doesn't have the same chill as Vindice's portal. He shifted his backpack and stepped into the portal. The portal, once Ryuuichi was all in, disappeared.

Ryuuichi blinked at the darkness, eyes adjusting to it. He looked around. Surely, he was in a void, again. He really doesn't know what was with voids and him. He was sure that the amount of times he had been in one was a bit unhealthy.

"Welcome, Shiroki-kun" He turned around, to see Kawahira sitting on a chair, sipping on what he presumed, a cup of tea. A white table with a tray of biscuits and another cup of tea was set at the opposite, in front of an empty chair. "Please, have a seat"

Ryuuichi did as told, placing his backpack down on the floor as he leaned back, neither looking nor touching anything on the table. He stared forward, at the bespectacled man. He, for some reason, wasn't a tad bit wary. He was simply curious, and he was observing. He didn't meet Kawahira in the future era, so this would be considered as his first time meeting him. 

Kawahira knew that Ryuuichi was watching his every move, observing with a great sense of curiosity. He didn't mind it and gestured the younger to the treats and tea he had prepared earlier. A small, calculating smile on his face. "Do try them and feel free to give a comment"

Ryuuichi finally looked at the biscuits and tea. 'So he made them..' He would be lying if he says that he wasn't surprised that Kawahira baked those biscuits, for the man looked like he wouldn't have the time to bake. Then again, it wasn't like Ryuuichi knew what he usually do anyway. "If you insist, thank you" He picked up one, a brown one, and took a bite.

"It's delicious" It really was. 

Kawahira's smile widen. "I'm glad" The smile dropped as Kawahira took his turn to observe Ryuuichi, an adult in a teen's body. It intrigued him, as he wasn't that knowledgeable on that term and field, reincarnation and souls anyway. That was one of the special species as he was, the one with cloud flame's forte. He never really understood that one, as whatever said would comes out a riddle or a mystery, something that he would never see nor understand. (Though, Sepira had once said that that one never spoke in riddles and personally, he believed knew that as well)

His stare burned, as though boring holes into Ryuuichi, but the younger didn't mind. Ryuuichi just simply continue eating the biscuit until he stopped. He took a sip of the slightly sweet tea before placing it down.

"How interesting" He raised an eyebrow at the man. 

"What is?" Kawahira chuckled with great amusement. "You don't seemed to be wary of me"

"Why should I?" Okay, now he's surprised. That was one of the answers he normally don't get. Even I-Pin was wary of him for the first time. Although he doesn't know of what Ryuuichi does of the results they would be getting out of what he had planned, Kawahira had half expected the younger to hate him for what he had done, and will still be doing until he passes.

"You should be aware that you're one of those in my list, no?" He noted that Ryuuichi's eyes flashed slightly. He knew well that he shouldn't be targeting the Historian, but to continue this for the sake of this miserable, pitiful world, he need to. Ryuuichi makes a powerful Cloud after all, or Sun as the matter of fact.

"Am I now. But even so, why should I be wary of you?" Ryuuichi put down the cup and looked directly into dark purple eyes. "The one I'm speaking to now is Kawahira-san, not Checkerface," He tilted his head. "Or am I not?"

Kawahira's eyes widen. His lips tugged up. "No, you're indeed talking to me" Ryuuichi replied with a smile of his own.

"Do pray tell though, what is the purpose of this," He struggled to find a suitable word. "Summoning..?" That sounded a bit as though the man had called upon a demon. Or something. He should stop, or his mind might wonder to another random thing.

"Right, of course. I need a favor from you, Shiroki-kun" He stayed silent as Kawahira continued. "At first I wanted to ask you of what you knew, but that will never happen. Could you please take over my place if I were to pass?"

Ryuuichi, for the first time since their conversation started, was speechless. From shock to confusion, to realization and lastly to anger. "No." He growled. "Don't get me wrong, I don't have anything against you, or anything you are suspecting of, but you'll not die. Maybe it's selfish of me to say this, but I'll not let you die."

"My existence won't bring any happiness but sorrow and anguish. What will it do good to you?" He shook his head.

