The chaos started where Nautilus had to fight beyond the flame haired Tsuna.

The one that had pulled Neurons away from the danger - green straight hair that cut mid-neck, dull grey eyes, a boy - set the midget on the ground. He turned facing the fight that was occurred before him, guarding his master from being attack by their enemy.

Four men against Nautilus; two bulky and others slender. Three women against Tsuna; different weapons in hands - claws, staff, samurai sword. Two kids; A boy and a girl - black chains connected with shape like daemon.

A brief observation made as Reborn forced himself jumped out of a way before the child girl - short light brown tied in high ponytail, dull green eyes - able to whip him with her chain. He flipped mid-air then landed softly on the floor. Not a second later, he moved quickly to the side and the desk behind him exploded into splinters along the rest of the objects on it. Reborn would have felt insulted that he had to fight children had not he knew the dread situation.

There were a lot of things Nautilus's master could do. Reborn wasn't sure what bullet he could use because Nautilus's master seemed to know about all the bullets Reborn used. It was a good thing for Reborn when his gadgets failed he could punch his enemy as hard as he could.

Reborn was Tsuna's and Nautilus's last hope if they fell against anyone who was bad or wanted them dead.

Blocking the staff that was meant to knock him down with both palms Tsuna backpedal before his abdomen got clawed.

A glint from above and his flaring Hyper Intuition was enough to give him a warning of danger as he sidestep from slashed by sword.

The sword wielder landed beside the brunet, instantly slashed upward. It would have cut the sky user, if the said boy didn't duck and kicked her stomach, causing the girl skid back onto the floor a few inches, stopping right next to her groups' feet.

The girl was in pain and very angry when the boy kicked her in the stomach.

Tsuna watched the claw wielder -red wavy hair tied in low pigtail, pale blue eye- darted forward and made her move on slashing at him repeatedly. Each time, Tsuna was able to dodge from getting hit. He dropped down, avoid from getting cut into two, at the same time sending a roundhouse kick. The girl caught of guard and fall back.

Just as the claw wielder hit onto the ground, he was once again assaulted by staff wielder -dark grey hair tied in braid, purple eyes- from his left. Without giving a second thought, he grabbed the staff and pulled forward along the girl, kneeing her before releasing the other.

He didn't have the chance to watch the staff wielder crumbled as he flipped into the air, the slash cut through the air where the brunet once stood before. He watched as the slash damaged the wall deeply. As soon as his feet touched the ground, he bended backward, letting the sword swung passed above him. Using a handstand he threw a kick upward. The kick hit the wielder's hands -Dark blue long hair, yellow eyes- loosened her grip. The sword flew to the side, leaving the girl weaponless.

The first thing the girl knew being weaponless was she couldn't hit someone with a sword using her fist. That's why Tsuna was surprised when he winded up, feeling a fist buried into his stomach before the girl sent an uppercut followed by roundhouse kick into his torso.

'Damn,' Feeling his body crashed into the wall, his head spin in dazed, 'that hurt like hell.' He thought as the girl darted to the side grabbing her sword.

The girl was happy to have her sword back. She raised it in the air and turned it around to show how happy she was. Well, as much as happy the girl looked with her blank face. Her body language however contrasted against her outward expression. This girl was really eager to sometjing about it. Correction: This girl was really eager to cut him into pieces.

From the corner of his eyes, the claw wielder and the staff wielder appeared behind him, ready to attack.

He was besieged.

'Great.' Eyes narrowed, lips pulled in firm line. Eyeing the weapon pointed dangerously at him warily. 'Just great. I just have to fight weapon wielders.'

Nautilus's situation wasn't any better than Tsuna.

Rounding him liked a trapped animal was the male subjects. The male subjects has many powerful traits and powers that made them one of Nautilus's greatest foes.

Each pair facing against him. In front of him was the first bulky guy - bald, black eyes, had goatee - raising his bare arms; since his long sleeves was torn, unlike the rest of the subjects. His thin partner - long black hair kept covering his whole face, unable to identify his eyes ' color- slouched down with his arms limp in front of him.

A glance at his back shown him the pair in the same stance with different people. The second bulky - brown cropped hair, red eyes - and his (second) thin partner - short crimson red hair, blue eyes - watched him like hawks.

It was hard to fight against them not knowing their names and their abilities. 'Oh well,' Nautilus shrugged mentally, 'I'll just give them name then.'

The first pair, bulky as Baldy and his partner as Ghost. The second pair, bulky as Browny and his partner as Bloody.

