CHAPTER FOUR: The cloud's storm. Rain helping another rain. Sun and lightning on the way.


Hibari Kyoya was on his patrol when a bunch of herbivores appeared and started ruining his peace. Needless to say, he was not happy at all. "For disturbing the peace in Namimori. I'll bite you to death." And so he did and the herbivores didn't stand a chance to him. He took a glance at the bodies on the floor and started leave when another herbivore appeared.

"Hibari-san! Let me be your underling! I will also protect Namimori!"

Kyoya stared at the herbivore blankly, letting out a "Hn" to the herbivore. "My name is Kusakabe Tetsuya." Kyoya took his sweet time assessing the herbivore, he pondered for a moment of what would his little animals would think of this and mentally shudders; there is no doubt that they would laugh at him. "Herbivore, don't call me that." He turned around and started to walk, leaving the stunned herbivore not before he called him out. "What are you waiting for."

Tetsuya gasped as his eyes widened in shock. "Hai! Kyoya-san!"

Later that day, Tetsuya didn't know whether or not he is dreaming as a bunch of kids his age talk to Kyoya without any sort of formalities. He heard about there are few people that Kyoya tolerate but he didn't expect people his age and to this extent. Soon, he will know that the kids are as insane as the skylark.

Kurokawa Hana doesn't tolerate nor like monkeys. Monkeys include those kids in her school apart from Kyoko, Tsuna, Fran, Rasiel, and Kyoya (she didn't really know Tetsuya that much but he is tolerable) and those stupid people in their town. However, bless her as Tsuna and Kyoya's trouble prone magnet suddenly latched onto her decided that it is a good idea for her to clean up with some monkeys in her class. Excuse her but she can clean it herself without needing any sort of help from monkeys.

"Help has arrive!" Hana is horrified and glared at what she recalled as the baseball monkey. "I don't need help." God, why did she have to be separated by Kyoko, Fran, and Tsuna's class. She have to deal with monkeys alone without those three. (Hana idly remember that she got so upset at the start of the year because of the class arrangement and Kyoya have to dragged her to school. The skylark does not like any lazy herbivores in his pack, apparently).

"Nonsense! You can't clean this all by yourself." The baseball monkey laughed then smile at her. If Hana isn't a composed girl, she would have thrown a tantrum now. All because of this baseball monkey smiling so fake at her as if she didn't notice it.

"I can. I don't need a monkey helping me."

"But I am a human." There, he smiled again. One more time and Hana is going to let her mouth do what she wanted to say in the beginning. "Come on." That was the last straw for Hana.

She stopped sweeping the floor, staring at the baseball monkey who is cleaning the board. "Look, if you want to help me. Stop smiling like that, baseball monkey. If you aren't happy then don't freaking smile, the world isn't going to end if you don't smile." The baseball monkey stop, he turned to her in surprise before he was about to cover himself up, Hana beat him. "Don't ask what the heck I am saying because you and I know about it. I have already deal with monkeys trying to fake their excuses and smiles in the past, you can't fool me nor my friends."

Hana narrowed her eyes at the baseball monkey. "I am not going to sugarcoat anything because I ain't good with comforting unlike some of my friends, mainly Tsuna. If you keep on trying to please others, you're going to close your own sense of worth. Be yourself for once even if people are going to hate you for it." She snorted with a fond look at her eyes as her narrowed eyes dissolved. "Tsuna told me to tell you that. That cheeky guy must have known that I am going to talk to you soon."

"...He...was the one who-"

"Yes," Cue Hana's eyes roll. "That damn guy has a habit of knowing if something is about to happen." She went back to cleaning, dismissing the baseball monkey's confused look. "So, if you want to thank someone. Thank Tsuna. I supposed that this is a way of him saying that he wanted you to be our friend." The baseball monkey let out a gasped. "Although, you need to make sure that you aren't a monkey anymore first before we accept you."

As Hana pursuit Takeshi, Tsuna is on his to the next one. The one is rather... to say the least, driven and passionate. He mentally sighed, he have enough friends like this one but it could never hurt to add more. Besides, this is a fighter and Kyoya would like those ones or so Tsuna thought he did.

Wait, did Tsuna said 'one'? Ahhh, he mean 'two'.

"You're Kyoko's friend to the extreme!"

"Your sister's friend?"

"Yes to the extreme! She extremely told me that he is like an extreme twin to her!"

Tsuna could feel his ears aching from all the screaming. He should have known it is Kyoko's big brother, Ryohei. Of course, he didn't forget his friend, Mochida Kensuke. The two held an unlikely friendship as the former likes boxing and the latter likes kendo. But, he supposed that makes their friendship unique. (Also, what is he saying? His own group of friends is very eccentric too).

