When the spirit arrives, shaking the ground with its voice, Midori thinks it's an earthquake, one mild enough to ignore, so she does. Later, when the voice resolves into sensible language, she hears the spirit out: ishito/i and itenshi/i and in need of her help. Midori thanks the spirit for its interest in her and asks it to leave: if there are angels, there must also be their opponents, and on the whole Midori would prefer to be Asuka.
