If you were lucky enough to come to Japan before the 19th century, I think you would have been able to meet that creature.

Cold, evil, indescribably weird by any weirdness, its very existence is the embodiment of mystery, the supreme beauty......

I think the earliest record should be mentioned in the ancient document "Hekou Caozi", Dharani and Ashdomini Guanyin blessed the "Guanyin people", guarding their "happiness and well-being" day and night, as their most noble beliefs, commanding them, and receiving the purest offerings of the "Guanyin people". Together, they serve the nine-headed dragon god who lives in the Dragon Palace, and led the kingdom of the sea god to battle the legendary evil spirits of chaos, the Zhuhu people.

This is the oldest document I can find here that I can understand and study, but this is not the case. Should it be said that mythology has its own element of infinite exaggeration? But this is not a myth anymore.

It's fear.

People were forced to write down their history out of fear of that creature.

[Guanyin Zhong], [Shark Man], [Long Cheeked Man], people call them that. I remember meeting them once, when I had just moved my family to Fuyuki City, and one day on a whim, I came to the beach alone, and I didn't think much about the Holy Grail War, about the variables that might exist, and about how to achieve the ultimate mission of the family.

I just bask in the sea breeze quietly, close my eyes and empty my brain.

Then, I heard it.

At first, it was like a frog cooing, through the deep layers of water, and into my ears. The sound grew louder and louder, and finally came out of the water. Literally reverberated in the gloomy night sky. Even if I had a good conceit, I suddenly felt a burst of creepy.

What a weirdness that is.

Hoarse, high-pitched, like the most desperate cries of a human being eaten by bugs. Just hearing the sound that echoed in the air made me feel a tingling in my scalp and I couldn't help myself for a long time.

Then, the guy came out and emerged from the deepest part of the sea.

————————————————————————————————————————————

"At first, it was a slicky liquid fin, and then the fish's head with a vague human face slowly popped out. The two barely eyeballs would never close, like two protruding full moons, so large that they took up a third of the face. The only emotions that can be felt in those eyes are cold and evil, strange thoughts that even the craziest magicians don't have. ”

"Then there's the high back, those bony spikes that reflect the light, and it's terrifying. No one can fail to notice that at the first time. And after being snatched away from the back, I found that on the fat neck, there were two deep parotid glands, trembling slightly. That's probably their respiratory organs. ”

"The body is covered with gray-green scales, and the scales that have just emerged are still stained with gray slime, and occasionally barnacles and the like can be seen attached to the scales. That's a testament to the longevity of those guys, they've lived far too long, some far beyond human imagination. Their 'hands' and 'feet' are long, and I don't know if it's appropriate to call them that, but they have long purples on them, like frogs. ”

It looked at me, then slowly dived into the deep sea as if nothing had happened. It wasn't until an hour later that I realized that I was still standing on the shore, my clothes soaked in cold sweat. Humans are no match for them, and neither are magicians, because they are inherently evil that pollutes the human spirit, and at the slightest glance, their bodies are immobile as if they were being crushed by a heavy object, and they can only be slaughtered. ”

"I really couldn't stand this kind of monster, so I hurried back to my family to find information, my family and I have never encountered such a monster, maybe it's because the sea that Russia and Japan are in contact with is different. And then, I learned everything about them. [Guanyin], [Shark], [Long-cheeked man]...... That's what they're called. I prefer to call them DeepOnes. ”

"I have recorded everything I have seen and heard in this diary, hoping that if one day I die of old age, my descendants, the heirs of the Machiri, will know about it......"

Cold sweat continued to break out on his face, and Shinji Maki trembled and repeated the words in the book. In this book, which is full of bug cards, he finds an article that describes the current situation.

It looks like the diary of an ancestor I have never met, and the language and sentence breaks are the same as those of decades ago. And what is recorded is a strange anecdote that makes people feel absurd when they see it. If it weren't for the fact that he actually "got the power of a magician" and really encountered this scene, Shinji Maki must not have believed all this.

Just now, when he and his friend Emiya Shirou arrived at the foot of the nearest thorn strip, before they could take a good look at the thorns, which were more like "man-made objects" than "plants", those monsters appeared.

Like an upright fish-man, and like an anthropomorphic frog. It's a monster that doesn't seem so terrifying to modern people who have seen various animal anthropomorphisms, but as long as you intersect your gaze, you will feel a heartfelt fear in your heart.

It's like encountering a predator.

Shinji Maki didn't know if Emiya Shirou felt the same way, but when he saw his friend's trembling arm, he knew that Shirou was also sad.

"Hey...... Let's run away. What do you think these guys are not guys we can beat......"

I don't know whose proposal it was, but when the two of them came back to their senses, they were already on the thorns.

Instinctively, they climbed up, but they could still feel the cold gaze on the ground.

After that, it was Shinji who found the record of the monsters called Deep Divers from the book in his hand. Now, the two sat on top of the thorn strip with each other looking at each other, not knowing what to do.

"Hey...... Shinji, if you really can't do it, use your biggest bug. ”

In the end, it was Emiya Shirou who spoke first.

He was referring to the ones summoned by Shinji Kiriri before. The largest of them all, it can carry people everywhere.

