A/N: Another story. Hooray! I'm excited about this one. It has a twist of comedy, fantasy, adventure and romance, of course. Err, it has a bit of yaoi in it, if I may say so.

Warning: A bit AU. A bit OOC. Gender bender. Female Fuji (Princess Syuurika, that is!)

Pairings: Pffft. Let's just see as this story goes on. But I'm open for suggestions. :D

Chapter One

I'm A Mermaid!

"…Mamushi, you idiot!"

"What did you say?"

"Do I have to repeat it myself? MAMUSHI IS AN IDIOT!"

"You want to fight you blockhead?"

"I'm on for it!"

Two sophomore students, one wearing a green bandanna and the other had a black hair with violet eyes were having their usual bickering.

"The two of you, stop it before Tezuka would notice you." Said the green-eyed vice-captain of Seigaku as he was struggling to stop the two sophomores from killing each other.

On the other side of the court, Kikumaru and Echizen were playing a board game. While Kawamura Takashi, aka Taka-san and Inui Sadaharu, the Data Man were discussing something as Inui was scribbling at his notes.

"Nya! O-chibi! Mada mada dane, you lost! Bui, bui, bui, bui!" Kikumaru Eiji, an acrobatic player of tennis club, exclaimed jumpily and he was having a V sign as he defeated Echizen in some sort of a board game.

"Che. I should have declined his offer when he asked me to play Snakes and Ladders." Echizen Ryoma, the super cheeky rookie, muttered as ticked his cap down to cover his eyes.

The heads all turned to the entrance of the tennis court as they heard the door opened followed by a baritone voice of their approaching buchou with his usual stern-looking face. The two sophomores both shrieked in fear as they looked at their buchou.

"What is the ruckus all about?" He asked, still wearing the stoic and emotionless façade.

Kaidoh and Momoshiro, the two bickering sophomores gulped in fear and were sweating a lot as they turned their eyes away from their intimidating buchou.

"ALL OF YOU, 50 LAPS AROUND THE COURT!" Tezuka Kunimitsu, Seigaku Buchou (captain) commanded.

"Tezuka, isn't it too many?" The ever kind and gentle fukubuchou (vice captain) of Seigaku – the mother hen, Oishi Shuichiro contradicted.

"They should know that the court IS NOT a place for fighting. They should keep that in mind."

Oishi just sighed at his best friend's remark. He knew that he had lost in that argument already.

And so, the regulars, along with the non-regulars were now running 50 laps around the court as instructed by their beloved buchou. But of course, we should have not forgotten the threat of Inui's nauseating juices for those who would not complete the laps.

This was a usual sight for Fuji Syuusuke, a third year middle school student. Seigaku's hailed tensai, a beautiful man, Seigaku's number two, next to Tezuka Kunimitsu and a known sadist for his teammates.

He was running laps along with the Seigaku Tennis Club regulars and non-regulars as commanded by Tezuka. He was wearing his usual smile as his face was hitting by the rays of the sun. It was a nice day to train. The sky was clear and the wind's breeze was blowing naturally and swaying his hair.

But unfortunately, he was sweating a lot. They had been on a harsh training since the National Tournament was just around the corner, and they can't afford to slack off. And he had to work real hard, now that he had changed. Yes, he changed, right after his loss to Tezuka at the recently finished Intra-school Ranking Tournament. It opened his eyes that he wasn't serious enough with tennis. He just found it fun and thrilling. And he also thought that he could not go to the nationals with his triple counters alone, so he still had a long way to go since the participants in the nationals were all Tezuka-class players, meaning national-level player since Tezuka had defeated all his triple counters in just one play, much to his surprise.

"Where is the real you?"

He remembered that as Tezuka asked him that when they were still in sophomore. He didn't answer that, he was speechless. He didn't know what to answer.

Where is the real me huh?

He also asked to himself that sometimes. He really wondered WHERE his real self was.

Since he turned 15 he had been feeling a bit of uneasy. He also noticed that no matter how much training that he put himself with, he just could not acquire the body that most guys had. His was always slender and firm, just like a female whilst his other team mates, especially Tezuka had a really good psych worthy of an athlete. And he had been playing tennis all his life.

And what's worst, he didn't feel any attraction towards any of his female fans nor in any opposite gender. He had his eyes on men, which really confused him and had gotten severe when he turned 15. He never thought that he would be a homosexual. He, who had a high reputation at their school, was a gay! And who caught his attention? It's none other than Tezuka Kunimitsu, their beloved buchou that was why he loved to tease him. And he could not feel any homosexual tendencies in his body, rather, he felt that it was all too natural for him to have a crush on their buchou.

But he couldn't help but felt like throwing up. He had been bothered a lot by unexplainable things that were happening to him recently. He just couldn't figure it out.

After they had finished running their laps, they held practice matches to gauge one's abilities. After the matches, Ryuuzaki-sensei called it a day and dismissed them. It was nearly sun set. Due to the request of Inui to carry out the training menu that he had prepared for them, they had to extend their training for an hour.

As they were changing their jerseys into their school uniform in the club room, Fuji felt that his cheeks were burning hot as he saw the naked bodies of his team mates, much to his surprise. He was always seeing their naked bodies ever since their freshmen year, but just recently, he just felt like a girl who was seeing a man's naked body for the first time.

He tilted his head.

Calm down, Fuji Syuusuke, it's not like you haven't seen them topless before. He scolded himself inwardly.

And he also got conscious changing his clothes in front of them, with the regulars who were all guys.

