Thank you for the reviews, favs, and/or alerts. Also, thank you for deciding to continue reading this story.

I don't own tenipuri, nor it's characters, nor Shitenhouji, nor Rikkaidai, nor Oshitari family. I only own my OCs.

Sorry for bad grammar and typos.

This chapter goes longer than I thought, thanks to the randomness. Enjoy!

Ch2: KISS Principle

"So here we are-de yansu, " Said a brown haired Rikkaidai freshman who accompanied the Shitenhouji boys from the school gate to tennis club entrance. "Please wait a moment. I'll inform Yukimura-buchou that you're already here." The boy called Urayama excused and hurriedly ran across the courts to meet the regulars in yellow jerseys.

"Wow! This is amazing!" Kintarou exclaimed in excitement as he looked around.

"Indeed it is." Shiraishi nodded in agreement as he patted the redhead.

"This is truly amazing!" Koharu repeated the redhead, but –of course- with different meaning from Kintarou. "They got some cuties here~" He mused in his infamous lock on pose.

"Hey, that's adultery!" Yuuji protested.

Koharu pouted as he heard the accusation. "But they are really cute, you know? It's not my fault that my girl instinct reacts toward them!"

"That's mean! You're the only one for me and I thought you also felt the same way!"

"Let's break up then!"

"Eh? Wait, Koharu!"

Koharu looked away and continued checking out Rikkai members, while Yuuji dramatically felt onto the ground sulking.

The team couldn't help but laugh watching another comedic show from the duo.

"They don't really break up, do they?" Kenya asked as he wept his tears of laughter.

"Whatever. I don't really care anyway." Zaizen replied monotonously.

Well, Kouki could only hope that these two comedians were only acting to amuse the party, otherwise their ultimate owarai pair was in doom.

"It seems that you're enjoying yourself here."

Hearing the comment, everyone looked around to see who had talked just now.

"I'm Rikkaidai boys' tennis club's captain Yukimura Seiichi. Nice to meet you." Yukimura greeted with warm smile.

"Sorry for troubling you," Osamu said. "We're looking forward to our joint practice."

"So do us. I deeply apologize that our coach can't present. I, as the captain, will lead our team in this practice on his place instead. " Yukimura politely bowed.

"Nah, it's okay." Osamu shrugged.

"Glad to hear that. Then, let's move to the court, shall we? I believe our members are really excited to meet you."

Yukimura led the Shitenhouji group entering the tennis club and walked them across the courts. They stopped in front of the club house and were greeted by the rest of Rikkai regulars.

"Everyone gather here!" Sanada shouted out, the non-regular members gathered in front of him at once in ordered lines.

"It's really impressive how Sanada can manage the boys. I wonder if I can be like him someday." Koishikawa commented, tipping his own chin.

Chitose smirked hearing his friend's saying. "Well, in a thousand years maybe you can become like him."

Koishikawa Kenjirou was famous from being unnoticed and forgotten after all.

"As you've know before we'll have a joint practice with Osaka's Shitenhouji tennis club for two days starting from today," Yukimura announced to his fellows then he turned to see Shitenhouji. "I want to officially introduce our regulars. I'm Yukimura Seiichi: captain, Sanada Genichirou: vice-captain, Yanagi Renji, Marui Bunta, Niou Masaharu, Kirihara Akaya, and lastly Yagyuu Hiroshi, he's not here though, I believe he still has something to do with the student council and will join us soon."

Akaya looked confused and started counting with his fingers. "But, Buchou... I thought we had 8 regulars in total."

"Akaya is right, Seiichi. We have 8 regulars in total and you only called out 7 names." Yanagi stated while scribing on his data book. "I feel like you have already mentioned every single one of us, though. That's strange."

"Then maybe we actually only have 7 regulars in total!" Marui concluded genius-ly, not noticing that the one whom they forgot was no other than his own double partner.

Niou snorted. "We couldn't have entered any tournament with only 7 regulars, idiot."

"I'm not idiot. I'm a genius and the universe knows that!"

"And the universe knows that having read hair is a sign of suffering a kind of mental retardation." Niou stuck out his tongue.

"What? Mental retardation? Is that a deadly disease? My hair is also red! Is that mean I'm gonna die?" Kintarou freaked out.

"I believe Niou is referring to phenylketouria or PKU. It is an autosomal recessive metabolic genetic disorder characterized by a deficiency in the hepatic enzyme phenylalanine hydroxylase (also known as PAH). This enzyme is necessary to metabolize the amino acid phenylalanine to the amino acid tyrosine. When PAH is deficient, phenylalanine accumulates and is converted into phenylpyruvate, which is detected in the urine." Yanagi answered Kintarou's question, or so he thought.

Akaya jaw dropped. "Yanagi-senpai… I don't understand what you are talking about. Are you using English or some other alien language?"

Ignoring the talk about diseases and mental retardation of Marui, Jackal sulked in corner, whining on how his friends forgot him.

