Left fOr us: WiTHoUT HUMaN

A story about rebuilding the earth, an original story by me
Rated T for teen for blood, language, and themes
Vocaloids belong to respective companies (Crypton, Yamaha, Internet, etc.)
While reading the first chapter, I advise to listen to Miku Hatsune's God song (God Tier Tune according to Project Diva F) or through the whole story. That's how I imagine it. The story's similar to it.

Chapter 1: The Passion of Vocaloid

The Year 2059, Japan:

"All the CV's are functional, as is the new POID, MACNE, & SF."

"Good. Which one are we testing first?"

"The CV's. They seem to be getting along."

"Okay. Bring them in."

In walked in 4 small children, well, seemingly children. The tallest appeared to be 7 and had long pink hair to her mid-back with green-blue eyes. She wore a black headband with ribbons on the side and an amber yellow techno sleeve on the left arm. Her outfit consisted of a tight black strapless tank, a yellow jacket with fur on the sleeves, a black skirt to her knees, and a belt. Her shoes were yellow flats.
The next oldest seemed to be 5 with green-teal hair in pigtails. The pigtails were held by pink floating squares and she had green-teal eyes. Her outfit was a white shirt with a pink bow and fringe, black techno sleeves with pink trim, a black skirt, and pink sneakers.
The next one was a girl of 4 with short blonde hair in a white ribbon and pink flower barrettes. Her eyes were sky blue. She wore a white dress with yellow fringe, yellow bow, and white flats. She had black techno sleeves with yellow trim. Next to her was a boy who appeared to be her twin. He was the same age and had blonde hair that was slightly spiked with matching eyes. He wore a white shirt with orange trim, an orange tie, and black shorts. He also had black techno sleeves but with orange trim and had white sneakers.

"...I thought we were aiming for no twins."

"...There was an issue. Corrupted data with the original stuff so we had to improvise."

"What's their names then?"

"Luka Megurine, Miku Hatsune, and Rin and Len Kagamine."

The head scientist bent his knees to get the tiny children's level. He ruffled each one's heads. They were the future of the human race's fate. These Vocaloids would help mankind spread life, love, and music around the world. Most would be shocked the hands of their race were left to simple androids with a cool name, but it was happening. The scientist then saw some guards enter the room.

"What's wrong?"

"Documents were leaked to the public."

"What!"

"The public's outraged...Apparently, the thought of androids scares them. There's riots! People are pissed...The fear they'll rise up and kill the humans or some wacky doodle shit like that."

"They wouldn't hurt a fly! ...Figuratively. But a human! They would never!"

"They want it to all stop...It's getting bloody."

"...Dr. Crystal Fiona Mizura..." The head supervisor entered the room, addressing the head scientist, "Shut it down. The public's not happy. We'll continue this in 10 years."

"But...!"

"No buts!" The supervisor and guards left. Dr. Crystal turned to the four Vocaloids, who were playing with toys. So innocent, why would they hurt anyone?

"C'mon children...It's nap time." Dr. Crystal led them to the Cryogenics room, where the other Vocaloids were held. She went to four empty pods and opened them.

"We go in there?" Miku pointed, "It's cold."

"It'll get warmer. Just close your eyes."

The Year 2061, Japan:

Dr. Crystal paced the hallway, heading to the cryogenics room. She missed them. She missed all of them. She knew the world was in danger now due to their own careless actions, and now the world needed her creations: Vocaloids. Dr. Crystal opened the door after inputting the password, when she heard gunfire.

"They've invaded the laboratory!"

"AHHHHHH!"

"There's no more ti-!?" Dr. Crystal fell to the ground, clutching her bullet wound. Soldiers approached her, and some went into the room, "Don't...hurt them..."

"Up this a few years..." A soldier messed with the computer, "They're safe, missy. But you aren't."

"I don't care...As long as they...Live on..." She breathed her last breath, and lowered her head.

"Let's go. We took care of this freak show..."

The Year 3000, Japan...

