It took Group 1 the longest to unpack their bags, mainly because most of the boys were left wondering about what they just saw. Each one of the males had a question of their own.

Sora's was, "Who was that?"

Roxas and Terra's were, "What sort of fish were those?"

And Ventus had the most absurd one, mixed with the legends that surrounded Destiny Islands, "Could that have been a mermaid?"

No answers were known to them, but that wouldn't last forever.

When they finally lined up, one of the teachers Mr. Emans was the one who told them off for the amount of time taken. "You, Terra, as a prefect should have made your classmates' unpacking go at a quicker pace. Shouldn't you?"

"Yes, sir.." Terra nodded a bit, keeping his head down.

It was Riku who noticed a small smirk on the teacher's face, for a millisecond maybe but it was definitely seen by two students. One from Group 4 who never seemed to be noticed by anyone.

"But as you know, for your month here you are to do an assignment in your groups. Group 2 and Group 4 have already decided what they are going to do. Group 2, what is your objective?" Ms. Lockhart asked.

Shiki stepped forward - she was the most active when it came to the school paper so she could be considered...the leader, to coin a better term. "We are going to be investigating Destiny Islands' myths and legends and that will be the topic for this month's recap paper!" she answered, smiling in an enthusiastic manner.

Nodding slightly, Ms. Lockhart smiled a bit. "Very good...and what about you, Group 4?"

It was Tidus who stepped a foot forward. "Me, Wakka, Selphie, Seifer, Fuu and Rai are gonna interview some people on the island and record what it's like living on an island like this!" he mentioned, proudly.

The members of Group 1 went silent. They for one didn't have much of an idea about what their assignment was going to have, but luckily it didn't matter today.

"For those who do not have an idea for their assignments, please use the time you have exploring the islands to your advantage and see if you can think of an idea for what your project will involve. Now, as high school students at Crown Key we expect you will be able to behave appropriately when given the opportunity to explore the islands, especially since you shall all be representing the academy. Do I make myself clear...?" Ms. Farron questioned, looking at each one of the groups who simply nodded in reply.

"Good, now you have permission to go. And one more thing; please be safe - if anything you see can be considered suspicious, then please tell me, Ms. Farron, Mr. Highwind, Mr. Emans or Mr. Nasexm about it immediately." Ms. Lockhart finished off, smiling a bit.

With a gesture, the students began filing out of their...cabin, you could say, out to the outside.

A bright smile appeared on Sora's face once he took it all in. "See, Riku! It's just as good as I remember it." he told his best friend as he felt the light breeze fly gently through the air.

Riku looked around, eventually replying to Sora with, "Yeah, you're right." he nodded a bit to add slight emphasis.

"We should probably try to get an idea for this assignment today or we are not going to get by easily..." Roxas pointed out, looking out at the ocean.

Laughing nervously, Sora rubbed the back of his neck with a sheepish smile. "Yeah...we probably should. Hey! Me and Riku have been here a lot - we can show you some of the places here and maybe we can get an idea!"

"Sounds like a good idea; where do we start?" Ventus replied, smiling brightly. He was seeming pretty enthusiastic about this, like it was something new, even an adventure.

So that was what they did. Group 1 explored all around the main island, but soon enough Sora found himself looking out at a different island. He'd need to ask about that sometime.

Sora suddenly thought of an idea. "Hey, guys! How about we make it about structures, you know, like geography."

"Bravo, Sora. But sadly, Group 3 already have that idea in their brains, in fact; they're already working on it right now." Joshua said to them, dismissing their idea the moment they created it.

"Aw, great." Ventus sighed a bit, looking down.

"Still; we'll think of something, Ven." Terra reassured, looking at the boy, who smiled again and began looking around. That was when he saw something up ahead. It seemed to be a large rock with a strange design on it. Like a keyhole or something.

Things suddenly changed internally. His eyes were fixed on it, and he began walking towards it. Whether he intended to or not. Whether he wanted to or not. His hand reached out, a key like sword appearing in his hand. It had a black handle which was offset from the rest as opposed to being aligned with it with a guard just as misaligned as the handle. A dull gold in colour, it joined with the shaft which was gray, thin, and had a very slight curve outward with it being decorated with three thin dull gold lines that adorned it with the teeth being gray in colour like the blade and having a wing-like shape and a green gem for a keychain.

