Lux's childhood friend who is frail, has a notably large bust, and has a sleepy expression on her face. She wields the Divine Drag-Ride "Typhon." She comes from the powerful and influential Aingram merchant house and took Lux and Airi in after their mother's death. It is revealed that Philuffy was a victim of human experimentation using poisons and weapons by military authorities by the old Arcadia Empire who ignored her sister Relie's pleas for her release.

It was this incident that made Lux decide to join Fugil's coup d'etat and pilot the "Bahamut" though he has since forgotten the incident after several years.
