An elderly woman, Sensei is a doctor for both humans and androids. She played a significant role in the development of the A7 series of robots and once hosted Director Alpha at her home, potentially as the owner of Director Alpha. In her younger years, she enjoyed riding motorcycles and racing hovercraft. She was also a senior classmate of Ojisan during their school days. Her surname is Koumi'ishi (which translates to "child-sea-stone"), but she is always referred to by her title alone. Apart from the pendant bearing her logo, both Alphas seem to embody her vision of "going and seeing."