A bright light flew from it, almost making the blonde stumble a bit. By this time, Terra, Sora and Roxas turned around and ran over to him, only for the rock to fall flat and in the process, slowly roll out of the way.

"What did you do, Ventus...?" Roxas questioned, he was going to go in. The devil may care, but he wouldn't.

Snapping out of his funk, Ventus looked at the three and then gave his answer. "Oh...yeah. And I don't really know, this just showed up in my hand."

"Ven, you need to get rid of that." Terra's eyes went wide, not only carrying through on his duties as a prefect but another reason being he was worried about what this weapon could do. Not just to the students he was meant to discipline, but also to Ventus himself.

As Terra and Ventus spoke, Sora turned around and saw Roxas going in. To make sure his friend was safe, he followed after him. The inside of this cave was very pretty looking, with light blue crystals hanging from the roof that almost seemed to illuminate the hidden cavern. It was rather large and spacious, with rocks surrounding a deep pool of water that seemed to lead out to the sea, but it was hard to tell due to a large wall of stone that seemed to go into a bottomless pit. With a light breeze now entering the room from the rock being removed, being in there was quite...well, comforting, soothing. There was the sounds of rocks, gently being pushed into the watery abyss by their footsteps; followed by a light splashing...and talking?

Sora tilted his head. In the water was a girl...wait a moment! It was that same girl he had seen in the water while he was unpacking!

Alongside her was another girl who looked rather similar to the other girl. She had a similar structure to her and the same colour of eyes (that being blue), but she had hair as black as ink that went to about her neck in length. She had a bra made out of shells...and a black tail, the other girl having a pink one.

"Are those...?" Roxas mumbled, tilting his head. His blue eyes went wide from the shock.

"MERMAIDS...!?" Sora cried out, only for the two girls to turn around.

Roxas rolled his eyes at the brunette. "Well done," he muttered, sarcastically.

"Hey!" the girl said, looking over at them, her tail splashing in the water. "How did you get in here?"

The black-haired girl looked over at them. While the red-haired girl seemed confused but defensive, the girl with the dark hair just seemed shy towards them.

And Roxas would admit that she was quite cute looking, though he never was that type of boy, he truly couldn't help but think that about her.

Sora laughed nervously in response to the pink-tailed girl's question. "Yeah...that rock in front of it moved and we wanted to see what was in here." Sora then stopped laughing and cleared his throat. "We didn't mean to interrupt anything you might have been doing,"

Although the girl sighed, she did giggle a little bit soon afterwards. "It's fine, and to answer your question; congratulations, you guessed correctly." she said, showing her tail a bit and swimming around in the water playfully. "Oh! By the way, I'm Kairi."

"Um...Kairi?" the black haired mermaid said to her. "I don't think Naminé and Aqua will appreciate this,"

"Well...I suppose." Kairi muttered, starting to wish she hadn't said her name.

"Because we don't," a female voice came from behind.

As this happened, Ventus and Terra came into the cavern.

Not only were there four boys, but now there were two more mermaids in the water. The first one Ventus recognized just about straight away. The second caught Terra's eyes. She had sky blue eyes and short blue hair that went into bangs that went to the right side of her face as well as a blue tail and shell bra. She summoned a key-shaped sword, similar to the one that Ventus had earlier and pointed it in Sora, Roxas, Ventus and Terra's direction, a piercing glare on her face.

"What are you...humans...doing here?!" she questioned; she was clearly suspicious - and to be fair, she did have a right to be.

"Aqua; the rock fell-"

"But you can only get that to happen with a keyblade..." Aqua responded, now seeming a bit confused.

That was when she noticed that same 'keyblade' from before in Ventus' hand. "But...but how...?" Aqua questioned out loud. She was clearly puzzled, but the boys could see the suspicion in her eyes.

The four mermaids looked at each other. "I thought humans couldn't wield keyblades..." muttered the blonde girl.

"I know, Naminé...but somehow-"

The three boys received another surprise. They were now holding keyblades as well.

"This isn't right." Aqua gestured for the other mermaids to come with her, and they then swam through the watery abyss until they were out of sight.

Sora blinked in surprise. "Did that just happen...?"
