Disclaimer: I do not own Card Captor Sakura

RainForever Note: Gomen! It has just came to my attention (thanks to IamTheBattleMaiden) that I accidentally had Syaoran say they were 17 in chapter 3. They are only 15 in this! Please just ignore that. And again, Gomen! Hope you enjoy!

Chapter Four

Sakura's eyes widened slightly, "A-a rival!?" she managed to spit out.

Syaoran folded her arms, "I highly doubt this 'rival' would be of any threat, seeing as the cards have been seal for five years now. How could this person possibly think they would be able to get them from Sakura?" he questioned with a sigh of relief.

"Don't be so quick to jump to conclusions, kid. Eriol wouldn't have bothered telling me about this person if they were not a threat. I'm not saying they're a big one, but definitely a threat." Kero stated, his arms crossed as he floated in the air.

"But Kero, Syaoran does have a point. Even though I'd love for there to be something new for me to tape, I do have to wonder how this person can be considered Sakura's rival." Tomoyo said, placing her video camera down onto Sakura's bed.

Kero sighed, sitting on top of Sakura's dresser, he looked directly into Syaoran's eyes, knowing Sakura wouldn't know about what he was about to say, "Have you ever heard of the Shadow Cards?"

Syaoran nodded slightly, "It was a myth passed down my family. It's suppose to be another set of clow cards, slightly altered and slightly weaker. Shadow Cards were said to have some cards that the Clow Cards don't, but also that the Shadow Cards don't have all the ones the Clow Cards have."

Kero nodded in agreement, "It was also said that once the Clow Cards were changed to Star Cards, the person destined to have possession of Shadow Cards would suddenly gain all the knowledge they needed, and the cards would already be sealed under their power. We, Yue and I, didn't know wether or not it was true, seeing as this is the first time the cards have actually been changed into Star Cards. But it turns out, that it is in fact true."

Sakura fell onto her bed. "Shadow Cards?" she whispered, half to herself.

Syaoran looked to Sakura, "The Shadow Cards were created to help their owner protect the Star Cards and their owner," he turned back to face Kero, "So I don't understand how this person could be a threat."

Kero sighed, "That's exactly it. Although they were created to protect the Star Cards, they do not influence their owner."

"Meaning the owner is the one who decides whether or not they want to protect them?" Sakura interrupted, sitting up.

Kero nodded, looking from Sakura, to Tomoyo then back to Syaoran. Kero knew that Syaoran had a good understanding of what he was talking about, so he thought it would be best if he were to mostly speak to him about it and let the others listen.

Syaoran brought his hand to his chin, rubbing it as he thought, "So this person, what do they want? And besides, the Shadow Cards aren't as strong as the Star Cards, you said so yourself. So why would this person even bother trying anything?"

"Eriol is unsure of what this person wants, nor who the person even is. And yes, the Shadow Cards are believed to be slightly weaker than the Star Cards. However, it probably also depends on the magical capabilities of their wielder. And even though there is a high chance that the Shadow Cards are weaker, you also have to take into account what other cards they might possess." Kero stated, looking to Sakura, "So I guess what I'm trying to say is that you should definitely keep your guard up at all times, Sakura."

Sakura nodded, seeing a flash in the corner of her eye. She turned her head to see that Tomoyo had once again picked up her camera and started filming. The little red button turned off and Tomoyo lowered it from her face.

"How exciting! A brand new adventure! I think I'll go buy some more film after school tomorrow." Tomoyo said excitedly, not even a little worried about her friend. She noticed the confused look she was getting from Sakura, "You'll be fine. You've gotten a lot stronger, Sakura. You shouldn't worry too much. Just keep your guard up like Kero said," she leaned into Sakura's ear and whispered the last part, giving her a small nudge, "And you have Syaoran here to help you too."

Sakura's face instantly went red, and she jumped up from her bed. "Well that explains what happened this morning. The reason I felt the presence of a clow card." she said softly, her red face slowly going back to normal.

Syaoran looked to Sakura, "Since this is vacation for me, and I don't need to go to school with you guys, I'll see if I can find anything or anyone."

Kero nodded, "That's probably a good idea. But be careful, kid. Eventhough the Shadow Cards aren't quite as strong as the Star Cards, they are still a lot more powerful then the elemental papers you use with your sword." Syaoran nodded.

Sakura thought for a moment, suddenly noticing one of the details that Syaoran had said, "Wait! A vacation? You mean, you're not staying? How long are you here for?"

Syaoran quickly turned to Sakura, "No, I'm not staying. I'm leaving a week from today."

Sakura's face fell, "Oh." was all she managed to say.

'Poor Sakura. She passed out before Syaoran could tell her. She must have thought he was moving back.' Tomoyo thought, draping her arms around Sakura's shoulders.

"Cheer up Sakura!" she whispered into her ear, "You have a whole week to spend with him. Just make the best of it."

Sakura smiled, nodding. "Right!"

Syaoran just gave Sakura and Tomoyo a blank stare, and then his eyes darted to the window, followed by Sakura's.

"I sense something." Sakura and Syaoran said in unision.
