I think it's about time we woke her up.

Y-Yeah...

If she catches a cold, she'll be even more useless at the tournament.

Wait. This is an opportunity too good to miss.

Later.

Um, she whisked her away...

Will she be okay?

I think she's in good hands with Kurusu.

Chitose's a trooper.

I'm back.

N-Not that I was worried...

I'm more worried about how little time that took.

Silence, ignorant masses.

Who're you calling "ignorant masses"?!

I think you'll change your tune after seeing these.

They're so... large.

It's true!

Bouncy, bouncy...

Kurusu, put those away already!

Asuna's going to nosebleed to death!

Wait, Kotone-chan.

A-Asuna?

Kotone-chan, I...

I'm...

...inspired to eat 10 bowls of rice!!

Go ahead and drown!

But what's going on here?

They're silicone breasts, cast with Chitose's chest as a mold.

Drawing a little closer...

Every sensation is accurate, including their weight and feeling.

That's not what I was asking!!

You don't understand anything.

W-What?

Did you know? All men in the world are hopelessly fascinated by breasts.

It's simply not a matter of individual preference at all! It's instinct!

Yet they are not reproductive organs, so why do they activate our instincts?

The answer lies in human evolutionary history. Over 4 million years ago, the ancestors of humanity

suddenly went from walking on all fours to walking upright.

Given that modern humans walk upright, there is no need to explain the benefits of doing so.

However, we must understand how mammals are able to discern their mate's readiness for mating.

While there is dissension about the details, virtually all are in agreement that pheromones are involved.

Yes, pheromones! And the strongest pheromones are emitted by the reproductive organs.

During the "all fours" era, the emitters and receptors of pheromones were at the same height.

But when humans began to walk upright, transmission of pheromonal information became difficult.

This cast a long shadow over the continued survival of the species.

This species-level crisis caused a shift in pheromone production to compensate for altered perspectives.

Humans became obsessed with breasts in order to pass along their genes.

Is that story true?

Yeah,

And... we should care because?

at least the part about big boobs

You still don't understand, you simpleton.

With your tiny breasts, you will be unable to win your man,

or even make him look your way.

I never asked for your opinion, you stupid idiot!

I've got enough charms of my own to catch his eye.

Can you really say that, with those attachments?

Whoa, when'd that happen?!

Piece of junk!

T-They did have a resemblance...

An exact likeness.

But to what?

They were about this big...
