This paper argues that Perfect Blue uses its protagonist’s descent into psychosis to critique the construction of identity under the pressures of public consumption. Through a disorienting fusion of reality and delusion, the film demonstrates how the “gaze” of fans, the media, and the entertainment industry systematically erases the authentic self, replacing it with a performative commodity.

Kon visualizes this split through mise-en-scène. The real Mima wears casual, darker clothing, while the idol ghost wears the bright costume of CHAM!. The film’s editing famously refuses to provide stability. In one sequence, Mima wakes up in her apartment, looks in a mirror, and sees the idol; she then wakes up again on a Double Bind set, implying her entire life is a TV show; then she wakes up in a mental hospital. This hall-of-mirrors technique—what Kon called “the expansion of the network of delusion”—demonstrates that identity is no longer anchored to a body or memory, but to external media representations. Mima’s madness is not irrational; it is a logical response to an environment where authenticity is impossible.

Unlike conventional horror that externalizes evil (a monster, a ghost), Perfect Blue locates horror in the act of performance itself. Mima’s tragedy is that she cannot stop performing. Even in her most private moments, she practices smiles. The film suggests that for a public figure, the performance eventually consumes the performer.
