Somewhere in Italy, Sicily, inside an abandoned building, children of all ages can be seen locked inside cages, like they were some kind of animals.

2 scientists and their leader hovered over a 12 year old boy with blood flowing down from his right eye.

"Looks like experiment no. 69 didn't make it" scientists 1 said, staring at the dead blue haired child in front of them.

"Damn, and here I thought he would come out successful, guess he couldn't take pain anymore" scientist 2 stated.

"And he was one of those who lasted longer, too bad, anyway, get rid of him, now that he's dead he's useless to us" the leader ordered.

Scientist 1 and 2 saluted as they carried out their leader's orders. They began taking off the straps that held down the boy on the experiment table. When the boy was completely free, they took his body and dumped him rather roughly on the pile of dead children.

The leader sighed, "Let's move on to the other experiment, until we find a kid like no. 69, we are temporarily stopping the hell's eye project"

The two scientists nodded and followed their leader out of the room.

In the afterlife, seven souls were watching what was happening. The one who was affected the most was the spirit with mismatched eyes.

"Mukuro-sama"

Both anger and disappointment flashed through Mukuro's eyes, anger because of what those scientists did and disappointment because the boy didn't survive.

"So the me in that dimension didn't make it" he whispered.

"My, oh, my, we can't have Tsu-chan's strongest mist die, you know~" someone voiced in.

All eyes turned to the speaker, "Did you finish visiting the living world, Byakuran-san?" Takeshi asked.

"Mm~ I found something very shocking, buuutt~ I'm not gonna tell, anyway, the mist can't die"

"Even if you say that, the Mukuro in that dimension had already stopped breathing, we can't do anything to save him" Hayato stated.

Byakuran grinned, "Who said anything about saving him? I only said that we can't have Tsu-chan's strongest mist die"

Ryohei looked confused, "Then what do you mean to the extreme?"

Byakuran's grin widened, "It's time for someone to accompany Tsu-chan down there, don't you think?"

Realization dawned to all of them, "You don't mean....." Lambo gasped.

"Yup~ Now, Muku-chan, how would you like to return to the living world~?"

The door to the lab slid open as the two scientists holding a kid each returned together with their leader, "You sure about this two, boss?"

"Yes. I already subjected no. 14 and no. 49 with the possession bullet project and their body took it well, now, stop asking questions and start working!!" The leader barked.

The two proceeded to strap the children to separate experiment tables. No. 14 looked around in fear until he stopped a body he knew very well. "That's...." He trailed off, No. 49 looked at where his friend was looking at only to pale.

His fear turned to anger, that was his friend there on top of the pile of the dead children, "BASTARDS!!! WHAT HAVE YOU DONE TO MUKURO!!!" He yelled.
Mukuro was his childhood and best friend along with his friend strapped beside him, he couldn't believe they killed him and just tossed him away like that.

The 2 scientists scoffed as they prepared the materials for the experiment, leaving their leader to decide wether to answer or ignore him. Being the cruel leader he is, he answered, "Simple, really. No. 69 couldn't handle the hell's eye project and died in the process, he would've made a great weapon had he live"

No. 14  narrowed his eyes and bared his fangs, "HE IS NOT DEAD, YOU MONSTER!!"

The leader chuckled, "Me? Monster? Look at you, your appearance is that of an animal, aren't you the monster here?"

No. 49 couldn't keep silent anymore, "Ken is like that because you made him like that!!! You're the monster here along with your men!!!" he snapped.

No. 14 a.k.a Ken looked at his friend in gratitude before returning to face the leader, "Yeah!! Chikusa's right!! You're the monsters here!!!"

The leader rolled his eyes, unaffected. "You brats should be thanking us that we are making you useful to your famiglia, the Estraneo" he said.

Both Ken and Chikusa glared at him, "We never wished to be born in this sick famiglia nor did we agree to be your guinea pigs!! You damn adults decided this yourselves!!!" Chikusa exclaimed angrily.

"We never wanted to be involve in the mafia in the first place!!! Do you know how we feel seeing our friends die with our own eyes one by one?!" Ken added.

