Rated M for blood and gore.

I don't own Katekyo Hitman Reborn or any other character from it. If I did, things would get really nasty, and our dear romance lovers wouldn't like that now would they?

Just decided to try my first Reborn fic with my favorite type of story. I'm a sick person...

I'll post the next chapter within this week. Sorry for any grammar mistake I might have done. Anyway, on with the story!

Prologue Chapter - Nightmare

Tsuna could feel the chains, cold and hard on his wrists. This again, every day now... He had no hope anymore...

Tsuna tried to adjust his position on the floor, maybe feel less uncomfortable, but he couldn't move. Had no energy for this at all. The chains pulled his arms above his head, in the dark, dirty room. He could hear water drops falling erratically, the silent itself reminded him of metal. There's no way out.

He looked at him again. Just expected. He wasn't there a second ago. The first time, he thought it was a mirror in front of him. But it was indeed him in his familiar hyper mode, standing in front of Tsuna with his arms crossed and smiling. Not his normal, warm smile, but a really dark smile that reminded him about whom he was here, every night.

"W-why every time...?" Tsuna asked himself on the verge of tears. Forcing the tears back. This has been happening randomly every week, but recently changed to absolutely every night. He couldn't take it anymore. Sleepless nights were part of his routine, just when he miraculously managed to escape the terror of finding himself here. Always thinking, waiting for this nightmare to happen.

"Let's play a different game today." His counterpart said, almost enthusiastic with the idea. His ominous smile lightened by the only small light on the wall. He took a step away, showing a girl he knew very well behind him and making a gesture with his arm, as if he was presenting her to Tsuna.

Tsuna gasped. "What are you planning to do with her? ! Kyoko-chan has nothing to do with this!" Seeing her in that position, unconscious, barely clothed and chained just like him made him want to cry and scream. But he held it in. He held it in because crying had been fatal in the last nightmare, he would murder her horribly in front of him if he did so! He wouldn't be able to handle seeing her blood, her screams of pain.

"Of course she has! She's our friend, isn't she? We love her, don't we? So she has everything to do with this, my little pathetic self."

"She didn't do anything! Please!"

"So what?"

"This can't be!" Tsuna's eyes were wide and terrified. He wanted to wake up! Just this once, somebody, even if someone needed to hit him in the face with a bat or even stab him, somebody needed to wake him up! Tsuna desperately keep repeating 'wake up, wake up, wake up!' like a chant, hopelessly wishing that even Reborn would hear his mental pleads and wake him up!

"You won't wake up unless I say so." His other self mentioned casually, calmly walking towards the corner of the room, looking for something.

Tsuna knew what he had in that corner. So many sharp objects he had displayed there. "W-what are you doing...?" Tsuna asked, afraid of imagining what new 'game' he had in mind.

"Ah, this one." He proudly showed Tsuna an assassination knife, one of the worst he had used to cause pain on his body, and walked towards Kyoko.

"No, wait!" Tsuna yelled, hopelessly wishing he would just stop! He had seen his own hands torture and kill horribly everyone he though as a friend. For months, its realism tortured Tsuna mentally even thought he had already tortured Tsuna physically once a week, long before he started murdering his friends in front of him. On the same day he though 'At least my friends are fine...'

On that same night, he did the same thing he was doing to Tsuna on the previous week. Pure torture, it pained him to look, so much he couldn't stop looking. His mind couldn't register nothing but the pain, it wouldn't do anything but that!

He unchained Kyoko.

"Please don't..." Tsuna pleaded, begging not to hurt her.

He dragged her by the hair and tossed her carelessly in front of him.

Tsuna bit his lip. That rough floor probably hurt her skin. But he couldn't cry for what was about to happen, he just couldn't. Staring at her in front of him was already torture, he wanted it to be over, but it just wouldn't! He would have to suffer from this forever! It was all Reborn's fault for appearing with all that mafia shit! For risking his life! For dragging his friend into this!

Maybe not having friends at all was better than seeing them like this...

It was all his fault, everything!

Tsuna felt tears roll down on his face. He knew what was coming.

"Ooh, I see tears?" His counterpart said, faking sympathy. Tsuna knew, he was going to rip her throat now, he knew he couldn't cry, but couldn't hold it anymore- His thoughts was interrupted by a sharp pain on his chest and he screamed in agony. "You thought I was going to stab her?" Tsuna could feel him move the knife inside him, as if painfully ripping his heart. It was a nightmare after all, he couldn't die, unfortunately... "Don't be stupid, she's a woman..." His counterpart said amusingly.

With a big smile, he grabbed her hair and pulled her head until Tsuna could see her face clearly, struggling to keep his eyes open with the pain, just to take a look at her face.

"And here goes a question that you, as a man, should know. What do we do with women?"

Tsuna gasped. No... Not that, not... not in front of him... of all people...

"Oh yes, even you know..." He said, his expression showing so much madness that Tsuna couldn't find words. "Even you know, we fuck them!"

Tsuna' eyes widened. He felt hate consume his thoughts. The feeling was so alien to him, yet, it came so easily now, so naturally he felt disgusting... So at ease, letting your rage out gave so much relief to his stressed mind...

His counterpart didn't react much. He kneeled at Kyoko's side and stroked her skin, smiling and looking almost proud as he watched Tsuna curse him mindlessly in his head and struggle to free himself and kill his other self. He was his counterpart after all, he could feel it. "You progressed a lot this month..." He whispered and tilted his head a little. His expression completely peaceful when he laid a hand on Tsuna's cheek, making him even more uncontrollable. "Don't worry. Once this dominates your mind, all the pain will be gone~"
