Thanks to one of my aniki's who posted a photo to a secret Yuri group in Facebook, it revealed a screenshot to a tweet from The Official Yuru Yuri Twitter account that a Season 3 is confirmed. No dates or official released date has been announced. This is another treat for Yuru Yuri fans and of course to the entire Yuri-loving fans. If you have not watched the anime yet, then I suggest you must do now! It's a recommendation!
Below is a screenshot of the said tweet and click here for the official tweet link
