sorry but that's about Japan, they have veery different culture related to their respect to society layers. I think author wanted to show how narrow minded they can be due to that trait so as the caracter's growth 

People should be more understanding I guess

didn't you thank that it's the whole point of the manga? Wteir story IS based on this conflict 

Everyone complaining about it and then if there is no explanation and redemption of the caracters everyone's still complaining

That a great arc and its important to the plot

8 princess

her hoe sister

if i'm not mistaken she's daughter of Aisha's older brother from previous life

the one who ruled the empire 

she's not a mother 

she's just a neihbor cafe's owner 

I thought control isn't forth knits of apocalypse 
it's hunger, war, famine and death tho
