Music When Writing: Assassin's Tango – John Powell (and definitely some pudding to go with this music!)

Without further ado let's start~!

~Beyond Verde's Scientific Knowledge~

Eleventh Theorem: Classroom Daze!


"Ne, ne… who are you? What's your name? How long have you been here? Ah! You have to answer when someone asked you a question! Or else it'll seem like Haru is talking to herself! Hahi! I'll introduce myself, I'm Miura Haru! And you?"

That voice was his salvation from the dark. The complete lockdown in the Estraneo prison is one of his most vivid memories of the place, it occurs after Rokudo Mukuro and his minions killed many of the researchers.

Young Tsuna didn't speak, he doesn't want to. It felt like ages since the last time he spoke, he's not even sure if he remembers how to talk.

"Well, if you don't want to tell Haru your name… Haru will find out by herself, just you wait!"


"Oi." Reborn poke his 'no-good' student's sleeping face in irritation. It's way past the school's hours. It's almost sunset. "Oi." Still no answer. "Hurry up and wake up, Dame-Tsuna!" Reborn punched Tsuna's head to the desk. But, Tsuna unconsciously tilted his head and avoid the full-blown impact. "Owieee t-that hurts…" Our cute Tsuna rubbed his head.

Once he realized who was punching him, he instinctively lean to his chair, making it fall to the ground. Reborn smirked. "You were moaning a name, Dame-Tsuna." He said with slight irritation. "A-a name, Reborn-sensei?" The brunette stammered while standing up. He packs his school stuff, well shoving everything that was on his table, actually.

"Haru." Reborn answered, covering every drip of his irritation in his voice. Tsuna's expression changed drastically. He paled and accidentally dropped his pencil case. "So, Baka-Tsuna, the fact is, whether you like it or not, I'm your guidance counselor teacher…" Reborn pulled a chair to his place, and he sat down. "Say your problems to me." So I can blackmail you, or make Giotto envious. Reborn added, mentally.

"Fine… V-Verde-sama won't be home tonight anyways…" Tsuna sat on his chair again. Chance! Reborn smirked. Maybe he'll sneak to Verde's lab again. "So, who's this Haru?" The teacher with Fedora asked. "S-she was a friend…" He murmured. "Speak up, Dame-Tsuna, I can't hear you." Reborn uses his three fingers to flicked Tsuna's forehead.

"O-o-owwieee that hurts!"

"Repeat that again." Reborn demanded. "She was a f-friend that I…" He murmured again. Reborn kicked his shinbone and Tsuna jolted. Maybe reducing the morphine level in his body is a bad idea if Reborn is his school teacher. H-he'll discuss this with Verde-sama later.

"Repeat, Dame-Tsuna." With that, Tsuna snapped. He closes his eyes tightly and shouted. "SHE WAS A FRIEND THAT I KILLED!" A tear emerges from his right eye. He quickly rubs it away. "No need to shout." He morphed Leon into a gun while Tsuna took out a mini-handgun Glock 18. "Weapons are prohibited inside the school, Dame-Tsuna." He pointed his gun to Tsuna's head.

"I-I-I can say the same to you, Reborn-sensei…" Tsuna pointed his gun to Reborn's chest. Smart kid… Reborn thought. "On with the story, why did you kill her?" Reborn asked, still pointing his gun. "It was an order." The brunette answered shortly. Okay, this'll turn to be an interrogation of sort. Reborn thought again.

"Tell me the chronology." He ordered as he analyzes the boy's eyes. There was no hesitation, even though Reborn knows that this boy is the type to regret after shooting. Tsuna narrowed his eyes and clicked his tongue. He doesn't like this subject, and he never open this particular subject concerning Miura Haru…

"After Rokudo Mukuro and his minions destroyed the third facility house, and killing Shamal-san in the process, the other facility house lockdown all the other test subjects, preventing the disaster to happen in their branch. Including the facility house Haru and I were in. They gave us a white room with no window, except to the door. Between my room and her room, there was a very small gap between the wall and the floor, and that was the time Haru greeted me."

