User blog comment:B214/Volume 22 spoilers/@comment-9595671-20160814045836

I just realized I never bothered to think about this cause the spoilers for this volume and the previos never mentioned it, but has the Khaos Brigade finally been defeated with the death of Rizevim and trapping/sealing of Trihexa?

I'd like to know for sure because they've been the villains for all but the first three volumes and it kinda feels weird for me to think they won't be in the last arc of DxD.
