Umineko no Naku Koro ni Murasaki: Forgery of the Purple logic

A manga-exclusive series by Kurumi Suzuhiro, this story builds upon the purple declaration concept introduced by Bernkastel in *Twilight of the Golden Witch*. The narrative incorporates the red truth, which remains valid despite fewer games occurring than usual. Knox's rules are presented in red to indicate their applicability within the game's framework. The events occur separately from the main storyline.