The young assassin inhale and exhale a certain amount of air. His firm, yet fragile grip stilled on his handgun, still pointing to Reborn's chest.

"At the first two months, I never say anything to her. Yet she constantly calls me, tells me a joke that wasn't even funny. She would tell stories about when she tripped on cable, or when she was given a straitjacket, experiences that people won't normally tell to other people. But… t-those silly stories saved me. I gradually open up to her, and I-I decided to treat her as a replacement for Shamal-san…

"And that fateful time comes. One night, Haru was called to do a midnight experiment. And she look through my door window…"

"Ah, you! Thank you for listening to Haru's chattering! So… what's your name?"

"Tsu…na."

"Hahi! Tsuna-san then! Haru will be off to do some experimenting! See you again desu~!"

"Ha-Haru!"

"And Tsuna-san… Haru loves you. S-so, Haru will fight for her love desu!"

"Then?" Reborn asked.

"I didn't feel anything like love for her. But, I consider her as what Shamal-san said, no, described as a friend. Then, my next experiment as the 27th participant came. It was to kill the 'un-obedient' ones. It was my job a-and order. If I don't follow, I will be beaten up until I fell unconscious, or better, I'll never wake up from that sleep.

"And it surprises me; Haru was the 'un-obedient' child. She was bruised and tattered already when I put my goggles on. I shook my head, not wanting to do it. But Haru smiles and…"

"Aah, Haru is so very lucky desu! From everyone that could kill Haru, Tsuna-san was the one…"

"W-wait, Haru… I-I don't want this!"

"Stab me, Tsuna-san. It's fine. If Haru dies by Tsuna-san's hands, she will be the happiest girl alive desu!"

"N-no…"

"Even though Haru still wants to cosplay, and marry you, Tsuna-san, she is happy… if she dies by your hands…"

"Haru, NO!"

"Then?" Reborn asked again.

"Then, she ran towards my blade, and pierced herself on the chest. From then on, I stopped making friends. And I will always run rampart if someone is placed in Haru's room. That is the reason I was called the successful assassin experiment, because I flawlessly killed everyone that was placed in Haru's room… and I give up, Reborn-sensei. I cannot win against you in a gunfight anyways…"

Tsuna shove his gun to his school bag. "Haru Haru Haru Haru, that's so noisy." Reborn grabbed Tsuna's wrist and pinned him on the desk, Gokudera's desk to be precise.

"Re-Reborn-sensei!"

"What? You're pissing me off; you have to pay the price." He kissed Tsuna's neck violently.

"Ungh… ahhh!" Tsuna relentlessly struggled against Reborn's grip. He uses everything. Hands- gripped by Reborn's hand. Legs- Reborn's feet are in the way. Torso- Reborn's another hand is grabbing his waist, making sure it cannot move. Heads? Reborn is kissing his neck; it is too ticklish for him to move.

"Where are my sound effects, Dame-Tsuna?" Reborn asked, smirking.

"Y-you! Arggh!" Tsuna helplessly struggled, and struggled. But, the older hitman is superior to him in almost every other aspect, including strengths. "Let go off me, Reborn!" He almost cried, but he held it in. "Not until I hear the sound effects…" Reborn kissed his lips like a savage. Like a hungry person devouring his meal.

"V-Verde… sama!" Tsuna shouted. And that turn Reborn's 'pissed off' button on.

"It's your fault for being so lovely, Dame-Tsuna!" He slapped Tsuna's pale cheek lightly, turning it red. But, he kissed it afterwards. "Let go off me!" He elbowed Reborn's chin and grab his school bag, crying, running.

"Hmph, classroom. Of all places, I chose to do it in classroom… I should've picked a better place, like the science-lab…"

Reborn mused to himself, and his laugh echoes along the classroom.


