Wait so this chapter reveals that the hero party fought a war because monsters, which are not demons but reside in their realm, keep killing human? Then had as a condition for the losing Demon Lord that the demons had to train all monsters to not harm humans. Am I understanding this right? They held the demons responsible for the actions of WILD ANIMALS then forced them to train all wild animals in perpetuity?
These dickheads are supposed to be heroic? Even children aren't that brainless.
