Chapter 2: Tsuna x Exams

...

Tsuna waited patiently as he slipped on his wool mittens imprinted 27 on it, this made Gon, who was right by him, laugh from seeing the same number on his button as well. "Tsuna, your number on the mittens and your button is the same!" Gon spoke making the brunet stare down at the mittens in embarrassment.

"Ah! You're right! Well... Twenty-seven is my name anyways... Also my mom's the one who picks out these kind of clothes for me." Tsuna smiled genuinely as his eyes shined happily from the memory he recalled of his mother. Ever since, the number twenty-seven was his favorite number because apparently it was his mother's as well. This made everyone smile as well from the brunet boy's mood, the way the boy said it could only make them recall all their dear one's with a smile on their face as well.

"Tsu-kun! Listen, do you want to know why mommy's favorite number is twenty-seven? It's because thats my most special boy's name!"

Tsuna couldnt help try to remember the face of his mother, he knew she was stunningly beautiful but her face just couldn't be pictured in his mind. Afterall, its been far too long but her loving sound of her voice and her warmth was clear as day. Something he could never forget.

Soon a loud ringing was heard that sounded oddly enough, like an alarm snapped Tsuna out of his thoughts. Mostly everyone looked around to find the said ringing while other's only stared at the wall, but the startled brunet was turning his gaze left and right like many others. Within moments, the wall opened up to reveal the tunnel even deeper than before with a single man standing there, holding an alarm with a mouth. Clearly it was repetitively ringing making a few give curious eyes as to why. The male wearing a purple suit and white short combed down hair soon turned off the alarm with a push of a button on top of it. Tsuna could only curiously stare at the mouth-less man, he was a child raised on a small island, seeing a male without a mouth only intrigued him ever more so.

"I apologize for the wait, the entry period for the hunter applicants has ended. The hunter exam will now begin!" The mouthless man spoke, as everyone only became more tense as the air grew thicker. The brunet could only narrow his eyes as well too, he was physically ready to do anything to earn his license. "A final caution, if you are short on luck or ability, you could very well end up seriously injured or even dead. But, to those who accept the risks, please follow me. Otherwise, please exit via, the elevator behind you." The male continued as everyone stood their ground, prepared.

"Very well, all 404 applicants will participate in the phase one." He soon turned, raising his foot and his arm in a somewhat perfect ninety degree angle with his body before marching down the tunnel. Everyone soon followed rather patiently in slow paced walks, making Tsuna only turn his gaze up and around from how claustrophobic he was feeling with taller men literally side by side to him.

"Man, no one turned around and left. I was hoping a few might withdraw." Leorio spoke only making Tsuna turn his caramel eyes to the side to glance up at him. Without a word of response the male soon dropped the conversation as his eyes focused on the front. Within a few minutes later, the pace began to increase as everyone went from a causal walk to jogging. Everyone's faces grew surprised as it did.

"What's going on?" Leorio spoke as Gon was the quickest to answer his question.

"The people in front started running." He spoke out, pacing his breathes, getting ready just in case they continued to run.

"He's picked up the pace." Kurapika last spoke with a somewhat concerned gaze as he eyes were focused on the front.

"I neglected to introduce myself, I am Satotz, the phase one examiner. I shall lead you to the exam's Second phase." Satotz spoke as he continued to march in an odd way, but only faster.

"Second? What about phase one?" A voice spoke up, questioning the examiner for everyone else in the dark tunnel.

"It has already commenced." Satotz answered seriously as everyone became startled.

"What, it has already begun? This is part of the test?" Many voices shouted out making Tsuna only ponder about this test.

"You must follow me to phase two, this is this exam's first phase." The examiner spoke once more as he turned his head, answering the participants questions again.

"Follow you? That's it?" The first person who spoke out for everyone only questioned, once again questioned.

"Yes. I cannot tell you where or when you must arrive. You just need to follow me." Satotz spoke for the last time as he turned his eyes to the front.

