The action scenes in this manga are top tier. They're a lot more detailed and their choreography is a lot better than some traditional shonen manga that are, nominally, more explicitly about fighting than a silly yuri manga about cute girls being cupids, but with guns.
Also, for some reason, this chapter reminded me of the old girls-with-guns animes, like Noir. It's not so much the specifics of the scene, but the overall feel of a story about cute girls doing violent things with guns and the actual attention to detail used to portray and contextualize the violence.
