Xiaoling (voiced by Rena Nounen) is a girl who is slow and confused all day long. Her biggest hobby is painting. Seeing that she has reached the age of marriage, Xiaoling came to Kure City under the arrangement of her parents and married a man named Hojo Shusaku (voiced by Yoshimasa Hosoya), becoming the daughter-in-law of the Hojo family. Keiko (voiced by Miko Omi) is Shusaku's sister. She lives back in her mother's house with her daughter Harumi (voiced by Nazuki Inaba). Unlike the virtuous and honest Xiaoling, Keiko has a flamboyant and shrewd personality. Although she is often dissatisfied with the submissive Xiaoling, the relationship between the two is actually very good. The war began, more and more fighter planes flew across the sky, and the piercing air defense alarms often broke the tranquility of the night. The shadow of war covered the lives of the Hojo family bit by bit. In an air raid, Harumi was unfortunately killed, and Xiaoling also lost her right hand and could no longer paint. However, in such a cruel situation, the family still did not give up the desire to survive.