"Anyway…" Shiraishi coughed. Further talk about this PKU would only driven Kintarou crazy and that would likely ended up bring chaos for all of them. "I think we Shitenhouji also has to officially introduce our team."

"Oh right." Yukimura nodded then threw a smile to make his team shut up.

"I'm the captain Shiraishi Kuranosuke," Shiraishi began. "These are Oshitari Kenya, Chitose Senri, Ishida Gin, Konjiki Koharu, Hitouji Yuuji, Zaizen Hikaru and Tooyama Kintarou. Our coach Watanabe Osamu and manager Oshitari Kouki."

"Nice to meet you! Nice to meet you!" Kintarou greeted cheerfully, seemed that he had forgotten about the red hair disease at all.

"Wait, you don't have vice-captain?" Sanada asked.

"Ah, I almost forgot him. Vice-captain Koishikawa Kenjirou." Shiraishi added as if it was nothing.

Koishikawa then joined Jackal in the shady corner and whined together about how they were forgotten by their teammates.

"At least Shiraishi mentioned your name," Jackal patted Koishikawa's shoulder. "They didn't even bother to say mine."

"But not all of them acknowledge me as the vice-captain. They think Kenya is the vice-captain and forget my presence." Koishikawa sighed.

"They unexpectedly get along well." Kenya commented as he watched the sulking duo.

Gin nodded in agreement. "You're right."

"How about suggesting Osamu-chan to throw them together in random double matches then?" Chitose suggested.

Zaizen rolled his eyes. "I think you better not to that, otherwise they'll become Jimmies #2."

"Have you done with the chit-chat yet?" Osamu finally spoke up. Boys were only boys after all. They would have kept talking like this until the sunset if he hadn't stopped them. "We'll have to proceed to the training. Today's training menu will be sparing matches between the regulars and joint basic practice for the non-regulars. I'll try to mix Shitenhouji and Rikkai training menus together. Now, start with the warming up!"

"So you're the Shitenhouji manager?" Yukimura asked when Kouki handed him the Shitenhouji order for today sparing matches.

"I'm Oshitari Kouki. Nice to meet you." Kouki made a little bow to Yukimura and the rest of 3 demons behind him.

"By Oshitari name, are you related to the regular Oshitari Kenya?" Sanada questioned.

"Yes, we're cousin."

"Oshitari Kouki, 3rd year," Yanagi started reading his data. "Born in Osaka on November 9, cousin of Shitenhouji's Oshitari Kenya and Hyoutei's Oshitari Yuushi. 162 cm in height, weight is unknown –thought she is believed to be heavier than she looks-. Assigned as Shitenhouji boys' tennis manager since August 12. In relationship with Shitenhouji tennis club's own captain Shiraishi Kuranosuke since Au-"

"AAAH! You don't have to read it loud, Yanagi-san! Moreover, how could you know those trivial things?" Her face went red.

"Ah… So you're Shiraishi's…" Yukimura chuckled. "To think again, now I understand what he meant at that time."

"What do you mean, Yukimura-san?"

"When we were talking about flower, I once asked Shiraishi about his favorite one. Guess what his answer was."

"Eeeh?" It couldn't be! Shiraishi wouldn't have mentioned that one, right?

"Chrysanthemum, isn't it?" Unexpectedly, it was Sanada who answered. "Her given name is most likely consisted of two kanji and the last one is probably kiku for chrysanthemum."

"As expected from someone who advances at kanji and calligraphy." Yukimura complimented. "Shiraishi is a quite romantic type of person, isn't he?"

Sanada looked at his friend with his usual straight face. "Is that so? For me it's just like a kind of word game."

"It's a quite interesting data." Said Yanagi as he scribed down the new data in his book.

If Kouki's face had been as red as her name a while ago, now her face lost its color. These so called three demons were real life demons. How could they talk something embarrassing as if it had been nothing?

"Buchou! Yagyuu hasn't shown up yet. We can't start the double matches without him!" Niou called out from the other court.

"That's strange. The student council meeting should have finished 10 minutes ago while we were warming up." Yanagi said without even checking the clock.

Sanada sighed. "Tarundoru. That's quite troublesome. I'll tell some of the freshmen to look for him."

"I'll help you search for him." Kouki volunteered.

"Oshitari-san, you don't need to do that. This's our responsibility after all."

It's okay." She shook her head. "Besides I feel sorry for the freshmen if they have to skip the practice."

"Sorry for troubling you then. Based on my prediction, Yagyuu should be somewhere near the eastern gate," Yanagi quickly drew a simple map on a piece of paper then handed it to Kouki. "Just follow this direction."

"Okay. Thank you very much Yanagi-san." She bowed then ran exiting the courts.

"Shitenhouji sure has a handy manager in their team."

"No, I think she does that only to escape from us."

"87% that Seiichi's intuition is true."

