Protections

Neville had forgiven Kaoru after their trip into the forest and the two could be seen studying together for their exams.

When the week of their exams finally arrived they were all worrying about whether they would be able to pass them.

Harry had a look of nervousness about him that worried the others a little.

After their last exam of the week the seven of them were sitting under a tree near the lake as Hermione, Miyako, and Takaaki went over their exam answers.

"It feels so great to be done with exams," Ron said while stretching.

Harry began rubbing his forehead "I wish I knew why this things hurting so much."

"If it's bothering you so much go see Madam Pomfrey" Momoko told him with a little worry.

Harry glared at her "I'M NOT SICK!"

"Harry! Apologize to her now. She was just voicing her concern for you. You don't have to bite her head off" Kaoru told him while looking like she was going to hurt him.

"I'm sorry. It's just that I can't shake the feeling we're missing something" he replied a little down.

He then jumped to his feet "I just realized something. We need to see Hagrid, now!"

They were all trying to catch up with him as they headed to Hagrid's hut. When they got there Hagrid was sitting outside shelling peas.

"Hello, have you come by for some tea?" he asked them with a smile.

"No, I'm sorry. I do have a question about the person you got Norbert from. Do you remember what they looked like?" Harry asked him nervously.

He shrugged "Not really, he keep his cloak on the whole time. But, that's not unusual at the Hog's Head, a pub in the village."

"Umm…Hagrid do you remember what you talked about?" Hermione asked knowing were Harry was going with his question.

He frowned "I told him I was game keeper here and the type of creature's I take care of. Then I mentioned wanting a dragon. He then asked me if I could handle raising one. So I told him that after raising Fluffy, a dragon would be easy."

"Was he interested in Fluffy?" Miyako asked him while fearing his answer.

"Well, I told him Fluffy's a piece of cake if you know how to keep him calm. A little music and he's off to dream land. I shouldn't have told you that," he said as his face paled.

They all told him good day and headed back to the castle. On their way back they were arguing about what to do. As they got into the entrance hall a voice asked, "What are all of you doing inside?"

They looked in the direction of the voice and saw Professor McGonagall holding a large pile of books.

Momoko was the first to respond, "Professor, we need to see Professor Dumbledore. It's very urgent."

"I'm sorry, but he left ten minutes ago on urgent business for the Ministry. If it's really important I might be able to help," she said with her steely gaze.

Miyako bit her lip then said "Someone's going to try and steal the sorcerer's stone tonight."

Professor McGonagall was so shocked by what she Miyako said that she dropped the books she was carrying. She recovered her composer quickly "I don't know how you found out about the stone. But, I will tell you that no one will be able to get it because of all the protections on it" she told them with finality.

Harry was about to protest more as Professor McGonagall picked her books up, but they heard a voice from behind say "Good afternoon, what are you all doing inside?'

When they turned around they saw Professor Snape giving them a Cheshire's grin.

"We were just heading to our dorms to get some books to read" Kaoru said trying to lead the others away.

Ron was going to say something but Hermione and Momoko grabbed him by his arms and dragged him away.

When they got to a deserted corridor Ron looked at the two who had dragged him away "What did you do that for?"

"Because Ron, if we hadn't you would've said something to tip Professor Snape off," Hermione said shaking her head.

"What are we going to do now? Professor McGonagall didn't believe us," Momoko said with worry.

"Well, I think one of us should keep an eye on Professor Snape. While a couple of us should watch the door on the third floor" Takaaki told them confidently.

Kaoru frowned "That won't work Takaaki. Professor McGonagall now knows that we know about the stone and Professor Snape looked like he was suspicious of us. They will both be trying to keep an eye on us all and that will cause Professor Snape to wait until after dinner before he tries for the stone. Which means we should wait until then before we try to stop him."

The others realized she was right and agreed with her to wait until after dinner to stop him.

That night after dinner they were waiting in the common room until everyone had went to bed before they would try to stop Professor Snape.

As they were sitting there Harry whispered, "I wish I knew were my cloak was."

