Disclaimer: I do not own the Powerpuff girls series, unfortunately, they belong to Craig McCracken. If I owed the series, I would definitely have given it more episodes with the Boys and I wouldn't have allowed Demishita! Powerpuff Girls Z to exist.

Author's Note: With that said, I am excited to upload this story to the internet. The idea has been stirring in my head since a long time and while the plot is overused, I think I might be able to capture your interest.

Because there is just no way that the Powerpuff Girls and the Rowdyruff Boys would walk hand in hand and eat lunch together, if they ever decide to attend school together.

Chapter 01

The city of Townsville...

Is as peaceful as any day since the last seven years.

Years ago, financed by the kind-hearted donation of the good citizens of Townsville, the appearance of a 'permanent-security' prison was made. This new type of prison had been the project of a large staff of architects, doctors, psychiatrists, scientists and professors, who vowed to find a way to keep Townsville's criminals from breaking out of prison.

After two years of careful planning, this new prison was finally build just outside of Townsville. Dangerous criminals with a high risk profile, that have a long list of violence on their names, were placed in this high-security prison.

While this prison certainly helped with restraining most super criminals, the town was still frequently plagued by other kind of creatures, like monsters and aliens. It didn't take long for a clever, young Professor to get approval from the Mayor to experiment with genetic codes. It cost the city of Townsville a large sum of money, but the promise of no crimes and damage to property seemed to outweigh the cost of this project.

Eventually, seven years ago, a genetic force field was stabilized around the city. It offered protection against any non-humans that would visit the city. When this idea turned out to be a success, the idea was further enhanced: a black list was created. Normal-type criminals that continued to commit regular crime despite clear, official warnings were excluded out of the town after their sentence; with their DNA profile carefully stored. While the super criminals in the permanent-security prison receive a permanent ban from the city, the punishment would differ for the normal-type criminals, depending on the crime they committed. Most of the time, it wouldn't be longer than five years.

This large project that turned out to be a success, had changed the day-to-day life of its inhabitants completely. While most of them were delighted to walk around the city, without having to fear falling buildings, there was a shout of protest as well. A small percent of Townsville's citizens moved away, not agreeing to this form of protection they called a violation to privacy. Plenty of criminals decided to move away as well and even some super criminals preferred their freedom over their revenge.

All in all, the crime rates did eventually drop with 95%.

What this all meant for the young, seven-year old Powerpuff Girls, you ask?

A quiet chance to grow up...

Bubbles yawned. She and her sisters were walking down the halls. It was still morning and classes were just about to begin.

"What's wrong, Bubbles?" Blossom asked. Her eyebrow was raised in concern and the blond-haired girl couldn't blame her asking; she was always perky in the morning, unfazed by the early hours. And even through Blossom wasn't exactly their leader anymore, she was constantly fitting over her sisters.

She was probably still the most responsible one out of the three of them. And despite the fact that they're living a happy, peaceful family life with the professor, who is like a father for them... they never had a mother-figure. They loved their father dear to heart, so they never complained. But maybe subconsciously, Blossom picked up that missing part and played it, even though they were all the same age.

"I'm sorry, Blossom," Bubbles smiled. "It's just that I can't get used to sleeping in different beds."

Buttercup rolled her eyes. "Oh grow up, will you? We'd been sleeping in that same bed for years! I thought that we'd never get our own rooms. You know what, I'm glad to have my own place now. That way Blossom here can't steal my clothes!"

"Geez, Buttercup!" the red-head immediately cried. "It happened ONCE! And you didn't even wear that anyway!"

"That doesn't make it right! Besides…!"

Bubbles sighed as their small argument continued. A small smile appeared on her face. They haven't changed a bit, even through all these years. It made her happy, knowing that. The three of them were as close as they've always been.

While her sisters continued arguing, she hugged her backpack. Octi was there with her. The professor minimized him to a keychain. That way she could always have him close to her, without people making fun of it. She never stopped loving Octi.

The bell rang and Blossom and Buttercup immediately stopped their arguing. They were almost late for class!

"Soooo…" the bored tone of a low voice muttered. Green eyes watched the busy schoolyard below them with disinterest. "This is it?"

The sound itself should have been hardly audible through the loud wind that was blowing past them. But the guys with him could somehow understand him perfectly.

"This is exactly it," his companion smirked. It was amazing how his red baseball hat seemed to be unfazed by the wind, not moving an inch from his head.

"Great. This should be fun," was the reply of the shorter boy next to him. His blue eyes seemed to sparkle in excitement.

If any other student had been on top of that flat rooftop, he would have witnessed three people vanishing into thin air. All they left was a change of colour in the sky; only visible for a split second.

Lunch break. That is what the loud bell informed as it rang through the entire school.

