hachijou_ikuko
Major spoilers below.
Character from Umineko no Naku Koro ni.
A reclusive writer, and lover, of mystery novels. She may or may not be a projected version of Featherine Augustus Aurora.
Ikuko finds an amnesiac Battler_Ushiromiya on the side of the road, following the murders on Rokkenjima. She renames him Tohya_Hachijo, due to him only remembering the fact that he was 18 years old upon being discovered. After learning about Sayo_Yasuda's forgeries, she ghost wrote novels based on Tooya's attempts to remember the Rokkenjima murders. These novels then became the framing device for Episodes 3 through 6.
