I am really glad Soryo moved from shoujo to psychological thriller, because she's so good at it! Also, the mix of psychological thriller and shoujo in Mars was somewhat disturbing (well, uh, on another level than the straight psychological thriller side).
I was just a smidge disappointed to see Mine and Shuro kissing and having sex, just because I feel it's so rare to have a romantically unattached female character (even outside of manga, sadly). On the other hand, most of me liked it because it was strange and a little disturbing and not very romantic at all. Also, I continue to love how Mine thinks about these things.
I laughed hysterically at the one-eyed dog, because dude! What is with manga and missing eyes? On its own, it's not cracktastic at all, but I am twelve like that.
I was intrigued by Yuri and her mother's relationship, and Soryo did a good job of portraying the complexities in it and the wrongness even as she acknowledged the mother's abuse from her own parents. I really liked the mother's conversations with Mine and how Soryo didn't let Mine off the hook for prying, even if it was to help Yuri. Also, LOVE that Mine corrects herself -- she can't save Yuri, but she can try to help. I do think Mine did the right thing, but I like that it wasn't a straightforward event, that Soryo dealt with the mother's complicated feelings as well. And it was particularly interesting watching Mine wrestle with her position as privileged (or relatively so), and I like that Kimiko's ghost was hanging over the entire scene as well.
And hey! Shuro is not as amoral anymore! Even though he still wiped the memories of everyone in Mine's lab, at least he is thinking more about using his powers.
