Thank you all for reviewing! I love it when I see that people enjoy my writing! So without further ado, Chapter 5 of our Vongola's horrible experience with their new Tutor~!

Disclaimer: I DONOT own D. Gray-Man or Katekyo Hitman Reborn!

All eyes were now on the curious, flying gold creature the Tutor pulled out of his sleeve. It cracked open in the middle and grinned at the people staring at it, displaying its nice set of sharp little teeth.

Tsuna gulped.

"Let the first fight between Storm and Rain begin."

Allen's POV

Yamamoto laughed as he stepped forward, his trusty katana already in his hand. Gokudera snorted as he too stepped forward.

"I finally get to beat your ass into a pulp, you damned baseball idiot!" Gokudera growled at the cheerful Rain. With a burst of crimson storm flames, Gokudera released his Vongola Gear, the cigarette-shaped lighter clenched tightly between his teeth and dynamites wound around his body like ammo.

Yamamoto was not far behind either as he too released his Vongola Gear in a burst of sky blue rain flames. The moment his fingers wrapped around the double swords, the warm, cheerful light in his eyes was replaced with one of cold determination.

Gokudera's green eyes narrowed and in an instant, five lit dynamites flew towards Yamamoto, before the swordsman could even blink, they exploded right in his face. The smoke from the bombs entirely shrouded Yamamoto from view, even the on-lookers had to cough and wave the smoke away from their teary eyes.

The smoke didn't stay for too long as Yamamoto dispersed it almost immediately with a forceful swing of his katanas. The graceful arc in which the swords moved reminded Allen strongly of a certain katana-wielding friend of his own. Though he's sure that no one back home would mind if he exchanged this one's attitude with their own.

Just thinking about that jerk made a vein pop on Allen's forehead. Shaking his head, Allen focused on the on going fight again, that BaKanda isn't worth killing his brain cells over.

While Allen had been clouding his mind with useless irrelevant things, the fight went on.

There were burnt marks all over the place and the two of them looked horrible. Their clothes were torn and they had cuts and bruises all over their bodies, Yamamoto even had a few burns.

Dynamites and various explosives flew everywhere. The bones screen shields from Gokudera's Sistema C.A.I flew around with blinding speed, blocking the well-aimed slashes from their owner's opponent. Blue flames also erupted continuously from amidst the battle. The sound of metal meeting resistance rang and echoed in the spacious training room.

The two figures jumped here and there, moments fast and swift. Occasional curses and insults would join the growing sound of weapons clashing.

Gokudera appeared to be taking the upper hand, it seems to help that his bombs were long-ranged weapons but Yamamoto's were close-ranged. He constantly kept a safe distance between them, only occasionally closing the distance to deliver a punch or a kick.

Yamamoto cleanly sliced another five dynamites flying at him into two, the contents of each half scattered across the scorched ground. He had let his guard down and had given Gokudera an advantage. But for no longer, Yamamoto took a deep breath and dashed towards Gokudera again, this time with much more speed than his previous advances.

His swords were at the ready, blue flames covered the blades. Gokudera doesn't have a chance of dodging this one.

"Shigure Soen Ryu: Clash of the Swallow!"

Tsuna's POV

Tsuna watched on nervously. It wasn't that the sight of them fighting was uncommon, hell, it's going to be weird to imagine a single second his Guardians would sit down and have a nice cup of tea to talk over their differences.

But the atmosphere was so different. It was always just fighting for the pure sake of fighting, but this time, it was like they were really fighting to kill. Their tension and the way they carry out their attacks, it felt so different. Tsuna only saw them like this when they were fighting real enemies.

It was almost as if they had pulled out every single trick they knew, poured their heart into it, and put them on the most perfect showcase.

Tsuna's eyes narrowed in concern for his fighting Guardians and friends as he watched Yamamoto blown into the wall by Gokudera's dynamites. The Rain Guardian jumped up almost immediately, his eyes still slightly unfocused from the impact with the wall. He didn't wait for himself to focus before he charged—almost blindly—at the panting Storm Guardian, swing his sword in the tenth stance of his prided sword style, Shigure Soen Ryu: Clash of the Swallow.

Gokudera's tired green eyes widened as he jumped back just in time to dodge the swordsman's attack. In his haste, he lost his balance and fell to the ground on his back, skidding a little. He didn't completely dodge the swing—however—as the front of his shirt promptly split open, streams of fresh blood joined the dried ones that already dyed the bomber's skin.

Tsuna winced, he saw this often but that doesn't mean he enjoyed seeing his Guardians get hurt—especially because of each other. This was just his Storm and Rain Guardians, the two that are considered few of the least bloodthirsty among the lot of them. Tsuna shuddered to think of Hibari and Mukuro's fights.

Out of the corner of his eyes, the young Boss-in-training peaked at the white-haired tutor at his side.

The boy was watching the fight with a far away expression. His silver eyes were fixed on the two figures but he wasn't seeing them. Then, the Tutor's expression changed so quickly into a sharp, irritated glare that could have been on par with Xanxus's, a vein popping comically on his pale forehead.

Tsuna gulped again, imagining the glare directed at him. Oh, he is never going to be late for school ever again…

Allen shook his head, as if trying to clear his thoughts. Tsuna didn't stop staring curiously as he started to mouth something to himself. The Tutor was most definitely not observing the match like he was supposed to.

Sensing Tsuna's eyes on him, Allen turned to him and gave him a warm smile. Not having been subjected to the power of one of his own smiles, Tsuna had to look away immediately in embarrassment, cheeks turning a light shade of pink. Heck, no wonder his Guardians would want to follow him, he would be willing to follow anyone with that kind of smile!

