"Hey Fon."
"What is it, Reborn?"
"Promise me your first child."
"Okay? But why would you—"
"The contract is sealed."
"What."
-o-
In a world where there are people who are born with magic, it's kind of obvious that certain types of magic would be frowned down upon. Perhaps it was because they were naturally destructive, or perhaps there was this one asshole with that magic who tried to take over the world, prejudices are still alive and thriving.
Sawada Tsunayoshi was born with dark magic.
It was because of this fact that he didn't really have many friends, and what little friends he had tended to be kind of… shady. For one, he was pretty sure Gokudera wasn't one hundred percent human like he kept insisting he was. Also, Yamamoto was probably a cold-blooded murderer in disguise. The shadiest one of them all, however, had to be Hibari Miyu.
As a name, Miyu was written with the kanji of "truth" and "gentleness". Hibari Miyu's personality could not be further away from her name. She was a compulsive liar and had the tendency to beat up people who mildly annoyed her. She was motivated by impulse and self-gain, and she usually was impossible to find. Still, she was Tsuna's friend and was always, always there for him when he needed her.
One day, Miyu approached Tsuna with a smile on her face. Upon seeing it, Tsuna wanted to run. However, Tsuna was, by nature, a nice person and hence was rooted to the spot as Miyu slowly strode towards him. He could hear a funeral march in his head.
"Tsunayoshi," Miyu drawled out. "If I die, will you take care of any of my possible children?"
"Um." Tsuna said. Miyu glared at him and he cleared his throat. "Won't the custody of your child go to a family member in your clan?"
"Yeah it would, but I don't want it to be. You see, the person most likely to have the custody of my child is my uncle, Fon, and as genial as he may be, a dirty sock would be a better parent to my possible child. He also has a bounty on his head, being of the Arcobaleno and the strongest martial artist in the world."
"I really doubt I'm much better," Tsuna countered.
"Yeah, but you're a witch! I can promise my firstborn child to you and, as far as magic contracts go, the firstborn child contract is recognized by custodial law. You will help me, won't you?" Miyu smiled at Tsuna and Tsuna knew it wasn't a request.
"Alright," Tsuna conceded. What were the chances of Miyu having a child?
"I, Hibari Miyu, promise to give Sawada Tsunayoshi my firstborn child if I die," Miyu said smugly. "The contract is sealed."
And then she proceeded to disappear for twelve months. Twelve months in which Tsuna put the strange encounter out of his mind.
The next time Sawada Tsunayoshi saw Hibari Miyu, it would be at her funeral.

"The child is yours now," the clan head told Fon as she handed the baby to the man.
"Er…" Fon said as he stared down at the fragile little child in his arms. The child yawned and stared back at Fon with steely grey eyes.
Fon had no idea how to take care of a child.
Suddenly, all the lights in the house flickered once, twice, and extinguished. The sky turned dark and cloudy and an unnatural breeze whistled through the hallways. Both Fon and the Hibari clan head froze, recognizing the signs.
This was dark magic.
The shadows writhed and stretched across the room, inky darkness coalescing to form a humanoid figure. The clan head narrowed her eyes, getting ready for a fight. Could this thing be the one who killed Miyu? Was it back to kill her son?
The shadows fell away to reveal a hooded figure. The figure turned to see Fon. Fon with the baby in his hands.
"You're kidding me."
-o-
"So you're not an evil witch looking to kill Miyu's firstborn child and finish what you've started?"
"No! I didn't even kill Miyu! She's my friend," Tsuna denied vehemently. "Miyu just promised her firstborn child to me because she didn't want her uncle to take care of the kid because…" Tsuna trailed off when he realised that said uncle was in the room with him. "…because of reasons."
Fon stared at him in question. Thankfully, the clan head seemed to understand what Tsuna was saying and nodded in agreement.
"Miyu had always been particularly resourceful."
There was a bright flash of light, the particular kind that made Tsuna's head hurt really badly, before a low baritone voice said, "Fon, what the hell."
Tsuna turned to see a tall figure in a black suit and fedora. Tsuna knew who this person was. Everyone knew who this person was.
Reborn of the Arcobaleno, the strongest fairy in the world.
"Oh my god."
-o-
"So, Fon, you promised your first child to Reborn. And Miyu promised her firstborn child to Sawada," the clan head clarified. All three of them nodded, making her sigh deeply.
"There's only one way this can turn out. Both Reborn and Sawada has to have joint custody of the child."
Tsuna unconsciously tightened his grasp on the child in his arms. It caused the baby to make a noise of annoyance and Tsuna immediately loosened his grip and apologized. The baby made another noise, a more pleased one this time, at Tsuna's apology. There was no doubt that this boy was Miyu's child.
"What's his name?" Tsuna asked, changing the subject. The clan head shrugged. Tsuna looked at Fon. He shrugged too. Tsuna looked down at the baby. The baby looked back at Tsuna. "Kyoya?" Tsuna suggested on a whim. The baby made a noise that Tsuna took as acceptance.
"Hibari Kyoya it is," Reborn said, making Tsuna jump. Tsuna had forgotten he was there.
"Um," Tsuna began. He didn't get a chance to continue for Reborn had stood up, pulling Tsuna up along with him. Reborn's arm was around Tsuna's waist, making him flush red.
"Tsunayoshi and I will be taking our leave now," Reborn said and then they were gone in a flash of light.
-o-
They arrived in a nice little cottage in the woods. It had quite a homely feel, but Tsuna would probably be able to appreciate it better if he didn't feel like throwing up.
Shoving the baby into Reborn's arms, Tsuna rushed out of the door and started to dry heave. He had been suspicions but this confirmed it. Reborn's magic was predominantly light. Dark magic was weak to light magic.
Raising Kyoya with Reborn was going to be difficult, in more ways than one.
-o-
"So, dark magic?" Reborn guessed when Tsuna reentered the cottage. Tsuna nodded and then got distracted by Kyoya.
"Reborn, that's not the way to hold a baby," Tsuna said and quickly took Kyoya away from Reborn. A normal baby would be crying but Kyoya was just glaring at Reborn. He was truly his mother's child. That being said, it was a little worrying. Were children supposed to be that quiet?
"What do babies eat, anyway? Reborn asked.
"Um, milk? I think…" Tsuna trailed off, unsure. They stared at each other, finally realizing what kind of situation they had gotten themselves in: stuck with a baby and a total stranger, and with absolutely no idea what to do.
"I'm… going to call my mother…" Tsuna said. Reborn nodded stiffly.
"You do that."
-o-
"My little Tuna-fish is a parent now!"
If Tsuna had known that Iemitsu was home, he would never have called.
"Who's the lucky girl?"
"Dad, it's not like that," Tsuna tried to say. Unfortunately, he spoke at the same time Reborn entered the room.
"Tsunayoshi," Reborn began and then he saw Iemitsu's hologram. There was total, utter, silence for a while before Iemitsu started to shout.
"HOW DARE YOU—"
"DAD!"
"—MY PRECIOUS SON! YOU HAVE COERCED HIM! THERE IS NO WAY HE WOULD CHOOSE SOMEONE LIKE—"
"DAD OH MY GOD."
Kyoya, finally, started to cry.

Reborn asked for custody of Fon's child for a reason. I might cover it in later chapters.
