Beyond the fourth wall lies the land of the Gods; where your mere existence is to be used for their entertainment, fuel their carnal desires and be forever under their control. A step too far, and the virtual divide will be thrown into disarray.

Chapter 1: Reverse! Into Another World!

"Ouch... My head... Compa?"

"Ah! You're awake. Sweet, my sister has managed to help you out since you're unconscious." A boy's voice sounded soft and unusual for a petite girl, Neptune. Neptune uncomfortably sat up on a soft bed as she looks around the bedroom and finally looking at a teen's face.

"Uh, who are you? What happened to Gamindustri? Compa? Iffy? Nep Jr? Histy?"

"Who? What's Gamindustri? You're at Shinjuku in Japan." What the boy quoted had Neptune instantly checking through the window, and unfortunately this is no Gamindustri, no Planeptune, and all 100% humans and animals.

The sun shines brightly as usual with some clouds around it. Outside was full of people walking past and socialising together, the sounds of people's voices, the dogs are barking and cars driving past. The air is warm but fair. As the birds tweeting, Neptune's eyes widens in shock. "Um, Histy. We're not in Gamindustri anymore."

A parka hoodie vibrates in it's pocket, releasing a blonde fairy like oracle, Histoire. Rubbing her eyes, then freeze in shock. Turning her head up-left towards Neptune, Histoire could tell if Neptune messed with space and time continuum, or destroyed the fourth wall.

A teen gasped with excitement about a fairy in Neptune's pocket and then snatching her out as he's carrying her like a figure. "Wow a fairy! It's so real!"

Slap

"Hands off. Neptune, you and I will have a talk once we get back home!" Histoire growled, but what Neptune did was none of it. Neptune is slowly trying to smile but was abruptly stopped by the oracle's glare.

"So your name is Neptune? Cool, I'm Hanamura Mamoru. Nice to meet you, Neptune. Histy." Mamoru grinned as he stood off the floor and put on a handheld console for Neptune to play on. Histoire formally replied, "It's Histoire. And it's nice to meet you too Hanamura Mamoru."

Neptune on the other hand said out loud. "It's nice to meet you too, Mamoru! Let's hope we'll be great friends!"

"Thanks!" With both Neptune and Mamoru clapped each other's hand and shake it together, they've now become friends.

Later, Histoire realised what Neptune and Mamoru have in common. They're lazy, loud, eating and drinking (not alcohol) a lot and they play games like how Neptune normally does.

"You just couldn't let it go, do you?" Histoire muttered as she's slowly picking up cans and packets off the floor with her tiny body. Sighed as she threw away the garbage towards the bin. Histoire felt exhausted and can't be bothered to lecture Neptune any longer.

"Big bro! I'm home!" A cheery voice shouted which stops Mamoru and Neptune from playing on a Nintendo game.

"Mamori!?"

"Who?" Both Neptune and Histoire are curious about a girl named Mamori. Hanamura Mamori stops and went eye to eye with Histoire until an oracle gets manhandled again. "Wow! A fairy! How cute!"

"Get off... You're chocking me... And my back hurts!" Histoire chokes and reaches her arm upwards as being hugged is one of her worst moments ever. "Damn it, Neptune! Help... Me!" Histoire pleaded, but Neptune did nothing as she watches Histoire getting choked to death by a human girl.

Later, Neptune stood on the bed as she's introducing herself. "Allow me to introduce myself, I'm Neptune the main character who is lost and found in a place called Shi- Shinni- Shinji, Shinji!" Neptune mumbles as she doesn't know what to pronounce. Mamoru had an idea about teaching Neptune about the villages and cities of Japan someday.

Neptune continues "And this little fairy over there is Histy!"

Mamori then giggles and politely bowing to a purple haired petite and a tiny oracle. "That's cute. Neptune, Histy. It's nice to meet you, I'm Hanamura Mamori. I'm sure we'll get to know each other."

Histoire sighed and correcting a sister with the name "Histoire." Neptune has managed to catch an eye on one of her most favourite dessert of all time, Pudding.

"Is that... Pudding?" Neptune is shaking desperately with excitement for something to eat.

"Um yeah. Why do you ask?" Asked Mamoru who continue gaming uncomfortably. But that didn't stop Neptune from staring at the most beautiful, lustful, tasteful and mouth watering piece of sweetness.

