Harumi Kuromura

Suzu's niece and Keiko's daughter. Harumi is a little girl aged around 6. She gets along with Suzu. She is fond of seeing warships in the sea, as her brother, Hisao, who lives in Shimonoseki, told her about the ships when living together. While walking with Suzu, she is killed in a time-delayed explosion of a US bomb near Hiro Naval Arsenal.
