Humanity's Demonic Machine (Gundam Book 2: Side Story)

Operation Black (#1- Black and White)

3 years later

The Pearl Harbor incident was a massive battle that left a scar on the Resistance and also on some YoRHa units. Not to mention the one who has been scarred the most is A2.

The chosen Gundam wielder is named after the vengeful god, Vidar. And a friend of her dead partner, Y/n Afam. But she knows that the fire of the Gundam never goes out, which either the YoRHa or Resistance would know or not.

Satellite Base Bunker [Classroom 1]

Inside a room, 3 androids of YoRHa are in session with the one in a Captain's clothing being the Instructor named Instructor Black. Its students seated in the chairs are model units, A3 and G4.

A3: *raises her hand* What are we learning today, ma'am?

Black: I will be covering your upcoming combat drills.

G4: Who are we fighting, ma'am?

Black: The enemies known as machine lifeforms. Millennia ago, Earth was attacked by aliens.

A holographic monitor screen shows in front of them and starts to show a presentation of the backstory of how doomsday has happened.

Black: The human survivors fled to the moon and live on today as the Council of Humanity. We androids now fight on Earth in their place. But just as humans created us to fight, the aliens created autonomous weapons known as machine lifeforms. Androids and machines are now engaged in a proxy war for the preservation of their respective creators.

The presentation ended as No.4 raised her hand to ask a question.

G4: *raises her hand* What will we be doing on that battlefield, ma'am?

Black: 8 hours ago, we received a distress signal from allied forces. Our mission is to descend to Earth and aid them however possible.

A3 raises her hand next as she has questions too.

A3: Is it just the three of us heading to Earth, ma'am?

Black: No... Our 2nd-generation members will join you, 1st-generation members.

As the lights illuminate the darkness behind them, it shows the 2nd generation of androids made after Operation Pearl Harbor: H9, S21, A6 & G22. Then, both first-generation androids asked Instructor Black to be in sync.

G4 & A3: Ma'am, what will be our position after the operation?

Black faces them and marvelously looks at them as a leader.

Black: What we become depends entirely upon our actions. We will beat back the machines and destroy the aliens! We will reclaim the Earth, once again. We are humanity's last chance and hope! We are the autonomous infantry androids: YoRHa!

Black finishes her speech with the official salute of their organization.

Black: Glory to mankind!

All: *salutes* Glory to mankind!

As everything went black a giant black box encasing an android inside mutters.

???: To mankind...

They are not knowing that a bright light has emitted far behind the Bunker and outcomes a Gundam's hand, ready to enter the deserted world of YoRHa.

Shibuya City [Ruins]

There are three Androids who are now scouting the area of a ruined city one of them is a G22, another is S21 and finally the other is H9. G22 is in the front checking their corners to make sure no one sneaks up behind or gets the jump on them.
