Chapter 3 The God of Death and the Hitman Tutor

"The government people are going to need a lot of explaining to do after this." Reborn's familiar and sexy (Tsuna was not going to admit to the fact that he has a man crush on his tutor fully grown) baritone voice said with a frown.

"R-Reborn!" Tsuna addressed.

He looked up at the source of the voice and looked straight into the eyes of his former student. He was a bit glad that he was unscathed, or else, there would have been trouble on both ends. "Chaos, Dame-Tsuna." Reborn said with a smirk.

"Reborn?" Irina muttered as she looked at the man. "He's…he's actually here?!"

"Who is he?" Kayano asked. "And why does he call you Useless, Tsuna-kun?"

Tsuna sighed. "Long story. I'll tell you guys later…" he dismissed. Even after half a year of not hearing it from the mouth of his former tutor, the moniker still stings.

"You know an assassin, Sawada?" Itona asked him.

"Yeah. Remember when I told you guys I had a home tutor before I came here? He's the one I've been talking about…" Tsuna admitted to them.

Fuwa's eyes suddenly sparkled. "You were an assassin student before any of this? Really? Are you a member of an assassin organization?"

Tsuna's face contorted into a troubled one at the overly active imagination of his otaku classmate. "No, I'm not an assassin student if that's what you're thinking…" he said. "But basically he's…"

Korosensei was the one who answered. "He's the true holder of the title World's Greatest Hitman. A man of the mafia and one of the most trusted assassins of one of the most powerful mafia families in the world. He only goes by the name Reborn, one of the Strongest Seven in the mafia." He informed, his eyes not leaving the enraged hitman in a suit and fedora. "Rumors said that he disappeared from the active scene some years ago, and many thought he retired."

Reborn let out a grunt as he listened to Korosensei's information. "Wrong. I didn't retire. I went off to teach two heirs, not like it helped one of them right now."

"Nuya! He can hear me from here?!" Korosensei said with a garble. Reborn didn't reply and just smirked at him.

"He can even read minds," Tsuna informed with a sigh. "I never seem to get away with anything when he's concerned. And now, this mess." Tsuna couldn't find the strength to protest the hitman's words. All he could process was why the hitman was there in the first place.

"We'll deal about things regarding myself later. Right now, allow me to eliminate this pseudo God of Death and wannabe World's Greatest Hitman." He said as he aimed his Leon gun at the faceless God of Death.

"You? Defeat me?" God of Death mocked. "You're just a has-been! What makes you think you could be on par with me?"

At that, Reborn smirked dangerously. Tsuna knew that it was the end for the God of Death the moment Reborn let out his sadistic side.

"Correction. You merely copied my title along with another one's, little poser." He looked at Karasuma, "You better step aside. This will get a little messy. Don't worry, I'll teach him not to mess with our students." He hinted as he tossed a tablet towards him. "Use that to call for reinforcements and some medical assistance. Someone won't survive this ordeal unscathed and without a few broken bones."

Karasuma merely nodded, understanding what he needed to do, "Thank you."

"Oh don't thank me. Thank Dame-Tsuna who ended up in your class. Now get going."

And with that, Karasuma went on to join his students and quickly went on to call for reinforcements, and maybe a medical team for both their sakes.

"Now let me teach you what you need to know, Pseudo God of Death." Reborn started as he stood with grace and poise, one hand in his pant pocket, and wore his fedora low enough to keep his eyes keenly directed at the God of Death.

The God of Death growled at being called a fake. "I am not a fake!" he said as he attacked Reborn at full speed.

"You're fate is sealed…" Tsuna muttered to himself as he watched the God of Death attack Reborn recklessly.

Reborn smirked. "Hey, don't get too excited." He said as he dodged each and every blows from the assassin as if it was nothing. It shocked the students who were a few levels above that he was even faster than Karasuma in that respect.

When the assassin got cocky, he decided to punch Reborn in the face, in which the hitman had blocked with his pistol. "Let's get started, shall we? Lesson One: Never provoke the target." He said as he sent a kick to the assassin, sending him flying to the wall but unharmed. "In order to get the target, you went after the ones whom he values the most as a teacher: his students. That was enough for you to earn a grave." He said calmly as he aimed his pistol at him and fired two shots that aimed right at the carotid artery on either side of his neck.

"Lesson Two: You lack tact. You used over twenty students just to get your target, which is a wasteful thing to do, considering that you call yourself as a skilled hitman. You have to be as elusive as possible, and yet you showed yourself to them, thus, they got a good look at your way of thinking and personality. Such a waste." Reborn said as he lunged at him and kicked him effortlessly, sending him to another side of the room.

