"Consuming" air is possible. When you belch, or feel bloated, it is from "swallowing" air, which is a form of consumption. Babies often swallow air during feeding, it's why they need to be burped alot.

"Urano Metria" is not classified as a "Light Magic", but given how it looks, I'm merely drawing on assumption.
