The official Twitter account for the publisher confirmed that Volume 14 of the series will be the final release for the series. It's scheduled to debut November 19th in Japan, one year after the last volume, so it won't be long before details about how the series ends make their way to the public!
But that won't be the end of the franchise as a new season of My Teen Romantic Comedy SNAFU is currently being planned for a release sometime next year. Although many details of the new season are still being kept under wraps for the moment, Season 3 will be produced by Studio feel., the studio behind the second season. So while the original light novel series will come to an end, the franchise will live on in other ways!
