Hey hey! I'm back with another chapter and I stayed up till I could finish it. It's not edited so I apologize beforehand.

Thanks for all the reviews, favorites and follows. I can't believe I'm almost to 150 follows for this story. So thank you!

Enjoy!

Tsuna felt something precious was being taken away from him. There was something missing and he had to go look for it or else he wouldn't feel whole again. Gradually, he regained control and conscious of his body. His eyes fluttered open and he saw a mirror image of himself standing in front of him. He reached out to touch it thinking that it was an illusion but warmth greeted his hand.

The brunet flinched back shaking his head, his eyes widening by the second. It was Natsu. They were similar in appearance, his eyes were a dull sunset orange but his pupils were in silts. It was a sign of a being of demonic descent.

'N-Natsu...Ho—" Tsuna croaked out in disbelief. But before he could finish his sentence his lookalike used his flames to attack the brunet. Tsuna couldn't budge; he didn't want to hurt his other self. There was no way he could.

Hibari immediately noticed the dire situation and grabbed Tsuna's arm and flung him back. He clashed with the possessed Natsu with his tonfas, barely holding his ground.

"Stay back there, if you aren't going to fight, herbivore." Honestly, Hibari was delighted to face off with a stronger opponent. So if the boy wasn't going to do anything he better stay put.

"Kufufu, so the information was correct. Sawada Tsunayoshi had a demon dwelling within his body. To think he would protect you to this extent. It would have been easier if I had possessed you then my goal would have been reached. But this works out too." Mukuro stood up with no signs of injuries. But the only change was one of his eyes were glowing in red and there was a kanji imbedded into it.

Tsuna let out a small whimper how did Mukuro come back to life. It must have been a unique skill. But this wasn't the time to dawdle, Hibari wouldn't last much longer and he needed to get Natsu back. His entire presence was urging him to do so.

"I won't hesitate any longer." Tsuna stated out loud to Hibari. The other grunted in response when Tsuna stood by his side. He would have to go all out if he was to stop Natsu and Mukuro. He'll have to ask for Natsu's forgiveness afterwards for hurting him.

Tsuna fired up his flames along with Hibari and they stood back to back. "Please handle Mukuro for a little longer Hibari-san."

"Hn..." Tsuna took that as a yes and they both flew off. It was simple to lead Natsu away from Hibari. It seemed like Natsu was fixated on him as his opponent.

"Natsu? Can you hear me?" Tsuna desperately called out to him. But the other only responded by throwing punches at Tsuna with incredible speed. Natsu was currently using powerful storm flames but he switched back and forth between the five flames easily. He was adept at using the innate abilities of the flames but for some reason he did not announce any complex spells.

'Wait... does that mean Mukuro can control a person but not their skills...?" Tsuna analyzed the situation. If that was true then he had a chance. He just had to try and keep up with Natsu's pace and corner him. But he could not let his guard down for a second. Natsu swiftly took the chance to ambush him behind. This sent Tsuna crashing through a wall and was buried in rubble.

'I'm actually thankful to Reborn for once for teaching me how to create a shield with my flames.' Tsuna groaned, even without spells Natsu was overwhelming him. The brunet looked down at his gloves that were burning uncontrollably. He was hesitating, even though he told himself not to.

"You're going to die at this rate Baka-Tsuna. A little wound won't kill Natsu. Now beat the shit out of him while you're at it." A voice called out to the brunet. Tsuna looked around but couldn't find the location of the speaker. But he knew who it was. Reborn was right; to get Natsu back he couldn't hold back.

"Thank you..." Tsuna whispered softly, his eyes started to regain its orange tinge. And calmness came over him like last time. Tsuna immediately noticed that Natsu was suppressing the possession and that he was trying to break free from the inside too. He then used his flames to break out of the debris and shot towards Natsu, not giving him a chance to counter. Without stopping Tsuna increased the pressure in his flames and slammed his fist into Natsu's stomach sending him flying. In that mere moment Tsuna closed his eyes and charged up his flames for the technique.

