Sewashiko Goya serves as one of the scientists developing and maintaining the robot Daimidaler, collaborating closely with Moriko Tomoyose and Soriko Majikina. She exhibits the smallest physical stature among the trio, characterized by a notably childlike build. Her most distinctive trait remains an object resembling a piece of cloth perpetually hanging from her nose. Available sources do not explore her background story, character development across official media such as OVAs or spin-offs, specific personal history, origins, motivations, or evolution.
