Why so many upset in the comment??
IMO, nanako just take advantage of this world build, much like lu xia did in her previous2 world...
only nanako take it to the extreme, using her body, while lu xia still deny this (but both play with their prey and they not love them genuinely, so i think it's more like a fake moral compass, but rather just a preference ). And no, i have no sympathy for the guys, for they all trash, so let the predators play with the preys....
if all, i believe this arc is more challenging than previous2 arc where lu xia one sided crush her opponent, here nanako show her resistance and quite agile using her arsenal. I hope to see a tight battle between these two....
