Chapter 1: Terrifying Impression

"Ciaossu. I'm Reborn and I am your Home Tutor."

Brown eyes stared at Reborn in surprise and no small amount of incredulous and disgust. Probably at the thought he was going to be taught by a mere "baby". Well, Reborn will have the utmost pleasure to beat that out of this child. Appearance can be deceiving. One of Important Lessons in Life is You Should Not Underestimate Anyone.

Tsuna stared, before sighed and turned to his mother. "Mom, I appreciate you tried to make joke, but this is too early for this and it's not funny." He chided her before finishing his breakfast.

Reborn raised an eyebrow at this.

He was send here to train one Sawada Tsunayoshi into Mafia Boss, out of few favor he owed to Vongola. The files he got stated that Sawada Tsunayoshi is clumsy, academically-pitiful person whose self-confidence is lower than newborn puppy. This Sawada "Tsuna" Tsunayoshi he was currently observed, is a normal teen who walk with grace and carefulness, and he certainly have some guts.

Not to mention, glasses.

In the files Reborn had, there's no mention of Tsunayoshi ever had problem with eyesight, leave alone one that leave him in need of glasses.

Maybe that was recent addition. One doesn't need glasses until their eyesight had deteriorated that much to the point having problem seeing things. Maybe Nana had seen her son squinting one too many times and bring him to optometrist yesterday. Okay, Reborn is going to let this one slip through.

Still...

"Would you please not hijacking a ride on my shoulder, mister?" Tsuna ask politely. "You almost made my glasses slip off. And it's impolite seeing I never gave you permission to do so."

Reborn hummed. "Well, as your home tutor, it's my duty to see your performance in the school." Because while the glasses can be forgiven, the personality trait is NOT. Something so simple like hobby or habit can be valuable information. And if they can't get it right, what else was wrong?

Tsuna frowned. "I don't recall agreeing to that one."

"No. But your mother is."

Tsuna's eyes twitches and he looks constipated. It was kinda funny, seeing that from this angle.

"I doubt my teachers will allow this. They... ah, tends to have very narrow world-view of what acceptable and what not. My classmates too can be, well, rough. And the prefect was very strict regarding rules regulation." Tsuna tried to dissuade him from following to school. Cute. "Plus I doubt there's anything exciting in the school. You will be bored to sleep."

"After all, anything that can be called exciting and adrenaline-pumping never happens in school ground or during school hours."

"What was that about?"

If Reborn don't literally sat on Tsuna's shoulder he might've missed that. And they're in English. So the brunette implying that there's something exciting happening, but they were never took place on his school or during the school hours?

Tsuna was startled and almost tripped over his own feet. "W-wha?" He gasped. "What do you mean?" He ask, panicked.

"You said anything that fall into category Exciting never took place in your school, or at least during school hours. So something had happened but that's happen somewhere else, right?" Pressed Reborn.

"A-ah... umm... w-well, The Festivals doesn't happens during School Hours, does they? Especially the ones involving fireworks? O-oh, and snowball fight. That was exciting too. And summer trip. That was fun one."

"Summer trip to Britain, you mean?" Tsuna's face blanched. "You speak English for a moment, earlier. And not just any English, but one with UK Grammar and British accent." There's difference between American Accent and British Accent. And spelling. One of such is Gray versus Grey.

"So?"

"W-well! I have pen pals from Norwich and sometimes chatted with them so... I kinda pick their accent?"

Hmm... this merits some investigation. Perhaps potential Guardian Candidate? He need to know who they are and where exactly they lived before arranging something.

"So you do have friends."

Tsuna bristles like a cat. "Of course I have!" He snapped. Oh my, looks like Reborn had stepped on a landmine. "What makes you think I don't have any?"

"Hmm... I don't know?" Reborn smirked. "Maybe because you looks like a nerd?" He snatched the glass and jumped off. Hide the glass inside his specially-tailored suit.

Tsuna frozen stiff, before he closed his eyes.

"Give back my glasses."

"No."

"Reborn, give back my glasses."

Reborn could felt Leon tensed up and hide under his shirt.

"Why should I?"

Something inside Reborn was SCREAMING at him that something was WRONG. Reborn frowned. There's something wrong. Tsuna's expression without the glasses was too cold to be natural.

"Sun Arcobaleno Reborn, You will give my glasses back in this instant."

Reborn shocked. Tsuna knew... He fucking knew! HOW?!

