World's End Harem (終末のハーレム)

S-Stop it!

Go ahead. Choose.

All the girls in that room have been gathered to mate with you.

2040 Tokyo

National School for Advanced Medicine

Erisa! I've always loved you!

I've known for a long time.

How long have we known each other?

Yeah...

We were together in elementary school, middle school, high school, and even college now.

This is really late!

But this year's the last year.

Next year, I won't be here.

What? Are you going on an exchange program?

I've contracted Cellular Sclerosis.

I wasn't feeling well, so I got a test.

And they told me to go to the hospital immediately.

Isn't that disease...

They say there's a pharmaceutical company with an AI working on a cure...

It's fine. You'll get better.

Yeah.

But it won't be ready for another four or five years.

I have to go into cold sleep until then.

Four or five years?

Well, it basically means it'll get better if I get some rest.

Just... I wanted to say this before I went.

Reito...

Maeda-senpai asked you out, right?

Are you going to say yes?

What do you want me to say, Reito?

I don't have the right to say anything.

I thought you liked me.

Well...

I still can't ask you to wait for five years...

All right.

Erisa...

And? And?

Rei-nii, how'd it go with Erisa-chan?

We got into a fight... and that was it.

I see.

Lucky for you, Mahiru.

Ow!

You should be the one to go into cold sleep, Ryuu-nii!

You didn't need to elbow me, though!

Hmph!

Did you have to hit that hard?

A society with highly sophisticated technology.

Food production, transport, communications, medicine...

An era when everything was done by machines.

Humans were released from the need to work for a living.

And now the only ones who work are those who find

it adds meaning to their life, or who feel a sense of obligation.

Hey, Reito.

Are you sure this is what you wanted?

It's the only thing I can do.

Ten minutes until your arrival at New Downtown Hospital #3.

They say it's gonna take five years for the medicine to be finished.

Mizuhara-san!

Mizuhara Reito-san!

It's not like I have a choice.

Coming!

Yup. No complications.

We'll be able to keep you nice and healthy during your cold sleep.

I'm relieved that you're my doctor, Takagi-sensei.

I guess even the genius of the school for

advanced medicine flatters his doctor when he gets sick.

Aww, stop it.

You're looking at a maximum of five years to make the cure.

Two to three if you're lucky.

You'll be cured when you wake up.

And when you do, you can go back to research and make a difference in the world of medicine.

Sure.

Five years, huh?

Rei-nii!

Work hard, okay?

Come back better!

I'm not sure what I can work hard at...

Rei-nii!

Sorry for worrying you, Bro.

Don't worry about us.

We'll see each other soon.

Mizuhara-san, I'm sorry, but the rules say you have to take that off.

Oh, okay.

Please, let me inside!

I'm sorry, only family is allowed in...

Just for a second!

Please!

Erisa!

Let her in.

She's family.

Onii-san...

Bro.

Hey.

Um... I came to see you off.

I'm not sure that's the right phrase.

To say good night?

I see.

Thanks.

Erisa.

Could you hold on to this for me?

You can give it back when I wake up.

Okay!

Rei-nii! Rei-nii!

You'll get better, right?

You'll get better right away, right?

It's finally time...

When I wake up, years will have passed.

And they'll be grown up.

I don't want to be the only one left behind...

Reito! Reito!

What's Erisa saying?

I'll be waiting for you!

I'll be waiting for you as long as it takes!

She really is cute...

Erisa...

No... it's not.

Good morning, Mizuhara-sama.

Um...

Good... morning.

I woke up from cold sleep?

Um, what year is it?

2045.

Five years... I was really asleep for five years...

Mizuhara-sama, let's start by having you take a shower.

Then we'll do a medical check.

Don't worry.

You're fully cured.

Really?

Yes. The cure was developed while you were asleep,

and then it was injected while you slept.

Whew...

Um, is Takagi-sensei here today?

I want to thank him.

He's... He's no longer with us.

Did he go to another hospital, or something?

No...

Um... there's some reason involving the hospital, right?

Sorry.

I'd like to see my family.

I'll explain, Mizuhara-sama.

Could you come with me?

Huh?

I'll explain what happened while you slept.

What's going on here?

I can't even see outside.

Allow me to introduce myself.

I'm your dedicated attendant, Suou Mira.

Attendant?

Yes.

I'll be seeing to your needs and handling any contact with the outside world.

Needs? I'm cured, right?

Yes. Completely.

Then why?

Um, you said you were going to explain what happened while I was asleep...

Could you do that now?

Very well.

Four years ago, a new type of virus, called the MK Virus,

spread around the entire world.

The MK Virus?

The infected die within three days.

The virus is transmissible through the air.

It caused a global pandemic within a very short span of time.

Four years ago?

Then there's a cure now.

No.

All the world's most advanced medical AI are continuing to work on the problem,

but no cure or vaccine has been found.

Look at this.

Distribution Station Exit | Entrance

Refugees?

The world's population has decreased by half over the past four years.

And it's become difficult to maintain

several of our technologies, including the food production systems.

Dropped by half?

That's impossible...

You're kidding...

Mizuhara-sama!

What's going on?

The whole city looks different?

What about my home?

What about my brother and Mahiru? Or Erisa?

Um, excuse me...!

Is that...?

Impossible... How?

He's alive?

Did I do something weird?

No, I'm not the weird one!

I haven't seen a single one since I woke up...

It's this world that's weird!

You've noticed, then.

The men...

Where did the men go?

The MK Virus, AKA the Male Killer Virus,

is, as the name suggests, a virus that is only fatal to men.

There are only women left in the world.

A very small number of men remain in cold sleep.

But 99.9% of men on this planet are dead.

Then what about me?

Why am I alive?

We believe it has something to do with your Cellular Sclerosis infection and treatment.
