WARNING: do not read if don't want to be spoiled, if you are easily scared, or are claustrophobic.
- Soon after the holes in the mountainside are discovered, Nakagaki slides into one that's exactly his shape. In a nightmare Owaki has, he's Nakagaki and the hole is slightly deformed deep inside the mountain due to the earthquake and he cannot proceed. The last shot of the nightmare is him hundreds of meters inside the hole, completely unable to move, in absolute darkness, screaming for help that will never come. And the worst part? It's presumed that he died of dehydration as the result. And considering what happens to those who do manage to proceed, he would be one of the lucky ones.
- There are also child-sized holes on the fault...
- It's likely that his hole wasn't misshapen by the earthquake, which brings up an even more horrifying possibility. Each of the tunnels probably changes slowly, causing the person descending through it to feel enormous pain as they're compelled to move forward by claustrophobic panic, desperately seeking an exit that they're not sure is even there. For the tunnels to function, it has to be impossible for the people moving through them to die or retreat, so when they get stuck, they just have to force themselves to go deeper anyway.
- Not only do the holes have hypnotic properties, they're also tailor-made for a certain person. Those who see their hole, even for a brief second, become immediately obsessed with finding it and going in, even when they know it will most likely mean their demise. Even worse, by showing images of the fault all across the world thanks to TV, the news reporters might have inadvertently caused thousands of people to go there.
- Its effects also include giving the protagonist nightmares, but are those actually nightmares, or are the events Owaki sees in them another form of telepathic message from the fault?
- At one point, Owaki seems to have found a solution for the problem: filling the holes with stones to prevent people from going in. Unfortunately, that doesn't work.
- Let's just say, if you suffer from claustrophobia, this comic is not very pleasing. And if you don't suffer it, this might as well cause you to. Because guess what? The holes get smaller and smaller as you go deeper.
- Once all is said and done, the story never offers a clear explanation for how the holes ever came to be or why they have their hypnotic powers. Is Amigara possessed? Were those holes man-made or not? If they were, who did them and how did it knew the shape of those who would come there? Not knowing can sometimes make a thing scarier.
- The ending of the story and what happens to those who entered the holes. Let's just say that what happens after you go all the way isn't pretty: as you progress deeper, the holes, which start off matching the person's body perfectly, start to gradually become more and more twisted, causing the person's body to be similarly deformed as they're forced to advance into a gap they shouldn't be able to fit into. By the time they reach the other side of the mountain, their body has become completely squashed and contorted, barely even looking human anymore
◊. You can't help but feel bad for the poor bastard.