"Sasagawa-senpai, Mochida-senpai, good afternoon." Tsuna greet with a smile. "Ah! You're Sawada, right?" Kensuke asked as he waved his hand to the younger boy. "Sawada to the extreme! If Kyoko treat you as her twin, I will treat you as my extreme younger brother!" Ryohei told him.

Kensuke grimaced but laugh however at his friend's declaration. "Careful, Ryohei. You might scare him."

"I extremely will!"

Ah, Tsuna mused this is why their friendship works. Mochida Kensuke acted as the sense of Sasagawa Ryohei's sense. In simplier terms, the two compliment each other well.

"Say, senpais." Tsuna called them out while the two older boys stared them in curiosity and eagerness. "Do you want to fight bad guys?"

"Eh?"

"What to you mean to the extreme?!"

"Well." Tsuna started as a grin slowly forming on his face. "Along with Kyoko, Hana, and Fran with Kyoya's constant assistance and Shoichi and Rasiel's minds. We have formed a small group to exterminate any sorts of bad guys. To put simply, we are serving them what they deserve." Now, Tsuna smirked as he eyed the two. "What do you say?"

Kensuke tilted his head, this wouldn't that much of a big deal ain't it? Soon, in the future, Kensuke would laugh at his self for thinking that -- he should have known that looks could be deceiving. "Sure, why not." Also, in that future, he would also smile fondly as he think of the things they have gone into.

"I will extremely join you guys!" Ryohei exclaimed, punching to his fist to the air. He is already excited as things will started to get interesting from now on. In the future also, Ryohei would extremely be proud of how everything they have accomplished turned out extremely well.


CHAPTER FIVE: Furious mists is not to mess with, hell will come.


Shoichi is terrified, he is at Tsuna's house hacking through something that Tsuna asked him to do. Looking through what he had seen, he is disgusted while his stomach hurts a lot more. "Shoichi? What's wrong?" Fran stepped into Tsuna's room, sitting down next to the red haired boy. "F-fran, don't look!" Shoichi panicked, shoving the boy away from him as he tried to close the tab.

Shoichi knew that despite Fran's apathetic front, the boy have experienced traumatic events in his life before Kyoya came across him in the streets at France. He knew better than to let Fran know about what he had seen and read.

"Shoice? What's wrong? Did you get caught? Me can help you as always. Tsu-nii must have told you to do something difficult." Shoichi shudders, difficult it is, and eyed his laptop one more time before turning to Fran and giving the boy a forced smile. "No need. I'll be fine." Fran furrowed his brows as if he didn't believe Shoichi's lie. "You know, Me can see through lies. Just show me."

"I can't! Tsuna and Kyoya will be mad if I did! Heck, even Kyoko!" Shoichi exclaimed.

"Just show me." With a blink of an eye, Shoichi found himself at Tsuna's bed instead on the floor in front of his laptop. "What?! Fran! No!" Shoichi tried to stop Fran from seeing the tab but failed to do so when he notice that Fran's eyes widened. "This... this is why." Shoichi whispered.

Fran turned to Shoichi, eyes pleading the latter with resolve. "We need to help those children."

"We will." Tsuna's voice rang throughout the bedroom gaining Fran and Shoichi's attention.

"What?!"

"Tsu-nii, really?"

"In a week, we have a week. Shoichi and I will gather information." The two boys noticed a phone on Tsuna's hands is enough for them to know that the others are listening too. "Kyoya, Tetsuya, and Kyoko would inform the Japanese and Italian embassies about this. Ken-nii and Ryo-nii will be on stand by and call some orphanages if there are a lot of survivors. Hana, Takeshi, Rasiel, and Fran will be the one's to operate" Tsuna flashed them a sincere smile.

"Tsuna?!"

"I'm going? This is going to be exciting!"

"Hn."

"Hai! Tsuna-san!"

"Extreme!"

"Onii-san!"

"I'll keep Ryohei in check then."

"Ushesheshe, the prince will save some peasants."

Tsuna cough to regain their attention. "Now, let's get started so we can save the kids in that awful place. And, Kyoya -- the underground district is already yours." Kyoya let out a pleased "hn" at that. "Shoichi will take care of it after this operation." Shoichi glowed in excitement, for a moment, forgetting about the operation.

Hana grumbled in annoyance, Takeshi smiled sheepishly, Rasiel frowned as Fran navigate throughout the laboratory. "This way." Fran pointed at a hallway. "We need to get back at Japan before night time, we need to hurry up." He added to them and the others nodded at them.

Once they reach a room upon the approval of Tsuna from the earpiece they are all wearing. (Shoichi and Tsuna are at Tsuna's place, acting as the guides for the four). They were welcome by children's bodies on the floor, all of them mostly dead. "What." Hana scowled, a disgusted feeling in her gut as she stare at the sight. Takeshi composed himself, taking a look if there are any survivors. Rasiel decided that he will guard from the outside to make sure no one knows about them.

