assyrian, I don't know if you're back online yet, but since I just finished your request!fic, I'll just post it anyway. The request was Rikkai/Seigaku interaction with either a food fight, water slides, or extreme sports. All this has is the food fight - unless you count card games as extreme sports which they very well could be, considering who we're talking here.
Title: Chaos Theory
Author: helga
Rating: PG
Characters: Rikkai, Seigaku
Summary: In which the Rikkai and Seigaku regulars go on a joint camping trip. Uh-oh.
Disclaimer: I own nothing.
Kaidoh leaned back against the wall of the cabin, closed his eyes and attempted to shut out some of the noise around him.
He was quite unsuccessful.
"Our team-mates are quite loud, don't you think, Kaidoh-kun?"
Kaidoh opened his eyes to look at Yagyuu Hiroshi, who was sitting next to him, leaning on the wall as well while dispassionately watching the rest of the gang.
"Yes," Kaidoh agreed shortly. There wasn't much else to say, really.
They watched the goings-on around them in silence for a while.
"That Kikumaru-kun... He really is something else, is he not?" Yagyuu finally said.
Said redhead was currently seated some way away from them across the merrily burning fire, intently whispering with Yagyuu's doubles partner. Both of them very spotting surprisingly similar and somewhat alarming conspiratorial looks.
"After all, the first time we played, Niou almost concussed him," Yagyuu continued. "And now, they're getting along that well." He nodded towards them.
Kaidoh frowned. "That," he pointed out, "was you."
Yagyuu turned to him, blinked a little and adjusted his glasses with his index finger. "Ah. Right," he said.
The discussion was interrupted right then, though, as Kirihara popped up at Kaidoh's side. Dropping to the ground next to him, he crossed his legs beneath him, leaned his elbow on his knee and his chin in his hand and stared at Kaidoh.
Kaidoh started, and drew back a little. "What?" he snapped.
Kirihara grinned. "You're a second year like me, aren't you?"
"Yes."
"So who d'you think is going to be the Seigaku captain now that the third years are retiring? You or that Momoshiro?"
Kaidoh looked over the fire, where Momoshiro was sitting directly across from him, next to Yukimura. He had been practically permanently attached to the side of the Rikkai captain ever since the food basket had been given into his care at the beginning of the trip - Inui-sempai and Yanagi both had agreed that this was the best way to keep the food at least somewhat safe and ensure that there was at least some left the following morning as well.
"I don't know," Kaidoh said shortly. There was no way he was going to tell Kirihara he thought it was going to be that idiot.
"Huh." Kirihara let go of his chin, leaning his head back and fixing Kaidoh with an annoyingly smug look. "Maybe it won't be either one of you." He nodded towards Echizen, who was seated some way off from the rest of them, boredly sipping a can of Ponta.
Kaidoh frowned, and Kirihara snickered a little, but then seemed to lose interest in him.
Across the fire, Kikumaru and Niou had apparently started a minor food fight; the two of them were cheerfully flicking a grain of rice here and a piece of the sushi Kawamura had provided there at each other. Kirihara looked on with interest for a while, and then grabbed his own half-full plate and walked over there. Apparently not happy with simply flicking small pieces of anything on anyone, he promptly turned his plate over and emptied it over Niou's head.
Niou looked up, and without even brushing any of the food off, flew up and grabbed Kirihara into a headlock. Kikumaru came to his aid not many seconds later, both his own and Niou's plates balanced in one hand, and started cheerfully stuffing their food down Kirihara's shirt. It probably would have been easier hadn't Kirihara been squirming and trying to worm himself out of Niou's grip so violently.
The noise and the general racket the three of them were making had by now attracted the attention of mostly all their team-mates as well. Marui jumped up from his place by the side of Yukimura which Momoshiro wasn't occupying to angrily declare that it was absolutely indecent to treat food of all things this way, couldn't they fight with something else instead, there were lots of rocks laying about everywhere wasn't there, and Oishi-sempai, attempting to break them up, was soon pulled into the fight himself.
Yagyuu, meanwhile, was watching the whole thing with mild interest. Kaidoh saw him surreptitiously pick up the remaining piece of sushi from his own plate and discreetly fling it, not at the fighters, but at Kawamura-sempai.
Kawamura looked around in surprise at first, but Yagyuu was once again the perfect picture of mildly interested gentlemanly calm, so when Momoshiro handed him a racquet he charged right into the actual fight instead. "I will burn you with my fish!" he yelled in English, waving the racquet with one hand and some sushi with the other.