He was riding on adrenaline as he positioned his palm towards the target. He felt sweat on his forehead from the immense heat that was emitting from his flames. He just had to cast the spell and this would be over.

...

...

...

"I can't do it..." His arms lowered to his side, the flames faded away along with it. His will was to protect his friends and family. If he did this he'll be going against his wishes.

Tsuna's eyes blazed in determination and he walked forth to his other self who was already charging at him to land a fatal hit.

"Natsu..." Tsuna projected his voice clearly with a faint sense of regret. He should have trusted his instincts instead of what his vision so that they wouldn't be in this mess. Natsu's body flinched slightly from the voice.

"I won't hurt you anymore." His voice vibrated, tears were threatening to fall. He couldn't believe he had harmed his other self. Natsu had protected him all this time.

"So...would you give me another chance?" Tsuna's voice cracked in desperation. He had to get through him. Natsu was strong enough to break out of this. The brunet could feel hot flames near his face but he then suddenly felt warm tears on his face, ones that weren't his.

A tint of light inched back into the silted eyes of the demon. His mouth began to form words, and muttered a word under his breath. "Sorry..."

Tsuna's eyes widen, he leaned closer and urged the brunet to break free.

"Sorry..." The demon rasped out with difficultly. "—It must have hurt..." The other touched Tsuna's wound on his face.

"I'm sure the punch to the stomach was much worse. I'm glad you're back." Tsuna joked while he clenched his sides that were bruised. It hurt.

Warm tears fell onto Tsuna's shirt while the demon mumbled apologies till the point he collapsed.

"Thanks for everything, and get some good sleep." Tsuna watched as Natsu was enveloped in flames that went back into Tsuna's body. He finally felt complete again and without resting he headed back to Hibari's side.

By the time Tsuna made it back, Hibari was barely standing upright with injuries plastered throughout his body. Mukuro was casually at the other side of the room glancing at Tsuna.

Tsuna was busy focusing on healing Hibari with what minimum sun flames Natsu had left. It was harder to initiate the spell while the other was unconscious. But he managed to produce a small healing spell to speed up Hibari's recovery processes.

"You're low on flames...Really low." Tsuna was concerned, he knew from class that if one is too low in flames their life is in danger as well.

"I'm fine." Hibari kept his attention on both Tsuna and Mukuro.

Mukuro jumped down from the desk he was sitting on, "Oh you're late. That demon of yours surprisingly could suppress my skills. So I couldn't use any special abilities on him. But you didn't get out of it unscathed either which works out." Mukuro quietly laughed attempting to hide his intentions, "Now shall I present to you your next gift?"

They jumped back sensing danger coming near them. Explosions were suddenly heard everywhere. Tsuna gulped, they couldn't be... How?!

"This can't be happening..." Tsuna was ticked off at this point at Mukuro's schemes. If he wanted to possess him or something why do it in such a roundabout way. He had so many questions to ask him. More than anything, he wanted to understand his motive for doing such things.

His guardians and the enemies he saw earlier stood side by side facing towards the two. They all had one thing in common which was their right eyes were glowing in red with a kanji being engraved in them.

"These herbivores are crowding." Hibari spat out harshly, he was getting irritated by everyone here. He wanted to beat them all up.

Tsuna looked to the other and nervously spluttered, "H-Hibari-san, can I propose a plan to you in order to get out of this mess?"

"..." Hibari just stared at the other without muttering a single word.

"U-Um...Contract. So I can share flames with you. Temporary one, just for this fight." Tsuna hastily shut his mouth after.

"I don't bow down to anyone." Tsuna knew that Hibari was a lone wolf. But he shouldn't be picky right now especially when they were dodging bombs, katanas, fists and lightning, plus other arbitrary weapons that the enemies were using. Tsuna was amazed his instincts worked this well, maybe it was a specialized skill for life or death situations because it certainly worked like a charm.

But seriously, nobody should be picky at this point in time. Hibari then muttered under his breath a small incantation. A large purple contract ring spread throughout the ground.

