Dude, do you even realize that this is why I was pissed off by the "misplaced tentacle" before?
Can't protect the mother, despite acting instantly the right way...
Clearly Mia, the sister. Little fragile and overaffectionate character, she triggers all protection instinct switches. She's my top, and no other girl is simply able to challenge her leader place, currently - I thought that Lilibet could be a challenger on the beginning, before her spoiled attitude become unquestionable.
Second, Laurie: not so cute, a bit dumb, but is the "lifelong abused victim". Again, protection instinct triggered... Liv is close to Laurie on my personal rating, for the same reasons.
On the other side, I clearly don't like - but without hating them however - the bitchy ones, like Venari or Lilibet, but nothing that can't be resolved with a good taming session - in particular when they are bitchy AND ungrateful. I won't drop them, but I would near always chose the harsh options.
The aggressivity of Iggdra (plus her abs...) is also a turnoff, but no one can deny that she seems loyal until death - so she isn't the last one: she's more a "unpretty loyal friend with benefits" for me, and so isn't badly ranked.
Currently, the last place is really between Venari and Lilibet, with a (dis)advantage to Venari because she clearly hides something - Lilibet is a spoiled and stupid brat, but at least, she's quite honest.
I'm not a huge fan of the mother, surprisingly, because she too hides (too many) things - I hate lies and hiding things, in games and IRL. I hope that she'll soon stop hiding everything - Eva suddenly became more sympathetic to me with the last update cliffhanger, for example.
