I had a dream.

It is a dream of memory three years ago.

Back when the rainy season had dawned and the summer heat in the northeast was getting tough. It was just before I moved into another world with Reesha and the others.

"Demon Knife"?

"Yamato, have you never seen it? That shrine in the back mountain of the main house, the spiritual hole behind it... that's where the" Spirit of the Demon Knife ”appears"

I heard such strange rumors from relatives gathered when there was law.

It is a monstrous tale of a shrine at the foot (foot) of a mountain in the main house where my parents are located. Anything was about a Japanese knife made in the Warring States era coming out as a ghost with that resentment.

A demonic knife appears only during the summer basin period. It is such a monstrous conversation transmitted to the main house.

Several of my own relatives and cousins said they had experienced it before.

(Just taking a basin break...)

I, a social worker, have a summer vacation with bon break added starting next week. I also planned to go around the mountain where the shrine is located on a mountain climb.

(ghosts and other unscientific. but......)

I do not believe in strange phenomena or ghosts.

But somehow I decided to go check on the rumors of the "demon knife” that bothered me.

Then a few days later, the season of the basin arrives.

After a long summer break of two weeks at the company, I stopped at a shrine where demon swords emerged as planned.

"The spiritual hole goes up this staircase, behind the mountains. Take care, customers."

Upon hearing the description of the shrine's palace chief (Guji), I ascend the stairs in the woods.

The sound of the cicada sounded loud, playing a short northern summer.

Sometimes it's the time of the basin. There's no sign of worship, and I go up the stone stairs where the cockerels grow by myself.

When you climb up a long staircase sandwiched by such a forest, your vision opens just a little to the side.

"Feeding (like) a vault? That's a lot of people."

There was a neat line of over hundreds of vaults there.

Earlier stories of the palace chief indicate that this provides for lives lost by wars, plagues, etc., in an ancient and dedicated vault.

Not one face, though so many, was the same, and the thoughts of those who made and served were caged.

"I miss you. Now you have a cousin who cried."

I remember when I visited this shrine in the past with relatives.

I saw a bunch of creepy atmospheric vaults and I got scared, and I was crying about my cousin. I don't believe in paranormal things at all, and I was wondering what I was afraid of at the time.

"Well, here it is"

While I was thinking. Reach the destination location.

"Is this the spirit hole? There are rumors of the spirit of an example demon sword."

What arrived was a small cave in the middle of the mountain.

A horizontal hole where only one adult can pass continues to the back in the dim. Although not maintained for tourism, I have long heard that it is a spiritual place visited by worshippers.

"I think it's superstitious, but why don't you come in?"

I decide to light the back with the flashlight I brought into the cave.

There are no other signs of people inside or around.

Strangely enough, the cicada chirping also stopped perfectly, making it a creepy quiet space.

"Now, will there be ghosts or snakes..."

I don't believe in psychic phenomena at all.

But I feel "something” that I can't speak of, and I never move on to the cave.

And as I was proceeding through the cave in the horizontal cave, I reached the penetration.

"Is this the obsession point?"

The destination we reached was the end of the cave.

Unlike the narrow passages so far, the ceiling is suddenly high and there is about ten tatami of space.

Out of nowhere is the sound of groundwater flowing, forming a quiet yet strange space.

"Is this Shintoi?"

At the far back of the hall was a pedestal with people's hands on it. The Miyagi story says that this is where offerings used to be dedicated here.

Now it is only scraped with nothing and the stone table is placed. My own relatives said it was around this stone table that I saw the spirit of the demon knife.

"Is there still a ghost of a demon knife?"

Check all the way through the cave with a flashlight. But there is no shadow like the demon knife I was hearing about.

"You didn't look like me."

I am a realist who does not believe in strange spiritual phenomena at all.

Anyway, I was concerned about rumors about the spirit of the demon knife I heard about being a relative, and I've gotten to this point.

I can't explain it well in words, but when I heard the rumor, I felt something. Destiny or intuition?

But this time it would have come off.

"Now, let's go back to the inn."

My original purpose is a summer vacation across the basin and a mountain tour I used.

I was going to use the famous mountain above this spiritual hole as a starting point to indulge in nature while spending the night in the mountains sometime.

This is the survival camp you call it, and the itinerary is pretty hard. Let's say we get back to our accommodation tonight before that departure.

"Well...... hmm?

It was then.

I'm trying to get to the exit corridor, and I sense something.

(What are the signs of this scourge...)

When I feel signs of zombies and disgust on my spine, I send a warning signal all over my body.

Activate the five senses fully to be alert in the dim cave just illuminated by a flashlight.

(Bear or... person... no, you're not...)

When it comes to dangers that are realistically behind mountains like this, there are only people or wild beasts.

But neither of these evil signs were true.

(This is... what...)

Raised by my parents, who call themselves adventurers, I was brought around in nature all over the world from an early age.