Baldy was the first person to run up to Nautilus ready to punch. With electric sparks going through his eyes, his fist connected into Baldy's jaw first. In all of Nautilus's fights that was the weakest punch he ever tried, but apparently it seemed to hurt Baldy.

Ghost really did move like a dead person with a long hand reaching out. Ghost slipped his hand away from Nautilus's eyes and punched him. He was fighting better than Baldy. Nautilus roundhouse at Ghost, but he couldn't get one foot up when Ghost squeezed his throat.

What most surprising was, the grip around his throat loosened, giving him a brief to breath. He choked suddenly when the grip came back in full force, only this time something snaked around his neck and tightened.

'What the hell!?'

Clawing furiously at the dreading unknown he scanned at the source of his painful torture.

Arm.

Stretching arm.

Wounded up around his neck choking him. Following the stretching limb he finally caught the suspect.

It was Ghostly.

Upon moving around, his eyes revealing its colour - yellow with snake like eyes.

Nautilus immediately changed his name from Ghostly to Snake. It fit his appearance well.

This guy was hard to hurt but he wasn't strong enough to take Nautilus down. Nautilus was sure he could beat Snake with just one punch through the jaw.

But first...

The Snake was rigid, and the next thing he knew he got pulled across the side. Before he recovered, his left cheek stung painfully.

As soon as the grip loosened, Nautilus quickly throw Snake back to his partner, who just rose up from his fall and caught Snake.

Snake was powerful he admitted that. But he's power cannot withstand Nautilus's.

Snake wasn't immune to lightning after all.

Nautilus was by far the greatest person to use electricity in his hand. No other person could use an unlimited amount of electricity because they were subjected to inhuman tests.

Sensing the incoming danger from behind, Nautilus ducked. A strong swift of winds passing his head before the floor before him exploded.

He looked up as the smoke cleared, and found Browny, now dubbed as Metal since his whole left arm changed into metal, stood in the crater.

'Damn,' His forehead started sweating, 'Metal's are suitable as lightning conducting rod.'

Metal turned round and charged with his metal arm raised.

'Which mean this guy won't feel any pain of being electrocuted.'

Nautilus could only try to dodge Browny's metal arms. One blow delivered by his metal arm was enough to crack Nautilus's jaw.

Without any warning, explosion pain surged through his body, much like how kangaroo champion did against its opponent. A flash before him and found Bloody appeared in the mid-air before throwing a punch - not as powerful as Metal but still packed enough - at him, causing Nautilus knocked back into crater with a bang.

'No longer called as Bloody. So, that would be Flashy then.'

Nautilus groaned in pain.

The pain of falling into a crater wasn't just how it felt during impact but how when he stood up something small but painful was in his body like a splinter string.

'Yup, Using speed to distract me from catching him and not get electrocuted.'

That's where he felt something dripping down to the ground from his body. Smell of copper entered his nostril and he grimaced.

Blood.

He checked his body - still in pain - for confirmation, and once again he groaned.

Most of his body part had small but certainly deep holes with blood still pouring out .

'No punches can give such injury on people.'

Nautilus, ever average pace, raised his body up into sitting position and took a scan at Flashy and to his hands. His left eyebrow twitched.

'Correction: No ordinary punch can give such injury on people.' The man thought as he eyed warily at the spiky black glove adorned by the enemy.

Thankfully, Nautilus was not just ordinary as other people meant. He was once the same as them after all. He was suited to any attack the people in this base could hit him with. He could brace heat, push back energy balls with his electric hands, and never get on his knees to beg his enemy to let him live.

There were only moments he felt like he could still breath before their punches took the breath and blood away from him. He painfully stood his ground as he panted. His eyes met the Baldy's.

'At least I now know what to expect. The three of them, anyway.'

While guarding up and ready to go defensive, he took a rasp but steady breath.

All he had to do was ignore the pain about to go into him and he would be fine.

The second his thought life left his mind, he leapt to his right. Something big and heavy crashed at the spot he stood not long ago. When he looked back, a tan wall blocking his view.

Nautilus moved three steps away from the wall and analyzed.

' That's definitely not wall. That's an arm!'

Forearm was the right part of limb. A giant forearm, bigger than Nautilus's body.

He watched where the limb connected until it led to the last subject of these four opponents of his.

' Shit! Giant is proper name for Baldy then.'

Nautilus knew the only place a giant could feel pain against a small fry like him was in the eyes. The eye was the closest part to his brain. The moment Nautilus made contact with the eye it would feel like he was being punched in the brain.

All Nautilus could do was backflip. All those times Nautilus practiced being a flexible hitman paid off. One hand stretched out to grab him but Nautilus kicked the hand after he jumped over it. He kicked the person attacking him twice. One was just a kick down on his hand and the next was a roundhouse kick.

