Although I can't give detailed and accurate spoilers and hope someone else gives it. From what I have gathered, Cyan's sister forms a contract with the gods and becomes the new hero I think. And Eschel(is that the little shit's name?) becomes a fake hero and I believe he dies after the God who chose him became disappointed with him and abandons/punishes him. This happens after the war with the demons is dissolved. And the culprit of the war turns out to be Eschel's mother who turns out to be a witch who cast a mind control curse on something(a pendent maybe?) and Eschel who gave the cursed object to the demon king. The demon king does find out and punishes Eschel's mother. Oh and Cyan's dad also dies during the war against the demons. Again it's not very detailed but this is for those who can't wait for the shitty ass family members' deaths. Again this is not accurate.