For the Powerpuff girls, it also meant that their last class together had come to an end. They all had a different schedule for the rest of the day. Blossom, who made the Professor proud with a keen interest in Science, would follow it the rest of the afternoon. Bubbles was excited to spend it at Art Class; she never dreamt of missing it. Buttercup had never signed herself up for extra classes and was officially done for today. She was, however, not planning to sit back and relax. She was in the school's soccer team and there was a big competition coming up this summer. Whenever she had a free period, she would use it to train.

"Hey, girls," Bubbles announced on their way to the cafeteria. "I'll just drop my books into my locker. You go ahead."

"Okay, see you later!" Blossom smiled. She casually hooked her arm into Buttercup's, walking along with her. Buttercup seemed annoyed at the contact at first, but couldn't suppress the small smile on her face. Even though she wouldn't always admit it out loud, her sisters meant the world to her.

Bubbles giggled at the sight, before turning around. She passed the other students on her way to her locker, who were all heading towards the cafeteria as well. She turned left at the end of the hallway and immediately spotted her locker. She had put a heart shaped sticker on it, so that she could easily recognize it was hers. She had the top one, Blossom the one in the middle and Buttercup the one below. A coincidence really, because they never asked for it. It was funny that they were even connected to each other through their lockers.

But, she definitely didn't mind.

"Tell me, what are we doing here again?"

A large group of giggling girls passed them, taking glances at them and whispering to each other. The clearly irritated dark-haired youth glared directly at them.

"Now, don't be shy..." Brick teased him, placing his hand on his brother's stiff shoulder. He then send a dazzling smile to the group of girls, causing most of them to blush red on the spot. "You know why. Those girls can't use their powers at school. They'll be expelled once they do. It will be the perfect time to get revenge."

Butch slapped the hand of his shoulder. "Don't do that," he said angrily, referring to the giggling group of girls. "I really hate it when they start following us around. Since when have you become so interested in girls anyway?"

Brick shrugged. "They're fun to mess with."

"So about the Powerpuff girls," Boomer interrupted, bringing the two of them back on topic. "You want to start a fight in here?"

"Come on, that's no fun," was the immediate reply. The smile on his expression had faded. "We'll blow up the building, they'll get expelled for fighting us and that's it."

The blonde raised his eyebrow. "But… wasn't that pretty much the point?" he asked.

"Oh, no..." Blood-red eyes gleamed dangerously as he straightened his hat. "That isn't nearly good enough... Even killing them wouldn't satisfy me now. Expelling them is just one small step we'll take, in order to ruin their lives."

Blue eyes blinked in surprise, while Butch's arms unfolded in interest.

"But for now, we will let them know we're here," Brick continued. "And as long as we're not doing anything wrong, they can't do anything about it. We will mess with their heads first...there is no need to rush our revenge. We've been blowing up buildings for years. This will be a bit more interesting than that."

"So no fighting yet," Butch frowned. "Well, whatever. This can't be more boring than the last couple of weeks. Hey, Boomer I'm thirsty, get me a drink will you?"

His blond haired brother just stared at him. "Get it yourself."

Brick laughed. "Can't say how glad I am that you've grown a spine these last few years. Come on, we'll get it ourselves. I can use a Coke right now."

"I'm not thirsty, actually."

"Well, fine, suit yourself. Come on, Butch." The two of them walked away together, leaving Boomer behind. He didn't mind much, they were always together after all. Sometimes it was nice to be alone.

He leaned against the wall. There were hardly any students around anymore. Everyone had pretty much gone to the cafeteria already. He wasn't really hungry or thirsty himself. Even though he would never admit it to his brothers, being here made him nervous. Seven years ago they'd moved to another town, so they hadn't seen the Powerpuff girls since then. It wasn't like he was afraid of their strength or anything. Definitely not, they were a lot stronger than before, but…

But… they hadn't seen each other since they were children and… well… things were different back then, weren't they?

A loud thump interrupted his thoughts. "Oh dear…" a girl's voice resounded.

When he looked around the corner, he felt his heart skip a beat. A girl with long, blonde pigtails and bright, blue eyes quickly bend down to grab the pile of fallen books together. With one hand she shoved the books together. With the other she tried to keep her skirt down from crawling up.

It was like time had stopped. He recognized her immediately, even though it's been years since he last saw her. He felt his cheeks flush as the memory of that kiss went through his head, but he quickly dismissed it.

She was… tall, was the first thing that popped in his mind. He nearly hit himself for it. Of course she was tall! She's all grown up! She's… actually… kind of pretty.

Wait, what the hell was he thinking? She was a Powerpuff girl!

He looked around. The rest of the hallway was deserted. If he didn't take this opportunity, Brick would kill him. He had lost the nickname 'wimp' years ago and he wasn't willing to earn it back now.

Taking a breath, he forced his legs to move. He was almost right in front of her when she stood up with the pile of books and glanced at him. With a small cry, she dropped them immediately.

In an impulse, he grabbed her tiny wrist in his hand and pushed her against the lockers.

"Hello, Bubbles," he whispered. "Remember me?"