Tsuna was waiting for the words but nothing came out from the raven's mouth. 'What the hell?! Was Hibari messing with him?'

But then suddenly his gloves glowed in purple and a ring floated in front of Hibari. He quickly snatched up the ring and immediately flames flowed into him. Whereas Tsuna could sense a lot of his flames were being drained by Hibari. He had no doubt that Hibari was a very high ranking demon.

'Did he just force a contract? I didn't even agree to anything.' But there was no use in thinking about trivial matters.

Meanwhile, Hibari was quite impressed about the quality of the flames he had received. It was such a large quantity too. He smirked as he went off to face the opponents because he could sense that Tsuna didn't want to fight his friends. He'll do the job for him and he'll even try to lessen the damage.

"Go fight Rokudo. I'll take care of these herbivores that are crowding."

"Kufufu are you sure about that?" Tsuna's guardians and other enemies' irises changed into the number two kanji. "Second Realm: Gakudo, I can properly control these people unlike the other demon earlier."

Hibari just turned around and brought his tonfas up, smirking. "Go." He commanded.

Tsuna followed Mukuro who was currently leading him to another room away from the raven. The brunet knew that Hibari would just manage fine now and he could trust him not to injure the innocent too much. He however could not imagine fighting with his guardians; it would hurt him too much.

But nonetheless Hibari would probably beat him up for interfering in his fight either way. But he was surprised Hibari let him handle Mukuro because he was certain that the boy had a huge grudge on the enemy by now.

But Tsuna would focus on the enemy in front of him. "Mukuro...what are your reasons for fighting?" He had to know or else he wouldn't feel right. Why would he control the Unknowns to invade his hometown? More like why didn't he summon Unknowns now to overwhelm them now? He would surely win.

"I suppose I can entertain you with my reasons. But first, why do you think Hibari was so exhausted?"

"You...Unknowns?! How long had Hibari been fighting them?" Tsuna couldn't believe it. It couldn't be since last night could it? Hibari was battling without slumber when he himself was sleeping without worry.

"He certainly was powerful. Now as for my reasons, I will take control of the Vongola Magic Council. To do that you'll be the stepping stone." Mukuro's eye abruptly switched to a one and the ground started to crack beneath Tsuna's feet. "First Realm: Jigokudō"

"I'll be taking your body Sawada Tsunayoshi." Mukuro stated as the brunet fell through the cracks.

'This...isn't an illusion. I can't dispel it like how Reborn taught me. What did he do?!" Tsuna quickly fired up his flames to stay afloat. The cracks soon were filled with burning lava. He'll have to be careful to stay in the air and not crash down.

"I have gone through the six paths of Hades to get my current abilities. And you'll have a thorough taste of them" Mukuro chuckled, he appeared behind Tsuna and used the blunt end of his trident to impale the brunet, sending him straight to the boiling lava, Tsuna's face was millimetres from it. He used his flames to bring himself back up.

Tsuna flew with lightning speed around Mukuro and used his flames to encircle him. The flames lagged by and this created a temporary seal to keep Mukuro in place.

"Why do you want to possess the Council?" Tsuna was going to hear him out before capturing him.

Mukuro kept quiet and tried to move his limbs but the flames burned him. His eye then switched to a three and Tsuna backed away the instant he sensed something from behind. Several rabid beasts appeared out of nowhere and started to attack him. Tsuna however didn't waver and his calm composure remained as he swiftly took them out.

"Cheap tricks won't work on me, Rokudo Mukuro." Tsuna was irritated; if Mukuro was going to keep this up he would have no mercy.

The taller boy laughed at Tsuna's retort which made the other flinch. Mukuro closed his eye briefly and mist flames started to gather around his right eye. "I guess I will have to be serious with you, since you have a talent for deciphering illusions. We are a bad matchup won't you agree?"

They clashed with Tsuna supporting himself with his gloves he held onto Mukuro's trident and propelled himself up to smash Mukuro's face in with his knee. But the other saw through him and grabbed his foot, "You should be careful, one prick from my trident and it's game over."