"He's fast!" Kimura said in awe.

"And he's flawless! Look at the way he moves!" Nagisa added.

"As you would expect of the World's Greatest Hitman." Korosensei said. "He knows every tricks of the trade despite him staying in the mafia world."

"Eh? So mafia and assassinations differ?" Kataoka asked.

Korosensei nodded. "The mafia world is a world where the strongest and the smartest survive. Reborn is the strongest hitman of his generation and has connections to several powerful mafia families in the world. In fact, one of his students are now one of the most powerful mafia bosses to date. He takes pride in his skills, and he rarely shows his full potential. The world of assassination is a more silent affair, and full of duplicity. He once told me that he preferred the mafia world and found the world of assassins annoying."

Tsuna smiled at that, "That would be like Reborn to say that." He said as they continued to watch Reborn saunter to the direction of the God of Death.

"Lesson Three: the World's Greatest Hitman is the Jack of All Trades, Master of Everything. You only know the art of deception and traps. You're laughable, not even up to par with a government military man when it comes to close combat. Many would think you've gone soft, but I know the real reason. Isn't that right, faker?" Reborn taunted.

"Shut up!" the assassin growled as he attacked Reborn again, only for his attacks to be blocked and dodged without breaking a sweat.

"Lesson Four: Never frame your master and take up his name, as well as steal someone else's title. I know the real God of Death, and that's not you." Reborn said as he restrained him by holding his arms behind him. "I have worked alongside him multiple times to know that idiotic people often joined our titles together. Your master is just the God of Death. I am the World's Greatest Hitman, and nothing can change that." He then pushed him on the ground, face first.

"Lesson Five: You will always fall to the real World's Greatest Hitman. That's me."

The Pseudo God of Death turned his faceless head and glared at Reborn, "Damn you…!"

But Reborn kept him in his place the moment he let out his killing intent, making the assassin below him shiver in fright. "And Lesson Six: Never ever lay a hand on one of my students." He pulled his head to face and forced him to look above where the students and Korosensei were at. "Take a closer look at these students. One of these kids was my student, and I don't take kindly of people trying to stain my tutoring track record by killing one of my students. Lay another finger on my student, then consider your life forfeit." As he said that, Reborn used the butt of his pistol to knock the assassin out.

At that moment, the place was silent. Except for Tsuna and Korosensei, all were shocked at the display of the one-sided battle between the Pseudo God of Death and Reborn, the World's Greatest Hitman.

…

After the fight, Karasuma's reinforcements arrived and had placed the assassin in a tight stretcher. Irina, after being captured by the students and being convinced by them and Karasuma to stay, had also been looked at for her injured arm. The rest were fine as far as they were concerned. They were just grateful to be alive and well.

"I have to admit, with a face like that, who needs beauty products?" Karma joked as he looked at the fake God of Death closer who was bound in a stretcher.

The others sighed at the twisted personality of their resident bad-boy overachiever. "This is no time to admire his face, or what's left of it that is," Nagisa told him.

Tsuna looked back at Karasuma, "What do you plan on doing to him afterwards, Karasuma-sensei?"

Karasuma shook his head, "The higher ups will decide on his fate after he wakes up. I don't think that we will be seeing more of him, but there's a chance that he might come back for revenge, especially to him," he said as he pointed at Reborn who was leaning on the wall, watching them.

"How did you know Reborn?" Tsuna asked him.

"I didn't know it was actually him. He introduced himself as Renato Sinclair when I was looking for other potential assassins to terminate the octopus." He explained. "But I do know of who he really is and his connection to you." He hinted.

Tsuna sighed. "Lovro-san let you in on the secret?"

"He felt the need to. Don't worry, I won't say a word to the higher ups lest they risk facing the wrath of the Arcobaleno and your former famiglia." Karasuma assured.

"At least that's one issue dealt with…" Tsuna muttered.

Karasuma looked at the troubled eyes of the boy. "I know you don't want your classmates to know that you're a former mafia heir, and I will respect that. We will just have to come up with an excuse, provided that you tell them what they need to know without exposing your connections to the mafia world."

"Thank you, Karasuma-sensei," Tsuna thanked sincerely.

"Which reminds me…" they heard Karma speak. "Why is that hitman here anyways? It's a bit convenient that he's here to save the day, is it?" he said as he pointed at Reborn who was leaning on a wall a bit farther from where the entire class were at, gazing at the God of Death's remaining face.

