A/N: This is another collab with Shadgirl2! For those of you who read Fiend's Servant, the sequel will start soon, don't worry! Probably by the end of the week, I'll have the first chapter up. Anyway, enjoy! We don't own Yugioh GX, the plot is Shadgirl2's, and so is Kathleen.

Flashbacks are in bold.

WARNING: OCs

Edit: Animallover pointed out a typo in the chapter, so it's been changed accordingly. Thanks for drawing my attention to it!

"Ah, class reunions! I love them! Especially this one!" Cronos chirped as he walked through the crowd of his former students.

It was the five year reunion for the group that had brought all sorts of chaos when they had enrolled—and he was eager to see all his favorite students again and see how they were doing. Manjoume, Asuka, Sho, and, of course, that drop-out boy.

But his favorite student never showed up.

"So, remind me again why you guys are all here?" Asuka asked O'Brien, Jim, and Johan, who were here for inexplicable reasons. "Don't you have your own reunions to attend?"

Really, it was graduation all over again, and Jim was in on it, too, this time. Why were they at the Japanese Duel Academy reunion when they had only been students here for half a year? Heck, how had they even found out about it?

"Well, we wanted to see you guys!" Johan said.

"Besides, our reunions were on different days," Jim added.

"Well, mine was today, but I don't care," O'Brien admitted.

Asuka looked at the other people whose excuses were unknown to her—Ed Phoenix, Ryo Marufuji, Rei Saotome, and Tyranno Kenzan. Honestly, she was starting to wonder if her brother wasn't hiding out here somewhere, too.

"And what about the rest of you?" she asked them. "You're not even in our class."

"Let's just say, I have my reasons," Ed said, eying Manjoume.

Ryo nodded in agreement.

"I'm with Ed!" Rei said, as if that explained everything.

"Well, honestly, I was hoping Aniki would show up," Kenzan said. "But..." He looked across the room to where Sho, Manjoume, Momoe, and Junko were talking.

"He's dead. I know it!" Sho said. He was, of course, referring to the guy who had yet to show.

"Now, now," Junko reassured him. "I'm sure he's on his way."

"I doubt it," Manjoume said, playing devil's advocate. "I think Sho's right, guys."

"WHAT!?" Sho screamed, earning the attention of everyone in the room...and probably in China, too. "WHY!?"

"What's wrong!?" Asuka asked, running over. "Is everything okay!?"

They all gathered around their panicked friend.

"ANIKI'S DEAD!" Sho paraphrased.

"What!?" the others demanded. Well, except for Manjoume, Momoe, and Junko.

Manjoume rolled his eyes. "Sho! I said he might be dead! See, I called him about a month ago, wanting to duel..."

Manjoume waited impatiently for the idiot to answer his phone. When he finally picked up, Manjoume got right down to business.

"Okay, you idiot!" he said. "I just upgraded my deck! It's ten times better now! Why, thanks to it, I'm the world champ!"

"Hey, that's great!" Judai congratulated. "So, I'm guessing you want to duel again?"

"Well, I can't exactly call myself the world champ if I don't beat you, now can I?"

Judai laughed. "Okay, sure! Any time, Manjoume!"

"Good! Then I'll see you in—"

There was some noise in the background. "Hold on, Manjoume!" Judai said. A moment of silence followed before, "Oh, crap."

"What?" Manjoume asked. "What is it?"

"I gotta go, I'll call you later, 'kay?" Judai said urgently.

"Wait! What's going on!?"

He never got an answer—Judai hung up before the words had even left his mouth.

"And, after that, he hung up," Manjoume finished. "That was a month ago. I've been trying to reach him ever since, but he never picks up."

Sho was quiet a moment before saying, "He's dead... I knew it..."

Kenzan lowered his head. "Well, that's a real bummer..."

Shoulders hunched, he started walking off.

"Where are you going, Kenzan?" Asuka asked.

"To drown my sorrows in old memories..." he said as he left.

"Come on," Johan said. "That can't be true, can it? He's not the kinda guy who'd just keel over and die! He has te be alive! He just has to!"

"I'm not saying he isn't," Manjoume said. "I'm just saying it's possible. Heck, knowing him, he may have just decided not to come."

"Yeah. That makes me feel much better, Manjoume," Asuka said sarcastically.

"Let's all just calm down," Jim said. "I think it's more likely he's late, or he forgot the date or something. Heck, I doubt different time zones are something he really understands."

"No. He's dead... Just like Superman's dead... No hero ever lives for long..." Geez, Sho could sure be a pessimist.

"Sho..."

Kenzan came running back in, saying, "Guys! Guys! Take a look at what I just caught!"

Fishing pole in hand, he'd clearly been fishing, so Ed made the logical guess. "What? A fish?"

"No! A bottle!"

"Oh, yeah. That's so much cooler than a fish," Manjoume retorted, crossing his arms.

"It is when it's got a note!" Kenzan said.

"What?" Ryo asked.

Kenzan held out the note, and Jim took it and read it aloud: "To whoever finds this, I'm stranded under the sea. A crazy man brought me here and won't let me go. So, if anyone actually sees this not, then please send me a rescue party! P.S. I'm not entirely sure where I am, but I think it's near the coral reef seeing as how there's a lot of coral just outside."

