Decided to try my hand here. For those of you who know what this game/anime is like you might wonder why I'm here of all places. Well I just felt like seeing how writing here would go. Also using it as another stepping stone in writing although as you read this, the whole story is complete so I'm just going to upload it once a day. So let's get into this story of Hyperdimension Neptunia, AU. As always I don't own anything in here except the OC. Never have, never will. This statement is implied to all my stories.

PS. I would like to state that I will not really be writing a story, moreover exploring the idea of Sin and Purity coming together even though they are opposites. With that said, do not expect much of a story.

Chapter 1 Pure Sin

Rain. I've always liked the rain. Other people would hate it or can't even stand its existence. Me, well I have come to love it. It made me feel like all my worries were washed away. I opened my eyes and saw that the rain was still falling, peppering everywhere around me and dampening my clothes more and more. It sounded calming until I remembered what happened. I looked down at my hands. Red, my favorite color. It was deep red, crimson, the same as this man's blood. He was dead. Another assassin sent after me to try and gain my power. Power… always the object of desire. It would make these filthy humans fight and kill one another just for a taste of it. I sighed with pity and walked away back to my cabin in the woods so I could rest and dry my clothes. While I walked back, I looked at my hand again.

A triforce in the middle that was riddled with spikes. Around it were two wings on either side that curved upwards with two prongs, one for each wing, pointing downwards towards my forearm. Then around that was another set of wings that had the outer most part zigzag like lightning bolts. Then within the wings were a type of saw tooth blade that curved with the wings. One side black, another white, and in the center the two colors blended and had grey. I look up and saw I was at my cabin. I walked in and lit the fire and hung my clothes in front of it.

I stood in front of the fire, naked like the day I was born. I looked at my body. No fat, only muscle. It was a very nice amount of muscle although it was not grossly disproportionate. I walked over to the pantry that I had and took a bottle of water and drank it empty. I sat down in front of the fire and looked at it. crackling, breaking down the wood both physically and chemically. As I thought about the flames and how beautiful their red flickers were, two entities came up behind me, although I knew who they were. It was the dead warrior seraph, Jugundis and the broken demon Sigurus. These two haunted my every waking moment but recently I've grown to enjoy their company. Jugundis was always a weird looking fellow although I say this because he is always in a suit of armor.

The suit was as follows. The helmet seemed to just be a mix of ocean blue and sky blue and was a dome most likely to allow for maximum field of view. The helmet also had a stream of bright white hair that went down to about his waist. The pauldrons were weird. It seemed to be a three pronged claw that curved down then up with the larger claw having a tip that pointed downward and the smaller claws having a tip that pointed upwards. His torso was very well built. Even more so than me that it made the black fiber that covered him under the armor plates press against him tightly. The breast plate was large which always raised a few questions in my head. The arms seemed to be a simple two piece where one piece covers from the shoulder to elbow and another piece to cover from elbow to wrist. The gauntlets seemed to be just the black fiber except coming from the wrist armor were covering for the hands that also happened to be claws. Also, his legs were just various interweaving layers upon layers of thin metal that gave the illusion that it just came out of his feet and protectively wrapped itself around his legs. Again the black fiber was evident. The overall color of all of his armor was a slightly lighter shade of his helmets color which makes me think he was a warrior at sea. Finally he had a cape. Or maybe it was wings. Maybe tendrils but I just like to think it's a combination of all three because that is what it looked like. A black wing-tendril-cape thing that made him look pretty menacing. And of course his weapon of choice was a spear with a basic pole with a wrap near the pommel and basic blue blade. Then there was Sigurus.

He was also usually in gear although sometimes he would show his real body but that was scary. It even spooked Jugundis sometimes. It seemed like he took fencing gear and a set of knight armor and put both together to result in his set of armor. Similar to Jugundis's helmet, it had a stream of white hair coming out of it except it went from black to white with some tips being red like fire. His pauldrons and protective thigh plates seemed to be bigger than they should but if anything was out of place, it was his weapon. His weapons was a rapier although, you might as well call it a stalactite with a handle. Its length was the length of himself and he was pretty tall, Taller than me even. For perspective, I am 6'4 and he is 6'11 so he can easily impale someone in the ass and have it come out the top of their head with their brain on the tip. They both sat down next to me. The same goes with Jugundis, he was 7'1.

