Hiii, thanks to all of you who favorited meh story, and feeeeellll freeeeeee to drop my a review!

Disclaimer; I DONOT own Harry Potter, Mermaid Melody, the songs in this chapter and the earlier ones, or H2O, or the last name Touin. I Do own my Oc, my plotline (mostly) and Yuuki's Pearl outfit. And the part of a song that she sings at the end of the chapter.

Harry, Ron, and Hermione rushed to Hagrids, figuring something out.

Harry quickly knocked on the door, and Hagrid opened it, and they entered.

Harry froze at who he saw sitting at Hagrid's table.

The girl had short, layered deep green hair, and grey eyes. She was wearing a light green off the shoulder shirt, and black jeans. Her skin was very pale. But what stood out the most was the large gash on her shoulder. Harry blinked. For a moment there, he thought...

"ah, heller, Harry." Hagrid greeting them, "This is, ah-erm..."

"Yuuki Touin." The girl-Yuuki-said. Harry stared at her, and she stared back. He removed her gaze from her. It was impossible. The hair and the eyes were wrong, and the girl would have said so.

"R-Right." Hagrid said, "Now let meh finish treatin' yer wound..." He brought a bowl full of water over to her, and her eyes widened.

"N-No! I mean-that is to say-I'm perfectly fine." Yuuki said quickly, standing up, heading towards the door. She stumbled, and Harry caught her before she could fall.

"You don't look fine, you know." Harry said quietly, helping her back to her feet. He noticed a slight blush on her cheeks. It was then that he noticed a necklace around her neck. It was a light green shell pendent with small wing-looking things on the side being a darker green.

"Ano...Excuse me, but does your school have a bath I could use?" Yuuki asked softly. Harry nodded, still slightly memorized by this girl.

"Yes...oh no- Hagrid! I need to ask you a few questions!" Harry exclaimed, and so the three students tumbled out their questions, while Yuuki carefully wrapped her shoulder up.

Harry's eyes widened after hearing Hagrid's answers, and all four- Yuuki, Harry, Hermione, and Ron-left, racing to the school.

But, before they could make it, Yuuki stopped dead, a hand on her head.

"Yuuki...?" Harry asked, taking a step towards her.

"Go!" She hissed, "I-I'll catch up with you!" Iwht that, she quickly dissappeared from view.

"Harry, we have to go, now! The Stone, Harry, the Stone!"

Harry snapped out of his trance, running with Hermione and Ron.

Yuuki's P.O.V

My mother, Lina, she had taught/told me about Gaito and his hench-people.

"Ah, the Green Pearl Mermaid Princess. We were starting to think-"

"That you wouldn't show up!" Two voices said, I looked up.

There were two girls, one looking about 16, the other about 13. One had long, icy blue hair, red eyes, pale skin, and spiked fins comin gfrom beneath her hair, that was the older one. The younger had short, red hair, icy blue eyes, pale skin, and spiked fins sprouting from her hair.

"You-You are..."

"No." The older one snapped, "We are not the Dark Beauty Sisters, but they were our friends, isn't that right, Sister Roro?"

"Of course it is, Sister Momo." The smaller one said.

"Now, we will take you to our Dark Master." They said together, and raised microphones before I could even utter a word.

"It's Show Time!"

My eyes widened.

"Voice in the Dark
Yami no foria
Shinju no kizuna ubae!"They started

I held my hands over my ears. T-this melody!

"Voice in the Dark!
Saa! Hajimaru
Utsukushiku karei na shou
Voice in the Dark
Uta ni nosete
Kodama suru yami no chikara!"

I crouched on the ground, trying to block it out.

"Heiwa nante maboroshi
Kagami ni utsuranu mayakashi
Nami no ito wo karamasetara
Hiki ushio ni naru

Kokoro ni aru maryoku wo
Itazura na biyaku ni kaete
Yowai mono wo
Madowasete yuku deshou

Voice in the Dark
Kuroi nami to
Kanadeau kono merodii
Voice in the Dark!
Ai wo tomete
Katachi naki kusari to nare!"

They didn't need to sing anymore. I could feel my vision going hazy.

