A/N: This chapter will end the Megadimension arc with a revenge against ???. And the next arc is going to be a maturing one for Nero

2 weeks after the kiss - Nero POV

After the event with Uzume, we officially became a thing, and Umio doesn't stop to tease us about it

I trained myself hard, and came with excellent result

I am as strong as my HDD 100% right now, in my human form

(A/N: Ok, i will explain this: Nero have a limitless potential, and if he train, he can be much stronger, but, he is still weaker than the NEXT Form when transformed)

If that guy show up, this will be a different fight from the last time

I was with Uzume, searching for food, because our stock almost ran out

Uzume: Did you find anything?

Nero: No, and you?

Uzume: Nothing too

Nero: Let's go back to the base, it's been a few hours since our search, maybe Umio found something

Uzume: You're right let's go

As we walk back to the base, i felt someone following us, so i quietly told Uzume about it

Nero: Someone been following us for a while

Uzume: What do we do?

Nero: When i say 3, you run to the east, and i run to the west

Uzume: Okay, be careful

Nero: You two

As the stalker followed us, we prepared to run

Nero: 1...

Nero: 2.....

A bottle broke

Nero: 3!

We run each to our destination, the stalker appeared, and followed me

Nero: Seems like you pick up the wrong guy!

I run as fast as i could to the city, trying to trap the follower

I enter a building, hiding myself

Narrator POV:

As Nero hide, the follower followed him, but didn't find him

???: Where is he?!

??? 2: You lost him?!

???: It's not my fault!

She had a female voice, and it sounded like someone Nero know

Before she could argue some more with the other person, she felt something sharp behind her back

Nero: One move, you die. You will turn slowly, so i could see your face

She turned around, slowly and her faced revealed

She looked like.... Neptune?!

Nero: N-Neptune?!

Neptune?: Yeah that's me! How do you know me?

Nero: But how?! I thought you were still at planeptune when i was sucked by that portal!

Neptune?: What are you talking about?

Nero: Wait, you're not Neptune?

Neptune?: I am Neptune!

Nero: Okay, question: Do you have any sister?

Neptune?: Nope, but i really want one, why?

Nero: Okay now i understand, you're a Neptune from a different world

Neptune: Yep! 

Nero: Oh my god, i'm so sorry about this i thought you were someone with "him"

Neptune: Who's "him"?

Nero: Someone very strong and deadly

Neptune: Oooh, seems the scary one

Nero: You have no idea

Neptune: So! Who are you?

Timeskip - Nero POV

I told her who i am and how did i came here

She told me the portal was an error from Croire, someone captured in a book of her, and apologize about it

I told her it's nothing, and we made our way to the base

As we arrived, i felt the same aura that a month ago

???: Well, it seems like you survived after all

I turned around, met with him again

Nero: Neptune, go to the base without me, and try to find Uzume, explain her the situation and she should make an escape for everyone

Neptune: Okie dokie!

She ran into the base

I smiled at her childish attitude, that doesn't change no matter the dimension

???: Are you going to play the hero again?

Nero: How about you told me your name first? Because you know me and i don't know you, and it's so creepy

???: Alright, i can do this as your last wish before you die. My name is Akuma, and that's all you need to know

Nero: Because you think i want to know more about a jerk like you?

Akuma: Oh?

Nero: And a weak jerk to say at least, because you couldn't even kill me when i was at death door!

Akuma: Don't worry, i won't do that mistake anymore

We fixed each other, waiting for an opening

Akuma: Are you not transforming?

Nero: Not yet, it will ruin the fun

Akuma: And that we can agree

We rushed at each other, him being faster but without knowing, i dodged his punch, and counter with one of my own

But, he blocked it too

Akuma: Seems like you grow stronger in a month

Nero: Yes, and i will show you the result of my training!

I pushed him back, following close behind and punched him in the face

It.... did some damage?

Blood dropped from his mouth, he cleaned it and chuckle

Akuma: You truly are stronger, so it seems i need to go serious right now

He powered up, but, i wasn't afraid, or scared

I was excited for this fight

Nero: You powered up? So let me too!

I transformed into my HDD, and our power was equal

Akuma: It's going to be a fun fight

Nero(HDD): On that we can agree

(0:00 to 1:20)

We continued our fight at the city, where our fight raged on

Change POV to Uzume

I managed to make evryone go from the base, as Nero told this Neptune girl

She told me a strange guy came and said "you're still alive" to Nero

I'm worried about him, but Umio told me he can handle himself

Be safe, Nero....

