A distorted, endlessly black darkness.

The location where the dark swallowed everything and took everything from us has become known as the Lightless Realm.
Born there, as if they were mirror images of the despair and chaos humans felt, were aberrations.

They were called Admonitions.

An investigation of the Lightless Realm that eats away at the human psyche. Can a group of eight boys and girls gathered in an effort to combat the Admonitions see the light of the future beyond the Lightless Realm, while their past destinies and dangerous present intertwine in a complicated web?

First of all, I'd like to say that the key to truly enjoying M3 is having an interest in a series that not only showcases sci-fi/fantasy elements but also has the tendency to go deep into the characters' psyche, exploring their personalities and how they came to be like that. I'd go beyond that and say it's not so much about the story but the journey these people go through and the very simple yet effective and truthful message it’s trying to convey about what connecting with others truly means.

Story 8/10

It starts really slow and sligthly confusing. I'd say this is the main downfall read more

Ok, so I've just finish watching this 24 episode anime and quite frankly I have mixed feelings about it, so I'm gonna cut to the chase and just present my ratings for this anime:

Story: Decent 4.

The problem with the story was that it has too much in it that the plot and the story-line itself wasn't easily understood, especially when it has a mixture of sci-fi mixed with supernatural, in my opinion the two genres are like oil and water that don't mix, it also has a combinations of "SOMEWHATS" and SOME SORTS"and I do mean "SOMEWHATS." First of all there is that somewhat of read more

I do not know why people dislike this anime, or the amount of hate I get from people watching this, maybe because this is pretty slow-paced, so most watchers didn't continue to bother watching this series. First of all I'd like to say that watching this anime episode by episode will only bore us, and that's why I think most people dropped this show. Maybe they don't find it appealing enough, or because of the slow start, forgettable characters, and the mediocre animation. So I advise everybody who plans to watch this anime : WATCH THIS STRAIGHT.

The story is good, the synopsis explains that read more

Communication. Understanding. Connection. All things we as humans struggle with. To truly know another person is difficult on its own; some would say impossible entirely. That, however, doesn’t stop us from trying, no matter the pain. Pain that births from failed attempts of understanding, thinking you know someone but in truth do not. Sometimes, trying to connect to another is more painful and can hurt more than trying to cause them misery. But who hurts more: the person who tried and failed, or the person on the receiving end? Can comprehension of others truly be had if we are separate beings? And should we even read more
