I rate this one a 10/10 I wish there was another season now, it's been 2 years or more, it was a very good anime and one of the best I have seen. It was very creepy and fear mongering because the children were trapped and couldn't escape. Cannibalism and horror, it is similar to AOT, for lovers of that show. The children are trapped and one of them actually got eaten. It made me curious to read the manga, I didn't want to just stop there. I got a very soft spot for the 3 main characters and it never got boring in this anime.
