What the goddess said doesn't make sense, even if Jun cursed the world, her reincarnation were always good girls!
All their deaths were horrible If Jun curse had a real impact, then her reincarnations at some point would've turned into "bitches".
But they didn't! Same with the heroes! They were good people who put the mission before their relationship.
I agree with everyone, the true final boss is the goddess!
Anyway, at last we will probably discover what happened to the fourth generation?