Kaoru looked at him "Harry, I almost forgot I picked it up after the tower incident. I didn't think it would be wise to leave it there for anyone to pick up."

Harry shook his head and smiled before she continued, "The thing is though we'll need a way to get past Fluffy."

Harry got up and ran up to the boy's dorm room and back clutching something in his hand. When he got back he showed them the flute he had gotten from Hagrid for Christmas.

The others smiled knowing why he grabbed it. They then looked around the common room and realized everyone else had gone to bed.

When they got up and started to head for the portrait hole a voice asked, "Where do you think you're going?"

They turned to see Neville staring at them from behind an armchair.

"Kaoru, I thought you told me you didn't want to cause anymore trouble for Gryffindor" he said with an angry look in his eyes.

She looked down at her feet before she lifted her head and walked towards Neville with a determined look on her face.

Neville and her friends were slightly scared because they didn't know what she was about to do.

When she was in front of him she whispered "I'll explain everything to you eventually Neville. Just believe in us and me right now." She then grabbed him by his cheeks and kissed him on the lips (okay how many of you saw that coming). When she stopped and took a step back Neville's face was bright red with a look of joy and shock on it. She then took him over to an armchair and sat him down before he could pass out.

When she turned around Hermione, Miyako, and Momoko had their hands on their mouths and were red faced, while Harry, Ron, and Takaaki were slack jawed from the shock.

She glared at them "What never seen a girl kiss the boy she like's before? Get over it, we have a bad guy to stop before he revives a psychopath."

It took them a few more seconds to get over their shock, before they stared to head towards the portrait hole.

Before they headed to the third floor corridor Kaoru, Miyako, and Momoko convinced them to stop by a girl's bathroom so they could transform. The girls thought it would be a good idea to have their powers active before hand. It also allowed them to disguise themselves from anyone patrolling the corridors.

When they walked out of the girl's room Ron shook his head "I don't know if I'll ever get use to that."

Hermione was smiling though "I would love to have one of those belts."

"Hermione, we don't have time for that. We need to stop Professor Snape before it's to late" Takaaki said trying to get her to regain her focus.

"Takaaki's right. Besides, we can carry you to the corridor while we fly. It will be faster than sneaking underneath the cloak, because anyone who sees us flying at our top speed will just see three streaks of light" Blossom (Momoko) said as she grabbed Hermione's hand.

Bubbles (Miyako) grabbed a hold of Takaaki, while Buttercup (Kaoru) grabbed both Harry and Ron.

The three girls then started to float in the air before they took off at full speed towards their destination.

When they reached the door to the corridor they put their friends down before they landed. As they looked at the door they noticed that it was open a crack.

Harry cursed under his breath before he took out his flute and went thought the door followed by the others. On the other side of the door they saw Fluffy; a four and a half foot tall dog with three heads and midnight black fur. Before the dog could attack them Harry started playing his flute. Fluffy's heads started to yawn before he lay down and started to doze off.

The girls moved past Fluffy so they could open the trapdoor he was guarding. After they got it open they motioned for the boys to come over.

Ron looked down into the darkness that lay beneath the trapdoor "How deep do you think it is?"

"I'm not sure, but it can't be that deep" Hermione told him with certainty.

Ron looked at her confused.

Takaaki sighed "What she means Ron, is that if it was too deep then anyone coming to check one the stone would break their neck if they jumped down."

Ron smiled "So that means if we jumped down we should be fine."

"Yeah, but we don't know what's down there" Hermione told him, right before he jumped through the trapdoor.

Takaaki shook his head before jumping through after him, followed by Blossom, Buttercup, and Hermione.

Bubbles turned to Harry "Give me the flute so you can get down there. I'll float down after you're through."

Harry nodded and handed her the flute before jumping though the trapdoor.

Bubbles then stepped over the hole still playing the flute while she floated down to where the others were. When she got there she saw Hermione and Takaaki using their wands to clear a path through what looked like Devil's Snare.

