Chiyoko Kure appears exclusively in the 2012 CG anime OVA adaptation of *Dogura Magura*, which expands her role beyond the original novel. She is the mother of Kure Ichirou. Her death during Ichirou's childbirth ignites the central conflict, becoming a source of his profound psychological trauma and ensuing mental instability.

Her legacy manifests through a painted scroll depicting the decomposition of her corpse. This scroll critically influences Ichirou's actions, particularly his violent assault on his fiancée, Kure Moyoko. Characters like Dr. Masaki theorize the scroll's imagery triggered inherited psychological disturbances within Ichirou, connecting his violence to ancestral patterns of madness.

Chiyoko's background emerges primarily through the perspectives of others. Conflicting accounts from Dr. Wakabayashi and Dr. Masaki regarding her death and its repercussions contribute to the narrative's unreliable nature. Their theories frame her as a victim whose tragedy perpetuates generational cycles of psychological turmoil.

The OVA adaptation introduces a key deviation: Chiyoko is depicted actively participating in psychological manipulations targeting Ichirou during his confinement, orchestrated by the doctors. This transforms her role beyond a passive historical figure.

Her character also connects to the original novel's "fetus dreaming" concept. One interpretation suggests the entire narrative unfolds within the subconscious of an unborn child, implicitly positioning Chiyoko as the mother carrying this child. This weaves her into the story as both a literal presence and a symbolic force within the protagonist's fractured reality.
