Neon Genesis Evangelion Role

Doi voices Naoko Akagi in Neon Genesis Evangelion, the systems scientist who designed NERV's MAGI supercomputer and is the mother of chief technology officer Ritsuko Akagi. The character appears only in flashback, and her story becomes one of the series' darkest threads, tied closely to the secrets Ritsuko later uncovers about NERV's founding and her mother's work. It is a brief but pivotal supporting role within the show's tightly wound mythology.
