I don't own Hitman Reborn!

Summary: Slight AU. The Estraneo Famiglia was destroyed by the Vendicare. And they abandoned their projects and everything. Here comes our scientist Verde! He found an assassin project named Tsunayoshi. What will the Arcobaleno do? Ver27; implied R27; G27; X27

Music When Writing: Let the Bodies Hit the Floor – Drowning Pools

Warning: All the previous warnings.

Without further ado let's start~!

~Beyond Verde's Scientific Knowledge~

Twentieth Theorem: Arcobaleno. Loss.

The walk to the mountain top wasn't really on his mind right now. He kept on walking, and only looked at Luche's overlarge hat to know where to go. He'd left Tsunayoshi's corpse (he told them he was in a coma) with the only person in Vongola he didn't really dislike, Xanxus.

But that also meant putting him under the wings of his second most hated person after Giotto Vongola, Belphegor Prince the Ripper and his junior Fran. Still, Verde trusted Xanxus to take better care of Tsuna this time. Since the last time, Xanxus didn't really see Tsunayoshi, Verde made sure he didn't make the same mistake.

He noticed Colonnello, Lal Mirch's apprentice, tailing them, but he didn't bother to care. There was something else more important than someone else willing to be Arcobaleno in Lal's place. And it was Tsunayoshi.

Luche told him that the moment he got a pacifier (he was confused of this) he should make a wish, and that wish will definitely be granted. It took long, but Luche finally convinced him. And here he was, complying with such an unscientific babble.

All for Tsunayoshi's sake.

As they reached the top, Verde took his designated position and looked at the Sky. Every one of them that stood in the Sky-Earth battle some time ago would remember this presence. The all carefree and intimidating. It was Ouranos.

You are the chosen ones. I shall give you one wish in exchange of this holy pacifier.

Verde closed his eyes and gritted his teeth. He suddenly saw flashes of scenes. Tsunayoshi— destroying all their pacifiers. It was something that was supposed to happen, but didn't happen anyways.

Bring back Tsunayoshi! Bring him back to life!

There was a thunderous sound in Verde's ears, but no Lightning to be seen.

Very well. Your wish will be granted.

The light went brighter, and he used his hands to cover his glasses.

But, when he opened his eyes, he was no longer Verde Keyman.

Bring back Tsunayoshi! Bring him back to life!

Tsuna woke up with a jolt. Verde-sama's voice was there, shouting, pleading, and desperate. What happened? Was he… was he dead?

"Oh, you woke up." Xanxus was there sitting on his armchair beside Tsuna's bed. There were three bottles of Tequila on his bedside table. "You're asleep for three days, pathetic scum." Tsuna laughed nervously to his brother's gruff way of speaking. "Nii-chan…" He spoke, at first, he thought Xanxus will kill him for calling him that, but the Varia boss didn't say anything.

"Where am I? How am I here?" He asked. He wasn't in Verde-sama's laboratory. He didn't know where he was. "This is Varia HQ. You know this place." Xanxus answered briefly before opening the fourth bottle of tequila. "And that shit Verde was the one who brought you here three days ago." Tsuna flinched. He immediately looked to the calendar to know that today was two months after the parent-teacher meeting.

That's not true. He'd been asleep; he'd been dead for two months.

Tsuna closed his eyes. He wanted to remember about the parent-teacher meeting, but he was shown scenes directly within his head.

It was Verde-sama, he wished that he was alive again before disappearing into a bright light. Tsuna gasped and opened his eyes. "Brat?" Xanxus asked. Tsuna's entire body shook as he sobbed. Tears streaming down his face as he concluded what happened.

Verde-sama… sacrificed something big to bring him back to life.

Two months after finding himself in the care of Varia, Reborn came in a form Tsuna never expected.

He was a baby. A one year old baby with the head, personality, and mind of his older self. Tsuna wanted to ask Reborn about it. About the others, about Verde-sama. But, Reborn only kicked him on the back of his head and refused.

Reborn became Tsuna's so-called home-tutor, teaching him to be a Vongola boss who'll succeed Giotto. Tsuna remembered everything about Giotto and Xanxus, he was happy. He was happy. But… he was also empty.

He'd lost everything.

He'd lost his everything.

He'd lost his Verde-sama.

Short chapter yes yes I know. I just didn't want to fit these words to the previous chapter. But hey! At least you didn't need to wait for the next chapter! Please review this too? :3
