Interesting story so far. The blend of characters is pretty unique, and I already see a lot of potential here even though it's just getting started.
I've never read anything by this author before, but he seems to have some popular long-running series already, so I hope this one also has a long run.
What they're doing to Hana reminds me of that girl from the moon base in The Silent Sea. I wonder if it'll have the same grand implications as that show, or mostly stay small-scale like it is so far.
