Why do you equate being and not being human to being evil or not? Not saying you're right or wrong on your appreciation of Kumoko's "alignment", but the being human shouldn't be part of the dichotomy of good vs evil.
I would suspect there's some correlation or simply just war between kingdoms. I don't recall if it was mention if there was an invasion or not and who was invading who. But I think seeing all the humanoids so far on the "demon" side should make us question what is human and what is isn't, and if it's simply an arbitrary descriptor of difference in races.Assuming that she is the humanoid spider demonlord, I wonder how attacking human kingdoms fits into her saving the world-plan.
By this point in time they're pretty much brother and sister, no ifs or buts about it.Also only-in-anime: the dragon girl just like that gives up her freedom for her friend to be able to summon her. ooooookay. This is a typical "good for when we are friends, but bad for when we're no longer friends"-idea, and relationships ARE changing over one's lifetime. I mean, I don't expect this anime to portray it that realistically, so it probably won't become a big problem, but I had to facepalm hard when she shackled herself on a whim like that.
Honestly, I don't see it... but I'm open to anything. With the intrusion of Administrators anything can happen I guess, I just don't see the motivation here particularly when a powerful enemy pretty much destroyed everyone but the one with the Phoenix Down.
All those things aside, I found it funny when she was discussing with her other minds about saving the world that one mentioned delicious food, when all she's been eating has been raw monster guts LOL.
