Reborn looked at the locked door with some confusion.

"What in the hell are they doing in there?" he asked Haruto. The room was insanely soundproofed, and he was baffled as to why Tsuna didn't argue when Byakuran basically nabbed him and Shōichi, with Spanner cheerfully following behind.

"Stress release. That and it's to keep Byakuran from driving us up the wall with his schemes for world domination," said Haruto.

"Stress release?"

"They're teenagers. There's no adult supervision and the room is sound proofed. What the hell do you think they're doing in there, playing checkers?" said Haruto with a raised eyebrow.

Reborn choked.

He remembered how Tsuna was before he was reincarnated, and he was more interested in science and alchemy (and getting his body back) than in acting like a normal teenager. And his brother had been stuck in a suit of armor for that entire time, so he never had the hormonal impulses.

"Are you telling me they're..."

"Going at it like bunnies? Yes. Again, it's mostly to keep Byakuran sane because he has a vexing habit of following through on his world domination schemes he makes out of boredom if we don't distract him with something he likes more. Which in this case is Shōichi, but he doesn't mind sharing with others."

Haruto suddenly shuddered.

"We learned the hard way not to let his boredom get so bad that he actually follows through with his plans."

Reborn smirked, still reeling a little bit learning Fullmetal did acknowledge his hormones in this life.

"Now I have to know."

"Let's just say Verde was sleep deprived when he went along with it, and it involved marshmallow Peeps. A lot of marshmallow Peeps."

"Details!"

Verde heard what they were saying and scowled.

"I thought we agreed never to speak of the incident again."

Reborn's grin was evil.

"I have to hear this now. What could possibly have Verde react like that?"

Fon's usual smile cracked a bit.

"We agreed never to speak of that again."

"He's not going to give up until he hears what happened, is he?" asked Haruto.

"It's Reborn. He's stubborn as a mule," said Verde crossly.

The trio shared a look.

"Fine. Brother kept an incident file as a warning why Byakuran is never allowed a dry spell. Ever."

Reborn raised his eyebrow. And then he had to work very, very hard not to laugh his ass off when he saw what happened.

A sleep deprived Verde, a bored and horny Byakuran, and a disbelieving group of Fon, Spanner, Shōichi, Tsuna and Haruto all watched as the two lightnings duked it out with armies of marshmallow Peeps.

"What the hell is going on?"

"Sho-chan! Check out my new army. Aren't they adorable?"

"I will defeat your pathetic army, you ingrate!"

"...I... there are no words for this. Right, Shōichi, you deal with the marshmallow idiot. Fon, you corral Verde into a room to sleep it off. Spanner, help me build a microwave gun and so we can blow these damn things to hell. Haruto, get working on dinner."

"Yes sir!"

"God this is going to be a total pain in the ass to clean up..."

Reborn was cracking up.

"So what was with the microwave gun?" asked Reborn.

"Marshmallows inflate when inside a microwave for at least a minute," said Haruto. "Since there was no way Verde would have bothered to remove the soft quality of the sugar, it was unlikely they would have any defenses against it. That and he wasn't about to expose anything in the labs to large quantities of water to dissolve them."

"How long did it take you to clean it up the mess?" asked Reborn.

"A week. I don't know why but those idiots animated over two thousand of the damn things," said Haruto, twitching.

"And they didn't die if destroyed, oh no. They combined with each other to the point that they made new armies," said Fon twitching.

"And Byakuran came up with it out of boredom. When he realize Verde was too tired to think straight he jumped on it," said Haruto. Verde grumbled under his breath.

"And the only reason he went through with it at all was because Shōichi, Spanner, and Tsuna were all at a tech conference, while Haruto was busy dealing with Belphegor," said Fon.

"What exactly is Haruto's relationship with that psycho anyway?" asked Reborn.

"Belphegor isn't used to people actually listening to him, and then telling him he's not an evil monster. The fact I don't dismiss him as a nuisance like everyone save Mammon does meant he attached himself rather quickly. Especially when he found himself curled up next to me one morning," said Haruto.

"He's not used to being given positive physical affection, though Tsuna made it clear he wasn't getting anywhere other than second base until Haruto is at least sixteen," said Fon. "When he's actually calm, he rather tolerable to be around. He was probably very lonely for a long time."

"There's also a standing order in the Varia that states whenever the Prince is impossible to deal with that he is to be shipped straight here, so Haruto can calm him down," said Verde amused.

Reborn looked at Haruto.

"He acts like a lazy cat, and I treat him like a friend. That and I feed him. Mama doesn't mind so long as he behaves," said Haruto.

"Not my problem," said Reborn after thinking on it. Belphegor was technically part of the Vongola, and if Haruto felt like catering to the bratty prince it wasn't his place to say. "Though how is he going to react when you finally meet a girl?"

Verde snorted.

"You really think he's going to let a girl get close?"

"One word: surrogates," deadpanned Haruto without hesitation. Reborn choked on his coffee. "Besides, I'm planning to have the same deal brother has with Mukuro and Hibari once we hit that stage."

"What deal?"

"They have a sparring session and the winner tops," said Haruto. Reborn choked again.

Tsuna was running late, as Haruto had gone ahead early today to help Hibari with his paperwork.

"Oof! Sorry, Kyoko-san," said Tsuna.

"It's fine, Tsuna-san," said Kyoko. She knew of him, vaguely, through her older brother.

