Harvest December is a visual novel that was originally a PC game, which was then ported to the 3DS, and now that 3DS version is getting a Western localization, thanks to a collaboration between Circle Entertainment and Flyhigh Works.
The VN consists of 13 chapters, which were released monthly in Japan for just 100 yen each. However, the story’s likely to come in its entirety to the West, as that kind of a setup would be a lot riskier here.
As localization has just begun, it will be a while yet until we get the visual novel. We’ll keep you updated. In the meantime, you can get an idea of Harvest December through its Japanese 3DS trailer, featured at the top.