"Phone call… I need a-a phone…" Tsuna rushed to the laboratory, not giving a damn to anything else in the road. Not even calls from Gokudera and Yamamoto.

When he's finally back, he sighed. He started to cook some things he read from the Cooking for Dummies by Bianchi.

He drags his feet, and when he reached the kitchen, Sparks greeted him with a growl, and a wireless phone.

"Y-you always know about what I want, Sparks…" Tsuna petted the cunning crocodile.


"Yeah, I'm okay, Verde-sama. Don't worry. I- I'm used to be… alone" The sadness in his cute Tsuna's voice made him feel irritated.

"Are you sure, Tsunayoshi? If you cannot manage by yourself, I will return." The brunette laughed nervously from other side.

"I-I'm completely fine, Verde-sama. A-ah! Sparks! Wait until I finished-! BRUK!" Sounds like something fell to the ground. Apparently, it was Tsuna himself.

"You are making me uneasy, Tsuna. And, have you done everything I told you to?" He asked.

"I did! Wait Sparks d-don't!" This time, sounds of glass smashing the ground.

"Make sure that the lab won't be a mess when I return, yes, Tsuna?" He asked, sighing.

"S-sure, Verde-sama! Take care at your work." Verde hang up. No, he doesn't want to hang up at all. But, a jamming device interfered with his phone call. Oh for the love of Einstein, what kind of person that is sick enough to bring their own jamming device? Verde thought to himself. "No one is to speak with phones when the prince is present, ushishishi~."

"As a matter of fact, the phone call I made earlier was extremely important. And, I refuse to listen to a peculiar person like you…" Verde said, mocking a weird blond in front of him. "Ushishishi, and you must be Verde the mad scientist are you? The prince has acknowledged you, you should be happy." He grin a cheshire grin. Verde straightened his glasses.

"Hmph, now if you will excuse me, I have a fair I need to attend." He walks past through the said prince. "How is it, Bel-senpai?" A monotonous voice came from Belphegor's transmitter. "Ushishishi, I'm in Japan Science Fair right now, froggy kouhai." He answered. "Oooh, did you find the person called Verde?" He asked. "I did, now don't bother me." He activates his jamming device.

"Aaah, Senpai hangs up."

"Ara~ it's okay Fran-chan. We're going to Japan ourselves aren't we~? Aah Lussuria nee-chan can't waait~~!"

"VOOOOOI! Isn't that fucking boss done yet?"

"I'm sure… the boss is so very busy…"

At the very moment in Varia lounge, an old man enters the room. "VOOI! What are you doing here Ninth?" Squalo asked the old man. "I heard Xanxus is going to leave for Giappone after finishing his paper works. I'm thinking of helping him." The Ninth explained. "No need, old man. I've finished." Xanxus entered the room. The Ninth is one of the few people he didn't like to curse. "Boss!" Levi leaped to his side almost immediately.

"Ah, Xanxus. Do you want to use my jet? I will lend it to you." The old man pats Xanxus' shoulder. "No need, old man, I'll use Varia's private jet." He leaves the room with Levi tailing him. "He must be excited to meet Tsunayoshi-kun after so long." He wondered. "But, Ninth~ I've never saw this Tsu-chan before! How could that be~?" Lussuria asked, his butt is shaking from left to right, demanding explanation.

"There is only one occasion where Tsunayoshi-kun and Giotto-kun is brought to the Varia HQ. That was New Year eve. You, Squalo and Belphegor are celebrating outside. So, you didn't meet them." The Ninth explained. Lussuria pouted and continue to complain on his own.

Xanxus, who is still leaning to the door outside, smirked. "Tsunayoshi…"He muttered in a slight amusement.

He walked to his office, where he can still sense that little scum's scent lingers. And that was eleven years ago.

He should really talk to a psychiatrist, asking the fact that, how could he suffer this kind of disease…

Ahh, brother-complex is such a cruel thing.
