"Human strength is just too weak, and do you really think they would use the little navy they have left for Charles? Heroes are just a topic of conversation."
"It takes an apocalyptic atmosphere to truly unite people, to push together in one direction. Gone is the overwhelming oppression that once united them; now they start having their own hidden agendas. Didn't you see how close those guys came to fighting each other over the distribution of ownerless islands?"
"They become like that over trivial benefits, do you expect them to work together to save Charles? Don't be naive, my dear daughter. It's better to rely on oneself than to rely on either Heaven or Earth."
