To truly appreciate Shinsekai Yori, it must be completed, as only then will the experience be complete, as the show's construction of its world is careful to convey certain messages and hidden meanings throughout the show, allowing viewers to formulate and reformulate key ideas and questions without ever losing sight of the show's world. Additionally, the ending will not be revealed until you see it. Shinsekai Yori was never intended to be more than a single episode series, but after gaining popularity, Oda decided to continue the story via comic books and other media. The first volume of the manga was published in August 2009 by Kodansha with the permission of the author Tatsuo Okada. A second volume was released in January 2010. A twelve-episode anime adaptation produced by Brain's Base was broadcast on TV Tokyo from October 2011 to March 2012. A second season has been announced, which will premiere in April 2017. Shinsekai Yori is one of the most popular anime franchises in Japan today, and the story continues to expand with official materials such as comics and games. However, unlike many other animes that have multiple seasons (or even longer runs), Shinsekai Yori only has one episode, so if you want to see what happens after the end of the show, you'll need to read the manga or look for other projects by Oda.
