I've actually seen that one scan I posted there before, with Tatsumi and Mine in a school setting, there's also another page with Lubbock. But I had my doubts about its origins. There are apparently even more of such extras. There's at least one crossover with some other manga that has Night Raid's female members wearing neko ears, and a bikini special AgK Zero crossover as well. Though, they only have like two pages each.

We could make a list of those if we had more to work with, but I've only seen them scattered around the Internet untranslated.
