This is a relaxing episode with added fan service that provides a welcome break from the intense action. As hinted at the end of the previous episode, Hyuga takes on the role of both the administrator and mechanic of Gunzou's stronghold, which is quite surprising considering their "explosive" past. The episode also explores Gunzou's ideals regarding what should happen once their mission is complete. In my opinion, his outlook is naive, especially considering everything he experienced in the previous episode. Given humanity's actions on the past episode, it doesn't seem like people are ready for the kind of future he hopes to achieve. P.S. The change of visuals in the ED was pretty amusing 😆 and nope, this isn't a filler episode
