Description
Nias Carlin is a technical lieutenant assigned to the Seventh Imperial Weapons Factory within the interstellar empire. She is a young woman with short black hair, yellow eyes, and wears glasses, often seen in her uniform. She possesses a curvy, well-endowed figure and is recognized as physically attractive by those around her. Her reputation carries the nickname "regrettable beauty" due to a combination of her striking appearance and her awkward, socially inept personality.

As a weapons engineer, Nias is exceptionally gifted. She designs and develops advanced military hardware, but her creations tend to suffer from impractical designs that make them difficult to sell or deploy in the field. This leads to consistent lackluster sales for her work and a professional struggle to gain recognition. Her true talent becomes apparent when she is dispatched to the Banfield family to customize and upgrade Liam's mobile knight, Avid. The modifications make the unit highly effective, showcasing her skill when given the right direction and resources.

Her role in the story is primarily as a supporting character who provides technical support and weapon development. She develops a professional relationship with Liam, the protagonist, and her engineering prowess contributes to his military capabilities. Over time, she begins to move beyond her initial reputation as a poor saleswoman, with side material hinting at a hidden side of mad genius-level inventiveness. Her primary motivation is to succeed in her engineering work, though she often struggles with the disconnect between her technical brilliance and the practical demands of the market. She also interacts with other characters such as Yasushi, who finds her attractive. Nias Carlin's character arc involves growing from a frustrated, overlooked technician into a more confident and recognized innovator, particularly after her successful work on Liam's equipment. Her notable abilities lie in mechanical design, weapons engineering, and the customization of mobile knights and other imperial military technology.
