2001 film by Tatsuo Satō

In the final months of World War II, 14-year-old Seita and his sister Setsuko are orphaned when their mother is killed during an air raid in Kobe, Japan. After a falling out with their aunt, they move into an abandoned bomb shelter. With no surviving relatives and their emergency rations depleted, Seita and Setsuko struggle to survive.

Cyborg detective Batou is assigned to investigate a series of murders committed by gynoids—doll-like cyborgs, which all malfunctioned, killed, then self-destructed afterwards. The brains of the gynoids initialize in order to protect their manufacturer's software, but in one gynoid, which Batou himself neutralized, one file remains: a voice speaking the phrase "Help me."