*Time is up. Unfreezing. Unfreezing. Please standby. Unfreezing. Unfreezing.*

"Uwahhhhhh!" Out of pod 1, popped Miku, now 17 years old. Somehow, through magical means beyond the comprehension of the human mind, she wore a new outfit.
Her hair was much longer and now her pigtails were held by floating black and pink squares. Her shirt was white with a thin teal trim and a teal tie. Her skirt was pleated and black with the same trim. Her belt had triangles with a dark and light green shade. Her black techno sleeves were now transparent and longer without trim, and her shoes were black boots with a slight heel and green soles, "Such a long nap!"

"Mmm...It's dusty in here..." Miku noticed a thick layer of dust everywhere, and spun around to see another pod open: Luka's.
Luka was older now too. She was about 20, with the same long pink hair. Her headband was now brown and yellow without ribbons. She wore a black collared top with brass markings and a blue gem. Part of her midriff was revealed and her skirt was long with a long slit. Her shoes were laced yellow boots with black socks. Her techno sleeve was still the same though.

"Yawn...Oh Miku...You've grown." Luka was calm as she rubbed her eyes.

"So have you...So much older than me too..." Miku was slightly jealous. Partially due to Luka's D sized chest and her B sized chest.

"Where's everyone else?" Luka looked around, "Oh, sleeping. Should we wake them up?"

"Probably." Miku nodded, "I'll wake up Meiko-senpai and Kaito-senpai. You get Rin and Len."

"Then go from there...I see." Luka nodded.

Miku skipped over to the pods across from her and hit the green button. The lid came off and two beings stepped out.
Meiko was now 23, and slightly taller than Luka. She had short brown hair with matching eyes now. Her top was a midriff revealing red sleeveless top with the collar open and a grey strapless bra slightly exposed. Her skirt was red and slightly above her mid-thigh with a white belt. Her boots were brown with some black. Miku had to be even more jealous now due to the E sized boobs.
Kaito was also 23 and about Meiko's height, if not taller. He had short blue hair with matching lighter shaded eyes. He had a transparent blue scarf, a long white jacket with blue trim, a purple undershirt, black pants, and dark navy boots.

"Miku...?" Meiko yawned, still tired.

"Achoo! Why is it so dusty?" Kaito sniffled.

"Aiiieyeee! A spider! Kill it! KILL IT!" That was Rin. Screaming about a spider.
Rin's hair was still the same length, but now in white barrettes with her matching bow. She wore a white shirt with transparent poufy sleeves and yellow fringe. Rin still had her techno sleeves which were now transparent with yellow circuits. She wore black rolled up shorts with a yellow belt, and white sneakers with yellow soles.

"Rin...Just stomp on it...It's a tiny spider." And that was Len.
Len's hair was slightly styled more and in a small ponytail. He now wore a white shirt with a black collar, orange tie, and orange trim. His techno sleeves were like Rin's but with orange circuits. He wore black shorts to above his knee with an orange belt. His shoes were just like Rin's but with orange soles as well.

"It's dead." Luka stomped on it, wiping the spider guts off on the floor.

"Who else needs to wake up?" Miku asked Kaito and Meiko.

"Gumi, Gakupo...IA...Iroha..." Meiko listed.

"Miki, Nana, & Yuu..." Kaito finished the list.

"We're going to go outside!" Len and Rin were already out the door as they said that.

"...Are we sure they aren't twins?" Kaito asked, doubting it.

"Positive." Luka and Meiko nodded, "But it's convincing."

"Hello World! I am Len Kagamine! I am here to sing and spread joy across the world! I will give any type of performance as long as it doesn't involve me stripping! Just compensate me with treats and I will spread joy through music!"

"...Len." Rin tugged on his sleeve, sounding shocked.

"...What?" Len still had his eyes closed and arms wide open, as if trying to accept the world.

"Open your eyes you dumbass." She still sounded shocked, despite the insult.

"Eh?" Len opened his eyes, and realized why she was shocked.

The world was without humans.
