So... let me re-iterate the last day first:
I woke up at 6 am and immediately got a call from Histoire.
Then I dressed up and got the others.
We finished the call and played video games until about 7 am waiting for the portal.
After that Histoire called again and established the portal, which we went through.
In the Hyperdimension it was about 1 pm by that point.
Then we had a conference in case Arfoire returned somehow.
When that ended at ~3 pm, Vert 'talked' with me.
Then Neptune brought me, Diana and Linda to the guest room, where we talked over a few things.
That included things like inventory, status screens, skills, HUD, party and some other stuff.

And as it turns out, I and Diana didn't start off at level 1.
I don't get *why* but I was level 42 and Diana was level 36. Oh. And Linda was level 74.
So... uh... Note to myself: Don't mess with Linda. Yet. She's simply stronger than us from her encounters with the CPUs in 'former times'.

Then skills: I had 'melee'-combat attacks utilizing a sword.
Their names are... familiar to me and they mostly have a relatively low hit-count.
Diana on the other hand had magic-based attacks which don't require any weapon to execute.
Her skills have a really high hit-count and to top it, she can buff, create barriers and steal HP and SP.

And now to the actual plot.

We had already woken up and were dressed when Histoire came to our room to get us for breakfast.
"How was the night? Did you sleep well?" Histoire asked us, already leading us to the kitchen.
"I guess it was okay." "Yup!" "It was great." Linda, I and Diana said respectively.
Histoire replied. "That's great to hear." She made a short pause before continuing "Compa has made us breakfast today. I hope you like eggs and bacon."

We were greeted by Compa, IF, Neptune, Nepgear and all the other CPUs at the table... That's a huge-ass table.
"Mornin'." we greeted them back while we sat down. "Why are you still here? Don't you have like... a nation to rule?" I questioned.
Blanc gave an answer. "We've got competent oracles..." My eyes darted over to Vert who didn't seem to notice. "...who can do our jobs for a short period of time."
She paused a little to eat some more. "Besides, it was already late and Rom and Ram wanted to stay here overnight."
I looked at Noire... "L-like she said." ...then to Vert. "I wanted to talk to you some more."
"Consider using my definition of 'talk'." I replied stiffly. Vert choked a little on her food at that comment. "...sure..."
I was considering to ask IF where she went yesterday as she was clearly there when Histoire called the first time, but not when we came through the portal.
Probably a call from one of her phones, guild-stuff or something personal. Well... I honestly didn't really care.

"You know, it's funny how Underling is sitting at the table, eats with us and nobody even cares." Diana broke the silence again.
"My name is Linda..." the girl in question grumbled.
"To be fair, I'm still not comfortable with her. But I guess I can let it slide." Uni replied.
"She didn't do anything since she returned, did she?" Blanc added dryly.
"I somehow trust her." Nepgear returned.
"And she's also on the radar for some reason, so she's kind of on our side." Neptune argued.

Wait... "Speaking of 'she's also on the radar', why?" I realized something nobody even thought about.
The room fell into silence. For pretty long if I may say so. Even Neptune and the Lowee twins were silent...
Histoire finally broke the silence. "I'll get in touch with the other Oracles and talk with them about that. All we know right know is that she's connected to Neptune and Nepgear in some form or way."

Vert dragged me away once more to talk. I hope she's using the correct definition of that word now.
"CPU Candidate stuff again? Details about that?" I asked her dryly.
"Yes, of course." Vert replied. "I had a call with Chika yesterday after our conversation. We, for some reason, have a CPU memory in case Plan A doesn't work."
I'm assuming Plan A is what she suggested yesterday. "That's... uh... great. Any other conditions or offers?"
"Well, you'll get the all latest consoles,..." Sounds good... "...a high-end gaming computer,..." Sounds good, too... "...but you'll help me with my work." And as expected.

"To be fair... I kinda expected... all of that." I replied before pausing and quickly adding "...except *all* the consoles. But why would I complain."
Vert seemed cheerful, like she was getting a present. "So, what do you think?"
"Number 1: Diana is my sister. She should also become one. That's not a problem, is it?" "Well..."
"Number 2: You'll not address us as your siblings if you talk to us." "That's ok... I suppose..."
"So, I suppose you'll need to do some more calls now, I gotta talk to Diana about that." "...very well then."
"See ya around." I finished the conversation and left the room towards the living room.