Kikumaru looked up as he charged, let go of Oishi's head and Kirihara's arm and jumped out of the way, somehow managing to fling the remaining piece of sushi in his hand in the completely wrong direction as he did.
It landed on Sanada's cheek.
Sanada looked up from the card game he had been in the middle of and turned to glare at Kikumaru.
Everyone, even Kawamura, went quiet.
"Umm. Oops?" Kikumaru said.
Sanada was still glaring. Everyone else looked on in silence, until it was interrupted by a derisive snort.
"Too slow," Echizen said. "You should have been able to dodge that, Sanada."
Sanada's glare turned to Echizen.
This time, the ensuing silence was interrupted by Yukimura.
"He does have a point, you know, Sanada," he mused, his gaze thoughtfully straying between Sanada and Echizen.
Sanada looked at Yukimura for a second, then closed his eyes, drew a deep breath and turned back to the card game. "I believe it was your turn, Tezuka," he stated in a voice of forced calm.
The food fight apparently died down with that, and the participants returned relatively unharmed to their seats - Oishi and Kawamura looking embarrassed, Niou and Kikumaru like they were trying hard not to burst out laughing, and Kirihara pretty much indifferent.
Kaidoh turned to watch the card game for a while instead, trying to figure out what exactly they were playing, but to no luck. Apparently, they were playing in pairs, Fuji and Sanada against Tezuka and Kuwahara. The interruption hadn't apparently upset Sanada to much, since as the game wrapped up, it turned out the Fuji-Sanada team had won.
"Anyone else want to play now?" Kuwahara asked, gathering all the cards together.
"I could play," Yukimura said. "Anyone else?"
"Me!" Momoshiro and Marui declared in stereo, still apparently unwilling to stray too far from the food.
"That's three then. Anyone else?"
"I'll play!" Kirihara had jumped up from his seat, and was watching Yukimura with a strange glint in his eyes. "I'll definitely defeat you this time, Captain!"
Yukimura turned a predatory smile on Kirihara. "Let's play, then," he said, taking the deck of cards from Kuwahara and shuffling them. Kaidoh suddenly had the feeling it was probably a good thing no one had flung any unwanted sushi on him.
Next to him, Yagyuu shifted a little. "This is fun, don't you think, Kaidoh-kun?" he said in a dead-pan voice. "Our teams should do this more often."
"Hmm," Kaidoh said indistinctly in reply. "Whose idea was this anyway?"
"I do believe it was our data men who suggested a joint gathering of some sort." Yagyuu nodded towards Inui and Yanagi. The two data men were seated away from the rest, Inui frantically scribbling in his notebook and Yanagi watching everything very intently.
Kaidoh frowned, suddenly recalling something Inui had been talking about recently. "Perhaps... They're testing Inui-sempai's chaos theory," he said.
Yagyuu raised an eyebrow at him.
"Something about 'the amount of chaos experienced increasing exponentially by every one tennis player and every one tennis team added'," he said, repeating all he remembered from memory.
"I see," Yagyuu said.
"And..." Kaidoh paused to think for a while. "Something about... an added factor of complete uncertainty if Niou is present."
"Of course," Yagyuu said, nodding in understanding.
Kaidoh sighed and leaned back against the wall again.
Directly across from them, the card game was in full swing, Yukimura and Momoshiro against Marui and Kirihara. Kuwahara, Kawamura and Oishi were watching over their shoulders.
Next to them, Fuji was eyeing the left-over sushi on his plate thoughtfully. Kaidoh watched as an amused smile spread across his face as he nudged Sanada and handed him the plate. Sanada looked at it for a while, and Kaidoh could have sworn he saw a faint smile flicker across his face as well as he picked up the piece of sushi and flung it at Echizen.
Echizen spit out the soda he'd been drinking when it hit him.
"There's still a lot for you to learn. Echizen." Sanada gave him an impassive look and turned back to Fuji, who was by now looking thoroughly amused.
Echizen glared at Sanada's back.
Inui-sempai was wrong, Kaidoh decided. It wasn't a Niou-factor of complete uncertainty they had to take into account at all - it was an uncertainty factor of everyone here, really. They were all too insane to know certainty if it hit them with one of Echizen's Twist Serves.
"Next time, I'll just have that Inui juice instead," Kaidoh hissed to himself, referring to the method that had been used to get everyone to attend the trip.
Yagyuu just gave him a look.
Kaidoh suspected he knew that Kaidoh was, most likely, lying.
