Another beautiful sunny day during the summer break in Germany. You could go outside, play soccer, go swimming or something along those lines...
Or sit in front of your computer all day, playing whatever video games you feel like playing. My daily routine at an age of 16 years.
I had my usual green shirt, light gray pants and green back-combed hair.
I was just playing Hyperdimension Neptunia, Fairy Fencer F or was programming my own game.
Yeah, just a normal day... At least, I thought so...

Peacefully sitting in front of my computer, typing away, a static-like noise came from outside due to my opened window.
I turned around on my chair to see a human-shaped blur fly through the same window. It seemed female, was wearing something black and definitely had purple hair.
When she smashed into the wardrobe opposite from the window, a lot of debris and dust were thrown into the air making it hard for me to breath. Additionally a sudden flash of light illuminated the room.

"Neptune!" Who was that? If the fact that a somebody just flew right through my window and smashed into my closet didn't make me worried, the voice sure did.
"Neeeptuuune!?" I decided to stand up and look through the window to anticipate something I would describe as a rift in reality, a portal or something along those lines.
In it (or behind it) I could see a girl with pink hair in a white and purple skin-tight suit with a worried expression. I could only guess why she was worried and I think it was a safe bet.
The rift seemed to be closing. I turned around again to see a girl with purple hair in some kind of white, ripped hoodie-dress, passed out.
"You!" I turned around once more. She seemed to have noticed me. "Give her this!" She threw me some kind of bottle with a blue liquid inside, unable to go through the rift herself anymore.
"What is this?" I asked her. But the rift had already closed. So I checked whether it had a label. "Nep Bull EX... Instant energy... Yep. Definitely crazy. I'm definitely crazy"
I pinched my cheek just in case this was a dream. It wasn't. "Well, let's do as she said."

Before I had the time to turn around once more and give the passed-out girl the Nep Bull EX, she was already gone.
"...Neptune?" I wondered, presuming it was the girl's name (in fact, I was pretty sure).

"Howdy, dude." I jumped from the sudden voice behind me to see the girl in question standing right there.
"Ok. Das wird mir grad zu viel..." I thought loudly, in the language spoken in this region.
"What are ya saying? Sorry, I don't speak something-ish." "Well, first: What just happened?"
"Probably traveling dimensions." She said that as if it was something one does every day.
Yep. Anything I assumed was pretty much confirmed as Neptune said that.

We quickly exchanged information of what was going on.
In the Hyperdimension Arfoire had not returned, instead 'Underling'/Linda and Pirachu were at it. They were causing a lot of ruckus in a district of Planeptune.
Well, the ruckus seemed to have been a trap for Neptune and Nepgear to come alone. They shot some kind of energy weapon at Neptune and hit her.
And the next thing Neptune remembers is waking up in my room on the floor. With ripped clothes.

Actually, now that I think about it, why aren't her clothes ripped anymore? I was sure they were earlier.
Just Neptune. Don't question it. Though I have a suspicion... I'll ask later.

Then I filled her in with the information of the dimensional rift and Nepgear worriedly giving me the Nep Bull EX.
Then some things about the location, what not do in this house, what not to do generally, not to climb onto me, etc.
And some occasional "Boring..." from Neptune during my explanations.

"I just realized, we haven't even introduced ourselves yet. Well, I'm Deniz, 16 years old, mainly playing video games in my free time."
"Hi, Deniz! I'm Neptune, CPU of Planeptune in another dimension and ..." "Spare me with your actual age." I cut her off. "Also, I kinda figured."
"Whatcha meaning? How do you know? You said you didn't have any way of traveling dimensions, did ya?" I pointed to one of the icons on my computer screen.
'Hyperdimension Neptunia Re;Birt...' It read, cut off by Window's text limit. It had Nepgear's face on it.
"Uhh... sorry, my brain is currently melting like ice cream in the sun." "I figured."


*Some more explanations later*

"So, that leaves us with figuring out how to bring you back to the Hyperdimension. And to explain my broken wardrobe."
"Nah, just leave the first to Histy and the later to me." Hell NO. I didn't say the last thing because there was no way of stopping Neptune from doing anything. I knew that.
And just like that, I heard somebody unlocking the door to the house and I knew who it was. My mom. And then I actually realized that she didn't even speak English, so there was a way of stopping Neptune. Hopefully.
"Actually Neptune. My mom wouldn't understand a word you say. And she just arrived. Since I don't have a plan, how about you tell me yours." I expected her to get the idea to hide it or something.
"Just say the truth. I mean, what kind of lie could cover up that." She said pointing to the closet. She was right. I had to admit it: Neptune. Was. Right.
Good thing I'm not a certain black haired girl. She wouldn't be able to agree to that.
"Let's hope she believes that..." I sighed. In that instant, my mother came across my room, seeing me sitting together with a girl next to me on my bed.

"Hallo, Deniz. Wer ist sie?" She pointed to Neptune. "Ihr Name ist... Neptune. Sie ist... eine alte Freundin... Ist es ein Problem, wenn sie einige Zeit hier wohnt?"
"Ich glaube nicht, dass das ein Problem darstellt." I silently told Neptune she could stay here a little, to which she just nodded. She's not acting like herself.
And the fact that Neptune ended up in a country where she couldn't understand anybody was great. Just great. "Oh, und sie kann kein deutsch." I told my mom, so she wouldn't even try talking with her. No point in doing so anyways.
Then my mom realized the debris still on the floor, came in, and saw the broken mirror and door. Turning to Neptune, I whispered to her: "This is gonna be a long day..."


Translations of the German text in order:

"Ok. This is getting too much for me."

"Hello, Deniz. Who is she?" - "Her name is... Neptune. She is... an old friend... Is it a problem to have her staying here for a while?"
"I don't think it's a problem."
"Oh, and she can't speak German."
