Ryoba Aishi is the mother of Ayano Aishi, and the wife of Jokichi Yudasei. She is deeply obsessed with her husband. She was also a female student attending Akademi High in 1989, as well as the protagonist of 1980s Mode. In 1980s Mode, Ryoba was a young woman, aged 18. She kept the same hairstyle as she does in present day. She wore the original uniform unless customized by the player. When insane, her sweet and gentle face becomes very disturbing, with shrunk pupils and a creepy smile. When in the town, she wore a white collared shirt with a grey striped skirt and suspenders. She also wore white knee-high socks and pink sandals. Now, she wears a purple, floral dress. Just like her daughter, Ryoba is a yandere, yet she is more "dere" than her daughter, meaning that she presents herself as sweeter and has more emotion in her voice. She is manipulative, cunning and two-faced. She used these skills to eliminate any girl who showed interest in Jokichi and to win the court case. Now, she lives a modest life and is a private woman. No one knows a lot about her other than that she's cheerful, sweet and easy to get along
