A Contract to Destroy the Mafia.

Summary: With Chrome physically broken in the hospital and Tsunayoshi mentally broken with Mafia life, what better opportunity is there for Mukuro to make good on his threat and finally possess Tsunayoshi's body? So who will win? Will Mukuro destroy the Mafia and take over the world or will the Guardians be able to figure everything out and save Tsunayoshi before it's too late?

Heya guys.

This is an idea I've had forever and finally decided to write down.

So I hope you all enjoy it!

A warning for readers of How a Thief Changed the Mafia: I would be careful when reading this and would most likely not since this is an arc I have planned for Thief. I'm sure some of you have noticed the hints I've dropped, especially when Tsuna was having that rough patch a few chapters ago. However I wanted to write this down before someone else stole my idea- which I've already had happen a few times. Of course, with the addition of Shinichi and Kaito and the Vindice things will end up a little differently, but the start and middle will be similar. So read at your own risk.

Chapter 1:

Make a Contract with Me

Tsunayoshi Sawada had been locked in his room for the past few days, refusing to see anyone and refusing to even eat. For it was all his fault that Chrome was laying in the Vongola infirmary in critical condition. Tsunayoshi had finally cracked mentally. The innocent boy had finally seen enough of the dark side of the Mafia and could no longer take it. He'd been forced to interrogate prisoners for information, he'd been forced to punish Mafioso for their crimes. And today he had been pushed one step too far. Vongola Nono had demanded that Tsunayoshi kill the traitor that had betrayed the Vongola and caused Chrome's injuries.

So the boy had gone, and started the mission, his anger fuelling his body and his fists into action. On and on it went, until Tsunayoshi eventually had to deal the final, killing blow. And just like everyone knew, he couldn't do it. The thought of becoming a killer, of ending someone's life had been too much for the boy to handle so he had run. He had run from the room, burst into the sky and finally locked himself in his room.

And it was into this room that Mukuro materialised.

He walks over to the bed where Tsunayoshi is sleeping in a fitful state, no doubt plagued with nightmares. But the sudden burst of Mist flames wakes his from his dream, as attuned to his Guardians as he was. Mukuro sits on the side, his face looking over Tsunayoshi.

The first thing Tsunayoshi sees when he wakes up is Mukuro's face, his eyes gleaming and a fake looking pout of his face. But as worn out, both mentally and emotionally as he is, Tsunayoshi only sees the sympathetic, heartbroken façade Mukuro had put on- falsely acting as if mourning over Chrome's injuries.

"Mukuro?" Tsunayoshi mumbles out. Tears form in his eyes and spill down his cheeks. "I'm so sorry Mukuro. If it wasn't for me, Chrome wouldn't be in that state. And I couldn't even get revenge for you. I'm so pathetic. I'm sorry Mukuro"

Mukuro brings a hand over and runs it down Tsunayoshi's face, wiping the tears away. 'I can't believe that I can touch you with this hand. You are so naïve Tsunayoshi, that it's going to be so easy to capture you. You don't even suspect a thing'

"I know that you are to blame Tsunayoshi" Mukuro admits, and Tsunayoshi's face falls. He stares up at Mukuro and finds his eyes drawn to the one red eye his illusionist has and is frightened of the gleam he finds there. He's sure that Mukuro is going to take revenge on him for getting Chrome harmed. He couldn't be more wrong.

Mukuro sees Tsunayoshi's expression and can guess where he is looking. Internally, he smirks 'You look at my odd eye whilst projecting a frightened face. Your mind couldn't be farther from the truth Tsunayoshi. You, who are so naïve, so innocent, so god-damned pure, wouldn't even consider what I am about to do. I am so happy to have met you Tsunayoshi. You couldn't be more perfect for fulfilling out my plans. Your personality, your position in the Mafia world, your connections and the people around you. It's all so perfect that it's almost cliché.'

"I know that, yet it's not entirely your fault" finishes Mukuro, brushing his hand over Tsunayoshi's cheek. Perking up, Tsunayoshi's eyes shine with hope. "You have done so much for me and Chrome. So let me help you in return"

Tsunayoshi had had enough of the Mafia, and was more than keen to take any hand that was willing to pull him out of the darkness. He didn't belong there, he couldn't survive there for much longer. He needed out, and he needed it now. So nodding furiously, Tsunayoshi forgets how dangerous his illusionist is, and accepts the help line the illusionist is offering.