Reborn tilted his fedora up and looked at the red haired teen with a smirk, "Smart kid. I was just seeing how Dame-Tsuna is holding up here. Your teacher will explain the rest, but for now…" He stated and righted himself. "Dame-Tsuna, a word?" he motioned him to meet him somewhere they would never be heard. With a sigh, Tsuna followed, knowing what was coming to him.

When the two disappeared, Karasuma sighed and pinched the bridge of his nose. "He came here under the pretense of being interviewed to be another teacher for the class." He stated.

Nagisa looked at where the two disappeared to, "Eh? He will be a new teacher?"

Karasuma shook his head. "That's not final until I talk to him officially." He then ushered the students to the medical team, "Now off you go to the medical team. I won't take any chances on your health after this ordeal,"

And like that, the matter was dismissed.

…

WHAM!

"Ouch! Reborn!" Tsuna growled and glared at his former tutor after being hit with a Leon Mallet.

"That's for hiding your skills, you useless student." Reborn lectured as he stared at him intently. "You know that you were in danger. You could have faced that faker in mere minutes."

"Yes I would have, but they had the others hostage! One wrong move and that was it for us." Tsuna argued.

"You were always so soft. But I didn't train you as an assassin, so that's pretty much acceptable. Why are Skies always so soft, especially idiotic ones?" he muttered the last part to himself, but it reached Tsuna's ears.

"I heard that!" he shouted. "And why are you here anyway?"

"Hm? Oh, I was supposed to just check up on you after Iemitsu panicked the moment he realized Maman sent you here for the rest of your middle school time. Of course before that, he was shocked that Mukuro and his gang were there living with her upon your request to look after Maman." His eyes sharpened, "Imagine my surprise when I heard from the grapevine that an international secret is here and is in the middle of being killed by twenty plus students in your age range in a prestigious school. I was only supposed to be here to check up on you and to meet the man in charge of this assassination from the Ministry of Defense since they reached out to me more than once in one of my fake names to make me teach you kids the art of assassination. It didn't follow through since that yellow thing called him in the middle of our meeting."

Tsuna shivered at the intense glare of his tutor. "Then how did you guess I was here?"

Reborn smirked. "As prestigious as the school is, you have no brains at all to enter the top four sections of your year. When I found out that the 'dead lasts' were the ones tasked to kill said international secret, I immediately knew you got roped into this." He then turned serious. "Assassination is not your forte, Tsuna. I taught you how to be a leader of the most influential mafia famiglia. Why didn't you just transfer out when the Ministry of Defense gave this to the class?"

"I know that! But the moment I found out that our class got tasked into doing this, I…"

"You were unable to refuse, since you have no backbone to refuse such a thing." Reborn guessed. "You said yourself that the mafia is a dangerous world. What the hell were you thinking, entering into a more dangerous one?" Reborn demanded, his eyes promising pain if he ever utters a single lie—which was easy for him.

Tsuna sighed as he looked at his former tutor. "I already know I had no potential as a hitman. That's your forte. But I have to at least try to help them. I've already gotten this far. Surely you won't want me to fail in my task?" he knew he was risking being hit with Leon again, but he had already sacrificed a lot on this assassination, namely his remaining sanity.

Reborn observed him for a few more seconds before tipping his fedora down. "It seems you've grown up a bit concerning duty. Maybe this is a good thing for you." He said.

"Reborn…" Tsuna muttered.

"Fine, you can stay here until you graduate, and I won't say anything to your father or the Ninth until all of this is over. But I expect you to take care of the octopus, or else," Reborn conditioned.

Tsuna nodded, eyes full of resolve, just the way Reborn preferred him. "And when this is over, I'll contact you to see how it went,"

"I just hope this is worth risking your heads for. Remember, killing a single living being who will become attached to you is different than killing a stranger for your family. Remember Parallel Byakuran."

"I know. This is an assassination to save the earth." Tsuna replied.

"I expect an e-mail update every now and then, Dame-Tsuna."

Tsuna nodded. "How long will you be here?" he asked.

"Now that I've established where you are, and had confirmed that you're okay, I leave tomorrow after I talk with your teacher."

"Tomorrow? Too soon?" Tsuna inquired.

Reborn faced him, "Colonello's getting hitched next week, so I have to be there early as the best man."

"Eh? Really? Are you sure it's not going to be cancelled again?" Tsuna asked, remembering Colonello and Lal cancelling every single wedding date as soon as they get on a big fight. He really didn't want to remember the broken buildings that went down with the cancellations…

Reborn nodded and took out an invitation. "Lal wanted me to hand you this too." He said. "Even if you won't be around, they'll send you the wedding video via courier."