It was hard to find someone in a place she barely knew, but at least she could have sometime alone to calm down. Staying with those guys was mind scarring. It hadn't been like they had done it in purpose of teasing her or something. They had only been trying to be friendly to her, that's all… Although it seemed that everyone was really in mood of talking about her relationship with Shiraishi today.

Anyway, she had to find Yagyuu soon or else the practice would have to be delayed. She was glad Yanagi had given her a map, otherwise she would have probably gotten lost here. Wait, did that data man also know that she was easy to lost direction?

That was… somewhat scary.

She wasn't even a player and he had so many information about her. She wondered how specific his data on the regulars would be.

'Forget about that!' She shooed away the thought and took a look at the map. Let's see… The eastern gate was just some meters away from the middle school building. There would be trees behind the building. The eastern gate was right next to the biggest tree.

Finding the biggest tree wasn't really hard. And as soon as she spotted the tree, she saw a figure in yellow jersey. That should be Yagyuu. She walked approaching him happily, thinking that she had accomplished her task quite well, only to find that the gentleman wasn't alone. There was another person... a girl? They were very close; especially the faces… and the lips were…

It took some time until she realized what she was seeing.

They were kissing!

Kouki gasped, blushing furiously as the idea about what was happening struck her head.

"Somebody's watching…" The light brown haired girl suddenly said as she broke the kiss.

"A…" Yagyuu looked away to see Kouki and in a blink he remembered something important. "Crap! I forgot about the practice…"

Seeing another couple kissing reminded Kouki about Miki and the boys' saying about first kiss. Thanked to this, she couldn't focus on the practice matches before her eyes. She sighed and looked at her the practice report she had been writing while observing the matches.

There were 2 double matches and 5 single matches in total.

For the doubles, she admitted that Osamu and Shiraishi had thought out some wonderful strategies to counter attack Rikkai's double pairs.

The first double was between Marui/Jackal pair and Koharu/Yuuji pair. It was amazing that Koharu and Yuuji were still able to play together so well although they were in fight. They continuously fighting over Marui, making the redhead tensai (somehow) lost both his temper and stamina. On the other hand, poor Jackal was forgotten.

The other double match was Niou/Yagyuu pair vs. Kenya/Zaizen pair. This time it was Kenya who lost his temper. It was revealed that Niou and Yagyuu had been switching place and it bothered the speed star. Zaizen was able to keep his mind calm and this reduced the tricks' effect by half. Thanked to him, Kenya could eventually catch up the speed of the real laser beam from the real Yagyuu and return it.

Speaking of tricks, it was actually Niou whom she had searched for a while ago. No wonder why the gentleman at that time hadn't looked bothered at all when being caught ditching practice and flirting girl.

"Kiss."

Kouki felt her heart stopped beating for a while in surprise of hearing that voice that came from right behind her. She quickly turned around to face the Rikkai girl she met earlier. The one that had been with Yagyuu-Niou back then.

"It's beyond people expectation that ones can reach perfection in a mere simplicity." The light brown haired girl said again in monotonous and slow voice, much talking to herself instead of to Kouki, as she watched the single match trough her glasses.

Kouki could only blink, looking at the other girl speechlessly.

"What's with that look?" The girl turned to Kouki. "Of course I am talking about the KISS Principle in perfect tennis that Yukimura-san and your captain are currently playing."

"Eh?"

"Seems that you were thinking about a different kind of kiss…"

Kouki mentally facepalmed. First the phone call with Miki that had caused a kind of insomnia, then the ruckus on the train, intimidating conversation with the three demons, accidentally having witnessed some kiss scene that had distracted her though the practice, and now she was picked on by a strange girl she barely knew.

She could only hope that today wouldn't become even more complicated for her…

no offense to those who either have red hair or suffer PKU. My biology teacher when I was in high school once said that having a reddish hair –while you're supposed not to have red hair- was one of the sign of suffering PKU. Really I don't mean to offend any of you and I'm sorry if this hurt you.

KISS Principle : "Keep It Simple, Stupid". It is basically the same with Shiraishi's Bible if being applied in tenipuri (somewhat flashy) tennis.

It's been a while since my 10 Things I Hate about Niou Masaharu crack fic ended. I miss Niou's evil tricks. I also miss torturing the poor Rikkaidai regulars. Oh, if you read the 10 things story and still remembered about one of the chapter where Niou (or literally I as the writer) tortured Yagyuu by impersonating the gentleman, the big tree here was actually the same with the one I wrote there XD

As you've noticed, I threw in a new OC from Rikkai here. The name is Takamiya Masami. I'll continue referring her as the light brown haired girl or the glassed girl though, till Kouki has a proper jikoshoukai with her.(She will appear more in later chapters) I want to make her act like a kuudere and FYI she talks like Touya Rima from Vampire Knight (It's hard to portray it in the story so I just tell you straightly about this).

Review, pretty please? I really want to know your opinion about this chapter. Were the characters too OOC? Any suggestion or idea? ConCrits, perhaps?

Expect some sweet romantic scene with Shiraishi (or something fluffy like that) on the next chapter!
