I have a feeling episode 6 won't have a lot of action, but I think episoode 7 will be action packed.
This is just my guess, but I think episode 6 will consist mostly of more character development, especially for Alto, Sheryl and Ranka. I have a feeling we could be in for a very emotionally charged scene if Ranka confronts Alto and Sheryl about their kiss.
Also, I think episode 6 will consist of a scene between
(spoiler tag added for those that have not read the manga).
I think that we won’t see the SMS ship launching until near the end of episode 6 and the episode will likely end on a cliffhanger with the SMS forces encountering a large force of Vajra attacking the galaxy fleet.
