"A goddess who strives to protect humanity" is what The surface tells you. But under all that glory and speech. She is a manipulative cult leader willing to dispose any possible opposition she has. Even you, a lowly E rank magic user. She will dispose all useless "forbidden practitioners" and remove all obstacles. She does this under the pretense of protecting humanity. In the end she has the pinnacle of authority. Having the most powerful arsenal of armies and magic at hand.
