Hyperdimension Neptunia is owned by Compile Heart, Idea Factory, Sega and whomever else worked on it.

I have NO idea where this came from!

Walking down the cold streets of the city, IF shivered slightly in her over-sized brown trench coat. "It sure if a crappy night." The brunette muttered and took out a cigarette from her pocket and put it in her mouth before lighting it up. "Where the hell are ya, Compa?"

A few minutes later, the echoes of footsteps caught IF's attention and she looked up as a blonde wearing a brown trench coat and hat walked her way. "Took you long enough." IF grumbled and put out her cigarette.

"Had to make sure that I wasn't followed." Compa said in a low tone of voice. "If we're not careful, this could blow up in our faces."

IF nodded as Compa pulled out a folder from the inside of her coat and handed it to IF, who opened it up and looked inside. "Woah, this is..."

Compa nodded at IF's expression. "Yeah, the Lowee trio's up to something. I think they're going to try and off Leanbox soon."

IF grimaced. "As much as I hate the bitch, if she goes down, Mobindustri would get a whole lot more dangerous, especially if the Lastation Sisters take over."

"I'm more worried about the Planeptune punks." Compa grumbled. "They might just be happy with being random and stuff, but you never know with them."

"Right." IF nodded and closed the folder before pulling out a phone and making a call. "You there? Yeah, it's me. Look, we got some... What do you mean boss-lady isn't around?!" IF growled and hung up the phone. "Fuck! Boss lady's dealing with a snitch and has to give them protection from that stupid gun nut."

"Well, well, well..." A mature voice had IF and Compa both going pale as they turned to see a young woman with long, purple hair done up in a mohawk, while wearing tattered jeans and a vest with no shirt on under it. "To think two of my former gang members would be in my territory after leaving."

"Listen, Nep..." IF began but trailed off as the woman came closer. "Purple Punk, we got out when you decided to off Uzume and take over the gang."

Purple Punk continued to walk forward before pulling out a large sword and smirking at the two as they trembled. "You two... If you had just ran away or quit the gang, I wouldn't have cared, but you went and joined the cops. You should be thankful it was me who found you. If it was Blanc, she or her sisters would have tied you up by your limbs to the back of their bikes and drove off, tearing you apart."

"And Noire and Uni would have given us cement shoes." Compa smiled nervously. "I don't mind going swimming with fishies, but not like that."

"And Vert would have used drugs on us to torture us." IF shuddered at the knowledge of what she knew Leanbox's crime boss was capable of doing. One of the girls that she had came across had been a former idol that had been an informant for the going-ons in the Leanbox cartel. When IF found her, the girl and her cousin, some sort of mad magician, had been so far gone that their minds were more of a mess than their bodies had been.

And that was after Vert's goons had gotten done with them.

Suddenly several gunshots rang out and Purple Punk let out a cry of pain as the bullets ripped through her thighs, causing her to fall to the ground in a spray of blood.

"That won't stop her for long! GET IN!" A voice yelled from a nearby car. IF and Compa didn't hesitate as they ran to the car and got inside, which turned and spun off at high speeds.

IF panted as she looked back at Purple Punk, who was already standing up. Seeing a glow coming from there, she sighed and slumped into the back seat of the car. "Thanks, boss lady."

The woman smirked at IF. "I told you, Iffy, my name's Arfoire."

So, basically, the nations are areas of a large city ruled by various CPUs in different types of gangs.

Planeptune - Neptune and Nepgear are typical American gangs/punks. You are picturing Neptune with a spiky mohawk and Nepgear with half her head shaved.

Lastation - Mafia-style. Noire dresses as an office lady and Uni has camo pants and a white tanktop.

Lowee - Blanc, Rom and Ram's biker gang. Hell's Angels if anything.

Leanbox - Vert is a "lady of the night" as a front as she does lots of money laundering and other illegal activities, but has "legit" businesses as cover.

IF and Compa, as you can tell, were former gang members that went straight. Arfoire, Linda and Warechu are all part of the police who try and keep things from getting too violent.

If anyone wants to take this idea and run with it, go ahead.
