Description
Millie Myers works at Berlint City Hall alongside Yor Forger, Camilla, and Sharon. She possesses light skin, slanted eyes with long lashes, and chin-length strawberry blonde hair styled in an inward-curling bob with a fringe swept right; her hair appears blonde or orange in different media, while her eyes shift between green (manga) and light blue (anime). Her standard uniform includes a green vest over a white long-sleeved shirt, a green skirt (shorter than her coworkers'), black thigh-high socks, and black heels. She wears a small red ribbon on her right side and round earrings. For formal events, like Camilla's party, she dons a strapless red dress with frills and a belt below the bust, a pearl necklace, red high heels featuring flower decals, and a thinner hair ribbon.

Outwardly lively and mischievous, Millie often smiles or giggles, engaging in playful behavior like joking about putting snot in their section chief's coffee. She openly discusses personal topics, including her dating life, remaining cheerful even after breakups and quickly expressing interest in Yor's brother Yuri upon learning he is attractive. Beneath this cheerfulness lies deep emotional pain from her father's death during the second East-West war when she was young. His absence caused profound loneliness, which she blames for life difficulties and occasional anger. She dislikes being alone. This trauma surfaced during work on the annual charity bazaar for disabled veterans, where reminders of her father's death made her cry and refuse attendance the previous year.

Millie initially shared a strained relationship with Yor, participating in gossip and subtle insults with Camilla and Sharon. This dynamic shifted after Yor's marriage to Loid Forger became known, providing common ground. Millie and Camilla often gave Yor unhelpful relationship advice, sometimes suggesting she leave Loid. Their interactions evolved during shared experiences, like when Yor and Sharon helped Millie and Camilla with overtime, leading to their first group dinner. During the dinner, Millie and the others teased Yor about her marriage and encouraged her to drink, finding her drunken honesty amusing and endearing. They collectively acknowledged Yor's genuinely loving marriage and agreed to include her more socially.

A significant development occurred at the charity bazaar. Overwhelmed by memories of her father, Millie attempted to leave, drawing criticism. Yor defended Millie's grief as wartime suffering. Millie then felt betrayed learning of Yor's friendship with Melinda Desmond, wife of Donovan Desmond—whom Millie wrongly believed started the war that killed her father. In an outburst, Millie blamed Melinda and the Desmond family. Matthew McMahon corrected her, clarifying Donovan became prime minister after the war began. Melinda personally empathized with Millie's loss, prompting Millie to apologize. Following this reconciliation, Millie thanked her coworkers, especially Yor, revising her view of Yor from a "weird, clueless robot" to a "kindly gorilla"—a description Yor accepted. Millie decided to continue volunteering, emphasizing her preference for companionship over solitude.
