Thanks for the chapter!
Hirakawa was just jealous because she couldn't create a new magic herself. As an engineer herself, I'm sure she doesn't consider all those responsibility stuff.
Some notes about the translation:
Pg 7: "young magician born on the" <-- incomplete sentence
Pg 10: top left bubble is not in English
Pg 22: top left bubble feels unclear. After checking the raw, this is what I think it should say: "Or perhaps conventional weapon manufacturers want to prevent the decline of sales from being replaced by magic?"
