Many years ago, after the end of a bloody world war, mankind took shelter in six city-states that were peaceful and perfect... at least on the surface. However, Shion—an elite resident of the city-state No. 6—gained a new perspective on the world he lives in, thanks to a chance encounter with a mysterious boy, Nezumi. Nezumi turned out to be just one of many who lived in the desolate wasteland beyond the walls of the supposed utopia. But despite knowing that the other boy was a fugitive, Shion decided to take him in for the night and protect him, which resulted in drastic consequences: because of his actions, Shion and his mother lost their status as elites and were relocated elsewhere, and the darker side of the city began to make itself known.

Now, a long time after their life-altering first meeting, Shion and Nezumi are finally brought together once again—the former elite and the boy on the run are about to embark on an adventure that will, in time, reveal the shattering secrets of No. 6.

[Written by MAL Rewrite]


No. 6 condenses but largely remains faithful to the the original nine-part light novel series. Changes were made to tone down the amount of violence in the series, in addition to creating an alternate ending.

No. 6 is an anime with some pretty significant flaws, but they don’t really hinder the experience unless you’re looking at it extremely critically or from an artistic point of view. I believe that most fans of sci fi or shounen ai will thoroughly enjoy this regardless of its flaws. Let’s dive in and talk about why!

Story: No. 6 takes place in a post apocalyptic world where all of the remaining citizens have been divided into six city states. The revered No. 6 city state is considered to be the center of the nation and most of the world’s resources go to it. As ...

No.6 has a very good start but then starts to suffer. I don't know what went wrong but it is a shame. I very much enjoyed this but the story and direction just went downhill. I don't usually check manga but I had to with this one.

Love, sacrifice, mystery, acceptance would be the words if I had to describe this show. Orwell 1984 also comes to mind.

Art style and sounds were just fine. It was cute when it needed to be. Sometimes the animation was janky.

Characters Nezumi and Shion save this show for me. I was interested in their stories and how ...

This was such a confusing and disappointing anime. The pacing was too fast and at some point the plot kind of lost me. The ending was horrible, nothing really made sense. I think that the only thing that carries this show is its characters. However, some of them are pretty inconsistent and the most annoying one was Nezumi. Also is it just me or Nezumi and Shion's relationship was a bit toxic at the beginning? Like, whenever Nezumi would get angry on something that Shion did, he would start to yell at Shion and occasionally punch him. I think it got better in the last ...
