Yuki, a young pop star, suffers an intermittent inability to sing that drives the central conflict. This vocal block stems from latent psychic powers and profound psychological distress, directly linked to a religious cult led by her mother. Her mother intends to transfer both the cult's leadership and supernatural abilities to her, a plan clashing with her father's agenda; he hires a psycho diver as a distraction while secretly attempting to seize her powers for himself.

A repressed childhood trauma fuels her instability: she accidentally killed a friend during a board game using uncontrolled psychic abilities. This event manifests as intense guilt and conjures a destructive alter ego during psycho-diving sessions. Her subconscious reveals layers of conflicting loyalties, particularly an unresolved affection for her mother despite the cult's harmful influence.

Her music includes the opening theme "Warefare-Beware" and closing theme "THE END". One sequence features a stylized music video depicting her destroying a burning car with a guitar and undergoing incarceration, symbolizing rebellion and artistic expression. The English adaptation significantly alters these songs, adding rapped lyrics and shifting vocal styles.

Following successful intervention, her psychic instability resolves. She returns to singing, dedicating a new album to the psycho diver and deceased associates, signaling emotional reconciliation.