They all stared at the note for a moment, not sure what to make of it. For one thing, the writer clearly thought there was only one coral wreath, so...well, yeah. Unless it meant the Great Barrier Reef...and even that wasn't much to go on. Clearly whoever it was wasn't the sharpest tool in the tool shed.

Finally, Ryo asked, "What is that?"

Jim tipped his hat, letting out a low whistle. "Sounds like someone's in a tight spot."

"Sounds like a prank to me," Ed said. "How do you get stranded under the sea?"

Rei looked sympathetic. "I feel sorry for them. Wish we could help."

"Well, maybe we can!" Johan said, a brilliant idea coming to him.

Everyone stared at him, making him wonder if he'd been speaking Danish or something.

Jim was the first to recover. "You lost me, mate. Could you back up a bit?"

"It's simple," Johan told them. "Someone's in danger, we found their note, we just so happen to be heroes, so why don't we try to find them?"

"Uh, news flash!" Asuka said. "I'm no hero, I'm a teacher! And it just so happens to be the middle of the school year, so I think I'll pass."

"Well, Johan's right," Rei said. "We have to do something..."

"I say we call the police," Manjoume suggested.

"No. The clue isn't specific enough for them," Asuka reasoned. "Maybe the FBI though..."

"It's doubtful that we could find this person, anyway, Johan," O'Brien reasoned. "There's too little information. Do you have any idea how much of the world is water?"

"But they must be feeling horrible down there all alone," Sho countered, his mind off of Judai for the moment. "I say we should at least try to help!"

"I agree with Marufuji-senpai!" Kenzan said.

"Guys, I understand how you feel, but O'Brien's right," Ryo pointed out. "The ocean's filled with coral, so this place could be anywhere."

"I'm with you, Kaiser," Ed said. "Besides, I still think it's just a joke."

Johan wasn't happy with how his suggestion was being taken. "Aw, come on, guys! This could be our chance to embark on another exciting adventure together! Doesn't that get you all fired up, just thinking about it!?"

"Well, considering how our last 'adventure' went, not really," O'Brien answered, thinking of those alternate dimensions.

"Aw, come on, mate!" Jim said. "It could be fun!"

"Yeah!" Fubuki said, popping out of nowhere as he so often did. "I mean, it's not like we're going to Dark World again! Come on, guys, try and picture it! Us, sailing the great blue wonder, fighting off pirates and sea monsters. Hey! Maybe we could even sing sailing songs!"

"Nii-san!" Asuka protested as she tried to figure out where he had come from and what he was doing here in the first place.

"Am I the only one here that thinks there's something fishy about that note?" Ed asked.

Kenzan was about to make a comment about it having been in the ocean, so of course it was "fishy," but Manjoume spoke up first and spared them of that pun.

"With all the weird crap that's always happening at this school?" he asked, a lame look on his face. "Yes."

"Come on, guys!" Johan encouraged. "Think of how that poor guy feels. Would you be happy if you were stranded at sea and no one tried to find you? Well, I don't know about the rest of you, but I'm gonna see what I can do to help."

"Count me in, mate!" Jim said.

"Alright," O'Brien relented.

"Yeah!" Sho and Kenzan cheered in unison.

"I guess it couldn't hurt," Asuka admitted.

Manjoume humphed. "Whatever. It's not like I've got anything better to do anyway."

"I'm in," Ryo said.

Fubuki pumped his fist in the air. "Alright! Our next grand adventure begins today!"

"I'll go, too!" Rei chimed in.

"Great! So, does that mean everyone's in, then?" Johan asked, glancing at Ed.

"I guess," he said, shrugging.

"Awesome!" Johan pumped his fist in the air. "Then let's go, guys! Off to our new adventure!"

Hayato walked over. "Hey, what's going on, guys?" he asked.

"We're going on a sea adventure to save a guy who's stranded!" Johan summed up.

Sho asked, "Wanna come along, Hayato?"

That was random and out of the blue, but he wasn't going to pass up on a chance to hang out with his friends, so he said, "Okay, sure!"

"Great. But, first, we should try to get a better idea of where this person is," O'Brien said.

O'Brien hacked into a government satellite to find some maps of the ocean floor. The results—way too much of the sea floor had coral wreaths, as they had feared.

"Crikey," Jim whispered. "I think this bloke just might be out of luck."

Johan took a walk down to the beach to clear his head and try to think of something. After all, if he didn't come up with some way to narrow their search area, this adventure would be over before it even began.

He got to the beach to see a woman with long, wavy, red hair in a blue one-piece swimsuit and flippers. And she was...talking to dolphins.

"Hmm. That's so not good," she said. "Are you sure?"

Johan stared at her in confusion. "Huh?"

Surely his eyes were playing tricks on him. He watched for a moment, listening to the dolphins whistle.

"Oh, the poor thing!" she said when the dolphin was quiet. "Where did you see this?"

Is she...nah, I've gotta be imagining it.