"I don't know about that, and I don't know what it will bring me. But the fact you no on the face of this world dreads me. I never talked to you before, heck I never even met you before until now, but that still doesn't mean I'll let you die" He finds it hard to explain. He personally felt that Kawahira was one of the pillars that holds this world upright. It seemed as though the world would collapse if Kawahira were to, cease from existence. Perhaps because Kawahira was the last of the special species on Earth, but every inch of his body just couldn't take it well.

(If he didn't knew better, he might just as well suspect that Kawahira did something that made him feel like this)

"Everything has an anchor, and every anchor has a chain. You're as though the anchor to the boat, Kawahira-san. If you were gone, the boat would drift off and probably sink or something. And the Tri-Ni-Sette bearers are the chain that holds you. You understand that, no?"

Kawahira hummed. He knew that very well. The Tri-Ni-Sette was made for the sake of the world's balance, after all. The Arcobaleno are his job, his to find, his to toy, and his to finish. He have half the mind to just let this corrupted world rot without the Arcobaleno, without him, but something held him from doing it. Sepira, probably. He wasn't going to deny that he enjoy toying with the Arcobaleno, of every generation, but he does get sick of it sometimes. He knew, this small sacrifice, the sacrifice of those chosen as the Arcobaleno, was obligatory, to prevent a larger chaos.

It didn't, however, stop him from hating himself for ruining their lives.

"Everyone dies in the end, Ryuuichi-kun" The said teen paid no heed to the sudden change and stood firm on his point. "I know. But it's not your time to go yet"

The older smiled at that, genuinely amused at how logic seems to wrap around Ryuuichi like a second skin, how he sounded so reassuring. 'His charm, perhaps' "And if this is what you've called me here for, I'm going to punch you, Kawahira-san" The smile that was given to him shouldn't scream I-Know-What-You're-Thinking, but it did. 

-----------------------------------------------------

"Ryuuichi" Ryuuichi choked on the rice ball and all but flailed his hands around for his water bottle. When he managed to grab it, he practically ripped the cap open and gulped down the water in haste. He coughed and glared at an amused Reborn with resign. "Don't do that anymore" Sadly, he knew very well that he will be scared like this again. He seriously don't get what was so fun about scaring him by popping out of nowhere.

He blame that on Giotto and his merry sets of friends. 

"Come over after school." He blinked at that once. Yuuichi has training as usual, and something about the devil coach of theirs planned to drive them to the seventh hell or whatever, he wasn't exactly listening. It probably would be fine. Besides, he kind of knew what Reborn wanted to talk about, but it would be better for him to confirm it. And he wanted to mess with Dino a bit. (He found it quite amusing)

He shrugged. "Sure" Reborn grinned almost too creepily to the point Ryuuichi wanted to shake the hitman.

------------------------------------------------------ 

"To dispel my curse, I want you guys to fight in my place" Tsuna honestly couldn't believe whatever he had heard from Reborn. It was illogical to an extend, but his life was never logical when it comes to Reborn. But the man Reborn had said, the Man with the Iron Hat, he sounded like a conman, but Tsuna doesn't know, for he had never met him before. 

Secondly, he couldn't understand why was Ryuuichi called in as well. He understand that he and Dino was asked as they are Reborn's students, but Ryuuichi, of all people, wasn't. For all he knew, Reborn wanted to unravel Ryuuichi's secret while Ryuuichi was simply amusing Reborn, or at least that's was what he saw from their interaction.

He watched Ryuuichi, who sat on the floor in front of Dino with an indifferent face through the corner of his eyes. "No, I got that part, but.." He turned back to Reborn when Dino spoke up.

"What will it be?" Of course, Tsuna already knew what their answers would be. Reborn had helped them, guided them past the dark moments and taught them. Helping him is something that they definitely will do. Not because they owe him, but because they care about Reborn as how the hitman had cared for them. At least, that's what Tsuna felt.

Dino was the same as Tsuna, no doubt. He will definitely do it. But for Ryuuichi to do this, it was unsettling enough. This representative thing would be very dangerous. He knew that Ryuuichi understood that as well. 

