Review Detail of Draj in Annihilation Maker DXD

chapter 160, story progression is worst, boring, the release rate is slow, dragged out story, at this point I don't even know who is the MC, this Kazuma is annoying even after receiving help remained ungrateful, he's received punishment for his uncontrollable tongue yet he still continues such behavior, if I can change the ratings now I wound give this 1 star just for the sake of earlier chaps and MC, 43(till ch160) chapters without much of MC involvement
