I would look forward to this a little bit more if there was more character progression/perversion with popular characters like Sarah and Zero, and now Rue and Lyra.
And other characters like Daisy and Nadia hit a bit breakthrough, but then never moved one inch from that plateau. Daisy sort of became a sadistic nurse instead of a hippie, so I guess that's her niche now, but with Nadia it's a little harder to understand what she's feeling about following this new commander, and the stuff they've been doing.
We've never gotten a strong counterpoint to one of Sarah's early protests, that she isn't going to become one of MC's 'slaves.'
Scarlet, Yuki and Alice (shibari, comic relief and cleanliness) are being handled pretty well I guess. Adding too much to their character might spoil their charm.
Leah, Nyx, Hazel and Jeanne I don't care that much about
