Hi, this is EcstaticPetenshi! For those who've never read my stories before, nice to meet you. For those who knows me and are expecting this story, sorry for the wait. Anyhow, I hope all of you will enjoy this brand new story!

Thank you for those who've voted on my poll, I really appreciate it. It's so funny to find out that it ends with a draw: 6 votes for NiouxOC and 5+1 votes for ZaizenxOC. I decided to write this one first because Zaizen needs more love. (I hope he'll be also playable in the upcoming Dokisaba Love Passion DS just like Kenya.)

Disclaimer: The Prince of Tennis, its characters, and Shitenhouji don't belong to me. They're Konomi-sensei's. I only own the OCs here.

Sorry for grammar errors and typos.

Yamato Nadeshiko is a Cinderella

Ch1: Prologue - It All Start Here

"Naa, Tsubasa-chan, come with us this once."

It was a pleasing afternoon in Shitenhouji Junior High. The weather was so good, such a perfect day to leisure. That was what some of the 2nd grade boy students. They would prefer to hit on some girls and hang out rather than go to the club. They were, at the moment, trying to convince one of the most popular girls in class to go out with them.

"Sorry I can't. I still have club activities after this." The girl called Tsubasa replied.

"It's okay to skip the club once in a while right?" Said one of the boys.

The others nods. "Yeah, pretty please?"

Tsubasa sighed. These boys were really persistent, weren't they?

"C'mon, Tsubasa-chan…" One of them grabbed her hand.

"Wait, let g-"

"Let her go you insolent fools!" A girl yelled as she approached the group of 2nd graders.

"Crap! It's the sister complex!"

"Bad timing. Let's go."

"Later, Tsubasa-chan."

The boys walked away in fast pace leaving the sisters. It was too bad that they had to give up the chance to go out with Tsubasa, but the older girl, who had just yelled angrily at them, was really a pain in their ass. She never let any boy go out with her sister. That was why people called her a sister complex.

"Thank you, Tsubaki-neesan." Tsubasa hugged her sister who was only 1 year apart from her.

Both of the girls had almost identical face, they were sisters after all. The only differences were Tsubasa had longer hair and was taller than her sister. She was in fact taller than any girls at her age and looked like a model; this was one of the reasons why she was so popular among the boys.

Tsubaki frowned. "Geez, boys these days… They're just really stupid and perverted. Make sure that you won't become like them once you turn back into a boy."

"Yes, ma'am~" Tsubasa giggled hearing how her sister sounded like an old lady.

There was a reason why Tsubaki never let any boy approach her sister: Tsubasa was actually a boy.

The siblings Yamato Tsubaki and Yamato Tsubasa came from a very traditional family. To protect the only heir of the family from catastrophe, he should be raised as a girl until the age of fifteen. In other hand, the daughter of the family bore a special duty to protect her sister's secret.

Everything had been easy for Tsubaki until Tsubasa attended junior high. He became popular and started to attract the boys, this made him constantly hit by them. She just couldn't let these boys lay a finger on him.

It was not like she hated all boys, it was just most of the boys who liked to hit on girls were perverted and ill-mannered. She couldn't let her guard down, what if they did something bad to Tsubasa? It wouldn't only endanger his secret, but would also psychologically hurt him.

"Seems that you're thinking too much again, nee-san…" He said as he watched her frowning and drowning deep in her thought.

She looked at him and patted his head. "I just don't want something bad happened to you, after all you're my precious little brother."

"Just don't overdo yourself, okay? I am really happy that you're really concern about me though." He smiled.

She smiled back. His smile never failed to light her up. Perhaps this was also one of the reasons why everyone in school liked him so much.

"Ah, by the way, my class is going to swimming pool this weekend." He said sheepishly. "What should I do?"

"Swimming pool? That's a big NO! They'll easily find out that you're a boy with those swimming wear!" She snapped. "Damn those filthy boys, it must be their idea!"

"Calm down, nee-san. If you shout like that someone might hear our-"

Wondering why he stopped talking, she looked the direction he was looking at. She froze. Not far from where they were talking, there was a guy looking back at them with a face that was as surprised as the siblings'. It was obvious that he had overheard what she had just said.

She recognized him. Black hair, earrings and tennis bag, it was the infamous 2nd year punk Zaizen Hikaru.

Sorry for the very short chapter. I just wanna put the family background and how Tsubaki met Zaizen how.

About the OCs, the main character here is Tsubaki (obviously). Tsubasa will also have important role here though.

About the idea… There is already a lot of cross-dressing female OCs here so I try to make a cross-dressing male OC. The setting with traditional family that made the sons dressed as girls is quite common in mangas though (especially the shoujo ones) I'll try my best not to make this story typical and boring!

Hope you like this short chapter/prologue. Please review! ConCrits are always welcomed.
