The specials are very well animated in the same style as the main anime, and for short specials they look and sound really great. Specials are made of two parts, first there are the 1-minute long episodes from the POV of a person on-board the Ryvius and the second part consists of 3-minute long episodes adding to the backstories of other characters from the show.
I was really surprised by the high quality of these specials, but because of their shortness, you can't really get anything in-depth from them. You should watch this if you enjoyed the main show, they add some backstory to the show's characters.
