Duel Disks and Keyblades

Chapter Thirty-Five: The Other Promise

Yugi felt incredibly sore and confused. The last thing he had remembered was that Cid person yelling out that they were about to make an emergency landing. As the duelist pulled open his eyelids, the first thing he made to do was check to see if the Millennium Puzzle was still safe.

I'm here, Yami groaned. Just a bit shaken from the landing.

Nodding, Yugi stood up, brushing himself off. Where are we?

The sun in the sky had fallen into a state of dusk, and they had somehow managed to land in some back alley between several buildings. Nearby was a fence closing off a part of the alley, and the door in it was wide open. From his current position, however, Yugi couldn't make out much beyond it.

We're not in Domino City anymore, Yami replied. Sora should know where we are.

"Looks like you could use some help."

Yugi turned around to see an odd stranger standing behind him. The chubby boy was only a bit taller than he was, wearing a pair of jeans, a red shirt printed with the words "Dog Street" (whatever that meant), a black bandanna which kept up some very unruly black hair, and a pair of sneakers. The stranger seemed like a cheerful enough person to Yugi, but the duelist could feel Yami staring at him in doubt. Yugi nodded. "Yeah," He began slowly. "Do you know someone named Sora?"

The boy nodded. "Yeah. He got here not long ago and said he was looking for you. You a friend of his?"

"Yeah," Yugi replied. "Where is he?"

"Right over there," the boy said, pointing down the alley past the fence. "He's in the usual spot. Follow me."

Yugi did. They ended up in a small room of sorts at the end of the small alley. There were several couches, a dart board, and a few posters (written in an alphabet Yugi didn't understand). There was also a small wooden nightstand in the corner. Sitting on the electric heater was a rather miffed-looking boy with camo-patterned pants, a black shirt and vest, and blonde hair that somehow strongly reminded him of Jounouchi. On the couch was a girl with an orange shirt, yellow pants, and long brown hair. Next to her was none other than…

The raven-haired boy waved. "Sora, I found him!"

Sora smiled wearily. "Thanks, Pence." He turned to the others. "Guys, this is Yugi Mutou. I met him in Domino City."

The girl sitting next to Sora smiled. "Hi, Yugi. My name's Olette."

I like her, Yami noted, grinning. She seems nice.

The blonde-haired boy sitting on the heater gave him a suspicious look, narrowing his eyes. "Hayner," he said in a half-grumble. "Nice to meet you."

But I don't like him.

Be nice, Yami.

"And I'm Pence!" The boy standing next to Yugi said, offering his hand for a handshake. Yugi declined, but Pence was (thankfully) not offended.

"We're in a place called Twilight Town," Sora explained. "I know this is breaking the rules, but there wasn't much of a choice left."

Yugi felt his shoulders droop. "Will everyone be okay?" He muttered.

"They'll be fine," Sora replied. "Axel can take on hoards of Dusks. Shadows shouldn't be a problem. Besides, Jounouchi is a pretty good fighter himself. They're in good hands." Hayner seemed to twitch at the mention of Axel, but no one really paid attention.

While he knew that Sora was trying to cheer him up, Yugi still wasn't sure if he was right. Olette seemed to notice, and stood up from her position and rested a hand on the boy's shoulder. "It'll be fine," she said in a motherly tone of voice. "Sora's gone through this plenty of times before. He knows what he's doing."

"Yeah," Hayner added, "So quit sulking or I'll have to-"

"Hayner!"

"What?"

Yugi chuckled at the oddly affectionate display. "I guess you're right," he replied.

"Besides," Hayner continued, "After that whole mess with the other Twilight Town, I'm pretty sure everything will be fine. Organization XIII is gone, after all."

"Mostly," Sora corrected. "In Domino City, there's some sorcerer named Anubis making replicas of members of the Organization."

"Replicas?" Pence asked. "You mean like copies and stuff?"

Sora nodded. "Yeah. We've managed to get rid of them all, but now he's got an army of heartless attacking Domino City. Axel and Jounouchi should be able to hold them off, but in the meantime we need to think up of something to stop them…"

Yugi sighed. "My head hurts," he mumbled. "I know this is what we have to do, but…what if everyone gets hurt?"

There was an odd moment of silence before Sora stood up. "Let me show you something," he said, leading Yugi out of the Usual Spot.

Cid wasn't in the best of moods, but he still went about his business repairing the Gummi ship. After all, if Sora and that other kid were going to go back and patch things up, they were going to need some transportation.

"Hey, Cid! You there or not?"

The engineer rolled his eyes. "Yeah, I'm here Yuffie."

"It's about time. Squa…Leon and Cloud sent Stiltzkin to check on the situation in Domino City. So far, Anubis has been running all over the place trying to find the keyhole but he hasn't had any luck."