He rubbed his eyes, trying to clear them. It didn't help—she was still talking to dolphins.

"What!? Behind me?" she asked in response to more whistling. She turned, red eyes landing on Johan. "Uh, can I help you?" she asked.

Johan wasn't sure he wanted to know, but... "Are you...talking to a dolphin?"

"Yes," she said.

"Oh."

"I know what you're thinking. I must be crazy, right?"

"No, I—"

"Well, that's so not the case," the woman interrupted. "See, I've got this gift that lets me hear the voices of animals, so I can actually talk to them. But I really don't have time for this right now. Crystal here said she saw something that I just gotta look into."

Curious, Johan asked, "What's that?"

"Well, see, apparently she saw a building in a 'bubble' full of kids and 'strange green plants.' But what's bothering me is she said she saw a man being led across the place by another man with his hands 'hooked' behind his back."

"What!? Where at!?" Johan asked, certain that had to be the same person who had written the note. After all, how many people could be being held prisoner underwater?

"Don't know," the woman said. "That's what I was about to find out."

"Well, don't let me stop you!" Johan said, waving for her to continue.

The woman turned back to the dolphin and said, "Right, you were saying?"

The dolphin whistled, answering her.

"Uh-huh...I see... Okay!" she turned back to Johan and said, "Somewhere in the middle of the Pacific, close to the equator."

Johan, not even caring that this still left them with a wide search area, was ready to run off as he said, "Thanks!"

"Wait, where are you going?" the woman asked.

"My friend found a bottle with a note saying someone was being held against their will under the sea, and we were gonna go help them, so that info's really helpful, 'cause the note didn't say anything except that there was a lot of coral," Johan said quickly.

"Really!?"

"Uh-huh!"

"Then count me in, too!" she said. "There's no way I'm gonna abandon someone in need! But, wait. Who are you again?"

"Oops," Johan said, realizing he hadn't introduced himself. "I'm Johan! Johan Andersen!"

"I'm Kathleen Summers," the woman said. "I take it you're here for the big event? Me, too! Although I was only here for one year." She giggled, rubbing the back of her head.

"Same here!" Johan said. He scratched his cheek sheepishly as he amended, "Actually, less."

"Really!? That's so cool!"

They had a very off-topic discussion about their adventures here, during which Kathleen mentioned something about a Society of Light and Johan told her about the Des Duels and alternate dimensions and Yubel and even Darkness. It took them awhile to get back on track.

"Well, anyway, we should probably get going," Kathleen admitted. "You know, guy being held prisoner under the sea?"

"Oh, right! Let's go, come on!"

Kathleen told him she wanted to get dressed first, unless he was planning on scuba diving to find this guy. He told her where to meet up with him and his friends, and they split up for the time being.

He waited for her outside of the computer lab, where he could hear his friends debating the hopelessness of the situation. With that going on, he thought it would be best if he waited for Kathleen before going back in there.

She came over wearing a yellow tank top with a sea turtle decoration, white shorts, and tennis shoes. The shirt showed her midriff, and she had also put a white, pink, and yellow butterfly pin in her hair—at least, Johan assumed it was a pin.

"Ready?" he asked before heading into the lab.

His friends stopped and looked at him.

"So, guys?" he asked. "What do you think?"

"I think finding this bloke will be like finding a needle in a haystack," Jim admitted.

"Too bad," Sho said. "So, now what do we do?"

"Nothing," Manjoume said simply. "There's nothing we can do. Too bad for that fool, but I doubt anyone could find him now."

"You're wrong!" Kathleen said. "My friend Crystal's already found him! The hard part is finding a sub..."

Everyone but Johan stared at her, not sure what to make of this strange woman.

"Er, I'm sorry, sheila, but who are you?" Jim asked.

"Whoops!" she said. "My bad! Call me Kathleen! Nice to meet you all! So, about this kidnapping..."

"Johan. What's she doing here?" Asuka asked, sweating.

"Well, duh! I'm here to help! You think I'm gonna abandon someone in need? Heck, no!"

"Uh... Well, good to have you?" Sho said uncertainly. Why does this woman seem familiar?

"So, sub. We need one," she said, getting them back on track. "Any ideas?"

Sho looked at Manjoume.

"What?" Manjoume asked.

"Well?" Johan prodded. "Do you have one, Manjoume? 'Cause, obviously, the Marufujis don't!"

Manjoume humphed, then said, "I'll see what I can do..."

Startled, Ed said, "Wait. You actually have one of those? What for?"

"Why not?" Manjoume countered with a shrug.

"Then I guess that problem's solved!" Kathleen said. "Now all that's left is telling Crystal where to meet us, and she'll take us there!"

"Who's Crystal?" Sho asked.

"My friend," Kathleen said airily. "So, where to?" she asked Manjoume.

"Well, if we need a submarine, we'd have to ask my brothers to borrow theirs." Muttering, he added, "This should be fun..."

With no other alternative, the gang made their arrangements—for Asuka, canceling her classes for now; for Kathleen, telling Crystal where to meet them; and for others, rescheduling flights or sending pilots home—and boarded Manjoume's private jet, ready to take off for their next adventure.
