At the end of the 26th and last episode of Little Busters! (リトルバスターズ!) a preview of Little Busters! ~Refrain~. There have been many rumors about a second season and it is apparently Refrain. Refrain is a scenario that is unlocked in the Little Busters visual novel when all the 6 herione scenarios are completed. Sadly, the preview did not give further details to when Little Busters! ~Refrain~ will air. The official twitter account for the show has asked the fans to wait a little longer for details. The official website is now streaming the teaser as well but without any details as well. I predict this to air in Fall 2013 or Winter 2014.
Little Busters (リトルバスターズ!) aired from October 6, 2012 to April 6, 2013. An OVA will be airing on August 28, 2013. Honestly, I don’t really like the show and I have been unable to finish it due to me finding it really boring. I am going to finish it though before Refrain starts, fans have stated that this scenario happens to be the true Little Busters! Congrats on the TV adaptation Little Busters! fans.