Fran gulped unknowingly. "Is there anyone who can hear us?" He called out. "We are here to help." He uttered again in hopes that there are some people who survive.

To their joy, there are survivors.

"You're here to help, byon?"

"Ken, not so loud."

Takeshi smile in relief and was taken back when he saw the two survivors. He knew the laboratory experimented on children but he still couldn't believe what he is seeing. Still, he regain himself and run towards the two survivors. "Yes, we are. Do you know any survivors?" He help the two, along with Hana, to stand up.

"Mukuro-sama is in the experimenting room."

Fran's face hardened at that. "The four of you stay here. I'll make an illusion to make sure no one will go in here." He turned, making his way to the door. "What are you planning?" Hana demanded.

"What we needed to do." Fran didn't looked at Hana but it is clear that he is furious. "Serving them justice just as what Tsu-nii wants." Hana sighed, she knew there is no stopping Fran from whatever he is planning. She also knew that Tsuna put them all together for a reason and for whatever reason that is, she didn't know.

When Fran left with Rasiel, Takeshi and Hana took care of the two survivors with first aid. "What are your names?" Takeshi asked, curiously at the two. "I'm Takeshi and this Hana." He introduced themselves as he carefully bandaged the wounds of one of the survivors. "The other two are Fran and Rasiel. Fran is the guy we walked in here before and Rasiel is the one who is outside." He added.

"Ken, byon."

"Chikusa."

Hana sighed. "How did you get in here? Those monkeys are disgusting."

The two looked at each other before Chikusa speak up. "We... we didn't know." Hana frowned at that but she decided to let it be. "This is mafia, you know that, right? You guys might get killed." Chikusa added.

Takeshi choked, Hana wouldn't like this.

"We won't. We manage to put down the yakuzas in Japan, what makes you think we couldn't take care of mafia." Hana frowned before her lips turned into a sinister smile. "We came here prepared to take any survivors with us and to take down this place. And to answer your question, yes we do know. But, do you know we are Atrocious Justice?" Takeshi grinned at the last part, "So don't worry." he finished.

Hana glared at Takeshi, "Don't act like a monkey." the latter laugh at her.

"A...at...atrocious justice?"

"Byon?"

"Man, you guys will know soon."

Rasiel pursed his lips together, eyeing the furious mist with him. He could somehow relate to him, after all, his twin almost kill him if aren't for Kyoya arriving just in time to save him. However, fair enough, he also did try to kill his twin but to some extent -- he wonder what will his twin reaction when he learn that he is living well and good, Rasiel would laugh at his face.

But, this. This is different.

After spending years with Tsuna and his friends, he learned to value life and have morals to be proud of. Generally speaking, if he had stayed in that castle as he grow up, he wouldn't learn to appreciate the beauty of friendship and family (his twin is a different matter, the guy tried to kill him!).

This is just inhumane, how can these humans look at children as a test subjects awaiting for their deaths if they didn't survived their experiments. That's why he couldn't bring himself to go to the room alongside the three, because he couldn't take off the sick feeling that he had once look at others as some sort of things waiting to be smashed.

However, this is just different. Even if he once think of that way, he couldn't -- Rasiel could never ever use humans, much less children, as sort of sacrifices for the sake of development and science.

No, even if he is a terrible sinful being, this is just too much.

The children don't deserves this. Those innocent children who held a future once but was taken away from them because of these scums.

Rasiel would make those scums pay. As Tsuna said to them, "Justice shall be serve."

XXXXX

Fran would say something annoying to Rasiel because the so called 'prince' is oddly quiet and serious. But, this is a serious situation, he couldn't bring himself to tease the older boy because he knew Rasiel is furious too.

There are two survivors, three if this Mukuro survived and Fran hope so. He could feel the mist's distress as they walk, looking for the experimenting room that Mukuro is in. Tsuna and Shoichi are both quiet, odd in his opinion but given to the situation at hand, he concluded that the two are already contacting the others to make sure everything will sort out just fine.

Fran is an apathetic boy, he doesn't show his emotions that much and he always give some snarky remarks here and there. But, he means good -- his family knows that fully well. So when he lose his cool when he saw the tab Shoichi's clearly trying to hide from him but failed to do so. Something snapped at him that time, he recalled the times his own mother would lashed out at him -- insulting and harming him, he couldn't let those children die (especially, when he knew he can do something). He couldn't.

Fran frowned as he feel the mist's calls for help. After Rasiel had explained to them about flames and Shoichi's research (hacking) about the flames; Fran kinda have a gist of what he is feeling. He needed to get to Mukuro fast before something happens.

"Fran. Rasiel. Stop. That's the room."He snapped out of his mind and look around like Rasiel, once he could feel the flames of Mukuro -- he turned to Rasiel who seem to have the same idea as him. "You'll take care Mukuro, I'll take care of the scums." Fran nodded, coating the male with his mist flames to sure he is protected.

