These stories will most likely be one-shots of alternate universes or ten years later. Pretty much whatever comes to mind.

Title: Harmony factor is terrifying.

Summary: Tsuna snaps. His friends reflect on how it is completely unfair how over powered he is.

As per usual, the Varia and Guardians weren't getting along. Was it because of the clashing personalities? The fact that Xanxus was still pissed at Tsuna for gaining the title (even though the scarred man doesn't want it anymore, too troublesome) and holds a grudge, because he's Xanxus. Maybe it was Tsuna's fault for not putting his foot down and banning fights anywhere but the specified sparring areas.

However you look at it, it seemed only natural that the two groups would clash both with each other and internally. However, that fact didn't matter to poor Tsuna, who had to pay for all the fees accumulated from the destruction of the mansion and all of the really, really pricey artefacts within.

Then there's Xanxus, who goes and foists his paperwork off onto Tsuna, as well as try to kill him regularly.

Dino, who causes just as much damage whether or not he's fighting or just clumsy.

Enma is fine but his guardians are only a step down from Tsuna's in regards to property damage.

Byakuran is just Byakuran and, weirdly enough, a master at hide and seek. They lost him for five days. In their own base! Yuni was no help.

Don't even get Tsuna started on his own guardians, who cause most of the problems. Enemy famiglia at our doorstep? Don't have enough time - Lambo tripped and Kyoya got hit with the bazooka - we're all going to die anyway, might as well just let them in and escape while the biggest threat is distracted.

Well, Tsuna was done. Just done. No more. He tried Zero Point Breakthrough: Guardian Edition (one he came up with himself that made their muscles seize up) but then he felt bad and freed them, only for them to force him to do it again later that day.

Done. So completely done.

"Trash! Where are you?" Tsuna sighed into the pillow his face was mashed into and shifted around on his office couch. His annoyingly large belt buckle was digging into his stomach and the shirt was too tight. Reborn had been playing in his wardrobe again, shifting small things around and making him paranoid.

Just finished.

"Dame-Tsuna." Speak of the devil... "Get up, you have a meeting scheduled with Xanxus and then you need to find where your Mist hid a body."

Just. So...

A hand tugged on his hair lightly. "And not your creepy Mist either, it was Chrome." Tsuna lurched up to his knees and grabbed Reborn's tie, pulling him close and practicing something he's worked very, very hard on.

He was done.

When the Vongola guardians and Varia stumble in through the doorway to Tsuna's office, they grind to a halt almost immediately. The first thing they take in is Tsuna's back to them. His shirt was unbuttoned and slipping down his back, only his arms that were still inside held it up.

The next thing is that he's straddling Xanxus who was pressed completely against the back of the couch, his hands on Tsuna's waist. At this point in time, weapons that had drooped in shock were raised and aimed.

Both bosses haven't moved, nor reacted at all to the intrusion. Also, it didn't seem like Tsuna to not immediately leap away when discovered doing - ahem - acts so they charge forward more confused than homicidal.

Hayato is the first to circle around to see their faces but the rest soon follow. Centimetres apart, they were just starring at each other. Then Squalo caught sight of Tsuna's eyes. They pulsed orange and brown at changing intervals, spreading from the constricted pupil all the way to the rim of his sclera. Xanxus was completely still and, strangely enough, his pupils were spread wide as if to catch every movement.

Levi puffs up and open his mouth to scream at Tsuna but is interrupted with a punch by Lussuria who was taking pictures quietly at the back.

Tsuna inhales deeply and speaks with a calm voice.

"I will not force Tsuna to pay for bills caused by my subordinates again." Xanxus shifts a hand, tightening it against Tsuna, but slumps again in the next second. Incredibly enough, Xanxus echoes him back in a monotone voice.

"I will not throw glasses or bottles of alcohol at Tsuna." This time the Varia boss slides a hand to his X-gun in a hip holster. Tsuna's eyes pulse faster, slow and then faster again. Xanxus relaxes, responding with the same words.

A few more minutes and Tsuna's head snaps back as if there was something that held him before. Xanxus' head falls and jerk back up like he's trying not to fall asleep. They both gasp.

"So," Tsuna began, "what was that about bills, Boss of the Independent assassination squad?" Even as he collapses to the side, still half flung over Xanxus' legs.

"You needed to p- pa- shit. I got it." Xanxus snarls and flops onto Tsuna, causing him to squeak and the breath to rush out of his lungs when they get squished. "Fucking harmony factor and your fucking hypnotism." Xanxus grumbles into Tsuna's bare chest, making him squirm, ticklish.

"What just happened?" Takeshi asks.

Tsuna tilts his head back over the arm of the couch, and looking upside down at them, his eyes pulse orange.

"Leave."

They snap out of it only when they cross the threshold. They then proceed to try and scrape their chins off the floor. What kind of unfair bullshit was this? Tsuna could freeze them, paralyze them and now this. If Tsuna was anymore evil he would be ruling the world already.

"Don't worry." Reborn speaks up, sitting on the floor outside with a belt tight around his neck. "He used it too much so your command faded quickly. Just don't look into his eyes, or wait until he gets too tired to continue."

Lots of eye movement and small nudges later, Belphegor got the unfortunate honour of asking the world's greatest hitman: "What are you doing out here?"

Reborn scowls and caresses a whacked out looking Leon. "I was first test subject." His eyes find all of theirs at the same time in a way only Reborn can manage. "I'm feeling quite bored, sitting here. You'll play with me, won't you?"

A/N: I can't believe that flame powers weren't elaborated on in the manga. I mean seriously, I was half expecting Hibari to just whack a wall and a huge concrete spike would jut out and stab his opponent. I admit that this power of Tsuna's may be far fetched but seriously, if I had propagation, I would fuck shit up. Multiply an opponent's heart tissue or something so it explodes out of their chest. Can we get some creativity here? I was most disappointed with mist flames, because pillars of lava were cool and all but a couple dozen spiders digging their way into an opponents brain would have been far more subtle and worked far better.