"I see how it is." Kurapika only said briefly, thinking about the test as Tsuna glanced over at him.

"This test is weird." Gon, who wasn't wearing his usual smile, only continued frown as he spoke after Kurapika.

"I expect it's an endurance test. Fine by me, I'll be right behind you!" Leorio confidently shouted in excitement, breaking the serious tension around them. Both Gon and Kurapika only gave a small smile in their companions courage.

Tsuna let out a small hum in reply, this test was rather common for him to do. He was just relieved it was nothing like killing for sport to become a Hunter. Quickly enough, the brunet boy reached over his ring around his neck and gave it a tight squeeze. 'Just wait for me mom, I'll be with you soon.' He thought in determination as he continued his jog with the group as a smile soon crawled on his face.

...

...

Tsuna continued pacing his breaths calmly, trying to keep his composer. After all, Fon, another tutor, taught him that the key to great endurance is all in breathing controls. If you can control your breathing, you can control your body to an its maximum output. The brunet gave a small smile, he was somewhat thankful of those relaxed teachings compared to the other six tutors excluding one. Lal and Colonello was his brute force tutors but both taught two different things.

Lal taught how to keep track of a target in combat, along with switching styles to keep your moves unpredictable. Colonello taught muscle building and reflexes to keep his intuition sharp, so Tsuna could avoid any fatal injuries. Them both combined was extremely torturous, almost on par with Reborn who planned every training course. Luckily for him, he had Fon and Luce as his tutor.

Fon was extremely gentle when it comes to teaching and also equally patient. He trained body and mind control to keep anger at bay and different types of martial arts along with acupuncture lessons. By far, him and Luce was the best tutors he could possible ask for. Luce, who was equally nice, taught him body language to help read other's intent along with kindness. Kindness was a key benefit to be a boss but only to an extent, no one will follow a boss who is too coldhearted or kind. It was something Tsuna also agreed on.

The other four tutors sent chills down his spine as well as the first two, Lal and Colonello.

Skull being next showed him how to receive pain and flexibility. The tormenting pain he endured only sent chills down his spine, it was inhumanly impossible for anyone to get use to such torturous methods he continued to go through. The brunet almost lost his composer from the thought of those sleepless nights of bones breaking and his bloody screams as cold sharp metal scraped against his body. Although it was horrid, the boy could only be grateful for them helping him. Flexibility was equally torturous, he had to stretch and move some of his bones in certain directions.

Verde wasn't extremely bad, just boring. He had to learn things on par with a scholar in college. History, mathematics, trade stocks, gambling, scientific things, Mafia families, every single important event in the world, writing, and business composer. Everything was extremely boring and overwhelming for a kid who wasn't THAT smart. Everytime he didn't listen, training was increased byseven folds from everyone else. That threat alone made obediently listen wholeheartedly.

Viper, or Mammon was the worst. This made everything harder for him. Killing, Torturing, and getting information from dead bodies. The brunet's stomach turned from the thought as Gon glanced over his pale friend.

"Tsuna! What's wrong?" The worried green haired boy spoke as the brunet only smiled reassuringly. Thankfully Gon snapped him out of his thoughts before he began to stop and throw up.

"I'm ok Gon. I was just thinking about something." Tsuna gave a thankful smile to the other as he only grinned out as happily and focused on maintaining his run.

The brunet gave a sigh, he didn't want to think about Mammon once again. His only thought was on Reborn, the genius hitman who taught him balance. He prevented Tsuna from being memory overloaded from all the things he learnt, this only made the brunet boy's eyes shined with determination once more. Yes, all those trainings were tough and he endured so much over the course of practically years that he hardly remembered his own mother's face. But they were worth it all, now he was stronger than an average person and could easily fight anyone with his little underestimated body. He was more than ready to take on anyone to make the Vongola better.

...

"Hey! Wait a minute kid!" Leorio's voice rang through Tsuna's ears, making the said brunet lay his eyes on the male in front of him as Gon did as well, curiously.