"Answer me." Tsuna was no longer bothered with the fight he had another motive. He honestly didn't think this person was evil. He just didn't feel it, call it instinct or a bad sense of judgement.

"Have you heard of the Estraneo family?"

Tsuna recalled some facts from his history class. He dropped his hands to his side and began to think. This surprised Mukuro because he had never seen an enemy be so naive. He could have finished his deed but instead he waited for Tsuna's answer. This wasn't like him.

The Estraneo demon clan was known to be famous for being skilled scientists that were allied to the council. But one day they tampered with forbidden magic so they were prosecuted by the council and other clans. Because of that they did human experiments on their own members to create powerful magic to fight back...

But weren't they destroyed from within, by their own people in the end?

"So that's why..." Tsuna faced Mukuro with eyes that weren't full of pity but understanding. Then, Mukuro must have been the person who killed his own clan. "Were you one of them?"

"...I will take possession of the council by controlling you and I'll cleanse the world of its darkness." Mukuro muttered under his breath. "You cannot stop me."

"Ne, I won't stop you. Instead of that, could I cooperate with you? But um...use a friendlier method. Maybe." Tsuna stuttered he fidgeted with his thumbs. "For example, don't control Unknowns and my friends."

Tsuna smacked himself mentally what was he even saying to the enemy? But it didn't seem like Mukuro's goal was a bad thing. He just had really cruel methods which was understandable for someone with his past. He would probably becoming twisted if he was experimented for who knows how long.

"Don't try and sway me human." He couldn't give up now when he had gotten so far. And why would he even trust such a person?

"I tried at least, but consider it after this battle. Guess I have to knock some sense into you either way." Tsuna calmly replied he was unfazed as his resolution was set in stone. He would have to save his friends first then talk to him after.

"Let's finish this." Tsuna signaled that the battle was soon to be over. It was all or nothing for him.

Mukuro smirked, he would win. He had to, in order to that he'll have to use that. He took the top of his trident off and positioned it near his right eye and stabbed it. "Fifth Realm: Ningendo"

Blood spurted out as the taller boy held his eye, while Tsuna watched wincing. Mist flames started to swirl around Mukuro and the air turned tense with such flames flickering fiercely.

Rokudo quickly cast an illusion spell to distract Tsuna while he ambushed him from the back. But that had no effect as Tsuna blocked the attack with his gloves.

"That instinct of yours, you have honed it well. Not many can see from these illusions."

Tsuna smiled at the other male and used one hand fire himself off Mukuro's attack range. And he started to charge up his flames for his technique.

"Is this the X-Burner? You perfected it so quickly but every skill has their weakness." Mukuro took the chance to attack Tsuna. His attack took too much time to prep up and fire.

But Tsuna just flew off and attempted again which annoyed Mukuro greatly. "That won't work on me..."

At the same moment Tsuna had already noticed that Mukuro was underestimating him quite a bit. He hoped this would work out.

'Of course it will. It's revenge, fucking piece of shit.' Tsuna smiled he was glad and both pleased to have Natsu back. The plan was set.

Mukuro flew towards Tsuna who was preparing his skill and swiped at him but mist enveloped him instead. "Wha—t?" There was no way, he could use illusions? And he couldn't see through them?!

"This will be the end...of your plans. Mukuro, I hope the next time we meet, we'll be allies." Tsuna charged up his fist with pure sky flames and sent the male crashing towards the floor. The brunet flew towards Mukuro and made sure he was still alive before checking up on Hibari. He prayed that everything went well over there too. His guardians shouldn't be possessed by now because Rokudo was defeated.

When he arrived at the location his mouth was agape. Once again bodies were lying everywhere. His guardians and enemies were foaming at the mouth. Tsuna looked at Hibari who was sitting on a nearby couch who was relaxing at the moment.

"Hibari... didn't I warn you?" Tsuna was both frightened and angry at Kyoya.

