I don't own Harry Potter or Powerpuff Girls Z.

Kaoru's Summer

When Kaoru stepped out of the fire she looked around the room as she moved away from the fireplace.

It was a room that looked like it could contain the entire living room and kitchen from the Weasley's house. There were three chairs covered in a fabric that made them look like they were covered in flowers, there was also a couch in the room covered in the same fabric. The room had three windows one on either side of the fireplace and one on the wall to her left. The walls were a navy-blue color and above the fireplace were a painting of what she assumed was the Longbottom family.

Kaoru was still admiring the room when Mrs. Longbottom stepped out of the fireplace. "I see you like the décor" Mrs. Longbottom said with a smile "I also noticed your wearing the earrings I helped my grandson pick out."

Kaoru blushed at this "I was just surprised that he even thought of giving me anything during Christmas."

"He told me he wanted to show you his appreciation for everything you did for him. I just suggested that the best thing he could do was give you a gift for Christmas and the best thing to give a girl was jewelry. Besides I had no use for them anymore" Mrs. Longbottom said as she sat down in one of the chairs.

"T-These were yours?" Kaoru asked in shock.

Mrs. Longbottom motioned for her to sit down "Yes, my late husband gave them to me when we first started to see each other."

Kaoru was starring at her "I'm honored that you would allow them to go to me."

"No need to be so formal dear. I figure any girl whose willing to help my grandson with his studies as much as you have could see the greatness that is hidden in him" Mrs. Longbottom said taking her hat off and using her wand to send it into another room.

"The reason I started to help him was I hate it when people pick on others just because it takes them a little longer to get things figured out" she told her trying to get comfortable in the chair.

Mrs. Longbottom nodded "If you don't mind I'll have Neville show you to your room. That way you two can talk while I get dinner ready."

Kaoru smiled and nodded.

"NEVILLE! YOUR FRIENDS HERE!" Mrs. Longbottom shouted with strength of voice from a woman three-quarters her age.

Kaoru was quite startled by Mrs. Longbottom's shout because she didn't expect her to be that loud.

They then heard what sounded like someone running down a flight of stairs. Just then Neville walked through the door with a red face and trying to catch his breath.

Mrs. Longbottom waited for him to calm down before speaking "Neville, show Kaoru to her room. I'll have dinner ready in two hours."

He nodded as Kaoru got up and followed him out of the room. He then led her up the stairs to the second floor, which had a hall heading off to the left and right. Neville walked down the right hallway stopping at the third door on the left.

He turned to her "Well, here's your room. Mine's the one across the hall" he indicated the door directly across from hers.

"I'm surprised your grandmother is willing to let me have a room so close to yours" Kaoru told him with a raised eyebrow.

Neville smiled at her "When I told her everything that went on between us through out the school year she said that you reminded her of someone that she knew and could be trusted."

Kaoru was a little startled by this but smiled "So, where's your grandmothers room?"

Neville pointed to the door on the left side of hers.

Kaoru giggled, "I should've known. Well, since we have a couple of hours before dinner there's something's I want to tell you" she then opened the door to her room and walked in followed by Neville.

When she walked into the room she saw the bed against the opposite wall of the door with her trunk at the foot of it. Against the left wall were a dresser and a bookcase with a few books on it. Against the right wall was a desk below a window with an unused candle on it.

Kaoru walked over to the bed and sat down while Neville sat in the chair at the desk.

"What did you want to talk about?" he asked her a little nervous.

"You remember that night at school when the others and I snuck out of the dormitories" she asked him.

Neville nodded wondering where she was heading with the conversation.

Kaoru closed her eyes and took a deep breath before continuing "I told you I would explain everything to you."

She then proceeded to tell him everything that had happened to her and her friends. Starting from the day she became a Powerpuff Girl up to the night they stopped Professor Quirrell from stealing the Sorcerer's Stone.

Neville was in complete shock by what she had told him.

Kaoru stood up and walked over to him, because he wasn't moving. She waved her hand in front of his face to see if he was all right. When that didn't work she snapped her fingers in front of his face then she started to shake him back and forth.

This finally snapped him out of his daze "Sorry Kaoru, it's just everything you told me was a lot to take in. But, why did you tell me all of that?"

She sighed "It's because I love you Neville and I don't want to keep any secrets from you."

"Are you sure you want to trust me with all of your secrets?" Neville asked her nervously.

"I'm sure," she told him as she leaned into kiss him.

Just then they heard Mrs. Longbottom yell saying that dinner was ready.

They both sighed before they left Kaoru's room and headed down to dinner.

A couple weeks later on July thirty-first Kaoru had gotten up early to help Mrs. Longbottom get things ready for Neville's birthday.

"I hope Neville like's the gift I got him," she told Mrs. Longbottom as she helped mix the cake batter.

"I'm sure he will dear. I'm just surprised that he's gotten so good at the martial arts you've been teaching him" Mrs. Longbottom told her while pouring cake batter into three pans.

Kaoru started to put the pans into the oven "It surprises me a bit too. He's been learning the moves I've been showing him faster than I thought he would. I'm also glad that you were nice enough to teach me how to cook."