Tsuna gave a fond smile, glad that his friends in the mafia world still remembers him. "I'll be sure to send them a wedding gift before next week then." He informed him. "I'll be home for Christmas holiday. Can you ask Gokudera and the others in Italy to come if they have the time?" he asked.

"I'll be sure to relay the message." He assured him. "Though I don't think Mukuro greeting them at your doorstep would be advisable."

His student chuckled at that, "Well, they are my responsibility. I can't just leave them in Kokuyo Land forever, now can I?" he said, remembering the fact that his guardians have no idea that Mukuro and his group were staying with his mother. "See you soon Reborn," Tsuna bid him.

And with that, his former home tutor was gone.

…

"So Tsunayoshi-kun is the Vongola Decimo, and one of your students. I never noticed."

Korosensei was waiting for Reborn when he left his student in the facility to join his other classmates.

Reborn took a glance at him and smirked. "Two years has passed since you were framed. I never expected you to become an artificial being." Reborn mused. "A fate worse than being turned to a baby."

"I'm pretty surprised you recognized me despite changing my form into a yellow octopus," Korosensei stated.

"With your quirks, it was easy to recognize you." Reborn reasoned.

"Nurufufufu~ I do not expect anything less from the World's Greatest Hitman," Korosensei said with his grin widening.

A small frown marred his features, "Your flattery will get you nowhere, you idiot. Framed by your student so easily, I'm pretty surprised you weren't killed off after you were captured." Reborn stated. "I warned you that it was too early for you to take in a student like that. You had no qualifications like I did when I started to train Dino."

Korosensei's head was now downcast, and appeared remorseful as his face would allow. "Well, I admit, I have no sense as a teacher, and back then, maybe I was envious that you had a student to pass on your skills. The only mistake I've made is that I never paid any close attention to my student, which now led to this mess."

"What's done is done," Reborn shrugged. "All I ask of you this time is to watch over Tsuna for me until he graduates."

"Now that, I can guarantee you," Korosensei said with a nod.

"Try not to die in a non-flashy manner, will you? Being framed as a downfall is already a great disgrace," Reborn said as he started to walk away.

Korosensei chuckled, "You have a tall order."

"I'll be keeping tabs on you via Tsuna. Don't let me down again," Reborn said and stopped to throw him a magazine. "Here. A little parting gift for the pervert that you are,"

At that moment, Korosensei's face turnd pink. "Nyu? Nya! Is this the Italian porn magazine that has that model in the interview spread?!" he asked with glee.

With a sigh, Reborn nodded. "It was hard to find that without the others finding out. I would have been branded as a pervert." He admitted. "Well, I'll be going now."

"Yeah. If things go as I predicted, this would be the last time that we would meet." Korosensei hinted.

Reborn smiled sincerely, "Then I suppose I'm glad to have seen you one last time." He said as he disappeared in the dark street.

…

"Eh? He was your life tutor?!" Kayano and the girls exclaimed as they looked at Tsuna who was smiling sheepishly. He had caught up to them in the medical area that was made outside the facility where his classmates were being checked up to find some scratches that they may have sustained in the ordeal, and Tsuna found himself being bombarded with questions concerning his hitman tutor.

"Don't you mean life coach?" Nagisa tried to correct.

"I didn't want you guys to know…" Tsuna looked away in shame. "Back then, Mom was the one who hired him to boost my self-confidence since I was bullied a lot back in the day. We didn't know at first that he was a hitman." He reasoned. It was not technically a lie per se. He was really bullied on his childhood days until Reborn came to his life which was the time that he grew a backbone. After all, he did go head to head with Hibari Kyouya, and that was saying something. "He really helped me out to get rid of the negativity in my personality," he said with a sheepish grin.

Karma snickered, "Oh, so that's why you had a sort of boss vibe in you that's stronger than Isogai,"

"What?" Tsuna wondered.

Kataoka nodded, "Yeah, you exude an aura that makes us all feel assured for something, which compliments you with Isogai very well!"

"I do?" Tsuna acted obliviously. He knew that his days as a mafia boss in-training was the cause of that, add to that, his affinity to the sky flame. It would do no good if they were exposed to the mafia world a bit too soon for his liking. If he had his way, they would remain forever oblivious to all of it.

"Yes! You were like a shadow commander in chief in the class!" Fuwa complimented. "The second set of brains hidden in the shadow of our Ikemen leader! Oh you two make a great pair!"

