Anju Ryou is the former Deputy Secretary of the Department of Royal Commandment Affairs. Anju is a very charming man in his late 30s who possesses a strong resemblance to Sakujun Sa; Shuurei notes being around Anju reminds her of Sakujun. Anju frequently teases others, particularly Kouki Ki, and flirts with women, especially Kochou whom he raised. When Shuurei asks if he comes from a noble background, Anju casually mentions that he was adopted into a noble family. (Source: Saiunkoku Monogatari Wiki)
