Maebara, Aiko

前原藍子

Maebara Aiko is a character in the Higurashi no Naku Koro ni series and the mother of Maebara Keiichi. She makes her first appearance in Onikakushi-hen, alongside her husband, Maebara Ichirou. Although she is rarely seen in the anime, she appears on various occasions throughout the manga adaptations. In the anime, it is a recurring habit that her face is not fully shown.
In Tatarigoroshi-hen, Keiichi reveals that she is very fond of detective novels and reads all kinds of crime novels by different writers from all over the world (including books by Agatha Christie such as And Then There Were None and Murder on the Orient Express). She also wrote a crime novel once and contributed to a crime novel contest. She easily reveals the trick of the perfect crime to Keiichi (not letting the "introduction" begin), which helps him to murder Houjou Teppei. As Ooishi states, she graduated from a "humble women's university".
