Helena

Gesicht's wife, a robot. She worries about her husband, who is busy with his work as a detective. Her profession is an interior designer. Although she has no memory of it, there is a record that she attempted to travel to Japan with her husband but canceled at the last minute. After her husband Gesicht's death, she came to Japan to deliver his memory chip to Dr. Tenma. Later, she met Atom, who had Gesicht's chip inserted, and realized that her husband's soul was living within Atom.

As evidence of her artificial brain "evolving," she has not fully accepted Gesicht's death. When she visited Japan two months after his death, she hid her sadness with a brave demeanor in front of Ochanomizu and Hoffman, but broke down in tears when prompted by Tenma. Her grief was so profound that it moved Tenma, who had struggled to accept Atom's death, to tears. Although she vaguely sensed that she was forgetting something important, she could not recover the memory of her child Robita. Atom, who knew the truth, told Helena a "lie" to save her heart.
