Yes! But in this world magic exists so it is both!!
True, but the way Duwie is portrayed in the last chapter felt to unrealistic. Since Duwei is from the 21 century he should hold some idea of what the cosmos could hold, such as meteors and comets. But he just seemed so amazed that a meteorite hit earth, which shouldn't be surprising, however the size meteorite is amazing. I'm not taking credit away from the ancestor because she was able to sense the heavens with the use magic in a time that is lacking scientific improvement and religion was "science" and law. The part that I felt should have blown his mind is the idea that the cosmos hold a vast amount of magic.
Am I the only one screaming IT'S SCIENCE BITCH? No, okay.
