Getting the manga right was already a Herculean task by the first chapter; introducing 72 + characters when there's no shortage of award winning, fan favorite stories with barely six named ones. Now it seems the author has run out of archetypes to base the remaining demons on and decided buy time basing entire arches on petty grievances between quaternary characters. "Conflicts" in outlandish scenarios that plain and simply wreck any semblance of logic behind the inner workings of the world, that for the matter, already had reality altering, pocket dimension creating demons to begin with, so it's not like the laws of physics were holding him back from devising the ecchi scenario of his dreams.
