Later that night, a janitor removes his body and digs through his possessions, finding nothing but a candy tin containing ashes and a few fragments of bone which he throws away into a nearby field. From the tin springs the spirit of the young boy followed by his little sister along with a cloud of fireflies. The spirit of the young boy, Seita (Tsutomu Tatsumi, English: J. Robert Spencer), narrates the story of how he and his sister, Setsuko (Ayano Shiraishi, English: Rhoda Chrosite), fared in the wake of the firebombings of Kobe during the war.14 year-old Seita and 4 year-old Setsuko live with their mother (Yoshiko Shinohara), English: Veronica Taylor) comfortably in Kobe while their father serves as a captain in the Imperial Japanese Navy.
