I am so glad that this volume was released because I felt like the ending of the main story left a lot hanging. This volume filled the gap that was left and it is perfect as a conclusion to the story can get. If you have read the books all the way through like I did, then you will know what I am talking about. Even if you have not read the books, the anime even states as much of him showing everyone his world. And it was great to see how things followed up after the class returns to Earth. I don’t know if I really want the rest of the after story because I didn’t particularly enjoy the side stories volume as much as the main story. That doesn’t include Zero which was awesome.
