Dr. Ashimori, a human woman and Setoro’s supervisor, oversees his surveillance of the Time of Eve café. She holds classified knowledge of a critical event from a decade earlier, in which a young girl—later revealed as Nagi—was harmed. This incident is subtly linked to the Ethics Committee, though her specific involvement remains unclear.

Her duties extend to visiting the Sakisaka household and clashing with Shiotsuki, Nagi’s guardian. A post-credits scene depicts her arguing with him before a younger Nagi, though their relationship is not definitively established. Demonstrating a ruthless practicality, she attacks an android with a pipe, underscoring her willingness to employ force against artificial beings.

A copy of *Android Promotion Committee* rests on her desk, suggesting ties to a group potentially opposing the Ethics Committee. This aligns with her access to confidential records and her assignment of Setoro to probe the café, yet her ultimate goals stay enigmatic.

Her awareness of Nagi’s past and confrontations with figures like Shiotsuki mark her as an influential player in human-android societal conflicts. However, her personal history, deeper background, and precise role in unfolding events remain unexplored in official sources.