"How did you know that?" He hissed, his gun was out and this one has real bullet. "You supposed to not knowing of that." Nono told him that Tsunayoshi was a civilian, and civilian can't know that accursed title of his! So, how? Underworld contact? Is that his friend from Norwich?

"...so you are refusing to return my glasses." Tsuna spoke, gently yet so cold that hair on Reborn's neck were standing on their end. "Very well." The brunette took out a ballpoint from his pocket pants and turned around...

...and Reborn's gun broke off into small parts.

Reborn stunned. What... what did he... Tsuna just moved really fast and the ballpoint pen touch the gun briefly, and then it broke. A Mafia-Grade Gun he specifically custom-ordered, one that can withstand heat and pressure, as he doesn't know when he will use his Ace Trick, destroyed just because tiny, weak tap from a cheap pen.

"!"

He almost cried in surprise when the pen moved to small crink on his sleeve and next thing, his suit ruined up. Like something invisible, perhaps an invisible sword had torn them up. The glasses fell off, ruined as well.

Tsuna's eyes narrowed.

Time seemed to stop.

Reborn resist urge to gulped. Why does he feels like shinigami was looming before him...?

"You, are dead men walking, Reborn." Hissed Tsuna. The ballpoint in his hand glinting under the sunlight like a murder weapon. "Dead. Men." With that, he turned hot on his heels, stomping his way to the school with murderous and apathetic aura that reminds Reborn of himself during his prime two decades ago, when he was in such foul mood and ready to murder someone just because they were in his vicinity.

...he belatedly realized he was trembling.

"What... was that?"

That eyes... that cold stare and aura... Tsuna was fully prepared to kill him. And if the weird episode regarding his gun was any indication, he can kill Reborn with little to no effort, and nothing Reborn can do to stop him.

"Sawada Tsunayoshi... what on earth are you?"

For the first time in long time, Reborn felt fear.

~X~

Takeshi cursed up a blue streak. He was late! His stupid alarm clock failed to ring on time and his dad was gone out of town. He was late! Oh, Hibari-senpai will kill him. The question is whether with glare or with that dreadful tonfa of his! W-well... if he be sneak about it and went through window... maybe he will survive? Today is Nezu's lecture so he can wait till the right opportunity till the man gloating, so he can snuck in?

As he reach the Namimori Middle's gate, he saw figure with black hair wearing black jacket with red armband and holding a pair of weapon marching at him.

Shiiiiiiiiiitttt!

Hibari saw him. Oh he is so dead!

"Omnivore—"

"Waaaa! Hibari-senpai please don't kill me!"

"—get into your class now."

"I swear I will not get late again! I—eh?" Takeshi realized Hibari attacked him. Forget that, Hibari didn't even glare at him. He instead looked at certain direction with... was that nervousness?

"Senpai?"

"Hurry up and put Shinigami back to sleep, Omnivore."

Put Shinigami back to sleep? But the only one with that nickname is...

Takeshi's eyes widened. "Don't tell me?!" He screamed, before dashing off to his class. Using Reinforcement to reach his class within five seconds flat, he paused before the classroom door and deactivate his circuit, and gingerly open the door.

The class was deathly silent and the noise the door made sounds like someone sharpened a execution sword against Wheatstone. The whole class was in silent, safe for few weak, nearly inaudible whispers from bolder students. Even Nezu who usually have no brakes or filter on what he said was staring nervously at certain someone next to window.

The sheer of Killing Intent alone!

Takeshi swore he will have words on whoever cause this to happens. Probably bringing Shigure Kintoki with him as well.

"A-ahaha... s-sorry I was late." He announced himself weakly, gaining stares from the whole class.

Some was incredulous he dare to speak, some was admiring his braveness... or perhaps idioticy, some was staring as if he was going to die soon (which was likely would happens should he didn't brought it with him), and one was looking at him as if he was a frog on dissection table.

Takeshi walk to Tsuna's desk and take a spare Special Glasses from his own bag. With one smooth movement, he slide them to Tsuna's face.

"You should be more careful, you know." He murmured.

Like a miracle, the killing intent disappeared. What before was a cold face carved straight from Ice block, now there's a humane expression on it. Tsuna smiled sheepishly and scratched his head. Many were releasing breath they didn't realize they were holding this entire time.

"Hehe..." Tsuna chuckled weakly. "But it wasn't my fault... well... perhaps I do have a hand in it..." He put a small round mirror from under his desk and put it in certain angle.

Takeshi's eyes narrowed when he saw a figure wearing black.

"...I see..."

Looks like he know the whodunnit. All that's left is Whydunnit.

Stupid Mafia and their Stupid Games.
