From Life.2: "Ever since Rossweisse-san joined us as a comrade, she had been conducting research on defense and barrier-related magic, and she had become quite skilled in the area. Ah, demonic power and magic were two different things. Demonic power was a superpower that Devils possessed since their birth. The analysis of a Devil’s demonic power and the miracles created by God to recreate them through their own theory and formula was called magic. One could also say that it was a technique of creating a supernatural phenomenon. Starting from Rossweisse-san, there were also many of my comrades who were learning magic. "