They then headed for a stone passageway that sloped downwards for about fifteen minutes before they started to hear the sounds of bird wings. Before they stepped through the only door they had found Blossom, Bubbles, and Buttercup pulled out their weapons.

The chamber they had entered was brightly lit and as they looked up at the ceiling they saw what looked like jeweled birds.

Hermione quickly looked around the chamber and saw a heavy wooden door with a silver lock on it. Next to the door were about ten brooms. She smiled as she looked back up "I know what we have to do."

The others looked at her as she continued, "Those things up there are winged keys. We need to fly up there and find the right one to unlock the door so we can continue."

Bubbles thought for a moment then said "We don't have to all fly up there and exhaust ourselves trying to find and catch the right key" as she was talking she started to swing her staff back and forth starting to release hundreds of bubbles. She created so many that there was enough to capture every single key individually.

"Wow, now we don't have to try and chase them down to find the right one. But, how do we know which one to grab" Harry said in awe.

Ron went over to the lock and examined it "We're looking for a big, old-fashioned silver one.

"I think I see the one we need" Buttercup said flying into the air and grabbing one of the bubbles.

When she came back down they looked at the bubble she was holding. The winged key inside was just as Ron had described with bright blue wings.

Bubbles lifted her staff "Before I dispel the bubble you all should be ready to grab the key, in case it tries to get away." She then took the bottom of her staff, which was pointed, and popped the bubble.

Before the key had a chance to react to its freedom Buttercup closed her hands around it. She then walked over to the door and gently used it to open the lock, before letting it go.

The rest of them followed her into the next chamber. What they saw there astonished them.

The room was a giant chess set and they were standing behind the black pieces. On the other side of the room were the white pieces and behind them was another door.

Ron smiled as he walked over to one of the black knights and put his hand on it. The knight turned his head to look at Ron as he asked, "Do we have to join you to get across?"

The knight nodded, then Ron turned to the others.

"Look we all know that I'm the best at chess here so you'll have to listen to what I say," he told them with determination.

"I don't know if you're the best, because I haven't bothered to try and play against you. But for now we need to get across and you're our best bet" Buttercup told him with a smile, then "After we stop Professor Snape I want to challenge you to a match."

Ron smiled "All right, Harry and Blossom you are going to be the bishops, Hermione and Bubbles take over for the castles, me and Takaaki will be the knights, and Buttercup you're the queen."

After he said that all of those pieces left the board as everyone took their place.

Ron was moving them around the board with such expertise that by the time they were close to getting a checkmate on white the only pieces they had lost were pawns. White on the other hand only had its queen and king left.

Ron frowned "Well, there's no choice I have to be taken so Harry can checkmate the king."

Everyone looked at him with dread, except Buttercup who nodded in agreement.

Ron then moved into position and the white queen quickly captured him by striking him on the head. They all winced when this happened, but didn't move to help him. Harry then moved into place to checkmate the white king.

The white king handed Harry his crown before both it and the white queen bowed to them.

Takaaki went over to Ron checking if he was all right. He then looked at the others "He's breathing. I'll stay to look after him the rest of you keep going. We need to stop Professor Snape."

The others sighed with relief before they went through the doorway and down another passage before they came to another door.

As they stood in front of the door Blossom asked "I wonder what we still have to get past?"

"Remember what Hagrid said. Five of the teachers, Professor Dumbledore, and Hagrid helped to protect the stone. Hagrid used Fluffy, the Devil's Snare was Professor Sprout, Professor Flitwick must have charmed the keys, and Professor McGonagall transfigured the chessmen. That leaves Professor Quirrell, Professor Snape, and Professor Dumbledore's protections" Hermione listed all of the facts off.

Buttercup then opened the door and walked through followed soon after by the others.

The room they were in was only illuminated enough for them to see the other door.

Harry looked around "I wonder what we have to do to get to the next room?"

"You would have to beat us" came a voice from the shadows as three figures emerged. They were wearing long sleeve jackets with black on the sides and different colors on the front, with a belt strapped around the collar, black pants, black fingerless gloves, and black and white shoes with large circles on the outside.

