Prologue

"Another case of civil kidnapping? That's odd; true mafiosi should know not to attract stares."

A man approached him, his steps sure and a light in his eyes which made him quiver under the hard stare.

"Eh? What do you want, sir?"

The words were uttered softly, yet the other persons in the room still heard them. One of them, a dark haired young adult regarded the former from under his tilted fedora. It was true, Mafioso were not supposed to be known to the Light world, up there. But there were leaks, as always in each and every society, hidden or not, though less than during the reign of the Quattro.

"Juudaime, do you want me to send men to reopen the 'Call Journal' affair?"

"Please do," the now-dubbed Juudaime gave his consent immediately, his Intuition flaring up. His silver haired right hand man retreated silently to call his subordinates.

His Intuition was sending warning bells colliding within his head and into his skull, almost rattling his cranium. It was like when Xanxus or Byakuran came to try to take his Family away and no one touched the Neo-Primo's family. No one who wanted to live.

He shuffled in mountains of paperwork, placing a pile here and moving another one there. He gave a small 'Aha!' of triumph when he came out of the sea of paper while clutching about half a dozen folders.

The kidnapping cases spread over around six years, which meant they started four years before the Inheritance Ritual.

The stranger cocked his head to the side in a silent demand. His body stiffened. That man was not as innocent as he looked, he could feel it.

Air felt heavy around him. He could feel a strength exceeding humans' judgement. Danger, it screeched.

Now aged eighteen, Sawada 'Tsuna' Tsunayoshi (alias Kit of the Young Lion of Vongola, alias Defeater of the Terrible Xanxus, and also known as the One Who Tamed the Pant-soiling Hibari and the Nightmaire-inducing Rokudo of Vongola. Yeah, so many pseudonyms, and the list did not end here… It was slowly gaining in length as time passed.) was slowly taking over the Vongola Famiglia, with Nono still holding the mantle but preparing to let go of his title and passing it to the next generation. He was cleaning up the Underworld, taking away first the ones who dealt with crueller practices like child prostitution or human trafficking, though there would never be total purge of nefarious deeds. Mukuro was overjoyed to be able to make the Mafiosi 'take some well-earned vacation'. Their minds were completely blank when they returned from their little trip with the Owl of Vongola.

The young brunette read attentively the papers in his hands. The kidnapping cases were all done in the same fashion and with specific categories of victims. That's how the Vongola was able to keep track of the intriguing affair.

He shook his head in refusal. He had heard of what happens to young children when they went with some stranger at odd hours of the night.

The man growled in warning.

The targets were always pre-teen males, having about the same built and colouring, black hair and blue or green eyes though there was occasionally brown eyes. The perpetrator was deduced to be obsessed with these boys, most likely to be a sexual predator. There were witnesses declaring they saw the kidnapped being accosted by some shady men, without any particular physical or mental traits and links to the mafia, and brought to a shaded alley for them to disappear altogether afterwards.

He took a cautious step back. He did not want to get into trouble, and the man before him reeked with it.

His actions only served to anger the man. A savage snarl contorted his face, making a grotesque imitation of a human's face.

He was preparing himself to scream for help right now.

Weeks later, each of the boys reappeared in the scientific domain as test subjects of some till then unknown scientist – some man called Fipherpol Romain - to vanish completely after around two months. The Vongola did not get involved, since everyone was panicking over the yet to be named Tenth Boss of the prestigious and deadly Vongola Famiglia.

There was a group of suspects who were likely to be related to the situation; however, the one who was the most noticeable was a French obstetrician, a certain Nésanglatté Aldéric, newly introduced to the darker society lurking on the border of what was considered as the norm and beyond. He was the most suspicious, because it became known that he worked together with Ficherpol before his recent death. Not much of information was gathered on them, and it greatly bothered Tsuna.

"Shut up! Imperio!"

But… Tsuna was finally the -rather reluctant- boss. He could do whatever he wanted to as long as he did not attract the attention of the Vindice. So there he was, sending Gokudera for a new errand, and that was it.

Who knew it would bring so many problems inside the Famiglia? However, it was not unpredictable, with everything which came with doing damage control for the Underworld with such a Family.
