Cona Madaya is a supporting character in Overman King Gainer, recognized as a member of the Gauli squad. At twenty-seven years old, she serves as the team’s maintenance chief, holding the crucial responsibility of overseeing the upkeep and repair of the Overman and Silhouette machines.

Her personality is notably spirited and precocious, often described as boisterous, which contrasts with her technical role. Despite her age, she often behaves in a manner that is less mature, coming across as somewhat childish for a woman in her late twenties. In her duties, she is highly competent, possessing genuine skill as a mechanic. She works diligently behind the scenes to adjust, repair, and maintain the Overman, providing essential technical support to the pilot Gainer Sanga from the shadows.

Cona’s personal motivations are subtly woven into her interactions. She appears to harbor romantic feelings for Gain Bijou, and her character has a noted weakness for adult men, suggesting a tendency to be easily charmed or affected by masculine figures older than herself. Her key relationships are primarily professional, centered on her role as chief of maintenance for the squad led by Hughes Gauli. Her most significant dynamic is with the pilot Gainer, whom she supports technically, though her personal interest seems more directed toward Gain.

Her character does not undergo a dramatic transformation but provides consistent logistical and technical support essential to the group’s survival and mobility. Her notable abilities lie in her mechanical expertise and her skill in keeping complex war machines operational under what are likely difficult circumstances.