Shinji Maki was stunned for a moment, and then showed a slightly embarrassed expression.

"That Shirou...... Sorry, that one can't be summoned yet. ”

"Huh?!"

"It's a matter of the sacrifices consumed."

Shinji Maki smiled bitterly. I've just squandered too many bugs at once, and this magic book is not a "treasure" that can be summoned endlessly and ignore the user's magic power, just a special magic costume. If he summons like this, the first target of those bugs will be Shinji himself.

Emiya Shirou also thought of this, and his eyes, which were still a little bright, instantly dimmed.

"How could it be ......?"

Just when the two of them were relatively speechless, a loud noise was heard in the distance. It was as if some meteorite had fallen to the ground, and a road in the distance seemed to have been cut off by a huge force from outside. Not long after, a voice like the wail of a desperate trapped beast came, accompanied by the sound of a heavy object falling.

"What's that?" Emiya Shirou looked blankly, but there was a building blocking his view, otherwise he could see that just a little farther away, an entire road had been shattered, revealing a dark corridor underground. And in the corridor that they can't see, a "hero" has just "died".

"I don't know, but now it's not surprising that anything is there."

Shinji Maki shrugged.

He didn't want to be like Emiya Shirou, who knew about the magician world at a very young age, and what he could know was really limited.

"Even if it appears, it wouldn't be surprising that there is an army of aliens...... Shirou, where are you looking? When he found that Emiya Shirou didn't look at him, but stared into the distance in amazement, out of curiosity, Shinji Makiri also looked over there.

Then he saw the black tide.

The trend of black "alien shapes".

"That's, what ......"

The Deep Diver still has an icy and evil aesthetic, but the monsters that poured in from the forest ...... The obsessive body is stitched with a human body, and the monsters that push and shove each other with their tentacles are really only disgusting.

And the number of those monsters is not just a dozen or dozen...... Rather, in the thousands! Thousands of monsters!

The closest diver to those monsters looked up in confusion, he had never seen such a thing. Immediately, it received a heavy education, and the tentacles of those beasts outside the human body fell heavily on its body, and its body, which was harder than steel, instantly turned into a lump of minced flesh, exuding the smell of blood. The beasts from outside the human scurried to the top, enveloping the diver's body like flies with carrion.

The shrill roar of the diver could still be heard at first, but then disappeared completely. The encirclement was lifted, and the beasts looked at the more divers with bloodthirsty eyes.

“…… What are those......" Emiya Shirou asked blankly.

After discovering those deep divers who can be called human predators, he had a desperate thought for a moment, but it didn't take long for the form to reverse?

"I don't know, but now it's not surprising that anything is there."

"Since 'weirdos' and 'tentacle monsters' appeared, it's not surprising that 'heroes' and magical girls will appear next...... it! ”

Shinji Maki made a rare burst of foul language.

The building that had just blocked the view was cut off by something, and a dozen stories of tall buildings collapsed to the rear. Fortunately, this is Shenshan Town, not Xindu, and the floors are not too high, otherwise this street will be destroyed with just this moment.

In the smoke of the collapse of the building, a black giant could be vaguely seen wielding a giant blade to slash something, and several points of light appeared in the smoke. And those lights that are clearly not refracted by glass!

That's magic! It's magic, there's a magician there!

A few things rushed out of the smoke...... Wait, that's ......

"No, it's really a magical girl......" Emiya Shirou felt the corners of his mouth twitch a little. At the same time, a sense of familiarity came over me, and although the girls dressed like magical girls only flashed in the smoke, the silver-haired girl seemed to be somewhat familiar......

"Will there be anything else......

With a wooden face, Shinji Maki complained.

……

……

……

Just as that sentence fell, the flower bloomed.

PS: =-= Reasonable...... It's really possible for a deep diver to mess with Fuyuki City. First of all, putting aside the main premise of the type moon, starting purely from the Cthulhu Mythos, the main area of divers' activities is the Pacific Ocean, and the Cthulhu Mythos does mention Japanese deep divers - although I didn't find the book "Wako Kusako", it seems to be mentioned in "Shadows of Innsmouth...... And from the perspective of the moon, well, it's more appropriate to mess with the Cthulhu Mythos. For example, the marshal's Noble Phantasm, which is clearly mentioned.

PS2: Also, be reasonable again...... Although all kinds of clans have strange powers, such as a certain hound that must not be provoked, most of them are not strong in terms of strength alone. For example, deep divers. Although ordinary people will not be able to walk in the past (because they look terrifying), this does not mean that they cannot be killed =-= You know, I don't know how many families are dealt with with crowbars...... One of Yog's sons seems to have been killed by dogs...... So let's add the characteristic of making others mentally polluted to the deep diver for the time being, otherwise it won't be enough to see =-=

In addition, because of the origin [variable], the protagonist is mentally close to these clans and even the old days in some ways, so it is not affected......

PS3: A digression...... Rider Silly is Artoria Pendragon (Christmas Alter). Although the official is indeed a bit of a spoof, but the job introduction has changed clearly =-= But why do some people think that Xiao Mo is a berserker! The cute little Mo is obviously a father-controlled saber! Please don't put it in your head in this regard - don't mention the text of various magic changes and spoofs for the time being.,I still respect the original work very much in PS!