The leader shook his head in a mocking manner, "Tsk, Tsk. You two are so naive, the Estraneo will do everything to become stronger, even if we have to make small sacrifice here and there"

Ken and Chikusa had a look of disgust in their faces, "Small sacrifices?! SMALL SACRIFICES?!! We children you keep killing are from your own flesh and blood for fuck's sake!! You gave us our names yet now you all call us by numbers and treat us like we are not even humans!!" Ken yelled.

"You people are sick, disgusting!!! Every one of you only wants power!!" Chikusa yelled.

The leader sighed, "I had enough of this, commence the experiment" he ordered.

The two scientists nodded and took out the materials they prepared. Ken and Chikusa paled and began to struggle. Scientist 1 walked towards Ken while Scientist 2 walked towards Chikusa, each holding an injection with some kind of liquid inside.

Scientist 1 injected the liquid into Ken.

Ken screamed in pain. He trashed around as his fangs grew sharper and his face began looking more feral.

Chikusa was also trashing around after Scientist 2 injected the liquid into him, though, he didn't undergo the change that happened to Ken, but he can feel something shifting inside his body.

Ken's eyes widened as he coughed out blood, "What's going on with no. 14?" The leader asked.

"His body is acting to the liquid I injected into him, changing his body into that of a beast" Scientist 1 explained.

The leader rubbed his chin, "A beast huh....interesting"

He turned to look at the other who was also coughing out blood, "What about no. 49?"

Scientist 2 stepped forward, "His body is also reacting to the liquid I injected to him. His insides are changing to the degree that he can manipulate any objects, even toys, and turn them into a weapon, if he comes out successful, we will have the perfect assassin in our hands."

The leader smirked, "Not as great as the hell's eye project but still useful. I like it, carry on."

Ken and Chikusa were screaming in pain and coughing out a lot of blood yet the scientists paid them no mind as they worked on their bodies.

The leader watched the two scientists do their work.

15 minutes later, the two children' voices were hoarse due to all their screaming. The scientists were still not finished. Scientist 1 had to hold Ken down after he almost broke free of the straps and go into a rampage.

"How is it?" The leader asked.

"No. 14 is accepting the liquid in his body, he may turn out a successful experiment" Scientist 1 said with glee.

Scientist 2 looked up, "So is no. 49"

The leader grinned, "Good, Very good, boss will be proud of this once we report to him"

"Kufufufu~ I'm sure he will, that is, if you all are still alive to report to him~"

The leader and the two scientists whirled around in alarm. Their eyes widen when they saw the child they thought was dead.

"No. 69!!! So you survived!!!" The leader exclaimed, then, he focused his gaze on the speaker's right eye, "And you acquired the hell's eye!!! This is fantastic!! The hell's eye project is succesfu-" he didn't get to finish what he was saying because he felt something stab him in his chest, where his heart is.

"Oya~oya~? were you saying something~?"

The leader's eyes rolled back as he fell into the puddle of his own blood. Dead.

The two scientists didn't have the time to defend themselves when he lunged at them, his eyes showed hate, disgust and anger but his face was calm and smiling. The two scientists suffered the same fate as their leader.

"Kufufufu~ Enjoy your trip to hell~ Your companions and boss will follow you three soon so you won't get lonely~" he said, pulling out his trident from their body as blood sprayed everywhere.

"Tsk, how messy" he murmured.

He walked towards Ken and Chikusa who were bloody and barely conscious.

"Mu...Mukuro!! I knew...you w...weren't dead!" Ken struggled to say.

Chikusa had a smile on his face, they weren't bothered at the blood on their friend's face nor the fact that he just killed three adults. All that mattered to them is that he is alive.

Mukuro smiled at them, "Of course~ I can't leave you two here in this hellhole alone. Now, rest you two and when you wake up, everything is going to be over" he said, unstrapping them so they can be more comfortable.

The two weakly nodded, trusting their friend's words and gave in to unconsciousness.

Mukuro watched them close their eyes before mumbling to himself. "I need to pick up my precious Nagi from Namimori after this..... or should I visit Tsunayoshi first... Hmmm, decisions, decisions"

He paused

"What am I thinking! Of course my Nagi comes first, Nagi is Nagi no matter what dimension after all, I'll visit Tsunayoshi after I pick her up"

With that decided, he turned to walk out the door with a sinister grin, "Now let's get this over with, prepare yourselves, Estraneo, I am coming for all of you"
