At Fairylantica, Juvia was receiving a strict lecture from her father, King Makarov. Lucy was pacing around in anxious circles, for she knew how the sea king got when he was mad.

"I just don't know what we're going to do with you, young lady," Makarov scolded.

"Daddy, I'm sorry. I just forgot," Juvia tried to explain. "I—"

Makarov interrupted sternly, "As a result of your careless behavior…"

"Careless and reckless behavior!" Natsu added, floating above Makarov's head.

Makarov continued, "…the entire celebration was…"

"Ruined! It was done, finished, completely destroyed!" Natsu concluded, swimming in front of Juvia to rebuke her. "This concert was to be the pinnacle of my distinguished career." He pointed an accusing claw at Juvia, "Now, thanks to you, I'm the laughingstock of the entire kingdom!"

Juvia crossed her arms, "Right, Natsu… That's because you were held in such high esteem before all this."

Natsu argued, "Hey, this is not the time for jokes! And you don't have the right to make fun of your elders! You should be ashamed of yourself for ditching the concert, just when we were looking forward to it! You're an embarrassment to the royal family!"

Lucy decided she had enough of the way Natsu was talking to her best friend. She swam into the room and yelled at the crab, "But it wasn't her fault!" She turned to King Makarov, "Your Majesty, don't get too mad at Juvia. It's an error of judgment on her part as well as mine. We simply forgot the concert was today."

King Makarov and Natsu glanced at each other, before turning back to Lucy. "So?" Makarov asked.

Lucy explained, "First, we were exploring a sunken ship, collecting stuff, and then the Eclipse Pisces Shark chased us. But we got out of here just in time. And then Happy the Exceed came, and it was 'This is this, and that is that'—"

"Exceed?" Makarov questioned. "Is that the name of a cat from… the surface world?!" Realizing what she just said, Lucy gasped and covered her mouth with her fins. "You went up to the surface again, didn't you? Didn't you?!" Makarov exclaimed.

Juvia bit her lower lip briefly, "Nothing… happened."

Placing a hand on his forehead, Makarov groaned, "Oh, Juvia, how many times must we go through this? You could've been seen by one of those barbarians, by one of those humans!"

"Daddy, they're not barbarians!" Juvia argued.

"They are dangerous," Makarov shot back. "Do you think I want to see my youngest daughter snared by a fish-eater's hook?" He lifted his daughter's head with his fingertips. "We all remember a long time ago when your mother was crushed to death by a ship, a ship run by those treacherous humans! You don't want to suffer her fate, do you?"

"You know I don't," Juvia nodded, before she shouted, "But I'm seventeen years old! I'm not a child anymore! I can take care of myself!"

"Don't you use that tone of voice with me, young lady!" Makarov snapped. "As long as you live under my ocean, you'll obey my rules!"

"But if you would just listen…" Juvia started to cry.

"Not another word!" Makarov yelled, his voice rising to a nearly incomprehensible roar. "And I am never, NEVER to hear of you going to the surface again! Is that clear?"

Her lips trembling with anger, Juvia turned and swam out of the throne room with tears rolling down her face, with Lucy following behind.

Meanwhile, King Makarov sat back in his throne and sighed, "Perhaps I'm being too strict… I'm just… concerned for Juvia's safety."

"Hmph," Natsu scoffed, standing on one of the throne's arm rests. "Teenagers. They think they know everything. You give 'em an inch, they swim all over you."

Makarov asked Natsu nervously, "Um, Natsu? Do you, uh… think… I was too hard on her?"

"You, the king of Fairylantica, hard on your youngest daughter? Of course not!" Natsu confirmed. "You're just trying to protect Juvia from harm. After what happened today, she totally had it coming. It's her fault for getting herself into this mess. I mean, if Juvia's my daughter, I'd show her who's boss. No more of this 'flitting to the surface' and other stuff like that. No, sir. I'd keep her under tight control."

Makarov rubbed his chin thoughtfully, and smiled at that idea. He said, "You're absolutely right, Natsu."

"Of course I am, Your Majesty," the salmon crab nodded his head.

"Juvia needs constant supervision," Makarov decided.

"Constant," Natsu agreed.

"Someone to look after her, to keep her out of trouble."

"All the time."

"And you are just the crab to do it!" Makarov told Natsu, jabbing a finger into the crab's underbelly. The only reply he could give was a gulp.

Outside the palace, Natsu was grumbling angrily to himself. "Just had to open my big mouth… How could I be so stupid?! I should be writing symphonies for the concert hall every day, not tagging along after some headstrong teenager like Juvia!" Just then, he noticed Lucy giving Juvia her coral-pink treasure bag. The two looked to the left and right to check if no one sees them, before making their way out of the palace. "Huh?" Natsu said puzzled, and began swimming after them. "What's she up to this time?"

