When researching Hinamizawa Syndrome, there is something very important that needs to be discussed first.

If something happens to the queen carrier, the village will collapse.

In his article, my grandfather called it the most dangerous situation.

According to my grandfather, if the queen carrier dies,

all the infected persons will go terminal within 48 hours.

This may sound unbelievable at first, but research on the collapse of past local religions and group suicides around the world should indicate that there's some truth to it.

Among all the mysterious incidents around the world, there are some that were caused by parasites controlling entire communities, very similar to Hinamizawa Syndrome.

Grandfather picked a few cases that are very similar to the syndrome and investigated them.

As a result, he confirmed multiple cases of entire communities losing their minds after the death of a religious leader or founder, and finally annihilating themselves.

He stated that, on average, it happened within 48 hours.

It's clear that infected people are affected by the queen carrier, and the condition of the queen carrier is, in fact, affecting the entire village.

Our statistics already proved that on weeks Rika felt sick and visited the clinic, we saw an exceptionally high number of visitors.

Rika being sick with a simple cold had a massive impact.

If something particularly bad happened to her, we'd be facing a serious situation within 48 hours.

That's why the Irie Institute has to protect Rika Furude, the queen carrier. It's the most important mission of the Hinamizawa Syndrome research project.

She's already agreed to help us in our research, but we have to be very careful not to put her in any danger.

Also, we have to protect her from anyone who would try to harm her.

Her life is equal to the lives of two thousand villagers.

But...

what if something happens to her by accident?

The Irie Institute must prepare for that situation.

That's why I worked on the draft of an emergency manual when the Irie Institute was first established.

It's a precaution in case the queen carrier dies, or if infected people show acute symptoms due to the death of the queen carrier.

This is an emergency procedure which must be followed within 48 hours of the mass occurrence of the acute symptoms.

......The final measure is to prevent the damage from spreading to nearby areas.

The plan uses gas, making it look like a natural disaster.

My client, the Alphabet Project, took the responsibility of working out the details of the plan.

They are used to dealing with things like nuclear and biological weapons, so they ended up being such a big help.

There's no way I could have come up with a plan on my own to execute two thousand villagers.

Through a dummy company, the Ground SDF has secured a closed quarry in the Yagouchi region, upstream of Hinamizawa.

It's to be the secret storage base for the equipment we'd use in that operation.

Equipment that sprays deadly gas that kills people as if they were falling asleep is stored here. In the case of an emergency, a special unit of the Ground SDF is to use this equipment to destroy the village.

However, preparing for the execution of the villagers itself is politically dangerous.

So, if I'm going to insist on them getting the equipment ready, I have to make them understand how dangerous Hinamizawa Syndrome is, and also how urgent the need is to have a contingency plan.

I have to prove the need for the plan by showing them enough data.

So the files my grandfather kept intact come in quite handy.

When the clients read my grandfather's articles about the syndrome,

they were surprised to see how catastrophic things could be in the worst-case scenario.

"......In other words, if something happens to this girl, the queen carrier, all two thousand of the villagers will become deranged. Is that what you're saying?"

"Yes.

There have been several cases similar to Hinamizawa Syndrome where group suicides took place.

In the case of the syndrome, we can easily expect extreme defensive behavior which results from deep paranoia. The result may affect all two thousand plus carriers.

From there on, we may face abnormal situations involving lawless violence and bizarre religious despondence.

We must be ready to face such a situation by having a contingency plan, otherwise we'll draw attention from the rest of the world.

We have to remember that we only have 48 hours to respond once it happens."

"...Are you saying that if it happens there's nothing anyone can do?"

"Can't you treat everyone within 48 hours?"

"That'll be impossible.

We don't even have a cure, and the research center isn't capable of taking in all the villagers."

"...How frightening to realize such a disease actually exists.

The world is full of mysteries."

"Constant vigilance against worst-case scenarios supports our national defense, and is one of the ideas behind the Alphabet Project.

Besides, our goal is not to use the plan, but it's vital to be prepared."

"Indeed.

Precisely as you say.

I'd still like to look into strengthening the rules of approval authority behind applying the plan, but I understand the necessity to prepare our response for a worst-case scenario."

"Let's have the urban suppression research team run a simulation of the Hinamizawa suppression operation in the region.

I think we should get it going as soon as possible."

"It's possible that the queen carrier girl may be hit by a car and be killed at any moment.

Thank you, Major Takano.

We have further questions, so you can sit down."

Thanks to a push from one of my backers, things were decided without too much of a problem.

It took me almost all day to explain it to them, but it only took a short time to come to a decision.

Nobody criticized, ridiculed, or tried to reject my grandfather's articles out of hand.

...In the files they're all reading today...

...are the very same, shameful articles those haughty authorities left their footprints on as they trampled them and my grandfather's heart.

But they aren't ridiculing the articles.

They are reading what was once rejected.

It's nothing big, at a glance, but in this moment, my grandfather's research is being recognized for the first time.

My heart is filled with satisfaction to see people discussing amongst each other while pointing to my grandfather's files and raising them as proof.

...I've worked so hard for this day.

Grandpa in Heaven... can you see this?
