It will be announced in the March issue of Megami Magazine, which will be released on January 30, 2015, that Gochuumon wa Usagi Desu ka? will get a second season. More information will be released at a later time.
Mogami-kun said: For some reason I thought this was already confirmed, must have mistook it for KinMoza or something. Not as huge of a fan of the show as others, but more Sharo and Rize are always nice.
There were 2 announcements that turned out to be fake then this official one.