Again, he tilted his head. He shouldn't be feeling this way.

He felt someone was behind him and turned around to see that Tezuka was there, revealing his bare chest, fresh from shower. He quickly looked away as he felt that his cheeks were now red, as in tomato red. Tezuka looked so hot in that state. He couldn't help but shot his eyes open as his blue eyes were wandering off along Tezuka's manly figure.

And Tezuka looked at him eerily.

I really wonder what's happening to me. He was now really puzzled.

He quickly walked out of the room without changing his jersey and his action was bewildered the whole regulars, even Tezuka. But before he even reached the door, Eiji called him.

"Ne, Fujiko-chan. Where are you going?"

"I have something to do outside."

He strode quickly after that, without looking at them. He went straight to the faucet and he splashed water in his burning face.

XXXXXXX

"Unyah! I was wondering what happened to Fujiko. He never acted like that, not even once." Eiji exclaimed.

"Maybe Fuji-sempai was intimidated by Tezuka-buchou's look." He whispered at Echizen's ear, but much to his dismay, Tezuka heard that.

"Do you want to run laps now, Momoshiro?"

"T-that's only a joke, Tezuka-buchou." Momoshiro was now sweating a lot of amount as his fierce captain was looking at him intently. And Kaidoh was hissing like a snake in the corner of the room.

Tezuka was now in deep thought. Why did Fuji have to rush off as he had seen him? The tensai had never acted like that before. It's not like he was the only one who noticed Fuji's strange behavior, their team mates noticed too, especially Fuji's best friend, Kikumaru.

"Eiji, did something happen to Fuji?" He heard Oishi asked his doubles partner.

"I don't know. I mean, he's acting a bit strange. He is always spacing out even in class." Eiji explained.

"Maybe Fuji-sempai is in love." Echizen voiced out as if it was nothing.

All the regulars turned to him, with their eyes all have that questioning look.

"Do you know something Echizen?" Momoshiro asked his kouhai, eyeing him intently. He was being careful right now; he didn't want to run any more laps.

"No, just an assumption."

"O-chibi! Don't make any conclusion like that! Only kami-sama knows how Fuji will deal with you the moment he heard you." Kikumaru pointed out as a matter of fact.

And all the regulars both agreed.

Only kami-sama knew how sadistic Fuji can be. If truth be told, he wanted to stick his nose out of other people's own businesses. But with Fuji, he just couldn't overlook the fact that he had been acting strange. With his sadistic tendencies, he was sure that Fuji was up to something.

"Echizen's assumption can be 56.8% true, however, let's just observe Fuji for a few more days before we can take some actions." Inui suggested. And with that, they were all dismissed.

However, he decided to stay. He wanted to wait for the tensai and asked him what was wrong directly.

He frown a little as he saw the way Fuji had looked at him earlier and the way that he was too startled upon seeing him, with only a towel covering his sensitive parts.

He was as curious as a cat now. He would found out what was the tensai was up to his sleeve.

XXXXXXXXXX

What the hell are you thinking Fuji Syuusuke? He really couldn't understand why he was acting like this.

This was the first. He had always been calm and collected. He had been feeling a bit uneasy since he turned 15, but that didn't mean that he had to act like this.

Damn! He cursed silently. His heart was thumping rapidly that it could explode soon.

He let time passed as he was trying to calm himself before he returned to the club room. He made sure that the regulars were out of the sight before he went back.

As he reached the club room, he quickly caught a glance of a bespectacled man sitting at one of the chairs in the club room. As their eyes met, he gave him his usual smile, and Tezuka being Tezuka just nodded to acknowledge his presence.

"Aren't you going home yet?" Fuji asked him, still wearing his usual smile.

"I'm waiting for you."

Fuji was shocked a little that he opened his eyes for a while. He didn't expect Tezuka to wait for him as he was always waiting for him.

"Do you want to discuss about something?"

"Aa," Tezuka slowly got up and faced him. Somehow, he felt uneasy with his gaze.

"What is it?" He tried to collect himself.

"About you." Tezuka answered without beating around the bush.

"What about me?" He asked innocently.

"You've been acting strange these past few weeks."

"And so?"

"The regulars are worried."

"I-" but before he could answer, he felt stinging pain in his stomach and legs. He screamed. The pain was unbearable. It was his first time experiencing it. As he couldn't handle the pain anymore, he fell on his knees, clutching his stomach. He couldn't describe the pain, but it really hurt him a lot. He felt as if he's dying. And he can't breathe properly either.

Tezuka looked at him in horror as he froze for a while where he stood before he went to Fuji and hold him. He was struggling in pain. And his flesh felt like going to explode anytime.

"I-itai…Tez-zuka," Fuji cried out in pain. And Tezuka didn't know what to do.

"Te-tezuka! H-help…..me..It..really…hurts.." Fuji begged. It was his first time seeing Fuji in this state.

Fuji was feeling that her chest was growing, as he had felt a really stinging pain in every part of his body. And just as the clock ticked at exactly 6:00 in the evening he went black out….

POOF!

XXXXXXXXXXXX

Tezuka was petrified to see an unconscious mermaid lying in the clubroom, a very beautiful mermaid indeed with a honey brown long hair, similar to Fuji's. He looked around to search for Fuji only to find out that he was not around and it was only him and the unconscious mermaid were in the clubroom. And he was shocked as he looked at the body of the mermaid. She was wearing the uniform that Fuji was wearing before he disappeared out of sight.

Could it be…?
