If you open the images below directly in a new tab, or copy the url, you can get the full-sized version. Or if you'd prefer to just download the 4 pages directly in a zip file, you can do so here. Big thanks to the anon scanner who made this scanlation possible.
I might write TL notes for this, because there's a number of references to Japanese things (like soccer players), but if you just google the names of things you can find out more. There's nothing explicitely related to Symphogear that needs more explaining, but if you have any questions feel free to post in the comments.