"Well, that's weird. A request from you. I'll help you" 

"If Dino-san's my ally, I'm not scared either. It's fine for me" Reborn nodded at that, and he along with his two students turned to the silent teen, waiting for his answer.

Ryuuichi scrunched his nose at the possibility of fighting Vindice if he were to join Reborn. And if the Vindice decided to attack him right in front of Yuuichi, he might as well slaughter them for Tsuna instead. He wasn't worried of the beginning of this fight, but hell Vindice. Goddamn Vindice. 

That aside, he does wanted to help. Really. He didn't know how would he be able to help, but he would just have to see, wouldn't he? 

"I'm in. Though, I won't guarantee that I'll be doing anything" He looked directly into Reborn pitch black eyes, seeing a glint in it. Nonetheless, the hitman was satisfied. 

"I see. Thank you" Reborn was visibly very delighted of their answers, but honestly, that smile on his face just doesn't feel right. "That's good, that's good. Three representatives get. Good. I'm gonna have dinner" 

Ryuuichi outright shook his head in exasperation as Tsuna and Dino asked (demanded) Reborn to explain the most important point. He personally felt that Reborn's answer wasn't exactly it, then again, he was right. The Arcobaleno, after cursed, all had their appearance changed. That was one, and the other one...

Well, he just have to remember to take picture of the Arcobaleno in their adult form.

He bit his lips and leaned back, onto Dino's leg. He ignored the jolt from the blonde man and sighed. He mentally listed the other Arcobaleno's representatives and frowned. When he thought that he would be worried about Hibari, since he was the only one, he found himself more worried of the Shimon, Skull especially. And then there's Kawahira. 

"Ryuuichi..?" He peered up to see the blonde looking at him with concern, mildly aware that Tsuna was too. He shook his head, looking away and huffed. "Nothing." He yelped when a hand ruffled his hair, immediately tried to swept it away. 

"Don't be too stubborn. If there's something wrong, tell us, alright?" He pouted at that but relaxed. For some reason, Dino's tone had his nerves settled slightly. 'The Sky's perks, huh' He tilted his head to Tsuna, who was staring at them. He, without thinking much, reached out to the brunette's hand and tugged him down. 

"Uwaa!" 

Dino stifled a laugh when Ryuuichi settled Tsuna on his lap, squeezing the daylight out of the brunette. Tsuna squeaked when Ryuuichi grunt vibrated from his shoulder. It lasted not more than a minute before Ryuuichi's grip loosen, letting go of Tsuna with a quirk smile. 

"Do what you deem best, Banchou~"

"I'm not a Banchou, Ryuuichi!!"

-----------------------------------------------------

Sakura silently and carefully walked to her sons' room. She peeked into Yuuichi's first, smiling softly upon seeing her youngest son sleeping soundly without a care of the world, her innocent son. She slowly closed the door with a soft, audible click. She then toed to Ryuuichi's room, only to see light from the bottom of the door. Frowning, she knocked.

When there was no reply and Ryuuichi didn't open the door for almost a minute, she twisted open the door. She was surprised when she saw Ryuuichi, with his headphone on, writing something on his notebook. She shook her head when he didn't notice her.

"Ryuu-kun" She walked to him and placed a hand on his shoulder.

Ryuuichi jumped in surprise, almost yelping in surprise and whipped his head to his mother, raising a brow at her. "Mother?" He took off his headphone and fully turned to her. "Is there anything you need?" 

Sakura huffed, placing a hand on her hip. "What time do you think it is now, young man?" He winced at her chiding voice. "Err.." He sheepishly scratched his cheek. "Eleven..?"

"One" Ryuuichi blinked, looking at the digital clock. It was really one in the morning, and he didn't realize. He nervously laughed. "Opps..?"

She sighed in exasperation. She pointedly peered at the notebook. "What are you doing?" Her son looked at his notebook as well and made a noise. "Oh.. Umm.. Notes...?" He slowly said. It was partially true anyway, expect that it wasn't school notes. It was notes on the representative battle. He was just trying to refresh his memories. It was already very surprising that he managed to remember that much for almost 14 years. 

He sweated under her hawk-like gaze that was boring holes on him. He purposely not looking at her for the fear she notice something. He all but jerked when she sighed again. "Be careful at whatever you're planning to do, Ryuu-kun" He finally looked at her, eyes wide.

