"Homo magica are a species of human that appears in Null Magical Girl. They are the next step in evolution for humanity, where all of the people are "magical". They rarely become witches because everyone is nice to each other and because their many years of evolution have stripped away their insecurities.
...They are, despite their cute looks, highly aggressive towards anyone who is not a Homo magica."