"That was easy." They laughed, surrounding me with a red bubble. The red bubble was somehow filled slightly with water, and I changed back to my mermaid form. My mind finnaly quit swimming, and I was going to call out my Pearl, but the bubble somehow reflected their song, and I held my head in pain, eventually loosing sight of the things around me.

...(A/N- BTW, more than five dots by themself singals a T/S ((timeskip))

Harry's P.O.V (Sort of...)

"Now wait quietly, Potter I need to exaimine this mirror..." Quirrel commanded, leaving Harry to his thoughts. A muffled moan reached his ears, and his head swiveled around to see the green mermaid trapped in a red bubble. Quirrel's eyes snapped to her also.

"So, you're finnaly awake, Green Pearl Mermaid Princess." He said mockingly, "I highly suggest you stay quiet and submissive. It will make taking your Pearl so much less painful for you."

The mermaid growled.

"Use the boy...use the boy..."

"No.." Harry could hear the faintest voices say, "Green Pearl Voice!"

"Nananiro no kaze ni fukarete

Tooi misaki wa mezashiteta

Yoake mae kikoeta MERODI

Sore wa totemo natsukashii uta..." The bubble around her broke.

"Treating the both of us like this will not be forgiven!" The girl said.

Her voice... Harry thought, but shook his head.

"Pichi Pichi Voice Live Start!

Nagareboshi ni negai o kaketa
Nanatsu no hikari mitsukedashite
Hanarebanare ni natta JUERII SUTAA
Unmei to iu kizuna o shinjiteru

Tsumetai nami ni toketa
Namida no yukue wa
Darenimo kidzukarenai mama
Sotto awa to kiete itta-"

"Voice in the Dark
Yami no foria
Shinju no kizuna ubae!

Voice in the Dark!
Saa! Hajimaru
Utsukushiku karei na shou
Voice in the Dark
Uta ni nosete
Kodama suru yami no chikara!"

Harry looked at the two people who had appeared, then to the girl. She had her hands covering her ears, eyes squeezed shut.

"Ah, Momo, Roro, lovely of you to show up. Please restrain the Mermaid Princess." Quirrel commanded, and Harry watched in horror as the girl was surrounded in the bubble again, and reverted back to her mermaid form. Harry could hear echos of the song that the two strange people had been singing, and he could see the girl holding her head in pain.

As the time progressed, Harry kept an eye on the mermaid, who seemed to be unconcious.

...

(Timeskip, about when Dumbledore leaves Harry, and the others come in)

"Umm, Professor Dumbledore, what happened to the-" Harry paused, not sure if he should say anything.

"The mermaid?" He said with a twinkle to his eye. He pointed to a soor, "Right through there." With that, he left.

Harry begged Madame Pompfry, and she finnaly let his friends in.

"Harry! Thank goodness you're alright!" Hermione exclaimed.

"You too. Hey, d'you remember when I told you about the mermaid who saved my life this summer?"

"Yes...why?"

Harry grinned, "Follow me." He got out of his bed, walking to the door Dumbledore had pointed to.

He opened it, and heard singing, but it was below the water.

"Taiyō ga sora kara shizumu yō ni...

Umi made mūnraito...

Akarui hamon wa fukai no ikimono

ni yotte irowake sa rete imasu..."

"Umm...hello, anybody here?" Harry called. It was cool in here, and there was a gigantic pool with plants around it, and a lovely fountain.

"That's a stupid question." The girl snorted, surfacing at last, pushing herself up to sit on the side of the pool.

"Bloody hell..." Ron muttered, walking zombie-like towards her.

"Oi, Weasley, don't get any ideas." The mermaid glared, and Ron stopped dead in his tracks.

"How did you know his name?" Harry asked.

She grinned, "I just do, I know you all, but you may not know that right now. Tell me, Harry, do you know my name?"

Harry looked at her, but his eyes drifted to her shoulder, then to the water, her tail, her hair, then finnaly her face, "Y-You..."

"Yes?"

"You were the one to save me that day...you never told me your name, even when I called after you..."

Her look saddened, and she looked down, 'I...see..."

"But."

Her head whipped up.

"Even without your help, it is easy to see." Harry smiled.

Her eyes brightened.

"Your name is Yuuki Touin."
