The police went to Hashima Island according to Yusaku's desire and from their searching, they found something really unbelievable. There's a hidden underground where inside was a laboratory. There's even a room where children corpse laid in place and many more horrific sight. From their searching, they found the horror of truth, human experiment was taken in place. On what they were trying to achieve, they had no idea.

All files of their work already vanished, only the files of the people they had experimented and labeled dead. They saw one file that's actually unbelievable, a file of an eight years old child named Kudo Shinichi, status dead. The one who found the files was Heiji and the one who scattered to search a certain person was Yusaku. Finding the one he's searching for and truth revealed, the man broke down.

Megure-keibu went to his side, trying to comfort the man who actually lost his son five years ago due to this illegal human experiment. How much the child had suffered in the hands of those people? How dare they choose teens and children for their ambitions! The police are more than furious, they will surely bring everyone here to justice.

By the time they were investigating the island, they got a report a helicopter exploded in the middle to the city. Few civilians were injured due to panic, three unfigured men were found dead inside that helicopter. The cause was someone had used bazooka that put them to death, added there were bombs attached to the helicopter that gived reason for strong explosion and panic to people.

They could only conclude this people must be heading to Hashima Island, throw down the bombs to prevent more findings, destroy the evidence to keep everything from the dark but someone had learned it and prevented them. When Yusaku heard it, he can't help but remember the man in fedora, he could be the one who did it.

The jewel Night Mystery was returned to the owner in the day of deadline, the owner didn't mind to have their place be investigated for the sake of capturing this serial killer and put this to an end. Police headquarters interrogation room, they kept questioning the three captured snipers who refuse to speak anything. They were questioned about what they had found in Hashima Island but still refuse to answer.

In the head office, both superintendent of Osaka and Tokyo were discussing about this cruel case.

"To think we actually have a human experiment happening in our own country." Matsumoto gave a sigh before turning to the Osakan superintendent and asked, "How is your result in your case?"

"We found nothing that could pinpoint the masterminds." Superintendent Heizo answered, "They cover themselves well." He commented in the end.

Matsumoto nodded, agreeing to him. "We're still interrogating them. None of them ever spoke yet."

"They're making sure they never spill a word." Heizo said before asking him, "What do ya plan to do?"

Matsumoto remembered Yusaku's statement about what he had witnessed. The serial killer supposed to be Kudo Shinichi was fighting a man wearing black suit and fedora, the information that man knew something about them. If only Yukasu able to get his face they could search for him. They even tried to use the camera's in the building but found nothing. That person must have clean his traces before completely leaving, like those people.

"Kudo told us the last word he told him they will meet again. When he comes out, we need to make sure he will stay and tell us what he knows about them." Matsumoto decided as the other nod, agreeing him.

Someone knocked the door and heard a familiar voice, it was detective Chiba Kazunobu.

"Superintendent a package arrived, it says it's for you." Chiba-keiji said which made the two narrowed their eyes on the suspicious package.

Soon it was put to his table. Matsumoto asked, "Did you check this package?" Chiba-keiji gave a salute and answered, "Yes and there's no trace of being a possible bomb or any metal sir."

Heizo observed it for a moment before asking, "Plastic bomb?" He asked and again Chiba-keiji shook his head, "No gun powder detected sir. That possibility is negative."

"So you gave it to me because its deem safe." Matsumoto concluded and he answered, "Yes sir."

Matsumoto nodded as his thanks before he began to open it carefully. Upon opening it they were quite surprise to see a small bottle contained red liquid and letter. He took the bottle and studied it, from the looks of it there's no doubt, this red liquid is blood.

He took the letter and it says, More blood sample from that serial killer. Study it carefully this time and do not become a disappointment. There's nothing say who had sent the letter, just a message which unfortunately not hand written.

Well for him he actually twitched from the word disappointment, whoever this guy is he's actually trying to challenge the police force.

He turned to Chiba-keiji and gave his order, "See if there are any fingerprints been left by the sender and give this bottle to our researcher. Tell them to do whatever it takes to find out the real identity of that killer."

"Yes sir!" He took the items and went away.

Heizo gave a deep thinking before speaking, "Do ya think this person is actually assisting us?" Matsumoto wasn't sure, he just hoped to find this person and reveal the truth they seeks.

Agasa Hiroshi's home, the Osakan Detective came to visit and the one who greeted was a fat inventor, Agasa-hakase.

"Oh Hattori-kun welcome." Heiji grin to the professor, "Yo Hakase, is Neesan there?"

"Haibara is in her laboratory Hattori-kun, studying the package that arrived a little while ago." Agasa-hakase answered. Heiji who's taking off his shoes and went in questioned, "Package?"

"Yeah, it contains small bottle of red liquid and there's a letter in it. Saying it's a blood sample of the serial killer and a good sample for the result about DNA experiment. We aren't really sure if it's true or not but knowing you surely you will insist so she began studying them."

