The only winter anime that caught my eyes is Akikan. Akikan first started off as a light novel that was written by Riku Ranjō. The first novel was released on May 24, 2007, and as of April 25, 2008, five volumes have been published. Then on October 18, 2008 the first manga was adapted in Ultra Jump.
The story revolves around a typical high school boy named Kakeru Daichi and the can of melon juice soda that he bought from a vending machine. The can suddenly transforms into a beautiful but standoffish girl that Kakeru nicknames “Melon,” and more “Akikan” (”empty can”) girls appear. However, Akikan girls need to be infused with carbon dioxide from kissing to survive
here is an preview of it.
