"You add X to the equation and substitute the coordinates into it to find the unknown before applying the known numerical for each unknown to solve for the gradient. After which you apply all these to…"

Tsuna deadpanned at the explanation. All he could understand from his genius friend's rambling were X and Y. Math never made any sense and Tsuna did not see the point in having to study something so irrelevant to his life. He did not require such advance Math to order a burger at a fast food restaurant. Remembering the value of pi did not deter the bullies from stealing his lunch money. Finding X and Y never helped Tsuna to deny his position as Vongola Decimo. Reborn often taught him Math that were unrelated to exams or life which was worse. He could not understand how Yamamoto could do better in a subject they both could not comprehend. Tsuna could not understand how Gokudera can become so enthusiastic with the irrelevant subject either. All he wanted was to graduate from school quickly so he would never have to face the numbers and unknowns again.

His dreams were dashed when Reborn disguised as Boreen sensei popped from nowhere again. Tsuna prepared himself mentally for the torture to come.

"Tsuna, Yamamoto and Gokudera listen up. The finals are coming and you will all need to do well enough to enter the same high school. As a family, you ought to help one another. I understand that Gokudera is smart enough with your academics but I have engaged a tutor that will help you develop people skill. After all, it is the duty of the right hand man to build and maintain alliances on behalf of the boss. Yamamoto may be outstanding in the athletic field but is lacking in academic. I arranged for a special tutor to help you out as well. After all the school we are aiming to go to is Namimori High. As for Dame Tsuna, you require the most help. Your academic standard is the first from the bottom and your athletic prowess fared no better. You should work harder as Vongola Decimo."

Tsuna groaned. He did not want any more of Reborn's antics. He had enough on his plate right now and Reborn's help would only make things worse.

The next day Reborn had the trio gather on the rooftop. Reborn smirked in triumph. Tsuna glanced over the roof every now and then. Reborn seemed to be waiting for someone.

When the door to the rooftop burst open, Tsuna brightened at the sight of Dino. Then a chill ran up his spine as Mukuro blew a kiss into his ear. Tsuna yelped while Yamamoto laughed airily. Gokudera hissed while Dino did his best to restrain the bomber. Unfortunately, without the trusty right hand man around, Dino's clumsiness led to a series of awkward happenings.

Once Reborn fired a warning shot in the air, everything went back to normal. Satisfied with the attention, Reborn began to give instructions. "Dino, you will be coaching Gokudera how to be better at socializing as a right hand man," at that Gokudera's face fell. He never expected Dino to be his tutor. That blonde man was the clumsiest person he knew who screwed up with a water absorbing turtle. Displeased he made intent to voice it out but Reborn's firm stare cut him off. Silently relenting, Gokudera agreed and accepted much to Tsuna's relief.

Then Mukuro chuckled weirdly. "Reborn, since you freed me from the Vindicere I am assuming you made a pact with those freaks. Whatever might that be?"

The twinkle in his eyes was not missed. Reborn smirked at that and played along. "Well, of course it is to coach Dame Tsuna. His grades are pathetic and he is weaker than a Chihuahua dog. What can I say? There would be no better teacher than you. After all, Dame Tsuna has rejected my loving education methods."

Mukuro laughed. He felt the murderous intent from behind the water tanks and caught how Reborn's lips curled into a smirk. "Oh well, I guess if you say so arcobaleno then I am obliged to obey."

Tsuna let out his trademark yelp of fear. To which the sensitive skylark's ear twitched. Hands readied with the twin metal tonfas and he poised for the kill. Mukuro's hand reached out to cup Tsuna's cheek tenderly and the act made he prefect see red.

A tonfa embedded itself onto the ground where Mukuro was last standing. Tsuna's shaky legs gave way and his butt made contact with the ground painfully. If he had not been numbed with fear, tears would have welled up at the corners of his eyes, something Hibari would secretly relish.

"Oh, Hibari! How nice to see you. How can I help you?" Reborn feigned ignorance of the matter at hand.

Tsuna thought his heart might stop the moment Hibari's icy hands grabbed his arm painfully and lifted him off the floor. "I will be responsible for this student. Allow me to tutor him."

Reborn smirked inwardly. Exaggerating a sigh, Reborn agreed with reluctance in his voice. "I guess I have no choice then. I'll be leaving Tsuna to you."

Mukuro chuckled and Hibari glared at the blue haired man. Sparks crackled when they made eye contact. "Touch him and you won't see tomorrow again."

Mukuro merely waved and chuckled. "How protective…" he mused. Reborn allowed a small smile to play on his lips as he announced the 'change' in plan. Yamamoto readily agreed to have Mukuro tutor him. After all, Mukuro lived enough lives to know basic school subjects.

Back to Tsuna who was dragged to the reception room by Hibari, he sat on the couch nervously. Occasionally peering up from his brown bangs, he too peeks at Hibari as the older boy worked on a stack of paper.

Hibari felt annoyed at first when the pineapple haired illusionist touched what was his. He hated when the baby manipulated him. It was just not the right time to be doing this. The omnivore had to focus on his studies and not be bothered by Hibari's feelings forced unto him. He will get to that later. Expediting things were the baby's doing and Hibari was pissed that he fell straight for the trap.

Now that he was immersed in doing paper work, he felt slightly calmer. The composure came back and he found pleasure in watching the omnivore's antics. His shy glances and timid peeks as well as quivering lower lips as if he wanted to ask something made his carnivorous heart race. He wanted to bully the boy a little more so he pretended not to notice.

It was until Tsuna could not tolerate the silence between them that he broke it with his shaky voice. "Um… Hibari-san? Why did you bring me here?"

Hibari paused and placed his pen down. "Is it still not obvious yet herbivore?"

Tsuna looked down dejectedly and squeaked a no. Hibari smirked. "You had the nerve to let the pineapple touch you. Did you want him to possess you so badly?"

Tsuna gasped in horror at the mean things Hibari said. "Hibari-san! I would never… how can you say that? Besides, it was Reborn's idea."

Hibari donned the devil's mask and played mean. "It wouldn't have been his idea if you had been good at sports and studying."

Tsuna felt a sense of betrayal from the harsh words Hibari spoke. None of them were false and yet it hurt badly. Tsuna was so confused why he would be so affected when he had been used to such things. "Perhaps it's because it is Hibari-san?"

"I'm sorry for being No-good. I tried but nothing worked out. Reborn is closer to trying to kill me than help me. I thought… I thought if it were someone else more reliable I might be better. Gokudera-kun tried but I'm simply not as smart as him to understand anything. Yamamoto tried but I'm not gifted with instincts. Mukuro might have been able to help me because he has a lot of experience…"

Hibari slammed the desk. "And you think those experiences would be used for decent things."

Tsuna gulped, unsure of what to make out. "Decent…?"

Hibari walked over to Tsuna with the air of a predator approaching its cornered prey. Tsuna felt afraid. He had nowhere to run. Closing his eyes, Tsuna prayed for it to be less painful. Only, the pain never came.

In fact, only a warm and soft pair of lips met his. Tsuna gasped in shock. Hibari bit down on that tempting lip that quivered so innocently. "That, herbivore, was the kind of things Mukuro would have done to you with the experiences he had. Also, he would not stop at that. It could be worse. Be thankful I bailed you out from that fate."

Tsuna blushed, not knowing what to make of those words.

Hibari turned around and threw Tsuna his bag. "Go home herbivore. Tomorrow after school, come here. We will commence your lessons to becoming an omnivore."

Tsuna smiled. Suddenly having Hibari as a teacher did not seem like a bad idea.
