According to the Tweet, the second season of TV Anime Chuunibyo demo Koi ga Shitai! (中二病でも恋がしたい！～) will be aired in
next Spring this Winter, starting from April 2014 January 2014. We’ve talked about the rumor a while ago and soon after which the confirmation came. And when we are all thrilled by the news, one month later the movie announcement of the series was made and will be premiered in September 14 in Japan. Though this is not an official confirmation, it does gives us a hint and is more or less something that we could celebrate. Will update with the official announcement in this post. Bookmark and stay tuned.
Update: It appears that the second season will be aired in January 2014 instead of April. I made a mistake in translating the correct date. Source also confirmed.
