Summary: Reborn shot Tsuna with a new bullet Giannini made, which make his Hyper Dying Will self split from him. Even Giannini himself doesn't know when will the bullet wear out and the two Tsunas will be one again. The two Vongola Decimos have to live together in one house, go to school together, train together, share one bed together… before they merge together.

Warning: None.

~Prologue~

"W-what are you doing with that gun Reborn?"

The suit-dressed infant smirked at his student's silent panic face. The brunette stepped one step back, ready to run at any moment. He was on his way home from school when Reborn suddenly jumped out from nowhere and point his little green gun at the young Decimo. Gokudera excused himself to go home fist for UMA searching. Yamamoto got baseball practice. That leaves Tsuna went home alone and vulrable to any attack…

…Such as the one pointing a goddamn gun at his face right in front of him.

"Don't worry Tsuna, it's Giannini's latest invention: A bullet that extract your HDW self from your body. He only made two of this bullet and one is currently being tested on Basil. You are obligated to test this bullet… Or else..."

"WAIT! WAIT! Why should it be me!?" Tsuna shrieked in panic

"Because aside from Basil only YOU use HDW Mode."

BANG!

The bullet flew to Tsuna in slow motion. Like a normal Dying Will bullet, it splited in half, a light came out and hit the brunette right in the middle of his forehead. And like dejavu, the young Decimo feel backward, life flashed before his eye… But his conscious is fading instead of coming back to life like every other times in the past.

Before completely unconscious, Tsuna felt himself fell onto something soft and very warm.

Okay… now he's back to life.

"Ugh… Reborn…"

He can feel something moving behind his back. A person to be exact. That person sat up and Tsuna slid down his or her belly. The brunette opened his eyes slowly…

…only to see someone look exactly like him looked down on him, amber eyes looked at chocolate eyes.

"HIIIIIIIIIIEEEEEEEEEEEEEEEEE EEEEEEEEEEE~!"

Tsuna scrambled away from his look-alike quickly in panic after let out a REALLY LOUD shriek and crashed his back against a wall. The two brunettes looked at each other shocked. They both noted their surrounding, still on the street from their way home.

"You both were out for exact 40 seconds after being shot. That was kinda slow."

Two Tsunas looked at Reborn who was looking at his green watch (which was Leon turned into). "Reborn! Who the hell is this and why does he look exactly like me!?" The brown-eyed brunette shouted.

"Dame-Tsuna, he's your HDW self, didn't I tell you before?"

Both Tsunas remembered. Their tutor did said something about a splitting bullet that extract Hyper Dying Will…

"So…how long will this bullet last?" Hyper-Tsuna asked.

Reborn's smirk disappeared making both Tsunas flinched. The green chameleon turned into a cellphone and the Sun Arcobaleno used it to call someone. "Hello! How long did you say the bullet would last? ….. I see." He shut his Leon phone then looked at his now two students.

"No idea." Said Reborn.

"HIIIE! WHAT!?" Tsuna shrieked again but this time his mouth was covered by his HDW self. The brunette noted that his other self's hand felt exactly like his hand covering his own mouth. It felt weird, but also nice and kind of… safe.

"But Reborn, what if it takes more than a day to wear out? What if it takes even weeks or month? And has Basil turned back to his one self yet?" The amber-eyed asked.

"Then you will have to live with it!" Tsuna almost let out another shriek if his Hyper self didn't cover his mouth. "You will live together, share your bed, your stuffs, go to school together and train together too. There's no other choice left."

"But what will we explain to mom about having another me in the house? Scratch that! What will mom react when she sees two Tsunas existing?"

"Make up a reason yourself." Reborn turned his back to the two brunettes, Leon turned into a mini-car and he jumped on it. "I'll be waiting at home, Dame-Tsuna and Haipa-Tsuna (Hyper Tsuna)!"

And with that, the baby hitmen drove away, leaving Tsuna with his HDW self still covering his mouth to prevent him from screaming in panic. The two stared at their tutor until he's fully gone, then Hyper Tsuna carefully removed his hand from his original self. Lucky for him Tsuna was in too much shock to scream murder loud like he always did. "Tsuna, let's go home… While we walk we can both think of something to tell mom about… well… me."

The brown-eyed boy turned to his HDW self. "Y-yeah… Good idea…" HDW Tsuna smiled reassuringly then pick Tsuna's bag up and they both go home.
