Angelica began her career as Angers, the 15-year-old youngest member of the legendary idol group Ray. Possessing exceptional talent in singing, dancing, and magic—especially healing—her pure, innocent personality and small, cute appearance earned her the fan nickname "Little Archangel." She frequently incorporated the word "angel" into her speech. Exhibiting Chronic Hero Syndrome, she eagerly assisted anyone in need, healing injuries for large groups, which fueled her popularity.

Following Ray's disbandment three years later, triggered by leader Eliza's retirement and a career-ending injury, Angers joined the unit Sadistic★Candy. She adopted the new identity "Angelica," now aged 18. This change coincided with the aftermath of the "Devastating Witch Incident" involving Lucifer, which profoundly impacted her. Her once cheerful and altruistic personality became more jaded; she reacts strongly to being called an "old woman," hinting at unresolved trauma.

Within Ray, Angers served as "The Heart," balancing the group with her innocence while occasionally teasing other members. Her relationships with former Ray members, particularly Chloe (now the academy director), remain intact. Chloe acknowledges Angelica's enduring skill as a witch despite her altered demeanor. Angelica's magical expertise still centers on healing, though her willingness to use this ability appears diminished.

Physically, she has long, wavy light pink hair styled with small pigtails and blue eyes, maintaining her short stature. As Angers, she wore a distinct pink-and-white dress with thigh-high white socks and red accents. No significant alterations to her appearance as Angelica are detailed.
