I told you Sir Nickolas (You know who you are my friend). I told you this would happen sooner or later. I am (almost always) right!
It was announced at the “Stage of Missions” event that Princess Principal would be getting a sequel in 2019. Then it was announced it would be presented in a six-part movie format. It would seem that the new thing when it comes to some anime continuations is the following: “If you can’t get a new TV season then how about a multi-part cinematic feature?”
Girls und Panzer got a similar deal with their “final” season. As usual when it comes to anime movies the sole nuisance is waiting for “dem subs”. Peeps who have no such issue are the lucky ones. So for now the news articles say the movies will air in 2019. Maybe it’ll be similar to the Washio Sumi movies and they’ll air back to back throughout the year. We’ll see. Whether the movies will fill in the gaps of cases that weren’t shown during the first season or simply continue where S1 left off and not reference those cases I’m ready for more gay spy action! Hopefully the writers listened to the fan reactions and will do the right thing. Thanks to Pink Raichu they know.
