Keishi Masaki, a psychiatrist and former project leader at Kyushu Imperial University, pioneers experimental treatments for mental illness through a controversial hypothesis: mental disorders stem not from the brain but inherited genetic memories embedded in cellular structures. He likens the brain to a “movie screen” projecting ancestral psychological imprints, arguing present behaviors emerge from dormant legacies passed through bloodlines—a notion exemplified by patient Ichiro Kure, who allegedly harbored homicidal urges inherited from a Chinese ancestor who murdered his fiancée.

Masaki’s methods deploy documents, films, and artifacts to awaken latent memories, seeking proof for his theory. His collaboration with forensic medic Professor Wakabayashi is strained by professional rivalry and clashing methodologies. Initial reports state Masaki died by suicide weeks before the central narrative, yet later encounters with a man claiming his identity fuel speculation of staged death, hallucination, or manipulation.

Central to his practice are meta-cinematic experiments, including a film-within-a-film screening where a protagonist’s shifting identity mirrors memory’s unreliability. His treatise *Lament of the Reviewer* condemns forcing logic onto chaos, framing madness as an inherited inevitability. These theories dissolve boundaries between reality, delusion, and ancestral influence, leaving patients and colleagues questioning whether his interventions heal or deepen psychological fractures.

Alternate iterations, like a 2012 CG anime OVA, transplant Masaki’s core concepts into futuristic settings, emphasizing his theories’ timeless resonance. His legacy endures through fragmented writings and contentious academic reinterpretations, cementing his duality as a psychiatric visionary and anarchic provocateur.