Placing his hands on either side of Tsunayoshi's temples, he whispers "Close your eyes". Tsunayoshi does so, and Mukuro lowers his head so their foreheads are resting together. In a burst of Mist flames, the dance beings.

When Tsunayoshi closes his eyes, he finds himself in some sort of empty space filled with purple mist. Thunder rumbles in the distance and Tsunayoshi jumps with a squeak, but is quickly caught in strong arms.

"You don't deserve what's happened to you Tsunayoshi." Says Mukuro, the owner of those strong arms keeping him upright. "The Arcobaleno had no right to walk into your life and rearrange it as he wishes. He must be blind to not be able to see that this kind of life doesn't suit you." Suddenly, the world goes black and Mukuro is no longer holding him. His voice sounds from somewhere far in the distance. "Does he think you liked doing this?"

Tsunayoshi hears a scream behind him and he slowly turns around to look at it. There he sees himself holding a bloody knife whilst a man tied to a chair begs for forgiveness. He watches as the other him stabs the knife into the man's hand. Tsunayoshi has to turn away from the image. His colder Dying Will self might be able to handle it, but he certainly could not. So he runs in the opposite direction from the image, not having a clue where he is going since all he can see is black.

Yet as he keeps on running, more images of his recent Mafia activity appear before him. It makes him want to be sick. He wants to deny that the man he is watching is indeed himself. He wants to run away and hide from it all. But all he can keep doing is run towards the voice that is offering comfort.

"Enough, make it stop, please" he begs, collapsing to his knees and crying his eyes out once more.

"Oya? This is not the Decimo I know" says Mukuro, still not in sight.

"It's not like I ever wanted to be Decimo!" Tsunayoshi shouts back in return. "I never wanted any of this to happen. In fact, I just wish I could turn back time and make sure it never happened. I wish I could forget about it all and live a normal life. Anything would be better than this"

Mukuro smiles. He reappears infront of the broken boy, sure in the fact that he is leading this dance, and that control is not going to change hands anytime soon.

He kneels before the boy and grabs his chin, forcing Tsunayoshi to look into his eyes. "I can make that happen for you."

Mukuro wants to laugh out loud at the pathetic face Tsunayoshi makes. He looks like a puppy, hope shining in his eyes. Hope, trust and not a hint of suspicion.

"Please" Tsunayoshi whispers. He had had enough.

"I can make it so that you will never feel like this again. I can provide everything you have ever wanted. Friends, a loving family. And I can promise that there will be no fighting, no blood shed ever again. You won't ever have to worry that your friends are in danger, you will never have to fight to protect them since there is nothing they need protecting from. Never again shall you repeat the actions in those memories."

"Please Mukuro." Begs Tsunayoshi.

"I will make you forget everything about the Mafia. You will never have to relive the memories. Does that sound good to you?" Mukuro offers, still staring deeply into the warm brown eyes. Or what used to be warm, before the Mafia came along and broke them, turning them cold and lifeless.

"It does. I don't ever want to remember" replies Tsunayoshi, looking upwards at his saviour.

"So, will you make a contract with me? Do so and I'll erase everything you fear. This is the last act you need to make in your role as Decimo. So come on, make a contract with me, before you lose your memory."

Tsunayoshi's eyes widen. "B-but Mukuro"

However Mukuro cuts him off and the world around them changes once more. They are outside in Japan. The sun is shining, the birds are singing and nothing could seem more peaceful. There is music all around them, the sounds of a festival. But it's not Japanese music, no, it sounds more foreign.

Tsunayoshi looks to the right and sees all of his friends, sat on a picnic blanket enjoying the festival. No one is shouting, no weapons are in sight. Just everyone getting along. Gokudera sees him and runs over, offering a hand to Tsunayoshi, who is still sat on the floor.

"Come on Tsuna, you're missing the carnival!" he says, smiling at him. The others all notice and shout at him to come on and join in the fun too. And how Tsunayoshi wishes that he could run over there and enjoy the party with them.

The music gets louder and louder until the carnival procession is in sight. His friends all stand up and start dancing to the music, the children shouting and laughing. "Come on Tsuna, come over and dance with us" shouts Yamamoto. Haru and Kyoko stop their own dancing to reach a hand each towards him. "Come on Tsu-kun" they shout.

