Anna Winehouse is CEO of Ecohes, a pharmaceutical company engaged in medical research. She serves as a source of information on the bio-masks' origins and dangers, specifically their link to the Herst family. Anna reveals to Tina Herst that the masks originated as a medical treatment for a genetic illness, developed under Tina's grandfather, Gary Evans.

Anna provides critical details about an accident during the mask project's experimental phase. This accident caused the death of Julia Herst, who was pregnant with Tina. Julia's exposure to unstable energy was fatal and also affected the unborn Tina, requiring Tina to use a specialized mask for survival due to residual energy exposure.

Within the narrative, Anna acts protectively toward Tina Herst. She directly intervenes to shield Tina from Geffrey Connor, who seeks Tina's unique mask for his research. Her knowledge of the project's history and corporate connections positions her as an ally to James Blood and others investigating the mask conspiracy. She imparts key background about Julia Herst to Tina, bridging Tina's past with her present.

Anna engages in corporate-level conflicts, opposing the activities of LIVE Corporation and associated figures like Steven Martland and Geffrey Connor. This opposition stems from Ecohes's historical ties to the mask technology and her awareness of its misuse.

Later, Anna supports Tina's decision to explore using her mask-derived abilities for healing, facilitating Tina's understanding of her condition and legacy. No details are provided about her appearance, personality beyond this narrative function, or relationships outside those concerning the mask project and the Herst family.
