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

If there is one thing that drived me trough this anime it was it´s deep and intresting story, truly one very unique and for me the first of it´s kind.
Its backstory and premise is fantastic although unfortunatly the characters of the show does now support and help the story very much, except for Akashi and the crazy researcher wich name i forgot. The characters just feels like very onesided paths that you walk without any change in the way you walk.
They felt dull, boring and sometimes it felt like the atmosphere around certain characters where just outright emotionless or depressed.
The action sequences is very read more

Anime: Neon Genesis Evangelion
What M3 does Neon Genesis Evangelion did before it and better. That being said, M3 has more characters and group dynamics, which is a worthy addition, while NGE was about loneliness, abandonment, and how they shape people and their choices.

On the other hand, while NGE's characterization is better and there are proportionally more adults, there are few "likeable" characters; M3 is a more typical genre anime with a larger cast with plenty of cliches which makes it easier to find someone to like. If this is an essential element for enjoying anime, Neon Genesis Evangelion might not be a rec for you.

Group of kids forced to pilot a mecha to fight some unconventional enemy, the enemy in both anime holds darker secret behind them.

Anime: Shinsekai yori
They are both different from each other but somehow they both give off the same vibe and eerie atmosphere. One is set a thousand years in the future and the other in the present and the latest is mecha.

Both have a mysterious air about them and the characters in both are a group of students either friends or acquaintances.

I can't help but think that M3: sono kuroki Hagane will have a twist just like Shinsekai Yori did.

Anime: Innocent Venus
Both have psychological and dark undertones, mechs powered by humans and technology progressing by human experimentations. Honestly, identical shows.

Both have some sort of infectious virus that is destroying humanity.
One fights with mechs
The other fights with lolis :D

Anime: Sidonia no Kishi
> Both have some kind of weapon to eliminate enemies. ( Spears / Stakes )
> Enemies have to be hit in a specific place to be annihilated.
> Both uses 3D CGI in mechas.

They give off that "eerie" feeling.
