User blog comment:Goddess of Despair/RWBY and it's connection to the supernatural/@comment-6500074-20130304025706

Interesting proposal. However, I don't think it is a plausible theory. From information i gathered, I believe that the 4 girls have no relation with each other other than that they've been grouped together for some sort of school thing. They probably start off with very little strength, power, speed, but as they fight they grow stronger. A series is only good if characters develop over time, and this would be the easiest way to do that.