They both turned to the source of the reason why their friend was shouting only to be surpised. In front was a white haired kid around the same age, riding a skateboard. His attire was a dark blue long sleeved shirt underneath a light, almost white purple short sleeve v-neck shirt with faded blue shorts. His blue eyes peered up curiously to see an angry older man staring at him, the boy only let out a hum in reply not even faltering from the angered look.

"You should show the Hunter's exam some respect!" Leorio shouted once more, only confusing Tsuna, the boy Leorio was talking to, and Gon all at the same time. This earned the white haired kid's attention fully, making him actually turn his head to the older male.

"What do you mean?" He spoke curiously.

"Why are you using that skateboard!? That's cheating!" Leorio shouted as he pointed to the skateboard as the boy glanced down.

"Why?" He spoke as up turned his gaze back up to the man.

"Huh? Why... This is an endurance test!" Leorio almost tripped from the kid's innocent answer before shouting even more upset.

"No, it isn't!" Gon spoke out, breaking their conversation making the said two turn both their heads to Gon from the new voice cutting in.

"Huh? Gon, what are you saying?" Leorio asked his friend, peeved that Gonwouldn't take his side instead.

"The examiner only told us to follow him." Gon who was oblivious to the hurt and betrayed gaze Leorio wore. This made Tsuna let out a small giggle as Leorio glared accusingly at them both now.

"Whose side are you two on, huh!?" He shouted out, throwing his fist in the air as Tsuna only let out more burst of giggles.

"Ah sorry Leorio, it's just silly to see you fight with a little kid!" Tsuna couldnt help but bursted more laughs after attempting to cover his lips with his hands.

"What did you say!?" Leorio shouted even louder as Tsuna couldn't help but continue to laugh, not even noticing the boy talking to Gon.

"And you?" A voice spoke to Tsuna, making him slow down his giggles before glancing over. The said boy who was just arguing with Leorio was peering up with those bright and curious sapphire eyes.

"Ah! Um!" Tsuna fumbled out slightly from the attention only making Gon beside him let out a small snort in laughter.

"This is Tsuna! He's the same age as well!" Gon spoke out as the white haired boy only continued to run with his skateboard to the side. This made Tsuna curiously stared at the board, 'When did he started running?' Was all that processed in the brunet boy's mind.

"W-wait, I didn't catch your name." Tsuna glanced up in realization as the white haired boy only gave small recognition.

"Killua." was the only thing the boy named Killua said.

...

...

Tsuna let his mind wonder off once more, he wasn't exactly tired from the running but he certainly wasn't thinking straight. All he could think about was that negativity of him losing, that what if he fails this exam. What if his mother is already dead. The thought rose anger inside of him, desperation, and the adrenaline to run faster. Tsuna inhaled slowly and exhaled the same to calm his heart, next thing he knew was he was running in a completely different place. Gon and Killua no where to be found.

'Did I accidently run up too far?' Tsuna pondered as he observed his surroundings. He was clearly in the front, where Satotz was in the line of sight. From both sides was other men and some women, keeping up at examiner's own pace. But none of that matter as the brunet boy only was curious in one person, Hisoka. The jester glanced over with a small smile on his face, noticing the boy staring up at him. Tsuna could only slow down his pace, his glaring eye's never leaving the red head as within moments the only thing he could see was a distant figure.

"Ah Tsuna!" Gon shouted out, catching up to the brunet with a small pout on his face. Tsuna only turned his head over, all traces of precaution leaving him. He gave a small apologetic smile making Gon only lightly flush in embarrassment.

"Sorry, I didn't know what came over me." Tsuna spoke as his expression was almost like a kicked puppy. This made Gon brighten up, forgetting why he was pouting in the first place.

"Well it's fine! Hehehe." The green haired boy only grinned happily making Tsuna smile ever more so. Killua only stared at the two in front of him, 'What a couple of idiots.' Was all he thought, as he couldn't help but tear his eye's from the scene with a small blush on his face as well