Heiji remembered Yusaku's statement about what happened. 'Could it be...!'

Heiji immediately went to where Haibara was located and finally saw her sitting to her computer, full of formulas and so forth. He approached her.

"Yo Neesan" Haibara didn't even need to know who it was so she just answered, "Shut up I'm focusing."

"Ahh s-sorry..." Heiji knew when to back out especially if it's her. She may look a child but she could be really scary. Haibara continue her work until finally speaking, "Fill me up what's happening so I could actually tell where to start."

With that he obligated and began telling what happened in the last heist. Agasa-hakase offered them tea and even listened to Heiji until he finished.

Haibara on her part wasn't really surprise if human experiment exists. Because in black organization it's too normal to use genie pigs to learn the result of the new drug experiment. Well for now, his concern is the professor who took her in to his home, since in that human experiment, the lost child Kudo Shinichi didn't actually became known serial killer but a victim of that horrible experiment.

Agasa-hakase can't believe what he's hearing. Shinichi was experimented by those people and because of them... he's dead... dead. Tears began pouring down and clenched his eyes as he can't stop crying from the pain.

"I... I'm really sorry for giving you such horrific truth. I'm still in shock about the fact Kudo Shinichi we all knew wasn't a serial killer but a victim and dead. We accused an innocent child this whole time and I hate it! We will all make sure bring his death to justice and clear his name no matter what, we will fix the whole damage those bastards had done. I will make sure of it as a detective." Heiji ended his declaration at the same time assurance, knowing the fact this news totally pained Agasa-hakase.

In truth, the first time he met the professor he really can't believe how much he values Kudo Shinichi no matter what he had done. He always prayed and hoped that someday he will change and will always forgive him to what he had done. Now learning the fact, the person he precious already dead, he can't imagine how he feels right now.

Haibara looked down and gave a sigh, 'From everything they had done for me... Looks like I will have to put everything I can to give that child to justice.' She found a determination to do whatever it takes, find the truth in their experiment and give those people a deserving punishment they deserve.

The child turned to the Osakan and asked in whisper, "Does Yukiko-san knew this?"

"I don't know neesan... I don't know."

Somewhere dark, a small group of people gathered. A secret meeting seems about to start.

"I believe I told you no failure." Someone high that could said be the boss said in low tone before throwing a bottle of wine he holds in his hand to someone far who quickly avoided it but never left where he stood. "I ORDERED YOU TO KILL KAITOU KID! NOW LOOK WHAT HAPPEN!? NOT ONLY THEY FOUND OUR BRANCH IN HASHIMA ISLAND, THEY EVEN KNEW THE MAIN RESEARCH AND THE FACT THAT WE ARE ORGANIZATION!"

"Boss I wouldn't have failed if not the interference with that man and as I had reported, the one who brought us out is that man who interfered with us four months ago." The voice of the Serial Killer answered.

"According to our spy inside the police headquarters, what he actually said is true. Kudo Yusaku had heard their conversation and informed what happened." The person on the side spoke in calm and authority.

The person who's pertain as boss gripped both of his hand as he grits his teeth, "That man... that man plan to ruin us." He turned to everyone on the room and gave a cold stare, "Does anyone here know the identity of that man?"

No one dared to spoke or move, afraid to their boss's wrath. The person whose calm answered, "None of us knew him, not even from the outside of the organization. If I could conclude he maybe a foreigner who had come to interfere with us."

The boss sat to his chair and began thinking. Foreigner who could have known their branch in Hashima Island, who had come there...!

The realization drawn near. Five years ago, they found someone wondering to that island who had easily killed their guards with ease. Their security footage hasn't caught this person, not moving away from the blind spot of the camera but they had seen a glimpse, a long raven hair woman.

'Could that woman be the reason?' He thought thoroughly before asking his right man who's been speaking calmly, "The footage five years ago, have you found her identity?"

He shook his head, "We found nothing until now. We search the whole Asia, it seems she's further from here." The boss narrowed his eyes and commanded, "Find her as much as possible. That woman is the sole reason we're found and someone else acting for her. See her whole associates and kill them."

"Yes Boss."

That person left the room. One of them, a built up man who's been quiet for so long began to ask, "What about that man?"

"Find him and kill him, the more he lives the more he'll expose our organization." The boss ordered. The built up man gave a salute and went away to begin searching the one who's been exposing them to light.

The boss turned to the person who's wearing a doctor's coat, he must be the head researcher. "He got his blood sample, is there a chance something will be found as evidence?" He asked in total coldness, a silent say tell-the-truth-or-die-on-the-spot glare.

The head scientist pulled something up to his face, it was a round eye glasses before answering. "My research is perfect Boss, no matter how much blood he took, everything will end his claim be thrown to hypothesis."