"Hn..." The boy got up and brought his face near Tsuna's. The brunet was confused and he winced, scared that Hibari was going to beat him up for reasons that were twisted. He felt warmth on his forehead for a brief moment. By the time he opened his eyes, the raven already disappeared from his view.

"What the hell was that?!"

'What the HELL was that?'

Subsequently, pain was felt on his head, "Job well done, Tsuna. There are many things we have to discuss with you though."

"We wanted to help but it seemed that you managed fine on your side. Hibari was impressive wasn't he Reborn?" Giotto commented jokingly.

Reborn nodded but he was surprised with Hibari willingly gave his seal of approval to the contract. Not that Tsuna would know why Hibari did what he did. The other guardians will be jealous once they hear about it though. That would be a spectacle to see. He could already sense Natsu's bloodlust from this afar.

"So, what will happen to Mukuro and his friends?" Tsuna hesitantly inquired, he wanted to know if he could protect them.

"Vindice will come and he will be imprisoned for the rest of his life I suppose. If he doesn't break out again." As if that was their signal, a warp hole appeared before them.

Tsuna knew that they had committed crimes but even so it was self-defence for the majority crimes he committed. His own clan had experimented on his precious friends and Mukuro himself too. He didn't know about the other sins he had done but it couldn't be that bad. Not enough to be locked up in an eternal prison for the rest of his life.

"We are here to retrieve the traitors." A man covered in bandages and a dark cloak came forward.

Tsuna tried to argue back but Giotto had put his hand over the brunet's mouth. "Yes you may."

Reborn sneered, "Do you want be taken away too? Idiot."

Tsuna glared at the both of them while remaining dead silent. He would rescue them if anything sooner or later. He promised to himself.

After the Vindice took their leave, Tsuna was unusually quiet. There was an awkward tension between the three.

Meanwhile, Giotto's guardian Lampo soon used a transportation spell to get them back to the academy.

Soon Tsuna's friends woke up and they were disappointed in themselves because they couldn't do anything in the end. Fuuta was crying in relief when he saw Tsuna.

"What exactly happened back there?" Tsuna was surprised his guardians were not weak at all so he was curious as to how they got possessed.

"We were immersed in the battle so we didn't notice the enemies held small versions of the Mukuro's trident so they cut us while we were fighting them. I didn't know that the trident had a possession enchant. I didn't notice at all." Yamamoto regretfully admitted to Tsuna.

"So when we had beaten them up they laughed and said that we lost too. We soon lost conscious afterwards." Lambo kept his glance away from Tsuna's.

"AND, by the time we woke up everything was over." Gokudera yelled out in frustration, he was useless in the end. And that stupid Hibari Kyoya took the spotlight instead.

"You guys did lots, and I'm thankful for that. Thanks for everything." Tsuna bowed to them, signalling his deep respect for his friends.

The others were embarrassed and told Tsuna not to do that. They were happy that Tsuna was grateful to them.

Reborn then interrupted the conversation grinning in amusement. "Oh and did you know? Baka-Tsuna here got Hibari in a contract, a really special one too."

Within that moment all of the guardians had their eyes turned into silts and were glaring at Tsuna. Their eyes glowed in their respective flames.

"Holy SHIT, no way?" Gokudera was the first one to react. He collapsed on the chair. The other three were too shocked to have a response. Their jaws hanging open including Sasagawa's.

"Um... is there something wrong?" Tsuna couldn't see the point to all this commotion. He was taken aback when Hibari placed a...kiss on his forehead but that was it. Was there some special meaning to this?

"How dare he place a higher level contract than I did? I'm the right-hand man of Tsuna-sama. And it's that contract out of all to choose."

"Tsuna, that contract is rarely used because-" Yamamoto paused a moment choosing his words carefully before continuing, "The demon is allowed free rein and does not have to obey the contractor and does not suffer consequences from it. But in return if the demon does appear beside the contractor when they desire them their respective abilities increase by far.

Yamamoto couldn't believe this. This contract type was a high level contract but it needed complete trust between both individuals which he knew Hibari wasn't the type. If Hibari won't come and help then this contract is completely meaningless and Tsuna would still have to waste his flames to support the other.

