Neo Stardust

100. Heart

Slifer Red Mark

Yusei was in the fight of his life; between a Signer and a Dark Signer. Blue flames surrounded the area; and he was staring down Cyber End Dragon with Stardust Dragon and Sonic Chick on his side of the field. To make matters worse, he turned to look to his left. Jaden, his friend from another time who got stranded in Yusei's in a freak accident, hopped into the duel before it started to help Yusei. Not that the fact that he wanted to help Yusei was a bad thing, no he appreciated it, but they were both down to 1200 Life Points because of his faults. Jaden apologized profusely for the wrong moves he made, but Yusei kept his hopes up that maybe Jaden would shine in the end, or he'd draw exactly what he needed to turn thing around, like many duels before. Yusei had one trap on the field, while Jaden had four cards in his hand, and Elemental Hero Neos on the field.

"I end my turn." The Dark Signer responded. Yusei could feel Jaden swallow as he put a hand to his deck. "A-Alright… my move…" He closed his eyes, not ready to look at what he was about to draw.

"Jaden." Yusei spoke softly, but sternly. Jaden nervously looked over t his duel partner as Yusei gently clenched a fist to show how strong he felt about what he was about to say. "I believe in you, and your deck. That's why I gave you that card."

"Here." Yusei stated, a white card in his hand. Jaden took it proudly, eyes wide at the name and power of the card. "A card like this actually exists?" he smiled up at Yusei. Yusei gave him a small smile and nod. "Since your deck is mainly Elemental Heroes, I figured it would have a good home with you."

"Wow, thanks, Yusei! This means a lot to me!" His eyes were practically sparkling with joy. He looked back at the card with one eyebrow raised. "But what card is 'Elemental Hero Neos Knight'…?"

Yusei shrugged. "Maybe in the future, we'll find out for ourselves."

"I'm already looking forward to it!" Jaden responded proudly.

Jaden's eyes reflected the exact opposite emotion; despair as his partner continued. "You may have made some wrong moves this duel, but believe in your Elemental Heroes, and they'll respond with all their might."

"Yusei, I…"

"Trust me."

Jaden looked back at his deck. He pulled the card he was about to draw proudly a few inches out of his deck, then finally drew it, eyes closed as he pulled it in front of him. He opened his eyes. "No way!"

Monster Reborn.

Yusei knew that it would be the card Jaden needed to summon the card he gave him. Jaden stared at the card in awe before turning to Yusei and smirking. "My cards are your cards, right?" Yusei nodded.

"Alright! I activate Yusei's facedown!"

The card flipped up, revealing an illustration upon it showing a mist coming from a graveyard.

"Call of the Haunted! It allows me to resurrect one monster from mine or Yusei's graveyards and I pick Yusei's Junk Synchron!"

The familiar little orange monster returned on the field in attack mode. "Then I play this! Monster Reborn!" Jaden cried, flashing the spell straight from his hand. "And the monster I resurrect is…! Elemental Hero Clayman!" A brown ball-like monster appeared in defense mode; turning a blue tint once he posed in his defense stance.

"And now! Time for something…" He scratched his cheek and chuckled, "New for someone like myself! Synchro Summoning!"

The Dark Signer's eyes widened, while Yusei flashed a slight smile.

"I tune Junk Synchron with Sonic Chick and Clayman!"

That smile didn't last for long as Yusei's mark went from just glowing, to throbbing. But what caught Yusei off guard was, it wasn't like before. It was more of a...heart beat. Like his heart was beating rapidly fast in his arm. "Wha-…?"

Yusei didn't get to watch the Synchro Summon's beauty as a light soon slammed into Jaden's side of the field. Yusei looked up just in time as it began revealing a bulky dragon wearing an armored mask of blue with a gold rim. It had a green crystal cut like a diamond right between it's eyes on the mask, it's eyes the same green. The dragon was a pure white and it's wings had a few red areas amongst all of the white, and it's tail ended with the same red tip. In the center of it's chest lay a circular gem of sky blue, and it's orange mane whipped around as it roared. This was the card Yusei had given him; Elemental Hero Neos Knight's Dragon.

But as Jaden was about to call out it's name, he stopped mid sentence, clenching his right arm. "N-Naa…! What's with this pai-Nnnaaauuuugh!" The Slifer cried as he lifted his sleeve up, revealing to Yusei a red light practically inscribing itself on Jaden's arm as he cried in pain. Yusei looked up at the dragon Jaden had called fourth as it let out a slight growl. "He called fourth…his Signer Dragon…" He thought, blaming himself for Jaden's misery. He looked back and saw the mark finish its duty of marking its holder. Three orbs were seen upon the mark, and it had a pointed end to it, with a line meeting the end. Jaden finally stopped screaming once this act was done and fell to his knees, gasping as he held the mark. "Jaden!" Yusei shouted, "Are you alright?"

