Osamu Uemachi  

, 上町 修

Yoshie's son is both an attorney at Shiro's law firm and skilled in bankruptcy and civil rehabilitation law. Although he initially focused on these areas, his interest shifted towards criminal cases when he was assigned a murder case later on. He is married to Haruna, who stays at home and takes care of the household, and they have two children together. Initially, Yoshie maintained a slender physique; however, after marrying and entrusting housekeeping duties to Haruna, his weight increased due to overindulgence in food and drink.