So, how do I put it? I could hear screams from three girl, begging for mercy, and something zipping through the air.
Histoire did call the Ultradimension, right? ... Didn't take a lot more to guess what was going on...

When I arrived at the living room and stepped in, I could see a CPU with purple hair and a whip, presumably Iris Heart, a flipped-over couch and Neptune, Nepgear and my sister behind it.
"Obsidian Shield!" Diana shouted and instantly a barrier was created... which broke at the next hit of Iris Heart's whip. More screams ensued after that so...
I decided to act. Attacking a CPU! GENIUS PLAN! I drew out my sword and shouted "Terra Blade!" I swung my sword, firing a green energy beam at Iris Heart. She had no time to react, as nobody had noticed me before.
"Wha-" The attack impacted her and knocked her over the couch. The time it took her to get back up was used by the girls to get behind me.
"Oh, so you want to take me on? Or do you want to take their place?" The CPU asked me. "Honestly neither," I replied "but I *love* challenges."

She simply smirked and everybody else backed of some more.
"T. Blade Kick!" "Hell *no*! Star Wrath!" As she wanted to start up her EXE Drive, a large amount of glowing projectiles shot towards.
This skill easily interrupted her... Wait... it did?!
Additionally, she was knocked over the couch once more at which point a bright light enveloped her.

"That was easier than expected..." I thought.
"I-is it safe again?" a scared Neptune asked, peaking out from behind the door. "I suppose." I replied.
We got closer to the couch and as we stood right in front of it, a girl in a... pajama-dress(?), Plutia, shot up, surprising us.
Well, Nepgear seemed to have a heart attack and collapsed instantly.
"Whoops, did I do it again?" Plutia asked sleepily. "Almost. Well, you got Jr. here, but that's kinda different." Neptune replied.

"Let me guess, somebody woke you up?" I asked to which she nodded. "Who?" She pointed at Neptune.
Still my sword in hand, I slapped the purple ditz in question with the flat side of the blade in the face. "Ouch, what was that for?" She yelled.
I looked at her unamused. "Yeah, yeah, I get it." I put my sword back into my inventory.
"You seem to be pretty strong, if you can beat a CPU that easily." Plutia argued. "You think so? ... wait, what's your level?"
"76, why do you ask?" "I was... 42... You might have been tired." "Might have *yawn* been it..."
And just like that, Plutia fell asleep once more. "Let's... go somewhere else..." Diana suggested. But before we went to another place I picked up Nepgear to carry her.

Linda was sitting on a bed in the room we had for the time, fiddling with the device I had seen her use on the playground before.
"Yo, Underling, whatcha doing?" Neptune asked a little too loud. "WHA!" Yep, she was too loud, as indicated by Linda almost falling off the bed she sat on.
"*sigh* Just checking mails and stuff." She replied. I set Nepgear down onto a bed. "And... What happened to her?" Linda asked.
"Plutia happened." I told her and sat down next Nepgear. Diana and Neptune joined me. "Who- I don't wanna know."

"I almost forgot! Diana, I need to talk with you privately!" I broke the silence that quickly settled in.
"Yeah, sure, what about?" Diana asked. "I'll tell you once we're in private." "'k then."

"Yeah, I'm ok with that..." Diana didn't have a lot of things to say against us becoming CPU Candidates of Leanbox.
"...but I'll break her neck when something 'weird' happens." She added after some silence and a shiver ran down my spine. I knew my sister all too well.
"Oh my, you're... creepy." Vert had found us. And as it seemed, she also heard the last sentence.
What's it with people eavesdropping in this dimension?
"I suppose you accepted?" She asked. "Yup." We told her unison. "...But let's not do that immediately," I added "we have more important matters... or might have."
"That's wonderful." Leanbox's CPU replied when her phone rang. "Oh, excuse me, would you?" She left the room.
"Back to the Neps?" I asked Diana. "Yep." She replied.
