Not a surprisong development, but this chick needs to be put under Tvtropes morality pet and plot device categories, because she everything about here character revolves around the other 2. Shes pretty much just a plot device and the only way i can see her getting actual developmemt is if she somehow becomes very self aware of whats going on around her and begins losing it. I think the idea of her becoming a new Shigahime is cool and has potential for some interesting conflict if done right.
