Tsuna and Vongola Nono kept in contact. In the years of growing up Tsuna managed to get a name for himself in the mafia known as Neo Primo. One day the two made a bet to fool the world greatest hitman the sun Arcobaleno. They named it 'Project Pacifier'.

"Granpa! Can I call you sometime?" Says a innocent four year old Tsunayoshi Sawada who grabbed the shirt of the old man who smiled at him. "Sure you can." He says with a smile on his face. He looked back to his parents who where hugging each other.

"Here is my phone number." He says with a smile as he gave Tsunayoshi a small paper. Suddenly a small orange flame lit and was put on his forehead. "I've put everything back like it was. But promise me you'll keep training Ike?" He says as he watches the four year old nod. "Good boy. Now I have to go okay? Iemitsu it's time to go!" Says the old man to Tsuna's father who looked sad.

"Tsuna Nana I have to go. I will come as soon as possible okay?" Says Iemitsu with a goofy smile on his face.

Nana wiped a view tears away. "See you soon dear" She says with a sad smile. "Bye dad.. Bye Grandpa." Says Tsuna as he glared at his father. The old man dragged Iemitsu away from his family not knowing what the future will bring.

8 years later.

"You sure Grandpa? Did you know that the Arcobaleno is been set up new again?" Says a 12 year old Tsuna. "Where did you get that information from." Says de voice of a old man on the other side of the phone.

Tsuna snickers at that. "I got my ways to get my hands on it." 'Bermuda talks too much.' Says 12 year old teen.

"Tsu-kun I'm home!" Sounds the voice of Nana. "Mom's home a moment please." Says Tsuna as he put the phone on his desk. "Mom what do we have for dinner?" Asks Tsuna "Beef stew with sweet potato, why?" "Just curious." Says Tsuna with a grin.

"Let me guess grandpa is on the phone, Am I right?" Says Nana as she narrowed her eyes watching her son who nodded. "Then give him a message to Iemitsu that if he won't come home anytime soon I will give him no home cooking again." Says Nana as a vain popped on her head. "With pleasure Mom." Answers Tsuna with a happy grin and went back to his room and put his phone only to hear shouting on the other side.

"VOOOOOOOOOIIIIIII! Old man are you sure you want me to assassinate the CEDEF head?" Sounds the voice that Tsuna knows too well. "Ow my ears! Squalo keep your voice down a bit." Says Tsuna.

"What did your mother say Tsuna." Asked the old man. "She wants you to deliver a message to the idiot. If he doesn't come home anytime soon mom will refuse to cook meals for him." Then laughter sounded.

"Well I make sure the message is delivered to him." Says the old man. "Ninth Reborn has just returned but there is a Small problem..." Says the voice known as the storm guardian of the man. "What is that problem." Asks the Ninth.

"The last hair has been found dead..." Says the man. The ninth dropped the phone he still held that was stil connected to Tsuna who also heard the news knowing what it means for him. Squalo picked the phone for the shocked boss who just lost his last son.

"I want you guys to leave me alone for now.. Squalo can you give me my phone back." Says the Ninth as he held out his hand.

The loud swordsman gave him the phone back as he followed the rest to leave the Don alone for now.

When the ninth was sure nobody was there he began to speak. "Tsuna you know what it means now you know you're the only left." He says. "I know and you know that I don't need training at all but from experience I know they will complain that I'm just a kid. Maybe we can have some fun with some of the hitman by fooling them that I'm no good at all and bad at everything." Says Tsuna with a snicker.

The idea made the Ninth a devilish smile on his lips. "Tsuna are you in for fooling Reborn himself." He suggested making clear that he's challenging Tsuna in fooling the world greatest Hitman. "I still get complaining from Dino how he's torturous while training him." Says Tsuna. "Nobody has managed to fool him in his whole history. Are you still in for it?" The ninth asked knowingly.

"Neh grandpa what will I get if I manage to fool him?" Asked Tsuna curious. "I bet the whole Vongola on it. And if you fail you come live here in Italy work as my personal assistant for a year." Says the ninth playfully but also knowing the said hitman won't be happy at all if he finds out. "Deal. When will I expect him?" Says Tsuna.

"About one to two weeks so you have to prepare your self. I wish you good luck Tsuna." Says the ninth. "Okay there goes my peace , at least I get some fun with Reborn. Does Dad know about my work with the mafia?" Says Tsuna "No he doesn't know at all, but he knows your name in the Mafia Neo Primo." Says the old man. "Then you know I have to inform my man about our bet grandpa." Tsuna said with a smile on his lips. "Then I end our call Tsuna I let you know when he's on his way." Says the ninth.

"I'll keep contact with you grandpa just to let you know how this bet is going. Oh can you let mukuro on the loose in about three months? To ad a bit more fun then the varia. Xan-nii would also join the fun and ad a ring battle to it." Says Tsuna the old man got to know the idea of what Tsuna's plans are with the sun arcobaleno.

"Let's call this project pacifier X." Says the ninth laughing at this.

The two ended the call as Tsuna's mother called that dinner is ready.

The ninth dialed a number on a other phone. "Reborn I have a job for you come as soon as possible." He said in a serious voice.
