Disclaimer: Neither Prince of Tennis nor Sailor Moon is mine.

Summary: It was a normal weekend practice for Seigaku regulars. That was, until a boy called Ryoma claimed himself as Tezuka's and Fuji's future son and told them that they were Sailors who were supposed to save future Seishun Kingdom! Sailor Moon background.

Seishun Moon

Chapter I: Prince of Crystal Tokyo

"Is it clear? We got to stay fit for the Kantou Regional Tournament. Yudan sezu ni ikou. Now, you're dismissed!"

As Tezuka's short speech ended, the Seishun Gakuen regulars prepared to leave. They were eager to enjoy their weekend that was started with an additional practice, regarding the upcoming tournament they had to face.

"Ah, there are them! Wait up, you guys!"

Eight heads turned to the source of voice's direction. They were greeted by the sight of a small boy, running fast towards them. A bundle of white fur—later known as a cat--was resting on his right shoulder, as if unaffected by its master's rage movement.

"Nya, that kid's sure running fast!"

"Who is he? Anyone's relative?"

The questioned boy eventually caught up with them. Panting hard, he bent on his knees for a while before collecting himself and straightened up.

The boy was not that small after all, only short and a little bit delicate. He was dressed in all white: jacket, sweatshirt, shorts and a pair of tennis shoes. Last but not least, a white cap was attached proudly on his head.

"Glad to at last find you. Come on Soldiers, we should get going as soon as possible."

Bewildered by the mysterious boy's words, Oishi asked, "I'm sorry, but who might you be? And what do you mean by 'soldiers'?"

Looking impatient, the boy answered hastily, "I'm Ryoma, the prince of Crystal Tokyo—sheesh, I bet you don't even know what Crystal Tokyo is, do ya?"

Eight shaking heads gave him his answer. The boy's once cocky expression turned exasperate for a split second, "Mada mada dane. Then I have to tell you the whole story, ne? Why don't we find some place to talk in peace, then?"

Incredulously, the regulars followed Ryoma to the 'place to talk in peace', which appeared to be their locker room. The boy in white settled himself on a bench next to the door while the others scattered around him in various pose.

"Wait!" Momoshiro suddenly cut in just after Ryoma opened his mouth to speak. "I just realize that whatever Crystal Tokyo is, it doesn't have anything to do with us, right? So why…"

"Nah, apparently you're wrong, Momo-jisan. It has everything to do with you," Ryoma said. All of the regulars were surprised.

"What does it have to do with--?"

"What is Crystal Tokyo exa--?"

"Momo-jisan?"

The stream of queries kept flowing.

"Saa, things are getting more interesting, ne, Tezuka?" The smiling tensai stated in amusement.

The captain apparently didn't think so.

"Minna-san," Tezuka's deep voice effectively shut the ruckus up. "If you want to know the details, I think Ryoma-san is here to explain and it's wiser to keep your questions to yourself for a while."

"Hai, buchou."

Ryoma looked up bemusedly to face Tezuka, who was standing next to the bench. "You really do have that authoritative aura ever since you're this young, eh? By the way, you can drop that formality, Otou-san."

The commotion exploded tenfold.

"Otou-san?!"

"Is that kid's Tezuka-buchou's…?"

"But he called me ji-san!"

"Ii data."

Too dazed to stop the vibrating noise, Tezuka was barely able to keep his stoic expression in tact. He just stared uncomprehendingly at Ryoma, who was smirking quite evilly.

"Saa, Tezuka, you have a child with another person? Ouch, I'm hurt…"

The comment was only loud enough for Tezuka to hear, but it was all it took to snap Tezuka back to reality. He glared at Fuji, but the tensai didn't seem the least bit perturbed.

"But he looks only two or three years younger than you are. How can he be your child? Or… perhaps you're an adult in disguise?" The fair-haired prodigy desperately tried to keep his laughter at bay. Real, Tezuka's expression was priceless.

"Fuji…"

"No wonder many people mistake you as an adult," Fuji hid a grin and maintained a hurt-puppy look. "After all this while, to think that you cheat on me…"

Shuusuke picked a really inappropriate time to reveal his sadism, Tezuka mused darkly. He felt a strong headache coming.

"You know what? He doesn't cheat on you," Ryoma interrupted suddenly, a mischievous glint sparkled in his eyes. "You're my mother after all."

The ruckus died down and pairs of eyes looked at Ryoma in shock. Apparently Ryoma didn't bother to keep his voice low. The eyes slowly traveled to the surprised tensai, then to the frustrated buchou, then back to the smirking Ryoma, as if they were watching an interesting threesome tennis match.

"Wha—"

"NYAAAH! Fujiko and Tezuka have a kid! A KIIIDD!!"

"Tezuka…" the fukubuchou looked dazed. "Fuji… you guys…"

"Minna-san, it's not like…"

"OISHIII!! I've told you that it's okay to spend Saturday night on bed! Even buchou did that!"

"Eiji!" Oishi snapped, blushing furiously.

"Oi Mamushi, look at yourself! You look all red!"

"Fusshuu… baka peach! I see you're an oji-san to a kid you don't even know whom!"

"What?!"

"Ii data, teheheheheh, ii data…"

"Minna-san!" Tezuka's voice once again silenced the ruckus. Heads turned to face their captain. Feeling his face heated up, the bespectacled boy continued, "I don't get what all of these are about, but I assure that Ryoma-san is NOT Fuji's and my son."

"Mou, I think he's cute enough to be our son," Fuji grinned mercilessly at the captain after he recovered from the shock, and received a death glare as a reward. He added hastily, "But I hope you all haven't forgotten that I am a guy."

"To tell the truth, we don't have that much of time…" Ryoma spoke. His eyes traveled to Kikumaru, Momoshiro and Kaidoh before continuing, "If you could stay still for a moment, I will tell you the story…"

A/N: A random idea of mine, hehe. Please note that I don't really know about Sailor Moon's details though, so half of what Ryoma would explain in the next chapter is from my imagination. See you next chapter!

Review please! Thank you for reading!
