Arma wants to be the best firefighter in the world! Unfortunately for her, so far this has only meant that she's hypervigilant about any teeny tiny bit of smoke that she detects, routinely triggering onboxious and adrenaline-pumping false alarms. All of this constant anxiety has also had the effect of wearing her down over time, such that her batteries are almost completely drained. She has PTSD due to her last home burning down, due to her staying silent one time when a spark burned the house.