"Good," Cid replied. "How about the boys there?"

"You mean that red-head and the blonde? They're holding on their own fine, but they won't last forever."

"Anything we can do to help?"

"Stiltzkin said he met a man named Pegasus there. He sends a message: 'At last resort, use the secret card.' We're not sure what it means, but we think he directed it at Sora and Yugi."

Cid nodded. "I wouldn't doubt that. We all know about Sora, but that Yugi kid…he's something else…"

It's amazing up here, Yami commented.

Yugi couldn't help but agree. Sora had taken them up to the top of a clock tower, overlooking the entire city. The sunset was amazing, and the ocean beyond the town sparkled underneath it. There was an odd sense of peace that Yugi could feel here, and as Sora sat down, he thought he glimpsed Roxas sitting there as well, a far-away look in his eyes.

"This is Roxas's favorite spot," Sora told them. "But the others like coming here, too."

"It's a great view," Yugi pointed out. "I feel really at peace here."

"I do too," Sora replied. "It's kind of ironic because the keyhole is here, too."

"Keyhole?"

"Yeah." Sora gazed into the sky solemnly. "Every world has a heart, just like people do. Heartless go after that heart. When a person loses their heart, they become a heartless, and the shell they leave behind is their Nobody. A world is different. When that heart is drowned in darkness, it's completely destroyed."

The boy shifted, summoning the keyblade in his hand. "The keyblade isn't just a fancy weapon. It has the power to lock and unlock just about anything, from a lock on a door the keyhole of an entire world. I never got to seal the keyhole of my own home in time, and it ended up being destroyed. That's how this whole mess began…"

"Your world was completely destroyed?"

"Yeah…I managed to restore it though. Two years later, I don't know how, but I woke up here in Twilight Town, and Roxas was with me. I didn't get to meet him right off the bat, though…that happened way later. I'm not sure when I'll be able to go home, but no matter what happens, I have a responsibility to carry out, and I'm not going back until it's done."

Yugi couldn't help but sigh inwardly. Underneath that carefree, cheerful appearance, Sora still had his problems. Not only did he have a strong sense of justice when it came to what was right and wrong, but he even doubted himself at times. What stood out the most was his perseverance; a trait Yugi admired most. Sora knew what was right, and put it above what he wanted.

After a moment, Sora reached into a bag he had brought up to the top of the clocktower, pulling out two blue-and-white popsicles. "Here," he said casually, handing one to Yugi. "I got us some ice cream on the way here."

How come I didn't notice?

You were too busy looking at the rest of the city.

Oh…

Yugi warily accepted the popsicle, staring at it for a moment as though it were poisoned. After watching Sora eat it, Yugi carefully nibbled at the corner of it…

…and nearly choked in shock. "Holy-"

Sora laughed. "It's okay! Even I nearly choked on it the first time."

Sweet mother of Osiris, what kind of flavor is that?! Yami cried out, having tasted it the moment Yugi took a bite.

Yugi's eyes went incredibly wide. The ice cream tasted sweet as it should have, but at the same time managed to have a salty tang to it. This is amazing! He exclaimed. "What flavor is this, Sora?"

Sora beamed proudly. "It's called Sea-Salt Ice Cream," he explained. "It's one of the top flavors here. Axel doesn't like it much, though…"

"I think it tastes great," Yugi protested. "I'm not sure about Yami though…"

Yami promptly appeared next to Yugi, his arms folded defiantly. It's just different, that's all, he grumbled.

"Admit it," Sora teased. "You hate it, don't you?"

It's fine! The spirit insisted.

Yugi grinned mischievously. "You want some, Yami?"

I-I think I'll pass.

"Oh, come on! You said it tasted fine, didn't you?"

Yugi, if you think for even one second…

Sora and Yugi continued to tease Yami, and eventually clock tower rang, alerting them of the time that had passed. Yugi sighed, nibbling on more of his ice cream as he stared out at the eternal sunset. "I'm still not sure," he said, sighing. "After trying so hard to protect Domino City, things still come all the way to this. We had to run and leave everyone behind…"

Roxas appeared next to Sora, and both they and Yami were giving Yugi looks of concern. It wasn't long before the keyblade master spoke. "It's not over," he said, smiling weakly. "It's just not."

"How can you say that?" Yugi asked. "It's practically hopeless."

In response, Sora pulled out a concealed card from his pocket. The clear side of the card sleeve it was in was showed the back of the card instead of the front. "That Pegasus guy gave me this before we ran into Xigbar," he said. "He said only to use it as a last resort. It might be just what we need to get this over with, but before we go that far, I have another idea in mind that I'll show to you when we get there."

Yugi nodded. "I don't know what you've got in mind, Sora…but I trust you."

Sora grinned. "Right. Let's go."