"Kufufufu~. This is the world I can offer you Tsunayoshi. This is the world you could be living in. So why not take the opportunity? Let us dance in the Mist's Carnival. In this pure and beautiful world you'll never have to worry about anything ever again."

Mukuro watches as Tsunayoshi's face lights up and smiles. It's clear to him that this is what Tsunayoshi wishes for, what he desires. Well of course it would be. It's created out of his subconscious after all. His Mist Flames had delved right into Tsunayoshi's heart through the crack the Mafia had created there. Having his Mist Flames wrapped around Tsunayoshi's heart made it so easy to manipulate the boy. He smirks at how simple this has been. 'The manipulated you is in an eternal samba with me. I'll lead you along on this fast dance until you have no choice but to follow my lead. I'll pull you and spin you until you have no clue which way is up. You have never been in control of your own life Tsunayoshi. First it was the Arcobaleno pulling the strings, and now it's me. '

Now to seal the deal. Mukuro knew he was being mean with what he did next. But the more broken Tsunayoshi was the better and easier it would be. He was so close. So close to possessing that body.

With a click of his fingers, the world around them changes once more and now they are surrounded once again by images of Tsunayoshi's mafia dealings. The screams, the grunts, the pleas for forgiveness resound and echo all around them.

But Tsunayoshi can't take that anymore. He looks away from the images. Whimpering in fright, he just wants everything to be over. He wants away from this, from this world.

Mukuro leans in close to the boy and whispers "I will comfort you if you wish for it. There is no need for you to suffer all alone. You haven't done anything to deserve this." He wraps his arms around the trembling boy. "Is it okay for a moment?" he asks.

He is more than pleased when Tsunayoshi whimpers once more and buries his head into Mukuro's chest. He is even more pleased when he can feel the physical body on the outside cling onto him as well, a true show of how deep his desire for comfort was.

"Oya oya, or maybe you'd want comfort for eternity?" Mukuro admits he was shocked at this reaction, but it was a pleasant shock. It showed that he was almost there, almost ready to take the final step. He feels Tsunayoshi nod against his chest, silently asking for eternal comfort without words. Mukuro leans back slightly to get a good look at Tsunayoshi's face. He puts on a fake look of confusion. "Oya? I don't understand why you cry Tsunayoshi. It seems like it's my fault."

Tsunayoshi shakes his head. "No Mukuro it's not. It's just really clear to me now just how much I hate the Mafia, that's all. I feel really bad for dragging all of the others into it. I'm such a horrible person"

"Kufufufu~, but that's not true Tsunayoshi. It is they who have dragged you into this. Wasn't it the Arcobaleno who walked in, dragged you by the collar and said "Come on and recognise it, Your destiny"? Isn't it he who forced you into the position of Decimo and placed the weight of saving the Mafia on your shoulders? Tsunayoshi, it is not your fault. They have placed you in a position where once you misstep, it starts breaking. They have forced you into a position where you cannot make a mistake. However they do not have the right to force that kind of pressure onto you"

Tsunayoshi looks down and contemplates this. A lot of what Mukuro had said was true. Tsunayoshi can't believe what a fool he's been.

Mukuro smiles once more. Everything was going just to plan. 'The sad-eyed you is my lovely doll. You are all mine to play with, to do as I please. I'm going to be the one pulling your strings and now, there is nothing you can do about it.'

"I agree" mumbles Tsunayoshi, most likely not even realising he's spoken out loud.

'That's right'

Out in the real world, Mukuro materialises the top part of his trident and holds it in his hand, ready and waiting for the final strike.

"So then, will you make a contract with me, before you lose all of your memories?" Asks Mukuro one more time.

Tsunayoshi looks up. Tsunayoshi nods. Tsunayoshi begs. "Please".

Out in the real world, Mukuro makes his final move, scratching Tsunayoshi's pale skin with the tip of his trident. Dropping it, he reaches into his jacket pocket and draws out a gun holding the Estraneo's forbidden bullet. Shooting himself with it, he smirks.

Now his plan can start.

I know lots of people think Kufufu no fu~ Boku to Keiyaku is about Chrome. And whilst I can see it as a possible love confession, when I first read the lyrics of this song, this is what came into my mind. So here it is. Plus taking over the world makes for a more interesting story.

Hope to see you all next time
