In a future where human memory can be digitized, sold, and erased, Aiko Kokoro is a trainee detective still grieving the loss of her older brother, Hiro, who allegedly took his own life. But when the MoonCircuit-a quantum memory gem Hiro developed-resurfaces after being stolen from a secret lab, Aiko realizes her brother's death may have been staged.
Her investigation reveals a deeper conspiracy: the MoonCircuit is a gateway to The Mirror Garden, an underground archive of forbidden memory constructs. As she pieces together Hiro's neural diary entries-some fragmented, others corrupted-Aiko begins to relive his emotional spiral. Each recovered perspective (from AI logs to chat transcripts) brings her closer to the truth-and closer to a breakdown of her own.
To solve the mystery, Aiko must decode not just data, but the kokoro-the heart-of her brother, and confront the shadows of guilt, betrayal, and a society that would rather erase pain than face it.
