If there is, great. If there isn't, even better.
It isn't really much milking it, it's about how it's executed.
it sucks, female chars are lame even though they have the power to solo everyone *cough cough* kaguya *cough cough*
nerfing of powerful enemies so that the plot can continue because the author can't think of anything to take the enemy down.
If there's part 3, i'd like to see the otsutsuki family, how the rabbit goddes came to earth and how her fam split up (the wars they had as well ranging all the way to hashi maddy fight)
so the god arc.
Or at least the next gen when theyre a bit older (a bit boring though as they will have no worthy enemies unless technology becomes more destructive and stronger than ninjutsu and they have to perserve the traditional way of living: ninshu rather than relying on tech/beasts)
