The final arc is here.
Let's talk firstly on the format of this arc, as it will be a bit different from the previous ones. Rather than an intermission at the end, bits and parts of side content will be interwoven between each chapter. This does mean you won't be watching everything back to back, but it does mean that you'll be able to get a full experience in one sitting; you won't have to go back and see a bunch of extra stuff after finishing the arc unless you want to.
Also, they ran out of money for voice acting. Expect most of the rest of this experience to be using Japanese voice acting only (with a few exceptions).
So... let's head into the depths of The Cage.
