There's no way Ishibumi would reduce it for the entire rest of the series. Just for the build-up and climax of the war against Qlippoth. Volumes 10-12 were the same thing for the Hero-Faction (albeit less intense than this and fewer volumes).

If story arc 5 can have a plot even more intense than this, I will be extremely impressed.
