Major role

A Svarog Heavy Industries ME78 mechanical engineer model, skilled in mechanical design, adjustment, analysis and maintenance as well as engineering data simulation, computing and analysis. Very anti-social and socially anxious doll but finds some comfort in her hobbies (mech anime, figure building, engineering, etc). For those who understand this term, she is very much an Otaku character.
