A staff member at Logios, she serves as Jeremiah's secretary. With neatly trimmed black hair and a suit, she exudes a capable and professional aura. Her main role is to provide comprehensive support to the DOLL unit.

She is cheerful, compassionate, and kind, always prioritizing the well-being of the girls in the DOLL unit. Despite her friendly nature, she is also strong-willed and unafraid to voice her opinions to Onogi and Jeremiah. She places great importance on the mental health of the girls, often saying "we are not a military," and has relaxed various rules for their benefit.

She lost her brother, who had moved to the city for university, during the Great Collapse.
