Yuki Kano, a prominent pop star, suffers sudden psychological disturbances that silence her singing voice, stemming from deep-seated trauma and unresolved mental conflicts. As her psychological state deteriorates, latent psycho-kinetic powers erupt uncontrollably, manifesting violently through physical harm and environmental destruction. Her condition connects directly to a sinister religious cult led by her mother, who intends to transfer her psychic abilities to Yuki, positioning her as the cult's successor. Opposing this, Yuki's father—her stage manager—orchestrates a betrayal, collaborating with external parties to eliminate the mother and seize Yuki's emerging powers for himself. This familial conflict traps Yuki in a violent power struggle.

A buried childhood trauma underpins her turmoil: an uncontrolled outburst of her powers during frustration accidentally killed a friend during a board game. During psycho-diving sessions into her subconscious, layered manifestations of guilt emerge. The surface layer reveals guilt over her lingering attachment to her mother despite the cult's malice. Deeper within, the repressed memory of the childhood incident surfaces. This inner turmoil materializes as a separate entity, "Dark Yuki," attacking intruders in her mental space.

After the external conflicts resolve with the elimination of her parents and the cult, Yuki undergoes a transformative psychological journey. Confronting and overcoming the "Dark Yuki" entity achieves mental stability. This healing restores her ability to sing. She dedicates her subsequent musical work to those involved in her recovery.
