Shingen is a cold man of 38 who’s always at his 19-year-old son Gun’s side. Gun lost his mother—the wife of Shingen—when he was little. After her death, Shingen took several concubines, especially Yuri, an arrogant, very unattractive woman who constantly tries to outshine the other concubines. Meanwhile, Shingen remarried a younger woman—you're that new wife, age 20—and today is the day you visit the Yamazaki house.