"Make sure it is or else everything we had done, the whole research and pigs will be gone to waste." The boss threatened. He bowed his head, "Yes boss."

The boss turned to the serial killer, his top assassin. "You are a shame in our organization." He said cold and disappointment. The serial looked down, ashamed to his failure. He kneeled down and spoke, "What should I do to regain my honor boss."

"Kill that man and bring his head to me, dead or alive."

"As you wish Boss, this time I will not fail."

In a certain place, Shin was watching the news about the helicopter when someone came and saw Reborn coming in.

"Welcome back, I didn't expect you'll know which one will be them." Shin said which made Reborn smirk, "I expect you to give me useless lecture, good thing you finally learned the reality of this situation."

Shin became silence as he curled himself on the couch, remembering the time in Italy where he's been caught up in the middle of the mafia war. He really thought he was about to die but the Chinese Assassin, Shing protected him and witnessed the rest of them killing the people on sight and pushed him away. He doesn't really know what to think that day, until Mysteria the leader of the small group assassins told him something he may never forget to his language for him to understand.

"In the dark world, mercy and value of life no longer exist. To survive it's to kill or be killed. No matter what run or hide you do, ones get involved there's no turning back. My apology for someone like you born in light had to witnessed this. When the time comes, I'm sure you'll understand them. The nature of the dark world, the difference and its life."

He wasn't sure at first until soon he understood. A harsh truth, if you wish to fight against them, the principle of value of life may lead you to darkness and death.

"When everything is over, we'll make sure this will be the last time you will get yourself involve in this dark world." Reborn's word halted his thinking, making the teen looked to his companion who's now preparing his favorite drink, espresso.

"Reborn" Shin whispered as he saw him finish making one and heading to the free couch to sit on. Reborn took a sip before speaking, "Our family give you our promise, they will be the first and last you'll be dealing with... unless you wanted to get involve on your own."

Shin processed his words until it clicked, "Are you talking about what Kaito's dealing with?"

"The organization that snake is in wasn't part of the deeper ones so even the police can deal with them." Reborn told him, "I'm sure you understood what I mean by it." Shin became quiet for a moment before nodding, understanding him. Reborn continued, "However what we're dealing with are part of the deeper ones. Murder are the most necessary to win against them. I know you have a principle about life but unfortunately it's not effective."

"Don't worry," Shin whispered as he burred himself to his knees, "I know."

Reborn studied him for a moment before sighing. He took his phone and began messaging someone.

Next day, Kaito arrived to their place with his cheery personality.

"Shin-chan!" Kaito sing and jumped himself to hug Shin. He smiled to his antics, "Ka-Kaito wha-what are you doing here? Should you be in school?"

Kaito grin, "Well something happened that the class put on hold. Nothing to worry Shin-chan." For unknown reason he's suspicious. Knowing his sharp observation, Kaito immediately spoke. "Shin-chan do you want to head out? Let's go on the date today."

Well that made him blush, "D-date?"

"Of course!"

Shin wasn't sure since outside those people could be in high alert and moving around to find them but Reborn's word surprised him.

"You go Shin, enjoy yourself." Reborn permitted.

"Re-Reborn?" Shin almost yelp in confusion while Kaito grinned wider, "Oh yeah! Come on Shin-chan, prepare yourself because we're going on the date."

Shin still wasn't sure but in the end gave in. Reborn let him after all so maybe its fine. He immediately prepared himself, wearing a good hat and hood in case before meeting up with Kaito.

"Oniisan, Shin-chan and I will be leaving." Kaito informed as he opened the door and Shin following from behind. Reborn crossed his arms, smirking and nod. "Be sure to be careful. Call if something happened."

Shin smiled and nodded, "We will Reborn, see you."

Both left the house, leaving the young adult behind with a huff. Suddenly he heard his phone ringing. Taking it to see the ID caller, he answered.

"Quello che ha impiegato troppo tempo Checker?" (What took you too long Checker?) Reborn asked in almost angry tone.

He heard a broken laugh before responding, "Beh, la polizia e cosi teso dopo aver appreso l'esperimento umano e da quando sono stato coinvolto grazie al gioiello come esca, naturalmente, la sua difficile fare le cose senza di loro se ne accorga." (Well the police are so tense after learning about the human experiment and since I got involved thanks to the jewel as bait of course it's hard to do things without them noticing.)

This made the young adult twitch, "Come qualcuno avrebbe notato idiota." (Like someone would notice you idiot.)

"Reborn che e dura." (Reborn that's harsh.) Checker said, must be sweating before clearing his throat and spoke, "beh ho ricevuto la lista e quello che stai targeting dovrebbe essere questor uno." (Well I got the list and the one you're targeting should be this one.)

Now that made Reborn smirk, "Dimmi" (Tell me)