The girls groaned and Blossom said "Not you three."

Hermione stared at her friends "Do you three know them?"

"Yeah, the one with the baseball cap and red jacket is Brick, the one with the blue jacket is Boomer, and the one with the green jacket is Butch. They're the Rowdyruff Boys, our evil twins" Buttercup told her.

Harry and Hermione were wide eyed in shock.

Brick looked at the five of them "We were told to make sure no one followed the Professor, but with you three here."

Butch started to laugh "Yeah, we have different orders if we found you."

"Ignore everything else and destroy you" Boomer grinned.

"Harry, Hermione get through the door, now! We'll take care of these three" Bubbles told them.

Harry hesitated a moment before grabbing Hermione and running through the door.

After the door closed Bubbles asked, "So, why are Professor Quirrell, Voldemort, and Him working together?"

The boys smiled and Brick said, "We'll only tell you if you can defeat and capture us."

The girls glanced at each other quickly and took to the air, while the boys started to move quickly on the ground with the wheels on their shoes.

Bubbles started to swing her staff rapidly yelling "Bubble Popper" causing hundreds of bubbles to start heading at the boys.

Brick countered by pulling his straw out and saying "Spitball Straw" aiming at the bubbles causing them to pop as he hit them with spitballs.

Butch then pulled off one of his socks and threw it at them yelling "Stinky Sock Boomerang".

Blossom used her yo-yo to block the sock yelling "Pumpkin Juice Spin".

Boomer pulled out his cotton swabs to start attacking, but Buttercup swung her hammer at him yelling "Swing Sonic". Boomer had to dodge out of the way or be knocked out.

Bubbles spoke up "Buttercup, Blossom we can't beat them with our weapons. We're to evenly matched."

The boys laughed, then Butch said "Evenly matched, yeah right. You're just girls, you're weaker than us."

The boys were hoping this would anger them so they would attack recklessly. They weren't expecting the girls to smile.

All three of the girls dispelled their weapons and said "Wand". Their wands appeared in their hands shocking the boys.

Boomer stammered "H-How d-did you d-do t-that w-with out d-detransforming?"

Buttercup smiled "One, our clothes we were wearing before transforming and weapons are in a pocket dimension. Two, we can will anything to appear from that dimension into our hand while transformed. And three, we've been studying magic for over eight months now. We're stronger than when we last faced each other in Tokyo" she then nodded at the other two girls.

Then all three girls flicked their wands and said "Wingardium Leviosa!" aiming at the boys.

The spells shot the boys so high into the air that they slammed into the ceiling knocking them unconscious. The girls then lowered them to the ground.

As they landed Blossom said, "I didn't think it would be that powerful."

When they started to approach the unconscious boys a voice was heard from the shadows "How unfortunate, they lost. I'll have to punish them for this. Till next we meet girls, I hope you live." The voice started to laugh maniacally as the shadows came off the walls and engulfed the boys.

After the shadows disappeared the boys were gone.

"Okay, now that was creepy. At least we now know Him is still trying to get rid of us. Considering that he sent the Rowdyruff Boys after us and he just helped them escape" Blossom said while shivering a little.

The girls then turned and headed for the next chamber.

A/N: Well Kaoru has finally said she likes Neville.

The reason Bubbles refers to Professor Quirrell instead of Professor Snape is because she witnessed him staring at Harry during his first Quidditch match just like Professor Snape. Also, through her, Blossom, and Buttercup's careful observations they realized that it was Professor Quirrell and not Professor Snape that was working for Voldemort.

Now with the fight against the Rowdyruff Boys was originally going to be the girls fighting Fuzzy Lumpkins. I decided against that because it wouldn't be fair for them to fight the second strongest of their villains this early in my fanfic.

Certain other villains from the girls' universe will show up. But there is one that I am defiantly not going to have appear in this fanfic, Mojo Jojo. I'm sorry for all the Mojo Jojo fans for doing that. But if you can give me a good reason or place in the Harry Potter storyline then I might include him.

And finally please leave me some reviews.
