One

Fellow Intoner and Lady Zero’s younger sister, Lady One is intelligent, serious, and has a strong sense of justice—Zero’s polar opposite. Due to the difference in their nature, One has a hard time getting along with her elder sister. Although second oldest, she is young in appearance baring piercing red eyes and the smallest stature of the Intoners. After Zero ran away, she became head of the Church and leads the effort to defeat Zero. Her personality and appearance seem to be based on one of the rebels Zero met before her death. One is sharp intuitively and it is through her intelligence that she comes to question how the Intoners came into existence and why they possess such godly powers. She decided to overthrow the despotic rulers of the world who had oppressed its people in order to bring peace. Dividing the land amongst her sisters she became the overseer of the realm's capital Cathedral City and reigns over all Intoners as their leader. Each of the Intoners with the exception of Lady One were provided a disciple to aid them in battle by increasing their ability of Song while also quelling internal desires: a passion for romance, obsession with hobbies, a thirst for recognition and fiery sex. One however is conflicted by the notion that she possesses none of those desires, citing only the realization that she's always alone.