There have been secret tours out of common sense, but I have only a little more experience than normal.

Those who emit this dangerous sign to compare were not men or carnivores.

Concentrate on the five senses and explore the invisible "something”.

And I notice some position.

"It's you. This sign… who is the killer?"

I ask the "shadow” at the end of my gaze.

It was the entrance and exit of the passage leading to the exit of the cave.

(Is this the rumored demon knife...)

Soon there was a Japanese knife in that place where no one was supposed to have been.

A knife with a stunning blade print, but a demon knife that emits demonic light floats in the air.

And as I react to my voice, the suspicious light gradually grows and forms a shadow.

(man... no samurai... here it is...)

Calmly analyze the sudden appearance of the shadow.

It was an incredible phenomenon, but it is true that it is actually happening in front of us.

It was one samurai who appeared.

I was trapped in a cave by a samurai armed with a demon knife and pitch-black armor.

So the dream of memory three years ago awakens.

"Ugh..."

I wake up from a dream and I look around. Focus your five senses to maximize your level of alert.

Because I had no idea what I was doing.

"... where... where...?

I'm not a bad sleeper.

Somehow my parents, who call themselves adventurers, took me to sleep in secret borders all over the world from an early age.

♪ I'll leave half my consciousness when I'm asleep ♪

It was a habit stained on me to survive in secrecy, and it was no different now that I grew up.

"Why am I in these woods..."

But now he had no memory of him before he went to bed. I had my name and previous memories of my life.

Only the memory of this “few days” had slipped through. I can deduce from the outdoor clothing and large backpacks I wear that I was on my way up the mountain.

(No... I can't remember...)

Trying to remember these last few days, I get a severe headache.

Maybe he lost consciousness and hit him hard in the head. But I don't see any trauma anywhere in my body.

"I'm going back anyway..."

Do one thing to go home to your own house to sort things out. homecoming instinct as an animal and choose to return to the house (home).

(In this mountain... and I'm somewhere...)

The thought of getting my hair pulled back becomes stronger as I descend the mountain.

I don't know why, but it's like I'm forgetting something very important... such a negativity of oblivion and regret.

(Something very important...)

Even on the way down the mountain, it doesn't bring back memories. And I went back to my house.

Safely return home in your own car that was stopped in the parking lot at the foot (foot).

The driving skills, the directions back home, and the memories around here were clear. Again, the only thing I don't remember in the last few days is the memory.

(Well... there's nothing particularly strange about the house...)

Pull over to the parking lot in front of the house and check the perimeter. There was nothing unusual about it, it was a normal home.

"I'm home."

Enter the front door and greet the back.

I am the only one living in this whole house now. But it's been a habit since I was a young girl, and just saying hello has never been indispensable.

Education such as greetings and courtesies were strict parents. Other than that, some unusual survival technology was knocked in.

"Well, thanks to its survival and protective techniques, I survived“ over there "..."

He was a self-proclaimed adventurer and free-running parent, but he appreciates the area.

I remember my parents who haven't even seen their faces for the past six months and laugh bitterly. Now only two couples should have challenged the climb of the highest mountain range in the world.

(Well... "over there” means... where...?

Doubts arise as I speak for myself.

Obviously not Japanese or foreign, the word "over there” denotes another place. It could be a clue to how long your memory has been gone.

"No... I can't remember..."

I try to remember, I get another severe headache. It was falling out like something forced me to scrape it off just there.

(Hmm...?

It was then.

I take off my shoes in the front door. I feel strange.

"Knock..."

At the same time, I have severe pain in my right ankle. The invisible thin wire is tightening.

(Wire trap…)

The wire was planted on the front door mat.

But by the time I realized it, it was already late. Lifted with tremendous force as it is, it builds upside down in the blowout doorway to the second floor.

I overlooked the existence of a trap due to an unconsciously severe headache.

(Hunting traps for beasts... and powerful guys...)

The trap was for capture using Teco's recoil.

Having instantly understood the situation, I slash off the ankle wire with a knife for climbing. And at the same time, we use recoil to jump on the second floor of the blowout.

"Well... let me explain..."

Upstairs, in the blowout hallway, I found the killer who set this clever trap. Order an explanation of the situation by pointing the blade tip of the knife.

"You raised your arm..."

A big, hairy man comes surrendering with his hands up. The opponent is no longer willing to resist.

"And this dad will be delighted to see my child grow up! Gahaha! Hey, it's your mother!

"Yep... you've grown splendidly, mountain man (Yamato)"

One woman shows up from behind the big man. The aptitude was ordinary housewives, but a brilliant covert technique.

"Totally husband and wife, what are you doing... anyway, welcome home, Oyaji, and your mother too"

That was the first reunion in six months.

My parents, who were on a journey to the highest mountain ranges in the world, were returning home first.
