Aria is a girl in her late teens who is seen as the “rookie” among the Coalition of Five, as she just started committing crimes recently. She commits acts of villainy out of boredom rather than conviction, and is a pretty easy going person. Aria's quirk, Air Filtration, allows her to absorb air through pores in her arms, and then unleash it as powerful wind-based attacks. Aria’s quirk also allows her to absorb specific air-particles only - such as oxygen for instance, in order to suffocate her foes, however, this is only effective indoors.
