Disclaimer: I do not own Prince of Tennis or its characters, but I will use them for my stories and to entertain my readers.

A/N: This has been something that has been on my mind for a while… Why didn't Jackal just say no? So as I was pondering this question, this story idea popped into my head. I hope you enjoy. There will be no actual pairings in this story, it is just Rikkai Dai being… well them. SugarTensai, it's finally here! Enjoy minna!

Chapter 1 – I Said No!

"NO!" A bellow came from the tennis courts at Rikkai Dai Fuzoku Chuu before the clatter of a racket hit the ground. Now normally everyone would think that it was the second year ace throwing yet another temper tantrum, but shockingly it wasn't. It wasn't even the bubble blowing self-proclaimed tensai, or Niou pretending to be either one of them. No, this was from someone no one expected to shout the negative word or to throw down his racket in a hissy fit… Jackal.

Heads whipped around to gape at the four lunged iron wall as for the first time anyone could recall, he denied someone or something and was completely serious about it. Ok, he might have been serious about it in the past, but he somehow always got dragged back in, but this time was different. It was written on his face and the tenseness of his body… he was deadly serious and he would not give in this time.

"But Jackal…" Marui blinked as he walked up to his doubles partner with a huge grin on his face, wholeheartedly believing he would be able to convince his friend to do what he wanted.

"I SAID NO! As in not going to happen, not on your life, never gonna change my mind and you can't make me!" Jackal screamed breathing hard and looking for all intents and purposes like he had just experienced a psychotic break.

Marui's jaw dropped to the ground and he couldn't believe what he was hearing. This wasn't Jackal, his friend, partner, and all around lackey. It couldn't be. The half Brazilian must have been possessed by a ghost or evil monster. Jackal never said no and meant it. Could it be because he was only half Japanese that he was more susceptible to the influence of ghosts and spirits… it was definitely something the tensai would have to look into because honestly the look on his friend's face right now frightened him.

Looking behind him at everyone around the courts, Marui could see that everyone was in shock. Even Kirihara was cowering in the corner behind Yukimura and crying, "Don't let evil Jackal kill me Mura-buchou. You have to protect me! His eyes will burn me alive and there will be no hope for me!" The second year ace was covering his head and trying not to look at the defensive specialist. Really there was no reason to go that far. Jackal must be having a bad day or something and it wasn't like his friend's eyes could really burn someone alive.

"Did something happen in school today? I think if you just…" Marui tried talking to his friend again and once again it didn't work.

"Don't tell me what to do! If you are trying to placate me and calm me down, it isn't going to work!" Jackal yelled.

At a loss as to what to do, Marui turned to the only two people that could probably help in this situation… Yukimura and Sanada. Surely they would be able to reach Jackal when he couldn't, right? If nothing else, Sanada could slap some sense into that blasted bald head of Jackal's with an infamous torundoru.

Yes, by now the torundoru were truly infamous because all of the schools across Japan and even some around the world knew about the power slap the fukubuchou possessed and used on a regular basis. It was gossiped and talked about in dark corners and hushed whispers. Rumors spread about the power and magnitude of these slaps and some compared them to a 4.2 earthquake on the Richter scale. Yes, the rumors were vastly exaggerated, but these were middle school kids gossiping… what isn't exaggerated?

Yukimura saw the panicked looked that came over Marui as the tensai turned to him and Sanada for help and the buchou chuckled. In his mind it was best to let the redhead stew for just a little longer, to believe he was on his own, and to freak out just a little more than he already was… that was half the fun. However, even Yukimura was a little surprised that Jackal had exploded on the tennis courts like he had. That wasn't the half-Brazilian's nature and it showed he had been pushed to his limits, but the bluenette's attitude about limits were that they needed to be pushed and broken, and he really hated it when his tennis practice was disrupted like it had been. Someone would pay.

Glancing down out of the corner of his eye towards his friend beside him, Sanada could see the wheels turning and the enjoyment sparkling in those blue eyes of the tennis buchou; and he knew if he made a move too early, he would pay a hefty price. He may be able to torundoru most players, but he was no match for Yukimura when he was mad or upset or in sadist mode. It was best to wait and not move, not even twitch or breathe, until the bluenette took the first step. If that meant one of his tennis players had to suffer, well this was Rikkai and they had a sadist for a buchou and Sanada for a fukubuchou, the players should be used to suffering by now. Really when you are a student at that school, suffering was part of the student creed, and Sanada was pretty sure it was written in the student handbook somewhere. Briefly he wondered if the other schools knew how easy they had it… probably not. None of them would survive a week at Rikkai Dai. They didn't have what it took. He was pulled out of his musings when Yukimura took one step forward and then paused.

"Renji," Yukimura called out to his data specialist.

"There was a 97.4% chance of this happening eventually, but my calculations were a little off. I didn't expect it until tomorrow after tennis practice was over," Yanagi answered the unspoken question.

The three demons stayed where they were when they noticed two other players attempting to approach the upset teen. It really was a wonder why Jackal was still there and hadn't moved, but that could have been because Yukimura and Sanada were in front of the exit and in order to leave, he would have to go through them… his chances were (as Yanagi would say) only 1.2% that he would escape unscathed. It was probably safer to stay put.

Pushing up his glasses, Yagyuu calmly spoke to his friend, "Jackal, yelling like a madman and throwing a temper tantrum is not very becoming. You should act with more decorum on the courts." He realized too late that this was probably the wrong thing to say because Jackal turned around and literally growled like a wild animal at him. The only thing missing was foam at the mouth and the teen would be a rabid beast.

Niou shook his head, "Puri. Let me show you how it's done Yagyuu." Walking closer to Jackal, he placed his hand on the other teen's shoulder and smiled, "Now Jackal, we know you're upset but…" Nothing else was heard from Niou besides a yell as his hand was shrugged off and he was pushed away falling on his butt. This did not sit well with the trickster.

"Leave me alone!" Jackal screamed.

"We're gonna die! We're gonna die!" Kirihara wailed from his place in the corner still refusing to look at Jackal because he didn't want his flesh burned off.

Inwardly rolling his eyes, Yukimura plastered on a new smile that said, "I will take care of this and Jackal and he will learn to behave in the future; and if he ever disrupts practice again, he will forfeit his life." The bluenette moved forward with Yanagi and Sanada on either side of him as they approached the psycho tennis player, "Jackal, would you care to tell me what's wrong?" His tone of voice said there was no room to deny him or to argue, but he was in for another shock because what happened next never… and I mean NEVER… happened before in… well all of history. In fact there were reports that after this hell had in fact frozen over.

Seething, Jackal turned his furious glare at his buchou and snarled, "No, I don't have to. No, no, no, no, no, no! My answer is NO!" He pushed his way past the stunned three demons and ran out of practice. Yep, he had finally lost it and not even Yukimura was able to stop him; all hell had just broken loose and Jackal had defied nature… he was so dead.