"Was that it? If that's so I don't really mind. Hibari is the lone wolf type so I'm not expecting much."

"But Tsuna-sama, you'll be giving away flames for nothing if Hibari doesn't come and aid you. It'll be pointless in this case."Gokudera cried out he couldn't believe this.

"It'll be alright, really. If you guys want you can have the same contract or whatever." Tsuna could sense the frustration of his friends. He couldn't fully understand and they didn't seem to be telling Tsuna the complete truth of the contract.

The others were flustered at Tsuna's direct reply, how could he say such things so easily? "Tsuna-sama, I can't imagine of...-"

Tsuna felt a little insulted; did his guardians have a problem with him? Weren't they always beside him anyways so what difference would it make? Sighing, he told them to forget it and everyone should all rest up for tomorrow.

On the side Reborn was trying to keep himself from laughing. He was dying inside from hearing the conversation. When Tsuna passed by him Reborn playfully whispered by his ear, "By the way that contract, it's rumored to be for people who are in a close relationship. I don't think Hibari nor you know of them but you should get their frustration now."

It was Tsuna's turn for his jaw to drop. What exactly had he gotten himself into?

Later that night after all the commotion, he pretended to not be affected by the comment Reborn made and continued his day. He had absolutely enough, or else he was going to snap. He was going to sleep and not deal with anything until tomorrow.

He soon drifted off to sleep but sadly it wasn't the end of his troubles. He opened his eyes to a sight full of nature, 'A dream...' The brunet thought to himself.

"Oh if it isn't Sawada Tsunayoshi? Have you missed me already?" It was a voice he couldn't dream to forget. Tsuna sighed, even in his dreams he couldn't relax.

"Why in the hell are you here?" He couldn't handle any more stress. He really couldn't.

"I should be asking you that. Nobody should be able to be here except for me." Mukuro was genuinely curious, this was his illusion and no one should have access to it.

"I'm not sure...anyways how are you holding up? I heard about the Vindice." Tsuna didn't know what to talk about he was already pretty uncomfortable talking to his former enemy.

"I'm about to have my subordinates escape in a day or so." Mukuro grinned, "All they want is me so I doubt they'll be looking for them."

"But how about you...?" Tsuna didn't like where this was going. "Don't tell me - You don't have to shoulder the burden all by yourself."

"It's alright; it's not that bad down there. It's just boring. Anyways I can easily get access to the outside world. Don't underestimate my abilities." Mukuro didn't have the will to fight Tsunayoshi as of now. He instead had another idea. "Though, I've got an offer for you."

"Would you look over several of my subordinates? They are named Chisuka and Ken. Soon they'll go back to Kokuyo to wait for me."

"Sure, of course I would." Tsuna just hoped they weren't scary at this point. He didn't mind honestly.

"And I'll hold you on to your promise with helping me. I still haven't cast away the idea of possessing you. But for now, would you like to make a contract with me? It'll be nice to have more power."

"A wha— ?!" But before Tsuna could answer him, a bright violet circle enveloped the ground beneath them.

Mukuro leaned in and Tsuna flinched, dreading what was to come. He felt warmth on his forehead once again. 'Why does it have to be him? Can't everyone just make a kind of ordinary contract like his other guardians?"

The ring fell to the respective demon and Tsuna's glove had glowed with the new addition of a beautiful amethyst gem embedded in it. With this gem, the dents in his gloves were all filled up.

"Hoh... I'm a little annoyed that Hibari Kyoya made the same type of contract. Should I have done something else?" Mukuro's expression could not be seen as his bangs shadowed his face.

"NO." Enough was enough. Tsuna stood up and walked away from the taller male. He had to be thankful that Natsu wasn't present.

"It'll be nice working with you Tsunayoshi-kun." Mukuro inwardly smiled as both went their way. Tsuna couldn't help but be glad seeing that Mukuro really wasn't a terrible guy. He would someday get him outside of the Vindice prison he swore to himself.

I have to say battle scenes are hard.