Change POV to Nero

https://youtu.be/k5QQj7EzCCo

(0:30 to 1:08)

Akume: You truly are strong!

Nero: Shut up and fight!

We rushed at each other, sending punch and blocking it

He managed to punch me in the face, sending me flying, and followed with a hammer punch

Akuma: How's That?!

I got up, still bleeding from the hit 

Nero: Is that all you got?

Akuma: What?!

Nero: I said is that all you got?!

He became furious and rushed at me, but i dodged, and punched him in the guts

He backed away, holding his stomach

Akuma: You.... You... YOU MISERABLE IMBECILE 

He charged his energy into a ball

And send it to the core of the planet

Akuma: This dimension will be destroyed in a minute! This is your end, and my win!

He make a portal, enter it, and close it behind

I flew as fast as i could to the position of Uzume and Neptune, hoping they have a way out

But, as i was a few seconds away from the base, i felt their energy vanish

I was about to accept my fate, before i see a portal, still open

I rushed into it, it closed after i enter it, safe from the explosion

Nero: If i ever say bad thing about my luck, i punch myself in the face

I was still in my HDD form, since i don't know when Akuma will appear again

Nero: I just hope Uzume is safe

I was in a forest, and it truly was like the Virtua forest

I felt monster coming my way, and prepare to fight

The monster appeared, but they were..... afraid?

I approched, them, since they didn't have ill thoughts

The see me, and backed away, more afraid

Nero: Hey, calm down, i won't do anything i promise

They looked at me curious, but afraid

An Ancient Dragon approched me, and i offer him my hand

He recoiled back, but see i didn't try anything

He approched it, smelled it, and lick it

I pet him, and he enjoyed it

I wasn't prepared for the next thing

Every monster run at me, and licked me, like i was the first nice guy they met since a long time

After that event, i told them to go and hide, so they could stay safe. They didn't want to at first, but after i told thme i would be back, they did what i said

I walked for a few hours in the forest, encounter with monster of all type, and they were all nice

After a while, i was met with something shocking

It was a  girl, bleeding but still alive

Nero: Crap!

I managed to stop the bleeding, but i couldn't heal her completly

I used some of my Share energy to heal her

She started to wake up after a while

???: Where am i? What happened?

Then, she remembered something

???: Crap! I need to warn the other about the CPU!

Nero: And i don't think it's a good idea to move right now

She turned around, alarmed by my voice

???: Who are you?! Why did you heal me?! Are you an ally of them?!

Nero: Well, if a was with them, why would i heal you?

She stayed silent for a minute, but her guard was still up

Nero: And for my name, I'm Nero, a pleasure to meet you, miss...

???: Oh! I'm sorry, my name is IF

I was shocked, but since she was IF from another dimension, she will take my story seriously

Nero: I see, it seems like i-!

Before i could finish, a felt 4 entity, coming this way, Anti energy filling their body and another one, weak with share energy in it

Nero: Go and hide! Now!

She knew by my voice it wasn't a joke or something

???: Stop right here!

I hurried and hide too, hiding my energy too

As one of the energy came into my view to see it was Nepgear

But she was shot at the leg by someone

???: Now, you are not escaping

???2: You give us a hard time

???3: But your end is here

As the 4 other entity revealed themselves, i was shocked to see it was the main CPU, but.... different?

They approched Nepgear, who was sobbing

Nepgear: Please sis, stop...

P.H?: I don't have a sister if she is as weak as you

B.H: How about we torture her? It seems she can take some hit

W.H: I'm going to break her legs so she can't escape anymore!

G.H: Her scream will be such a pleasure

As they were about to attack her again, i revealed myself

Nero: So brave to attack someone when they are weak

They all turn to my direction, guard up, weapon in hand

P.H?: Who are you?

Nepgear: I-It can't be....

Nero: My name? You should remember it well

I powered up to my full power

Nero: I am Nero, and I AM THE STRONGEST CPU!

AND DONE

Oh my god, it's the second longest chapter i ever did

If it took so much time to come out, it's because i had trouble with the choice of dimension where Nero will be

The chaos CPU are as strong as Nero at 80% but, because of their synergy, they are dangerous foe

Next chapter: A brother fury