Returning his attention to the match, Tsuna found Gokudera and Yamamoto in some kind of stand still, facing each other, panting, but not making a move to attack. Their eyes never leaving their opponents, calculating and at the same time catch a much-needed break.

"Tch," Gokudera snarled, breaking the temporary truce between them. "Uri Bomb!" he yelled and threw his violent box animal-shaped bomb at Yamamoto. This was an attack that shouldn't be used so often, but as the fight progressed, they had turned out to be so evenly matched. His attacks were more or less countered by the baseball idiot, it was time to use some drastic measures.

"Shigure Soen Ryu: Splashing Rain," Yamamoto muttered, teeth clenched and swang the sword to create a whirlwind-like shield. The tranquilizing rain flame could not completely block off the blast and Yamamoto was thrown back into the wall behind him. His clothes were now almost in a burnt crisp and severe-looking burns appeared on his arms.

"Urgh…" The swordsman groaned as he tried to stand up, but all the fighting seems to be taking their toll on the teen. All the young swordsman could manage was a feeble lift of his sword. Even that caused pain to tear through his muscles. Hm, something must have torn in that arm.

Gokudera limped over to where Yamamoto was lying, his condition not any better than the other teen. With a weak flick of his wrist, an unlit dynamite landed in Yamamoto's lap.

"My win, baseball idiot." Gokudera ground out with a bit of effort before he collapsed next to Yamamoto, his light breathing came out in soft hisses through his teeth, as every breath seems to be hurting his broken rib.

"Gokudera-kun! Yamamoto!" Tsuna cried as he rushed over to his Guardians' side, Ryohei following close behind, his scalpel box weapon already out and glowing, fixing whatever he could on the battered bodies of his fellow Guardians.

"Are you guys alright?" Tsuna asked, his voice thickly layered with his concern. He helped Gokudera sit up, earning a moan from the Italian.

"Hai, Juudaime…" Gokudera muttered weakly, forcing his features to form a grin, which turned out more like a grimace. Yamamoto tried to give him a laugh but ended up coughing and choking on his own blood. That didn't help in reassuring Tsuna even one bit, mind you.

"The two of you should rest," came a voice from behind them, Tsuna could almost detect the well-hidden amusement in it. All of the heads turned to face the speaker. Allen pointed to a corner of the training room where eight white hospital beds were placed. Tsuna frowned in confusion, he didn't remember there being such a corner in this training room. But nonetheless, he helped his two injured friends to the beds.

It kind of crept him out to know that the Tutor had prepared eight beds, one for each of the eight—including Chrome—Guardians of the Sky.

As if reading his mind, Allen smiled. Not the usual polite smile that made one let down their guards around him; this one had a malicious edge to it. It made one raise even more walls than necessary around him.

Tsuna returned hesitantly to his place beside Allen after making sure that Gokudera and Yamamoto were taken care of. His hands were now thrust inside his pockets, unconsciously fisting into his gloves. Somehow, the moment the fight ended, the aura around the white-haired Tutor changed, it wasn't that much of a difference really, but it raised the hairs on Tsuna's neck and made him feel the urge to defend himself.

A hand reached over and tapped the Tutor's shoulder. Allen turned around and saw Link gave him a gesture. Allen frowned and pulled Link closer to him, Link responded by turning his ear to Allen, making a softer exchange possible.

"—Strange—no, it can't be helped—gate number eighteen—soon—" Tsuna could only catch bits of their conversation. From the way Allen and Link were talking in that hushed tone, it must have been something rather important. Link's forked brows furrowed and asked a question, to which Allen shook his head.

By then, almost all of the occupants of the room were watching the two exchange their whispered conversation.

"Allen, is something wrong?" Bianchi was the first to voice out the question on every ones' mind. With a sigh, Allen broke away from his conversation with Link, choosing to face Bianchi with a pair of suddenly very tired eyes.

"Not much of a problem, just that a little bit of…complication…has arisen. We should be expecting a few extra guests in a few moments. I would decide what to do with them when they appear." He clapped his gloved hands together again. Timcampy—who had been resting on Allen's shoulder in a scary resemblance of Hibird on Hibari's shoulder—perked up and started flying around Allen's head in dizzying circles.

"Until then, shall we continue the fight between the two teams now?" Allen smiled as the atmosphere suddenly became all tense again. Who would be the next to step onto the battlefield? Silver eyes swept across the faces, taking in the various expressions. The owners of said expressions tensed in either anticipation or fear in response to his gaze.

With a smirk, Allen announced the next pair.

"Let's put our hands together for Thunder and Sun shall we?"

Um, I think I kind of killed it with the fight scene, didn't I? Allen may have been a little darker than I had planned…

Oh woe to life!

Tsuna: Eto, Cebad-san, please do not grow mushrooms under Gokudera's bed. Especially poisonous ones.

Me: *Totally depressed* Gokudera…you don't mind right?

Gokudera: LIKE HELL I WOULDN'T MIND! MUSHROOMS ARE BAD ENOUGH; YOU DON'T HAVE TO BRING IN A FREAKING THUNDER CLOUD WITH YOU! GET OUT OF THIS STORY!

Me: *peeks out from underneath the bed and sees Gokudera drenched from the rain* I'll only go after my mushrooms produce little mushrooms…*goes back underneath the bed*

Gokudera: *PISSED* GRAWR!

Please review! (And Gokudera will into your house to escape the rain!)

Arigato!
