Author's Note: Just a little something that came into my mind when I was re-reading the manga. I always liked the idea of Ryoma having an older sister, and I imagined their relationship, and then I came up with this. I'm not entirely sure if I want to make this more than a oneshot. Tell me what you think, please?

The sun was blaring down upon the tennis courts of Seishun Gakuen, where Kikumaru Eiji and Echizen Ryoma were playing a practice match.

"Nee, Echizen, you getting tired already?" Eiji taunted as Ryoma prepared to serve.

Ryoma glared at him and smirked, "aren't you?"

Sweat trickled down their faces and they were breathing heavily.

Eiji smiled as they continued their practice match.

Inui had suggested it, saying that the game would be beneficial to both, and whoever lost would have to drink his special veggie juice. The two were down to the last point of the intense match, which was a tie-breaker. No one wanted to drink the damned veggie juice.

It was extremely hot, which made the game all the more harder.

Ryoma served, a slice, which Eiji quickly returned. When Ryoma was about to hit the ball, however, he was distracted and accidentally hit the ball feebly, hitting the net.

"Ochibi! You lose!" Eiji said, jumping for joy. No veggie juice for him.

Ryoma muttered a curse as a woman entered the courts.

She was dressed in a cocktail dress and heels, her hair was tied into a high ponytail and her face was made up. She struck Eiji as someone who looked very much familiar.

Then it hit him. She looked a lot like Echizen. Her hair had the same green streaks in the light, her eyes had the same feline qualities as Echizen, even the same color. Her skin was as fair as his, and she was taller than him by just a couple of inches, plus some because of the heels.

This was either Echizen's extremely young looking mother, or his sister.

She walked quickly up to Ryoma, a bit awkwardly, as she came closer, Ryoma gulped, but didn't move from his position.

Coach Ryuzaki did nothing to stop the woman, although everyone expected her to. Even Tezuka didn't, probably because it seemed okay with the coach.

She raised her fist, and to everybody's shock, she punched Ryoma square in the jaw.

He landed on the floor, his hand on his jaw.

"I've been waiting to do that for months!" She said as she took a step back, shaking her hand, as if it hurt to punch Ryoma.

"That was uncalled for," Ryoma said as he stood up, dusting himself off.

"And leaving your sister in the middle of the Nevada desert is called for?" She shouted, moving towards him again.

Everyone had stopped what they were doing, their jaws open with shock as they watched the scene between the siblings unfold.

"It was," Ryoma shrugged as if it was nothing.

"You little punk!" The woman shouted getting ready to punch him again.

Just then, another woman entered, wearing a sports suit, running to Ryoma's sister and grabbing her by the waist before she could do it. Ryoma had moved away when she had attempted to kick him from her restrained position.

"Let me go, Rei!" she snarled at the woman who was restraining her.

"Lina!" The woman shouted, "you're causing a scene!"

She pointed an accusing finger at Ryoma, who was now being cared for by his senpai, Oishi, carrying a first aid kit.

"That bastard left me alone in middle of nowhere!"

At the sidelines, Eiji joined Momoshiro and Fuji, and the taller man whispered, "sounds like something Echizen would really do."

"Sounds like it," Fuji nodded.

"Hey," Ryoma said, his usual nonchalant self, "you got out didn't you?"

Lina gritted her teeth and glared at him, still straining against the hold that the other woman had on her.

"Lina, you'll be late for your interview," Rei said in an attempt to diffuse the situation.

After a few moments, Lina had calmed down, but her eyes didn't leave Ryoma, nor did she stop glaring at him. Rei slowly released her, and Lina quickly went to Coach Ryuzaki.

"I apologize for this little incident," she said, bowing, "family matters are not to be brought into the tennis court."

She stood upright and walked towards the exit, passing Momoshiro, Eiji and Fuji, who all moved out of her way.

"Inteview for what?" Ryoma asked, very much intrigued.

Lina turned, Rei beside her, with a smirk, she said, "I'm enrolling into Seishun Gakuen, otouto-kun."

Ryoma visibly paled.

"Shit," he muttered under his breath.
