Hetalia: The World Twinkle
Story
After we added the first three seasons, you didn’t really think that we were going to let the brand new season pass us by did you? Of course not! In the new season we’ll be seeing all of our favorite countries return to teach us more about history in their own unique way!
Why You Should Care
Hetalia is a series that is not going to go away quietly or vanish into the night. It has more than proven that it is here to stay and fans of the series will be forever grateful for that!
Based on my research it seems that the cast and crew from Hetalia The Beautiful World will be returning which includes Studio DEEN producing the animation, Hiroshi Watanabe as director and Kazuyuki Fudeyasu taking care of series composition.
