The protagonist, 27-year-old former nurse (played with devastating nuance by rising star Mei Kiryuu), is not a criminal. She is a victim of a medical lawsuit fraud. To pay off a debt she never truly owed, she surrenders her civil rights and is re-cataloged as Unit EBWH-163 .

Colloquially known as Alat Bantu (Aids/Tools), these are
In a stunning narrative turn, Aiko is rented by a young man who is himself a failed HAU—a "defective unit" who was returned for being "emotionally inefficient." He does not ask Aiko to perform any task. Instead, he teaches her to be bad at her job. To drop things. To walk slowly. To ask "Why?" Without revealing the ending