Jaden looked down at his mark. "Y-Yusei…What is this…?" He said, holding his arm up high, "It's got a heartbeat!"

Yusei had a jolt go through his entire body, and a beat resound in his own heart as it became clear that Jaden was experiencing the same feeling of a heart in his mark as did his. "Focus on attacking, Jaden!" He cried out, "I'll explain once we get out of this!"

"A-Alright…!" Jaden locked eyes with the signer. "I activate Neos Knight's Dragon's special ability! By discarding my entire hand, two of our monsters can attack your Cyber End Dragon together with both of their Attack Points combined!" He put three cards into the Graveyard as required."What?"

"And I choose Yusei's Stardust Dragon!" At Jaden's declaration, their marks seemed to beat faster. Yusei gripped his mark in worry. "Better speed this up!" Jaden pointed at Cyber End Dragon. "With 5000 Attack Points, your Cyber End Dragon is going down! Neos Knight's Dragon! Attack with Righteous Flare!"

"Stardust Dragon! Reverberate! Shooting Sonic!"

With a blue and red blast from Stardust and Neos Knight's Dragon, Cyber End Dragon was destroyed with a bang, and the Dark Signer sent flying into the flames as his Life Points hit zero. He fell to the floor and the flames went out. Yusei sighed, letting the Dark Signer lie there. He wouldn't remember anything anyway. He was more focused on Jaden, who was just now standing up, looking rather surprised. He was gripping the arm with his mark, speechless as well. They both took care of their cards and put them back in their decks. Yusei then made his way over to his partner. "You did great, Jaden."

"Th-Thanks, but…What does this mean…?" He said, looking down at his mark.

"You're a Signer, Jaden. What I explained earlier to you?"

"Me…? A Signer…?" Yusei nodded, taking the time to look at Jaden's mark. Jaden cringed in pain, but Yusei knew his, although giving him some pain on top of it, was still throbbing with a heartbeat; for his mark was still doing the same. Yusei wasn't of average intelligence; Yusei used proper reasoning to conclude that from the shape and three sections at the top, this was the Heart Mark of the Dragon. Once Yusei concluded this, the mark vanished. "H-Hey! Where'd it go?" Jaden asked, confused out of his skull by now. Yusei felt his mark stop giving a response as well. He let Jaden's arm go. "Treasure the disappearance while you can. After a good few responses, it'll be engraved into your arm."

"Yie…" Jaden cringed, not enjoying that concept. Yusei, however, smiled slightly. "I don't know exactly what to make of this. You're the fifth Signer, Jaden. We've been looking for you for quite some time now."

"Me…?" He pointed at himself, Yusei nodded.

"We need you. And as a Signer, you're bound to have a bond with me, and the other Signers." "Sweet!" Jaden automatically cried out, not taking the pain into his mind, but the fact that he was bonded to Yusei. Then, he covered his mouth as that came back to his mind. Yusei's smile faded. "However. You will have to duel one of those Dark Signers again. And you have a responsibility with the rest of the Signers to save the world." Jaden shrugged.

"Yeah, so what else is new in the live of Jaden Yuki?" He chuckled, but Yusei knew this wasn't a laughing matter. Yusei stood there for a few seconds, then walked back to his trusty motorcycle, Yusei Go. Once a silence was shared between them, Jaden broke it. "So, uh…what kind of mark do I have anyway?"

"The Heart. I have the Tail." Yusei put his helmet on, "Fitting. You're the most lovable person I've ever met." He smiled a little, and this made Jaden blush. Standing there in complete shock, he nearly didn't catch his helmet which Yusei threw at him.

A/N: Okay, so maybe some of these won't be drabble-sized. lololol Yeah; I decided that if Jaden was ever a Signer, he'd have the Heart. Cause he's a very lovable kid, yaknow? x3 Also, this takes place before Bonds Beyond Time, obviously, and before Leo was proven to have the Heart, so we avoid any paradoxes caused. xD So don't tell me Leo has the Heart. I know. Sheesh.

Also, I'd like to thank my cards for helping me act out the duel; Hyozanryu, Sonic Chick, Peacock, Blue-Winged Crown, Malefic Red Eyes, Call of the Haunted, Cyber Laser Dragon, Stardust Xiaolong, Cyber End Dragon, Malefic Red Eyes again, V-Tiger Jet, Malefic Blue Eyes, and Water Dragon! x33 I believe in Duel Spirits and the Heart of the Cards, so I kinda have to thank them. Lol I'm such a wimp.

Anyway, till next time,

-Ana
