If anything it went more into the shiny shounen art, OP has a lot going on in some chapters and I still find it easy to follow that, this one is just really bad with it frames.
This whole gangbanging HQ seemed really rushed though, as she threw out all the Apostles, introduced Akuma disciples and the other black dark corps whatever and threw them into one battlefield, if they were spread out and not taken to the one place it would've been better (saying that, there are quite a lot of people that are still not at HQ and around with akuma disciples / apostles) but having the main antagonist, his little army, a new little super soldier and the main protagonist and everyone half dead is a little off, if I do say so myself.
