Doomsday (Harem x Male Reader)

Prologue

Y/N POV

You woke up groggily for school, you were not looking forward to School today. You walked into the kitchen to get some breakfast, where your mom was already cooking breakfast 

"Good morning sweetie!" Your mother cheers

"Good morning," You say, staring at the TV, currently on a news network

You stuff bacon in your mouth while you watch TV, with a warning reading 'NUCLEAR POWER PLANT FAILURE NATIONWIDE, EVACUATIONS ISSUED FOR EUROPE, CANADA, AUSTRALIA, JAPAN.....' the list continues on

"Uh... whats that about?" You ask your mom, pointing at the television

"That's weird, That must be new," Your mom says looking at the news on her phone,

You keep looking at the TV until the inevitable happens, it continues on '...JAPAN, CHINA, MALAYSIA AND INDONESIA, UNITED STATES...'

"MOM!" You yell, "We need to go!" You finish looking around trying to find your Mom

'Maybe she's already in our bomb shelter' you think

Your dad was a real doomsday fanatic, he always said one day there would be a Nuclear Power Plant failure or something, so he made a bomb shelter in your guy's basement, but sadly he died when you were ten...

You ran down the stairs with adrenaline pumping through your veins, you ran up to the vault door, but in order to access it you needed to put the PIN number in

You tried the first passphrase you can remember '9645',  the numbers are immediately replaced by the words 'INCORRECT' 

"Crap..." You mutter to yourself

You try another one, '8008', 'INCORRECT'

"Goddamit!" You yell, punching the machine,

You gather your thoughts and that's when it comes to you... '2017' you enter, 'CORRECT' it beeps at you

The vault door opens and you run in, but you don't see your mom inside... you try to run out but your too late, the vault door closed behind you

"MOM!" You yell, and that's when you hear a high pitch noise and everything begins to shake,

You see your cat Miori rub against your leg, while blissfully purring

"Not right now Mior-" You get cut off by something falling on your head

You slowly lose consciousness, as you see your Miori's body grow bigger 

Aiko POV

I was one of the few survivors left after 'Doomsday 2017', my little sister Ayumi and I were the only ones that survived in our family

"Do you have any water left?" My sister asks, dying of exhaustion

"No..." I say looking at my empty water bottle, "We'll be at our base soon though," I look at her gleefully 

"Are you sure? I've never seen that building before..." Ayumi says as she points to a metal building with  a roughed up vault door on

I look at the building with excitement, 

A new building! who knows what type of stuff is in this building!

My sister and I run towards the building, trying to think up ways to salvage the metal walls for tools we could make

Ayumi kicks the metal door open, which reveals something we haven't seen since before the doomsday

a male human...
