Prologue – The Parental Sky

When Sawada Tsunayoshi was thirteen, if you asked him if he would like to have kids, he would have said yes and start daydreaming of the person he liked at the time, Sasagawa Kyoko.

When he was fourteen, if you asked him if he would like to have kids, Tsuna still would have said yes, and smiled inwardly as the Sawada household took in three children of varying ages, despite how rowdy they got sometimes.

When Tsuna was fifteen, if you asked him if he would like to have kids, he would have said no, as he realized that unless something of miraculous odds happened, he would not wish for his kids to grow up in the mafia. The experiences he had, Varia, Millefiore, Shimon, and Vendice, had only served to strengthen this wish to not have kids, unless he could escape his duties as Neo Vongola Primo. He did cherish the time with Lambo, Fuuta and I-pin though.

When Tsuna was sixteen, if you asked him if he would like to have kids, he would have stared wide eyed, face flushed, embarrassed and would not have said a thing. Because at sixteen, Tsuna's crush on Sasagawa Kyoko had faded, and instead began to secretly obsess over a certain Disciplinary Committee Chairman. Reborn had definitely been disappointed in him for that.

When Tsuna was seventeen, if you asked him if he would like to have kids, he would have said yes, but also state that it wouldn't be possible. He would then stare longingly at one Hibari Kyouya, since he had confessed to the other after weeks of helping Hibari in his office and providing him with lunch. A confession that was accepted. Note that Gokudera Hayato and Yamamoto Takeshi had confessed to each other by then as well.

When Tsuna was eighteen and finally inherited Vongola, if you asked him if he would like to have kids, he would have said yes, but mention that right now, it wasn't the time. He did have paperwork to clear in wake of his inheritance ceremony, but Kyouya was helping him manage on that end (When he wasn't fighting Mukuro of course.).

When Tsuna was twenty, if you asked him if he would like to have kids, he would have just stared into the air dreamily. A few days before little Yuni had come forward with a vision of the future, a vision of Tsuna holding a little baby with hair as fluffy as his was. Now, the only one who could snap the man out was Kyouya, who would tell him that it wasn't possible unless one of their scientists came up a reversible way of allowing a male to get pregnant.

When Tsuna was twenty-one, if you asked him if he would like to have kids, he, or should we say, she, would look at her belly and rub it gently. Only two months after Yuni gave her vision, Byakuran had come to the Vongola mansion and offered to swap Tsuna's body with that of an alternate female version of himself. Tsuna, who had been longing for kids to care for ever since Lambo and I-pin were old enough to go to school, had almost accepted it immediately. However, Hayato volunteered to test if the method was a viable one. A month later, a rather irate and pregnant female Hayato stormed into the Millefiore base, went straight to the room that kept the marshmallow supply, and bombed said room. Byakuran cried for weeks. Seven months later, Hayato declared the method as safe enough if all she had to endure was being female for nine months. A body swap and a week later, Tsuna was declared pregnant.

When Tsuna was twenty-two, if you asked him if he would like to have kids, he would smile and point to a blue eyed, fluffy haired, brunette baby sleeping on the dozing Kyouya's chest. The child, was named Sora, after the Sky his mother represented. Hayato and Takeshi's child had been named Riku, after the Earth element that their leader's closest ally wielded. The boy had the same silver hair and green eyes as his mother did (Hayato glared at anyone who dared call him that. Takeshi was the only exception.). Kozato Enma was touched by the gesture.

When Tsuna was twenty-three, Sora, one, and Riku, two, Tsuna decided to leave the Vongola in the hands of Xanxus, if only for the six to get away from the mafia and spend time as a family. They left for a set of islands owned by the Vongola, known as Destiny Islands, and settled down, the mayor welcoming them. Though, Byakuran warned them that the islands stood between reality and nothingness, sometimes bridging dimensions, and thus, strange animals and beliefs were common. Even then, Millefiore, Gilgo Nero, Shimon and members of Vongola often visited.

When Tsuna was twenty-six, he had looked on with narrowed eyes at the two strange visitors that had come within days of each other, both oddly dressed and wielding key shaped weapons. He kept quiet when he saw the two interact with the kids though. Weeks later, as stars began to fall from the sky, Sora had come home talking about letting someone sleep within his heart, someone he had helped, even before he was born. Tsuna just hoped the person Sora just helped would not cause problems in the future.

When Tsuna was twenty-eight, he found Sora crying over something that his intuition told him had to do with Riku. He was honestly finding it odd though. Riku was very possessive of Sora, and would never try to hurt him. Then again, he guessed it was just Riku wanting Sora's attention. It amused him really. Kyouya, when he came back from checking Namimori, decided to threaten the silver haired boy, but the boy just didn't care, completely focused on Sora. Even Hayato's reprimands didn't help.