Tsuna held his hand up to calm Fuwa down, "Um…Fuwa-san…I don't think I really deserve that kind of view from you guys. I'm just a normal kid…"

"So what?" Karma asked, "All of the great people working in the shadows also started out as normal kids. I don't see why you have to be an exception,"

"Ahaha…I don't feel assured, coming from you, Karma-kun…" Tsuna muttered.

"But to think…" Korosensei suddenly barged in on the conversation, "There was someone else cooler than Karasuma-sensei in the world! Oh that Italian assassin vibe of his! How enlightening~!" he said, acting like a total fanboy.

"Yeah! He's handsome alright!" Kurahashi said. "With that Italian accent when speaking Japanese, his sharp features and his elegant figure~! Tsuna-kun, where did your mom manage to find him?" Kurahashi asked, her eyes sparkling, which made Tsuna cringe a bit.

"Uh…there was a flyer on our mail that day and Mom called him immediately." he answered hesitantly. "Hey, I thought you were into Karsuma-sensei. What's with that?" he said, trying to take the subject off the conversation.

"That doesn't mean I can't admire other people!" Kurahashi defended. "Karasuma-sensei will still be number one!"

Tsuna sighed. Well, at least the matter of his tutor was resolved.

…

Three days later, PE class had been jarring, to say the least.

They had been running around the mountain for three hours, which was normal for them. The only problem was…

"Sugaya and Sugino have fallen on the pit!" Ritsu announced through the smartphones of her fellow classmates.

"What? What kind of traps are in this mountain?!" Okajima asked with Itona and Muramatsu beside him, carefully checking their surroundings for traps.

The screen showed the entire class where some had been crossed out and below, were the reasons the said people were taken out, either via falling in pits, being caught in nets, chased by wild animals, and so on. In the span of ten minutes, eight have already been taken out. Okajima, who had been with Itona and Muramatsu, had been running for their lives as they tried to find the clues that were hidden all over the mountain to clear their mission in the mountain in the first place.

"Damn it! Terasaka had also been taken out by him too!" Muramatsu muttered. "Geez…I never expected the government to turn this place into a death mountain!"

A few meters away, Tsuna, along with Karma, Kayano and Isogai were treading on the trees to avoid any traps that lay in the ground. Tsuna was close to breaking down and just scream to the heavens.

"Hie! This has Reborn written all over it!" Tsuna said as he avoided another swinging log with his companions.

Isogai followed Tsuna's movements and so did the other two. "To think that your tutor could cook up something like this is amazing though," he commented.

Tsuna shook his head, "No it's not! If it's his work, there's bound to be something that could kill us!" Tsuna said, now in a panic.

...

Back at the clearing of the school, Karasuma and Korosensei watched as the students run for their lives to clear the whole-day training. Numerous screens were taken up to show each group of three as they ran past the traps that had been set up.

"The students are feeling the thrill now!" Korosensei commented.

Irina sighed and looked at Karasuma, "Are you sure the kids are safe with this kind of mountain traps?" she asked him.

Karasuma sighed as he looked at the file that the Sun Arcobaleno had given him. On the title, it read Death Mountain Training (the safe version) in neat handwriting of the hitman himself. A note was also attached to it.

This is one of the many lesson plans I made for my students. Use it well.

Apparently, upon leaving for Italy, Reborn had given Karasuma a lesson plan to use on the students.

"They will be fine." Karasuma said. "After all, if Sawada managed to evade death in these trainings, then the others will do the same." He assured her.

And thus, the Death Mountain Training continued.

END

And that's a wrap! Thanks for reading this short fic of mine! Sorry for the long wait, but I did it! I made it to the end!

Now, for some clearance in the fic:

On the matter of the guardians, I hope you guys are satisfied about where Mukuro and Chrome ended up. I purposely took them out of Tsuna's remembering on where his ex-guardians are now since they're already living with Nana for the time being.

Reborn gets the spotlight in all of this, so sorry for the ones who wanted to see Tsuna in action. With his desire to keep his former status a secret, I do think that Tsuna had to at least keep his skills known to a minimum of a few people. It's not that he doesn't trust his classmates, it was just that he didn't want them to know about the mafia world and his involvement any further.

Reborn uses a lot of fake names, though the one he uses very often is 'Renato Sinclair' in which Lovro had recommended him to Karasuma to be one of the potential teachers for 3E.

If there are some things that still confuses you, feel free to message me and I'll explain everything!

I hope you guys enjoyed this fic!

See you soon for another Many Verses of Tsuna!
