The first two episodes are basically a condensed recap of Volume 1, and honestly I prefer the way the Japanese have done it because they cut out the cringiest and most pointless content from that season (goodbye, Jaundice!) to keep things moving. However, this is just to get the show to a point (and probably bring new viewers up to speed) where Studio SHAFT can start their own original storyline, which they do in Episode 3.
