I'm being piled up with college work. Still trying to make time for writing. For anyone interested, I've released a Naruto story with a somewhat similar element as the one used in this story. Forgive the short chapter, but I couldn't let you wait any longer. Next update may take a while.

Chapter 10 – The One True Sky
Act One

"So you're Rokudo Mukuro?"

"Why yes I am, are you Vongola Decimo?" Mukuro asked with a teasing smile. Mukuro was happy to see the person that would make his life better. Taking over Sawada Tezuka's body would make him and his friends rich. They wouldn't have to hide from the Vindice anymore either, and the most pleasant part of it all would be that he could destroy the Vongola from within.

"Zuka, this isn't and opponent to underestimate got that?" The child infant spoke with a sharp gaze. Next to who could only be Reborn, one of the I Prescelti Sette, Hayato Gokudera stood. Mukuro wasn't really worried about the bombardier. What did catch him off-guard was the glowing ball on top of Reborn's hat. He was going to pay close attention to it.

"Alright Reborn-sensei," Decimo said with a tone that Mukuro recognized very easily. It was the one that he used when lying to someone.

"Well," Mukuro said as he stood from his throne like seat, "shall we begin?" He gave another teasing smile. Decimo's hands were burning red with flames, "dying will flames?"

"That won't save you Decimo," Mukuro laughed as he flicked his fingers and disappeared into a purple mist seconds later.

{One True Sky}

Tsuna didn't know why he did it. It felt horrible, but also good. He looked over his shoulder behind him to see Takeshi limping forward.

"Try to keep up Takeshi-san," Tsuna said silently. He fed Takeshi some of his own dying will flames. To his surprise something shocking happened.

"I'll heal you Takeshi-san," Tsuna said as he put his hand on Takeshi's forehead. His entire hand shook when he made contact with Takeshi's forehead. A blinding light engulfed both of them. Tsuna could have sworn that he saw his own flames being converted into blue flames that were sucked into Takeshi-san's mouth and eyes.

Tsuna planned for his own flames to heal Takeshi's wounds and thus replenishing Takeshi's flame supply. Instead his own flames were converted to Takeshi's dying will flame type.

"Alright Tsuna," Takeshi said happily. That bothered Tsuna a lot. How could such a person behave in that way? For all he knew, Tsuna was about to kill him.

"Hey Tsuna," he heard Takeshi say behind him as they turned around the back of the broken Kokuyo school, "thank you."

Tsuna stopped dead in his track. Above him the sky was roaring with lightning. Small pebbles of rain fell down on the two. "What?"

"I said thank you."

"But why? I'm your enemy," the smell of rain entered Tsuna's nose. The wind made the green trees across Kokuyo middle school move.

"Because you saved my life," Takeshi's eyes looked honest.

"I could still kill you, you know," Tsuna said with narrowed eyes. He didn't know where Takeshi was going with this. As far as he was considered, Takeshi was his prisoner. A prisoner he wouldn't have if he hadn't saved him.

"But you won't," Takeshi said and suddenly years of hitman-like training appeared on Takeshi's face. Tsuna widened his eyes. It wasn't that he was scared of Takeshi, but impressed by the honesty and assurance in his facial expression.

Tsuna nodded dumbfounded, "why are you friends with Tezuka?" He needed to know that.

"Huh?" Takeshi looked confused, "because he's a friend that I would protect with my life! He saved my life once!"

Tsuna felt horrible for knowing that his brother was both the cause and savior of Takeshi's troubles. "He's not what you think he is," Tsuna said while he looked down.

A hand suddenly clasped his shoulder. Tsuna looked up and saw Takeshi smiling, "you don't know him like I do, but you know what? We can all be friends after this!"

Tsuna shook the arm away. "We'll see," he whispered. He turned and continued running towards the school. Takeshi was right behind him.

Ten minutes later Tsuna and Takeshi were inside the school. Both of them stopped in front of a door where a lot of noise was coming from. Tsuna was about to open the door when he heard an ear deafening scream coming from behind it. Takeshi looked alarmed, "that's Tezuka!" Takeshi kicked the door open with brute force.

"Wait," Tsuna started distressed, "don't just g-," but Tsuna was already too late. Takeshi had already entered the large room. The feeling from before, the feeling that wouldn't let him go, it returned. But this time it came from multiple places. When he looked carefully into the purple mist inside the room, he could see a storm and sky flame dying out slowly.

"Is that it Vongola Decimo? I really thought Vongola's future boss would be much stronger," a voice with mischief said from out of nowhere.

Tsuna immediately recognized the flame type that was being used; mist. "Where are you Fran? I could use your help right about now," he hoped that he would find Fran in the school's corridors, but his best friend was nowhere to be seen. That and the pain in his head that was about to crush him made him want to throw up, "no, I need to think clearly."

"Kufufu, two more visitors? How nice, I think I'll need to welcome you two with sweets," the voice with mischief said.

Tsuna's years of mafia training kicked in and he became very cautious.

"Tezuka, where are you? Are you-, agh!" Takeshi's grunt was loud at first, but then slowly faded.

"Kufufu, that's one down, one to go."

"I need to get rid of this mist before he attacks, or else I'm done for," Tsuna immediately began looking around. The purple mist was everywhere, behind him, in front of him, above him. He prayed that Reborn wasn't around, because what he was about to do was risky, "Fiamma." Tsuna raised both his hands upwards, palms towards his face, and began concentrating. The mischievous voice was nearby, so he had to hurry up. Flames gathered around his hands.

"Kufufu, what are you doing? Think you can beat me?"

Tsuna smiled, "we'll see," and pulled his hands back until his chest muscles stretched, and then propelled his hands forward. The flames soared around the purple mist. Slowly the mist was being engulfed by the flames. The flames were overpowering the mist and disappearing along with the mist as it spread around.

When the flames and mist died out, Tsuna looked at the floor of the room. Gokudera and Tezuka were out along with Takeshi. They were lying around the corners of the room. None of them were in live-or-death condition, but if he didn't act soon, they would enter a critical state.

"Who are you?" The mischievous voice asked in wonder. Purple mist appeared out of nowhere in front of him. The mist condensed into a human silhouette before taking the appearance of a handsome young man with dark hair, pale skin and green and dark clothing.

Tsuna didn't like the bad vibe that he was getting from the stranger that could only be one person.

"You're Rokudo Mukuro," Tsuna said with narrowed eyes
