Pretty much just additional content for people who saw Accel World and wanted a little bit more content after it ended. Episode 1 is sort of forgettable, and doesn't add anything to the overall story. Episode 2, however, actually tells you more about Haru's past and how he became who he is today. The animation quality is pretty much on-par with the show, though episode 2 doesn't really have any high-action fights and is more relaxed. The soundtrack also retains the quality of the show, because it's just the same music. If you liked Accel World and want more, you should at least watch episode 2of this.
