Amane is Maria Fiana Albert's bodyguard and close companion. She has dark black hair usually tied in a ponytail and frequently wears a gray dress with white gloves, projecting an air of strength.

Initially aloof and distant with everyone except Maria, Amane softened considerably after Noir Stardia and Luna Heela intervened to save Maria's life, becoming far more approachable and friendly. Her defining loyalty to Maria is absolute, shown by intense distress over Maria's life-threatening curse and unwavering dedication to her safety.

Her background as Maria's dedicated protector led her to accompany Maria to the Hero Academy entry examination, where she also achieved S-Class student status, reflecting her formidable abilities. Following the breaking of Maria's curse, Amane expressed profound gratitude toward Noir, forging a friendship with him. This evolving dynamic included moments where she displayed admiration for Noir, such as blushing while watching him during a school trip's communal bath.

Amane never discriminated against Noir due to his low-ranking noble status. When Maria fainted during a training match, Amane calmly intervened, reassuring Noir and taking charge of Maria's care rather than blaming him, demonstrating understanding and trust. Her bond with Maria transcends duty, characterized as a deep, genuine friendship where Amane's concern for Maria's wellbeing is profoundly personal.