Natsu crawled onto a rock, panting heavily, and saw Juvia and Lucy stop in front of the entrance of a cave, which was covered by a large round boulder. Juvia pulled it forward before she and Lucy slipped inside, and the boulder began falling back into place. Natsu charged for the shrinking gap and only just managed to get through, but the boulder sent him flying into the grotto, straight into an hourglass. Natsu rubbed his head and groaned, before giving a gasp, "Huh?" His jaw dropped at what he had seen.

The grotto— which was obviously Juvia's— was filled with human treasures she collected from her previous ventures in the surface world. Shelves, trinkets, devices, and old junk; the likes of which Natsu had never seen before. He watched as Juvia lay on a rock in front of an old candelabra made for three candles, which currently held a knife on the left and a spoon on the right. As Juvia twiddled the fork in her hands, Lucy looked at her worriedly. She asked, "Juvia, are you okay?"

"If only I could make him understand. I just don't see things the way he does," Juvia sighed sadly, carefully placing her fork in the candelabra's spot between the knife and spoon. "I don't see how a world that makes such wonderful things… could be bad." Glancing around her grotto, she began to sing.

Juvia: Look at this stuff, isn't it neat?
Wouldn't you think my collection's complete?
Wouldn't you think I'm the girl
The girl who has everything?

Look as this trove, treasures untold
How many wonders can one cavern hold?
Looking around here, you'd think,
'Sure, she's got everything'

I've got gadgets and gizmos of plenty
I've got whozits and whatzits galore

Juvia swam over to one of the shelves on her grotto and picked up a wooden box, opening it to reveal several corkscrews, each one different from the rest.

You want thingamabobs? I've got twenty.

Juvia closed the box and placed it back on its shelf, then looked up at the hole in the grotto's ceiling.

But who cares? No big deal
I want more

Natsu couldn't believe what he just heard. She was actually singing about wanting a life on the surface!

I wanna be where the people are
I wanna see, wanna see 'em dancing
Walking around on those…
What do you call 'em?

Lucy waggled her tail fin. Juvia smiled, "Oh, feet." She pinched it, making Lucy giggle. Juvia then continued swimming around her grotto.

Flipping your fins, you don't get too far
Legs are required for jumping, dancing
Strolling along down a…
What's that word again?
Street

Up where they walk
Up where they run
Up where they stay all day in the sun

Wandering free
Wish I could be
Part of that world

Juvia and Lucy swam back down to the bottom of the grotto and lay on the sandy floor.

What would I give if I could live
Out of these waters?
What would I pay to spend the day
Out of the sand?

Betcha on land, they understand
Bet they don't reprimand their daughters
Bright young women, sick of swimmin'
Ready to stand

Juvia pushed herself off the ground, pulled a book off one of the shelves and opened it to show Lucy.

And ready to know what the people know
Ask 'em my questions and get some answers
What's a fire, and why does it…
What's the word? Burn?

By now, Juvia was practically shouting each word that her incredible singing voice produced as she rose up to the hole on the ceiling and stretched her hand out of it.

When's it my turn?
Wouldn't I love…
Love to explore that shore up above?

Juvia's voice then softened to the way it was when she first started singing. She swam down to the rock she was lying on before and sat on it as Lucy came up beside her.

Out of the sea…
Wish I could be…
Part of that world

Natsu, who had been quietly walking around the grotto watching Juvia, accidentally fell from one of the shelves into a tray covered with treasures, creating a huge crash. Juvia and Lucy turned to where the crash sounded, and gasped upon seeing who it was: a totally upset salmon crab sprawled on top of a rusted accordion with a pipe on his mouth, a necklace of beads and a hook all over his body, and his leg stuck on a small cup.

"Natsu!" Juvia exclaimed.

Natsu stood up and frustratingly shook the stuff off his body. He demanded stutteringly, "Juvia… What are you… How could you… What is all this?!"

"It's, uh… This is my grotto," Juvia replied innocently. "And this is… my collection."

"Oh, I see. Your collection," Natsu said calmly, holding up the hook, before he threw it down and started screaming his head off, "IF YOUR FATHER KNEW ABOUT THIS PLACE, HE—"

Lucy gasped and gave a worried look in front of Natsu's face, "You're not gonna tell him, are you?!"

Juvia begged, "Oh, please, Natsu. He would never understand."

Natsu chuckled, "Juvia, you must've been under a lot of pressure down here. How's about I take you home and get you something warm to drink?" He gently took Juvia's hand and began leading her out of the grotto.

Suddenly, a large dark shape passed over the grotto, blocking the light, and causing a low rumbling noise. This caught Juvia's attention.

"What do you suppose…?" Juvia wondered, and she swam away from Natsu.

"It's probably just a whale or something. Let's go, Juvia… Juvia?" Natsu looked around and spotted her swimming up towards the hole leading to the surface. "Juvia, wait!" He swam after her, followed by Lucy.