"What-"

"Oh I know there's something going on. Boss was too suspicious" Her tone of resignation made him frowned. She was worry, wasn't she? After knowing that he was involved in the mafia. When she and his father returned a week before Dino arrived, he had somehow suspected that they knew that he would be involved in whatever Dino was involved in along with the Vongola Decimo.

He bit into his inner cheeks and breathed out, not realizing he was holding his breathe. "Yeah.. I'll be careful" He gave her a loop-sided smile. She returned a small smile of her own, before she engulfed him into an embrace. "Remember that we're all by your side, alright?" 

Ryuuichi stiffly nodded, wrapping his arms around her as well. He felt slightly awkward, but he melted into her arms easily, feeling absolutely happy and warm. "I always will"

Outside his room, Kei leaned against the wall with his arms crossed. His head rested against the wall, looking up at the ceiling. He had followed Sakura to look at their sons, but he didn't went into Ryuuichi's room. Sakura needed this, heck even Ryuuichi needed this moment. Ever since that incident, ever since they had came back, Ryuuichi was awkward around them, looking as though he had something to say but didn't know how. 

His wife, on the other hand, was constantly worried because the fact that Ryuuichi knew of the mafia, and actually is a part of it puts Ryuuichi in a dangerous position. The deeper one was involved in the dark world, the easier it would be to be targeted and killed. She was worried about Yuuichi as well, but since their youngest son still knows nothing of it, he's safe from the chain of Omerta and the risk of being targeted was lower. 

Still, nonetheless, she couldn't stop worrying about them. Kei himself was worried as well. Why wouldn't he? Ryuuichi and Yuuichi are his son, his pride and joy. They're his, theirs' precious. 

Now that Kei thought about it, they had never stop worrying about their son, had they? They've been worrying about them ever since their just babies and will continue on worrying until they're gone. He chuckled when a memory of Ryuuichi and Yuuichi, both still toddlers, running around him as they played pretend. 

A slightly sad smile tugged on his lips, but there was happiness in his eyes. They grew up so fast, became independent so quickly, slowly becoming men of their own. They rarely depended on them anymore. (Like they depended on them that much anyway) And Kei somehow wished that they will.

He noticed that his older son shoulders and worries of a lot, even more after that incident by the way his son's stiff frame that can't seem to relax. Yuuichi as well, but it was concern towards Ryuuichi. But no matter how, he noticed as well that they would never tell them. If he was any other parents, he would think that they're in the 'teenage' phase of keeping secrets and all, but he wasn't. 

True, Ryuuichi kept a lot of secrets from them, Yuuichi as well, but he, and Sakura, knew very well that they didn't tell them to avoid making them worry even more since they knew that they were busy. (Though, the twins body language and way of speech would be a huge giveaway, most of the time)

He heaved an inaudible sigh, praying to whatever deity up there to watch over his sons, for their safety. His hands clenched into fists. He looked towards Sakura, who closed the door and returned her a somber smile when she gave him hers. He reached out and pulled her into a sideway hug, kissing her on the forehead before they both walked to their room. 

Apparently, Sakura had the same thoughts as his.

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

A/N= First chapter of the Curse of Rainbow Arc!! Urrhh.. I skipped quite a lot of things... This would be chapter 347-356. Next chapter starts off from 357.

I noticed that I tend to write about those once-antagonist... Not so antagonist-like. For at least once... I've no freaking idea why I did that, but I did.

On Kawahira, it was mentioned that Ryuuichi would be a powerful cloud or sun, was because the Sky was Tsuna. Even though Ryuuichi's main attribute was Sky, his offensive and power mostly lies on Cloud.

Banchou meant Gang Leader, as of how Tsuna would be the boss of their team. Ryuuichi found it amusing.

Note, Ryuuichi was always an awkward child, but he became more awkward after knowing the truth from Sakura and Kei.

Fun Fact= Yuuichi wasn't exactly sleeping.

Sakura and Kei didn't exactly have a lot of appearance, so yeah. 

I'm getting sh-ittier at this...
