The year is 2013 in the city of No. 6, the city that embodies the highest ideals of humankind. Shion has been raised here as a high-ranking elite since the age of two, but on the night of his twelfth birthday his fate is turned upside-down when he meets a boy who calls himself Nezumi.

"Why did I open the window that night? If I had not, I'd never have needed to know what it is like to fight, starve, or suffer in anguish...."

No.6 has been published in Brazil by NewPOP since July 2015.

This is my first review, but I felt entailed to write a review as there is none and this novel was really spectacular in many aspects. I will start off with a warning - if you are not open-minded of male on male relationships then don't read this.

I read it years ago but I was obliged to leave a review as it is definitely my favorite novel.

The anime doesn’t do it justice, so they do want to know more about No.6, it would be good to read the novel.

Characters: The characters are really endearing, each with a very outstanding personality, most have an incredible development.
