@fsnfanboy where did you get this image can you please show the source? why did you use imgur?
They're unofficial game rips without being 100% verified. I have the collection of them myself but I opted to wait until they were released in a news post on "Girls' Frontline" game site.
I restrained myself from adding an "Error" tag, but the perspectives of some recent official artworks are horrible. Take a closer look and you will realize the stock and the magazine are not aligned at all, as if the mag is bent to the right.