"Its my pleasure. I'm just surprised that no one taught you how," Mrs. Longbottom said as she started to work on breakfast.

Kaoru shrugged "I never really wanted to until now. When I was with my family all I ever did was compete against my brothers in sports and at the Weasley's I didn't want to bother mom about it."

"That reminds me why have you been calling Molly and Arthur mom and dad?" she asked her as she started to cook up some eggs.

"Its because Mrs. Weasley said that since her and her husband are our legal guardians while we're here in England it made us a part of the family. So they wanted us to call them mom and dad" she replied as she was buttering some toast.

Mrs. Longbottom laughed "That is so like Molly. She's always thought of all the children in the world as hers. You know on the day Lord Voldemort was defeated she actually begged the Minister to let her adopt Harry" she told her with a somber smile.

Kaoru shook her head "It would've been a lot better than where he lives now."

"What's wrong with were he lives now?" Mrs. Longbottom asked with some concern as she started to cook some sausages.

"From what he's told us his relatives treat him like a slave. They make him do all the chores, starve him, and beat him if he gets out of line" she told her as she was setting the table.

Mrs. Longbottom stopped moving for a moment "Are you sure about this?"

"Yes I am. I may have only known him for about nine months, but I know no one would lie about that. Especially with those scares on his back" Kaoru told her with a shudder.

Mrs. Longbottom finished cooking breakfast and then pulled the cake pans out of the oven to let them cool. She then turned to Kaoru who had just finished setting the table "Does he know who left him there?"

"He told us that Hagrid was ordered by Professor Dumbledore to leave him with them" she told her.

"Really" Mrs. Longbottom said as she walked to the bottom of the stairs "NEVILLE, BREAKFAST!"

After a few minutes they were all sitting down for breakfast. There were no words spoken during the meal, which made Kaoru and Neville a little nervous because Mrs. Longbottom was always making conversation while dinning.

When they were done Mrs. Longbottom gave a flick of her wand sending the dishes off to clean themselves. She then left the room after saying to meet her in the living room.

When she got there she gave them a slight smile "Now I want you two to hold on real tight while I apparite to St. Mungo's"

They both grabbed one of her arms before they felt a pull behind their navels and they appeared in the reception hall of a strange place.

"Umm…Mrs. Longbottom, where are we?" Kaoru asked her looking around.

"We're at St. Mungo's Hospital. Wait here while I tell the receptionist we're here" she said as she walked up to the counter.

Kaoru looked at Neville who seemed a little nervous "Neville, why are we here?"

"Me and my gran always come here on Christmas and my birthday. The reason we do is because my mom and dad are permanent residents of one of the wards" he told her sighing.

She gasped putting her hand in front of her mouth "I'm so sorry, I didn't know."

Just then Mrs. Longbottom came back "I see you told her why we're here. The reason my son and his wife are here is because they were tortured into insanity by Lord Voldemort's followers" she said as they walked up a flight of stairs to the fourth floor and came to a door with the name "Janus Thickey Ward" on it.

As they walked into the ward Kaoru saw that there were only two people in the ward. A man and a woman both of whom looked thin and worn out with snow-white hair that was wispy and dead looking.

Kaoru followed hesitantly behind Neville and his grandmother.

When they got near the beds of the people Neville smiled "Hi mom and dad. It's my birthday today, so we came to visit you again. I also brought a friend to meet you, her name's Kaoru" Neville then gestured for her to move closer.

As she moved closer to the beds Neville's mother got up and walked towards her. Neville's mom then reached out a hand and put it on Kaoru's shoulder.

When she did this something unexpected happened. Her eyes regained their focus, her skin got some color back, and her hair no longer looked dead. She blinked a few times then looked from Kaoru to Neville and finally to Mrs. Longbottom "Augusta, its nice to see you and Neville again on his birthday."

Neville was in shock and Mrs. Longbottom quickly took a seat on one of the beds when she heard this.

"H-How is this possible?" Mrs. Longbottom asked starring back and forth between her daughter-in-law and Kaoru.

Neville's mom started thinking then shook her head "I'm not sure. All I know is that when I touched Neville's friend here my mind came into focus. And for some reason I don't want to take my hand from her shoulder" she tightened her grip on Kaoru's shoulder making her wince a little.

Kaoru took a moment to focus her eyes on Neville's mom. She was shocked to see a few wisp of an evil aura coming from her body. She then turned to look at Neville's dad and found that he was also afflicted by the same aura.

"Neville, I think I know what's happening. It has to do with what I told you about my home town" Kaoru said as she turned to look at him.

"Is there anyway for you to make it permanent?" he asked her hopefully.

She shook her head "Not with out Professor Utonium's help, I'm sorry."

"It's all right Kaoru. Just the fact that your able to do this is amazing" he told her as he began to cry.

Kaoru then moved towards him with his mother so they could both hug him.

Mrs. Longbottom got up and joined in the hug.

When they stopped hugging they stepped back with Neville's mom still holding Kaoru's shoulder. For the next hour they talked trying to get her caught up with everything that has happened over the past few years.