Ryohei had tried to get Tsuna to join the boxing club, and he declined. However Tsuna came back an hour later in a different outfit and offered to fight him in the ring, since it was unlikely he had any decent opponents in the club. He was the most enthusiastic member of the boxing club and he often joined Tsuna and Haruto on their morning runs...and sometimes the evening ones too.

Ryohei had been surprised when Tsuna and even Haruto joined him in the ring, but once he got over it he was really happy. They made a point to come by at least once or twice a week to give him a decent match.

The fact Tsuna and Ryohei bonded over the joys of being the older brother meant they were rather close. They wouldn't hesitate for a second to jump into a fight to protect their siblings.

Some people might think Haruto was Tsuna's Sun Guardian... but they would be wrong. Ryohei was.

He went to school, unaware of the headache about to head his way.

A few hours later, at lunch...

Mochida stomped up to Tsuna's desk and loudly declared "I challenge you to a duel for Kyoko-chan, Sawada!"

Tsuna blinked, slowly putting his chopsticks down and staring at Mochida with disbelief.

"Why?"

"Everyone knows you're going steady with her," he said as if it were obvious.

Haruto suddenly snorted in amusement. Tsuna looked at him.

"Brother, it seems people think you're dating Kyoko because you're often seen around her house," he explained.

"Gods, not that stupid rumor again! The only reason I go there is to help Ryohei with his homework...he's so focused on his boxing that his grades slip, and I get paid with free food to keep him from falling below a C," said Tsuna exasperated.

Mochida didn't believe him.

Tsuna sighed.

"If I agree to fight you, will you drop this ridiculous idea?" he asked.

It wasn't that he had anything against Kyoko... it was just that reminded him and Haruto way too much of their mother for them to even consider a potential romantic partner. Besides, Haruto had Belphegor, who was a needy, jealous thing that would take it very badly if he dated anyone else.

Not that he would. The bratty prince had long since grown on the two.

Tsuna sighed.

He didn't enjoy fighting civilians all that much...namely because his training put him so far and above most "normal" people who couldn't even handle Kyouya in a forgiving mood and bored.

However he disliked the way Mochida had just decided on his own that Kyoko was his, and that he had every right to 'win' her from Tsuna simply because he was tutoring her brother.

Which meant he had just earned a spot on Tsuna's "list of people who deserve a mild lesson" list.

Reborn was almost certain to enjoy the show at least.

After school...

Seeing the sword and armor on the ground, Tsuna rolled his eyes. He wasn't going to be fooled by such an obvious trick...he could see the floorboards bending slightly enough to indicate that they were under an unusual amount of weight.

Did they really take him for an idiot?

Sighing in exasperation, he took a stance.

"Let's get this over with."

Mochida charged like a wild bull. It was so obvious and full of holes that Tsuna barely did more than take a step to the left to dodge. His movements were all open and too direct.

And this was the state of their kendo club? How did this idiot make captain?

With a single punch to the solar plexus, Mochida coughed once before keeling over out cold.

Stunned silence filled the gym.

"And that is the difference between our skill level. Though perhaps Kyouya should really look into the state of our fighting clubs if this is the best our kendo team can offer," he mused loudly enough to be heard. Seeing the stunned looks on the faces of the other team members, he tossed them Mochida's sword. They almost didn't catch it.

Takeshi was a better fighter than this idiot, and he was more interested in baseball.

He left the gym with a bored look on his face.

"Nicely done, putting that puppy in his place."

Tsuna didn't have to turn to see who was talking.

"Well maybe if the mutt hadn't tried to challenge an alpha wolf to an omega under his protection..." said Tsuna smirking.

Because seriously, Mochida was a pampered house dog to his alpha wolf. And Kyoko didn't seem to mind the designation of Omega when he explained the social structure of the pack to her. She was to be kept informed when her brother was involved with Tsuna's pack, but not to be involved unless absolutely necessary.

It gave her something in common with Nana, who was more than happy to teach her some tricks to help keep the boys fed.

Kyouya hummed, clearly pleased Tsuna hadn't held back when a mere dog challenged him. He had been quick, efficient and he made a clear point without useless movements.

There was a reason why he acknowledged Tsunayoshi Sawada as an equal predator, and would humor him when it came to protecting the Pack.

"By the way, if that was seriously the best the kendo club has to offer then perhaps they could use some...remedial...training," said Tsuna impishly.

Kyouya's answering grin was positively demonic.

"That is surprisingly vindictive of you, Tsuna," said Reborn amused.

"Like you didn't enjoy the show. I've heard about your sadist tendencies Reborn."

The Sun smirked and jumped onto Tsuna's shoulder.

"So where to next?"

"I heard a decent movie came out. You interested?"

"Why not. What about Haruto?"

Tsuna had his custom made phone and texted his brother and the others.

"They'll meet us there. I could convince Mukuro to hide your espresso once we reach the theater...as long as he keeps Ken from eating all our snacks again."

"I would have thought you'd get the pirated copy and watch it on a projector or something."

"Where's the fun in that? Half the fun of going to a theater is getting a spot in the back and then throwing popcorn or ice cubes at people who are really annoying during the boring parts! And with your skills, we could make a game of how many people we annoy," said Tsuna grinning.

Seeing the look of evil amusement on Reborn's face, he knew he had his interest.

And yes, they did annoy the hell out of the other patrons (without being busted for it) by throwing ice cubes down the backs of the really loud and obnoxious people who were talking too loudly or had their phones out.

Mukuro had great fun putting people into illusions and then having them walk into walls or into the guard rails after the movie was over.