"Can I have it?"

"Sure... If you want..." After Mamoru's answer, Neptune hastily zoomed past both Mamori and Histoire then dive towards a cup of pudding. Not only Neptune enjoys her favourite food but snatching a spoon and eat it like always.

... Later, downstairs in the house.

"Iffy, Compa, Nepgear, Noire, Vert, Blanc, Ram, Rom, Red, MAGES, 5pb, Cave, Marvy, Tekken, Falcom, Puchiko, Gust and Nisa? Weird names for some people you know." Mamoru murmurs while reading a list that Neptune wrote which has these names of her friends. A teen rubbed his black hair in confusion despite him and Neptune only met.

"Yup, have you seen them?" Asked Neptune. Since a petite and a teen are talking to each other, the smell of the food is coming from the kitchen where Mamori is cooking along with Histoire. Mamori paused and interrupted the conversation. "I know Rom. I work at the hospital in training. I'm sure you'll know her there."

"Rom in a hospital? How and why?" Histoire is slowing down her stirring after hearing "Rom" and "hospital." She wants to know about it.

Mamori is lowering her head slowly and twisting her long black hair by her finger. "Well... You see, Rom had a mental condition, also a PTSD which I can't tell. That's why she's been missing schools everyday. It's for the best that you should keep her calm."

"Easy! Will do!" Neptune replied

"Wait! You will? You'll see her?"

"Of course! She's been my friend since Nep Jr and her friends (CPU candidates) saved me and my friends (CPUs) in Gamindustri."

"And also, Rom is a CPU candidate of Lowee so you might say that, we're not from this world." Histoire finished Neptune's words off and continuing the dinner which was nearly prepared. Mamori then realised about where Neptune and Histoire came from. Covering her mouth with both of her hands, Mamori isn't the only one seeing this. "Then that means Cho-"

"'Choujigen Game Neptune' (Hyperdimension Neptunia) is real!? The actual 'Neptune' in our world!?" Mamoru interrupted and is overwhelmed by the fact that two videogame characters exist in their world.

"You could say that." Neptune felt a bit praised by two siblings she had only met.

Thud

A brunette has dropped down and pass out in surprise. Neptune and Histoire both slowly feeling guilt about scaring those from another world.

"Sister!" Shouted Mamoru, picking up his sister's back and carrying her in shock.

"NEPU!?" Shrieked Neptune, who may or may not scared her half to death.

"Oh no..." Sighed Histoire, knowing that they're in a lot of trouble.

A few hours later in the bathroom. Neptune is giving the oracle a shower despite Histoire being a pint sized oracle. There's steam coming out due to the heat and the bath is full of hot water. Neptune had a thought about seeing Rom tomorrow. Curiously Neptune asks, "So, is it bad that I get to shower you after myself?"

"No, Neptune... It's okay..." Histoire replied honestly. The oracle has become gloomy after being stuck with a Goddess whose a lazy pudding eater. In the end, they're trapped in another dimension.

"Ah!~ Don't go down there, Neptune!" Histoire exclaimed by feeling Neptune's fingers randomly sliding between her legs.

"Sorry, Histy!" Neptune instantly moved her hands off and remember to look where she's rubbing. "Jeez, you should've told me to open my eyes earlier. Like you told me: look but don't touch. And that's boring." Neptune mutters, then sulk while washing Histoire and herself. At least Neptune had one day of not going on a quest.

Outside at Shinjuku, it was dark as usual. The lights are on for people to see in the dark and there are very few vehicles active outside. A glitch has appeared out of nowhere as it summons a slime with dog features in the middle of the street. A dogoo has entered a world that was never a dungeon.

"Dogoo? Dogoo..." Sadly, a dogoo is lost in the middle of the night until a car crash happened.

Splash

"Oh God! Goddamn kids! Quit throwing buckets of water at me!" A man shouted and driving pass by, leading a dogoo to recover it's body. Not only a dogoo was mad but it was the first to show how furious a monster has become. "DOGOO! DOGOO!" A monster is barking non-stop at the car that's already gone.

Neptune and Histoire are now stuck in this new dimension which is known to be...

Alterdimension.