Nautilus couldn't get enough of this fight. While dodging, he catch a glimpse of his group fighting against their own opponents. This fight really doesn't look fair at all.

Reborn leapt out of the circling chain before it could shred him into pieces. Ducking under the shooting chain while darted forward, the infant/man loading something into his Leon pistol.

'Time to end this game.'

Running zig-zag with a blur around the retreating chain, he jumped on the little girl's shoulder and pulled a shot in her neck. The girl child instantly dropped down unconscious along her chain.

With a grace liked a cat and a speed liked a panther, Reborn leapt on the boy as soon as the boy's partner hit the ground, catching the other off guard (beyond that blank face).

He shot, the same way he did to the girl. Instead of hit, it missed by several inches with him twisted his body to the side. Damn the boy knew not to fall for the same trick.

Just as the boy prepared to whip out his chain, something pinched his neck, numbing his body before a blow hit his nape, making him lose conscious and face met the floor a little bit of pain.

Reborn rose up from his landing on the floor and fixed his fedora. His eyes stared at the fallen kids with unreadable expression.

Always made sure to have a backup in case the first plan was backfire.

Tsuna really, really starting to have a major hatred to pointy objects.

He was talking about the spikes that almost went through his arms. Tsuna didn't know who threw them but someone threw spikes made of metal through his arm. The spikes were close to hitting his chest but his arms protected him from the spikes

Was it Nautilus's former boss who struck a spike through Tsuna's arm? It was in fact, the boss. He did it while his lower subordinates watched him.

Tsuna couldn't move. When he turned his eyes to the other boss, the said man smirked.

" Tell me kid, why can't you move? If you can't move you'll die!"

Oh he knew why. The brunet was paralyzed. By what and how, he didn't have a clue. One thing for sure, the bad boss had something to do with this.

"Now, now... Haven't you learn a lesson from your parents. You shouldn't disrespect your elders. Especially when your life is in their hand. If you continue your fight, these subjects of mine-" gesturing at the stilled girls with weapon in hands, "-will eliminate you right on the spot with just a snap of my fingers."

He barely listen to what the bad boss sprout about since he was scanned the possibility of his issue problem causer. And his calm orange eyes stilled on the girls weapons.

To anyone, those weapons were clean and beatifically shiny. But, under the future Vongola boss' calculating eyes his sharp eyes caught some glimpse of liquids.

From the corner of his eyes, Nautilus was having a tough time as well. And each of his opponents had some kind of superpower - just like Nautilus. 'Can't call him big guy anymore since there were other two big guys here.'

It was terrifying to Tsuna how he couldn't move just from touching a liquid.

"Well, young man?"

Tsuna send a furious glare at the smirking bad boss. If Tsuna said he hated him then it was overpowered by how much despised him now.

He scanned his self. It couldn't be just through physical touch. The numbing liquid would take half an hour to kink in the effects, but he just started fighting for 10 minutes. Unless the said liquid had been upgraded. (Well, they were scientist for crying out loud.) One of the quicker way was to have a path to reach its destination and start the effect. No path for this liquid would take longer than have a path.

The wounds on his torso must the path for the liquid to enter, if his not so torn clothes and speckles of blood on them indicated any of it.

And now he can't move. Stupid (yet clever) scientist.

Thanked goodness he knew a piece of this info if not for Reborn pounded him to memorize about medical, drug and other sort of stuff. This is where all Reborn taught him came in handy. Mr. Know Everything ( A name Tsuna had for him) told him that anything numbing his body was in his body and could be sucked out. Not by his own mouth, but with a capsule inside Tsuna's mouth.

Feeling the numbing of his body lessened bit by bit. He discreetly took a stance that only some people knew, faking as if he's still under paralyse effect for his surprise attack.

"Oh well," The bad boss shrugged, "Stubborn little boy. I suggest you and you companions to surrender now. If you don't," fishing something out of his jacket and show it to Tsuna, it was a purple (again) remote with red button on it, "you see this?"

Narrowing his auburn eyes, Tsuna kept silent from taking the enemy's bait.

"If I press this button," a sinister smile formed which would have chilled anyone if he wasn't so short "my subjects would go rampage."

Just as he finish the sentence, the remote flung away from his grasp, skidding across the floor behind the enemy, causing the bad boss caught of guard and into shock.

"I don't think so." Heads whirled to the culprit, only to see Reborn pointing the smoky gun at the enemy.

The bad boss stared at the smokey gun, laughing out loud at Reborn. " I can knock that gun out of your hand before you get the chance to fire."
