We're going to be suffering a lack of Waka-combi chapters for a while here. The kid heroes get more established as mains, Ozaki chapters are basically just there as quick way to establish who's dying in a rapid succession of deaths, and Seishin chapters have more to do with his writing and Sunako, but they'll get back together again around the end of chapter 9. Hope you'll stick it out until then, even as less and less material is all-new!