Fran turned to the door, opening it without anyone's knowledge (besides Mukuro) and slowly he manifest his flames to make an illusion that could harm the scientists' mentally. After doing so, he rushed towards Mukuro, removing the things around him carefully. "Fran, you arrive just in time. Don't worry." Fran smiled softly at Tsuna's assurance as Mukuro began to stirred up. "Who?"

"You're safe now." Fran stated, his eyes darkened at the scientists' and Mukuro followed where he is looking at and sighed. "Mukuro-san, don't you want to kill them?" Fran tilted his head, a glint on his eyes is enough for Mukuro to know that Fran is leaving the scientists' up to him.

"Who are you?! What are you doing here." One of the scientists screamed at Fran to which Mukuro rose a brow, he is also curious to the boy's identity.

"Justice shall be serve by Atrocious Justice."

In the future, Mukuro didn't expect that this group would be the one he would call a family -- he will laugh at himself at the irony that he promised himself to destroy mafia once when the group is greatly feared.

However.

This is the present, Mukuro killed the scientists without a second thought as Fran watch the whole scene. Once Mukuro is finished, he turned to Fran. "You're japanese." Mukuro pointed out.

"Ah, no. I'm actually a french but I live in Japan."

"Atrocious Justice, isn't that the group called a force located in Japan? Fighting for the right? And it is manage by kids like me?" Mukuro curiously questioned.

"Yes, we are. Most of us are kids -- all of us are. Tsu-nii is the boss, although he doesn't like being called as one. The oldest is at the age of twelve and the youngest is nine. If you're planing to ask me about my age, I am nine." Fran answered quickly.

"Now, we still need to kill some scientists."

XXXXX

Rasiel was left dumbfounded when Fran and Mukuro first got his preys. He immediately regain his cool and turned to Mukuro. "Ushesheshe, peasants that scums are my preys."

"Ma, ma. Rasiel-nii, let Mukuro-san have his fun." Fran told him.

"The Prince-"

"Fake Prince."

"You dare-"

"Fake Prince."

Mukuro watched at the scene in front of him in confusion and amusement. They have already finished killing all the scientists and they are on their way to Ken and Chikusa who are with Hana and Takeshi. Then, he stopped walking. "What about the Vindice? The Mafia Police?"

"Ah, that." Fran said out loud.

"The files are with Hana, right?" Fran said again.

"It is." Rasiel confirmed.

"What files?"

"Files to make sure you three and us four aren't going be in prison."

XXXXX

"Mukuro-sama!" Ken yelled in relief.

Hana rolled her eyes and put her arms in her chest. "We need to wait for those Mafia Police and give them this files that Tsuna asked us to bring." Ken and Chikusa freezed at the mention of Vindice and looked at Hana as if she is crazy.

"Guys, stay alert."

The four shifted at Tsuna's warning and on sync, the Vindice appeared. "Takeshi." Sky flames coated the kids, it came from a box that Tsuna gave Takeshi to open once he called his name so he can protect them.

"You kids." Hana took a deep breathe and hand Fran the files. Rasiel went on the front, ready to attack. Fran clutched at the files tightly.

Chains appeared, quickly make its way to them when a dash of flames fired it away.

"Tsu-nii!"

"Tsuna!!!"

"What are you going here?!"

"Tsuna!?"

"Let's say, I follow you guys because I am worried." Tsuna smiled at them as he turned to the zombie-like members of Vindice. "We are Atrocious Justice." His gaze turned cold, "If your laws is for the balance of the mafia then tell me why are innocent children like them are being experimented. Your laws are nothing but to make sure you are all feeding your egos and blaming a bunch of kids for killing a Family. You are all hypocrites." His sky flames lit out much more than before. "These are the files," He gestured Fran to give him the files as he throw it to one the members of the Vindice. "That would implied that all of us are innocent."

Silence filled the throughout the room.

"You dare to defy us." The room have gotten colder than before. "Mafia isn't-"

"As Atrocious Justice too. We merely have afflictions to the Japan but that is all it. We work for justice." Tsuna stated. "Even if we are just children, I don't think that is enough for you to think lowly of us." He added as he sternly stand in front of Vindice. "I am Sawada Tsunayoshi, as a representative of Atrocious Justice, if you dare to say that this is your justice-" Tsuna was cut off by speaking.

"Of course, a descendant of Vongola Primo. He was one of the few that dare to say their pride." There was paused. "To think that his descendant would do the same."

"V-vongola? What?"

"You didn't know, ironic. We will let this aside because your ancestor is one of the few we respect."

"They disappear! What!?"

"Tsuna?"

"What the hell is that?!"

"Tsuna, get a hold of yourself!"