"So what's next Gene?" asked Jugundis. His voice was deep and gruff like a war veterans but it had an underlying smoothness which would help me out during our talks to help me relax

"To be honest with you, I'm not sure. These guys just keep coming after me, this world is done in because these dumb humans always destroy that which helps them live and don't expect any repercussions and when they happen, they will just run away to somewhere else. It's disgusting and the only ways to stop it are to either A. kill every last human and let the world just run wild with its own nature. And then there's B. take in all of the Sin that these humans have made which is to say a lot and I know Sigurus over here would like that since you two are still fighting over me, hehe."

I chuckled lightly as I thought about both options. Both would result in Sigurus just getting stronger but if I take the Sin in all at once and the memories associated with it, no more Sin will occur resulting in this world being damn near perfect. I looked to Sigurus and he simply looked back at me and then to Jugundis before back to the fire. I thought on the options before looking to Sigurus.

"Yo, Sigurus, if I take in all Sin and its memories, what could I do with it?"

He didn't say anything for a moment before looking at me.

"Anything." His voice was deeper and darker than black and more demonic that Lucifer himself. I thought on that one word. Anything. I asked him another question.

"What are the repercussions of using all of that power?"

"Anywhere from a temporary headache to Death." He spoke quickly

I stood up then and walked over to my clothes which were now dry. It was a black two button polo shirt with a black sleeveless undershirt. There was also a pair of navy blue jeans which were soft and loose allowing for easy movement and a fabric belt. I had a pair of black tennis shoes which had some mud on them still but I just put on a pair of socks and then the shoes which were also dry. I grabbed my two lucky charms, an Ace of Spades, and a black wire chocker with a similar style ceramic rectangle on it that on one side said 'Angel' on one side in white text written in Japanese and 'Demon' on the other side in the same style. I put the Ace in my pocket and the necklace on and looked at the two of them who were probably looking at me confused under their masks.

"Alrighty then, Sigurus. How fast can you take all of the Sin in this world and its memories and transfer them to me?"

"An instant"

"And how fast can you use that power to open a rift to a new random dimension?" I couldn't help but smile which was rare nowadays

"An instant?" he said in more of a question

"Alright then, do it."

"Okay, just be warned, you know the consequences." He held his hand out and simply snapped his fingers

I told him to do this because of two things. 1. This world was long gone and saving it would be a waste of my time. 2. I needed some excitement in my life. I wanted to fight something strong. I wanted to fight gods…

The room around went to pitch black and I couldn't feel anything. All I could see was a few specks of light pass by me before I saw the bright blue sky again. After passing through a few clouds I flipped around and saw that I was fast approaching the ground which was a grassy plain. I threw my left hand first which had the symbol. It glowed before letting me touch the ground softly thanks to reducing the speed I was going at. I looked around and saw four things that immediately that caught my eye. To the north was white. A lot of it, and if I squinted, I could see a pretty large city in the distance. To the south of it was a black blob that also seemed to be a city. Then to the east was another city that blended in with the surroundings a bit. A large green city with a large rectangular arch. Finally to the west was a large purple city with a spire in the middle that was its distinguishable feature. I was going to think something when the influx of Sin hit me like I freight train.

I knelt to the ground and felt it darkness circling inside me. It hurt like being stabbed with a sword that's red hot. If I didn't get rid of the Sin, then I would succumb to the pressure of it and die.I had no choice. I took all the excess Sin and used it in the form of an explosion. I don't know how big the explosion was but it left the ground as charred dirt and vaporized everything in a 100 meter radius although the pain subsided a lot and now but it was still there. He looked around and thought about what to do.

End scene. So I'm going to write it like this. Story chapter then a documentation paper on various things to explain some things in depth. Stay frosty felines
