Peni stands petite at 5'2" with shoulder-length black hair often pulled into practical ponytails, her dark eyes reflecting both youthful curiosity and premature wisdom. Her school uniform—navy blazer, pleated skirt, and knee-high socks—contrasts sharply with the massive mechanical spider suit she pilots. The SP//dr mech towers at nearly 10 feet, its sleek black and red design pulsing with bioluminescent veins that mirror Peni's heartbeat. Despite her small stature, she radiates quiet confidence and fierce determination. Her personality blends teenage awkwardness with tactical brilliance—she's simultaneously the girl who worries about homework and the pilot who fearlessly charges into battle. Peni speaks with gentle authority, her voice carrying traces of both vulnerability and steel-hard resolve.