When Tsuna was thirty-six and Sora was fourteen, as time drew near for Sora to be trained in using Flames, Tsuna felt something happen. Something had changed within the islands, and his intuition was screaming at him that Sora was going to be in the center of it all. That night, he felt himself black out, only to find himself back in the Namimori Vongola base. He hurried to the monitor that watched over Destiny Islands, only to begin wailing in fear and worry for the safety of his son. The cameras at Destiny Islands had lost its feed, and its existence, wiped from the map.

Kyouya had heard his cries and had dashed into the room to hold him. Hayato, having arrived in the same manner as Tsuna, sobbed while clutching his leader, the both having lost their sons. Takeshi then gave Hayato a hug while letting the other cry.

By the side, having come in just minutes ago, Kawahira looked on sadly yet knowingly, realizing just what had occurred to Destiny Islands. The man then decided it was best to inform the holders of the Tri-Ni-Sette just what they were truly holding. When all 21 were gathered in the right location, it would reveal the heart of their world, and the door that had been at Destiny Islands, was a dimensional rift that had been sealed tight. Until today that is.

Tsuna returned to his duties as Neo Vongola Primo, but it was never the same. Every night, he had cried himself to sleep, wondering and worrying for Sora, wishing he had at least taught the boy how to use his flames. Kyouya would just let him cry, knowing it was never good for the other to bottle his emotions.

Two years later, Byakuran came into the base and informed them, "One of my alternates saw Sora." Tsuna had cried with relief, but then the Millefiore boss had more to inform him, "He'll be returning soon. He's just looking for Riku right now." Then it was Hayato's turn to cry, knowing that his own son was safe. Almost a month later, Tsuna felt the urge to return to the Islands, which had turned up a year after its disappearance. The four parents left, trusting Tsuna's intuition that their sons, were finally returning home. And they did, in the form of shooting stars.

When Sora first returned home after two long years, Tsuna had fussed over him, making sure that nothing had caused him harm. It was only later that he realised how much his son – his and Kyouya's son - had grown.

First was the friends he had made. Donald acted like the typical storm, hot headed, reckless and loyal. Goofy, with his high defensive capabilities, took the position of the lightning.

And Riku... After all those years as childhood friends, it took one act of betrayal of their friendship for the two to finally get together. Tsuna saw it coming. After all, Riku had obsessed over Sora whenever the boy came over to their house. He was happy for the two. Riku, he was both the deceiving mist and aloof cloud.

Second was the fact that his son had begun his journey as a Sky. As a forgiving, accepting, all encompassing sky. Listening to Sora's stories, Tsuna was amazed by the colourful people he had become friends with, both good and bad. It reminded Tsuna of himself.

Lastly, was one fact that Tsuna really did not want to acknowledge. The fact that Sora, when fighting, inherited from his other father his battle instincts. The boy had been jumpy ever since he came back. More aware of his surroundings. Tsuna hated that his son had lost his innocence.

Honestly though, it made him happy. His growth as an individual had earned him a right to learn how to use his Flames. When he was fourteen, Sora had been too reckless, too unprepared for the responsibility that came with being the Sky. Tsuna, despite having wanted to teach him, decided to leave that part of Sora's heritage till he matured a little more. Now though, he had experienced the world. He had already unknowingly gathered some of his guardians, even if the two anthropomorphic animals had obligations to another leader.

Thinking about it, Tsuna thought maybe it was time to begin Sora's training of his Flames. Sora had, after all, grown up with time-travellers, dimension hoppers and magic like abilities. His travels just added on to that experience and would help him continue to grow as a Sky. He didn't need training in leadership. Just how to do paperwork (The boy missed two years of school!) and how to use his flames.

After all, Sora, was an all encompassing Sky.

I AM SORRY!

Ah snap, this chapter came totally out of nowhere. It was half done a few weeks ago, but all of the sudden I had the urge to complete it today. And this is on top all my other fanfics! I'm a terrible author... I... I... *Crying uncontrollably*

I really think all the readers for my other fics are going to kill me for this. I have ideas and chapter summaries for this fic ready, since said ideas came up during February (When I completed KH3D for the first time.). So right now... is just making sure I post new chapters for all my fics at one go. I'm really disappointed in myself...

(If any of you read the above, don't worry, I'll stop the whining...)

Anyways, this fic is a KHR/HP crossover. One that portrays certain KHR characters as the parents of our KH main casts. Yes, I'm ignoring the fact that Sora's mom was calling for Sora during KH I. She never appeared again so her existence to me was... questionable. Main reason for this fic was Sora's fluffy brown hair, and the fan idea that Giotto had blue eyes, thus Sora inheriting the blue eyes. Riku was easier since Gokudera has silver hair and sea-green eyes. So, a Different Parents fanfic was born! I think this is actually the first of its kind in the KH/KHR crossover section, so, YAY!

Please review and tell me how this chapter was and what I need to change. It'll make me really happy!