When it came time for them to leave, Neville's mom reluctantly removed her hand from Kaoru's shoulder. As she did this her looks returned to what they were when they first arrived.

After they got back to the Longbottoms residence Mrs. Longbottom turned to them both "Now, you will both tell me what you were hinting at back there or else."

They both gulped realizing that they had no option but to tell her everything.

When they were done telling Mrs. Longbottom, she got up and gave Kaoru a long hug.

After Mrs. Longbottom let Kaoru go they then went into the kitchen and finished making Neville's birthday cake before giving it to him. Before they ate the cake they gave him his birthday presents. He got lots of clothes from his relatives and Kaoru had given him a set of weights.

A week later when Kaoru came down for breakfast she found Neville sitting there reading a letter.

As she sat down Mrs. Longbottom handed her an envelope "You're school letters arrived this morning."

Kaoru opened her letter and the first page said not to miss the Hogwart's Express on September first. The second page had the list of new schoolbooks:

The Standard Book of Spells, Grade 2 by Miranda Goshawk

Break with a Banshee by Gilderoy Lockhart

Gadding with Ghouls by Gilderoy Lockhart

Holiday with Hags by Gilderoy Lockhart

Travels with Trolls by Gilderoy Lockhart

Voyages with Vampires by Gilderoy Lockhart

Wanderings with Werewolves by Gilderoy Lockhart

Year with the Yeti by Gilderoy Lockhart

Kaoru stared at the list "Why are all but one of our new books all written by the same person?"

"What do you mean?" Mrs. Longbottom asked as she took a bite of toast.

Kaoru handed her the list. As she looked down it she gave a deep frown "It looks like you're new Defense Against the Dark Arts teacher is a fan of his. I hope you all will actually be able to learn something if they are."

"What do you mean gran?" Neville asked with a little worry.

"Most people who are fans of Gilderoy Lockhart are what I think Kaoru told us her friend Momoko is when she has a crush on a boy, fan girls. A lot of which are around Molly's age. Its embarrassing really" she said sighing as she gave Kaoru back the letter.

"Great, just what I need. An older version of Momoko as a teacher" Kaoru said as she shook her head.

"Well that aside, when do you two want to get your school supplies?" Mrs. Longbottom asked them.

Neville looked at Kaoru "We could go after breakfast today. It's not like me and Kaoru have anything else to do. We've finished our summer homework and she told me to take the day off from my physical training."

"That sounds like a great idea, but I'm afraid you two will have to go by yourselves. I have a very important appointment after breakfast today" she told them as she got a drink of orange juice.

"All right, I'll make sure Neville and I get everything we need" Kaoru told her with a smile.

Mrs. Longbottom nodded before they all went back to their meal.

After they were done with breakfast Mrs. Longbottom set the dishes to washing themselves. They then went upstairs to get ready to leave and meet in the living room.

Mrs. Longbottom walked over to Kaoru and handed her a small pouch before giving Neville a key "The pouch has enough Floo Powder for you to get back here and the key is to our vault at Gringotts. I'll see you two later" with that she apparited out of the room.

Neville looked at Kaoru as she threw some Floo Powder into the fireplace "This is the first time my gran has let me go to Diagon Alley without her. That must be a very important appointment for her to do that."

"Whatever the reason, we need to get going to get our school supplies" she told him as she grabbed his hand and stepped into the fireplace "Diagon Alley" was the last thing she said.

When they got to the Leaky Cauldron she started to run out of the tavern to Diagon Alley dragging Neville behind her. She didn't stop until they were right in front of Gringotts.

In Gringotts they went to the nearest unoccupied goblin.

He looked over the counter at the "What do you need?"

"We would like to get some gold from our vaults" Kaoru said with a smile.

"Keys please" the goblin asked in a monotone.

They both gave him their keys. When he saw Kaoru's his eyes got wide "I'll take you to your vaults personally."

After he had given them back their keys they followed him into the back of the bank to the carts. Their first stop was the Longbottom family vault.

Kaoru looked on as Neville entered his vault and gathered a hand full of gold. She noticed that his vault had about a tenth of the amount that was in hers.

After Neville got back on the cart they headed down to Kaoru's vault. When they got there and her vault was opened Neville nearly passed out from shock at the amount of gold in it.

As she came back to the cart after grabbing some gold and a few books, Neville shook his head "I know you said you had a huge vault, but I didn't think it was that big and what's up with the books?"

"These books are my ancestors autobiographies. I'm reading them to find out more about her," Kaoru explained as they made their way back to the bank entrance.

When they left Gringotts they made their way around Diagon Alley picking up their school supplies. After they had gotten everything they went back to the Leaky Cauldron and headed back to the Longbottom's house.

A/N: I hope you liked the chapter. Next is where the cannon starts up again.

I bet everyone is wondering who Neville's grandmother had an appointment with that she was willing to let him go by himself to get his school supplies.

If you can guess then I will tell you, but if not then only time will tell if I will reveal it or not.

Finally please review.
