Yes, Grace could have been silver-haired!
Also, yes I foreignizationally translated “金髪” as “gold hair”. Deal with it.
Edit: A couple more things:
1. I won't get around to them immediately, but there are 7 remaining main chapters to translate (11 & 13–18).
2. If you're wondering why this was initially Ch. 7.5 but is now 6.5, it's because I discovered that Mistakes Were Made totally fucked up the numbering for this series. I've already made the report, but just a heads up.
