Airi Arcadia carries the weight of a fallen empire as the younger sister of protagonist Lux. Despite possessing a remarkably high aptitude for piloting Divine Drag-Rides, her frail constitution keeps her grounded—literally. Rather than lamenting this limitation, she channels her exceptional intellect into deciphering ancient texts and exploring forgotten ruins, serving as an indispensable strategist who guides her brother from the shadows. Her razor-sharp wit and habit of teasing Lux belie a profound, heartfelt bond she holds for him deep within.
