Armor manages the bookstore's comics section, specifically overseeing the boys' love (BL) department. Her appearance is defined by a distinctive western-style war helmet that fully conceals her head, featuring a white plume. This headgear visibly evokes the heroic male figures prevalent in the media she admires. Professionally, she pours considerable passion into her role and shows deep investment in the materials she handles. She maintains strong enthusiasm for both BL content and male idols, actively sharing this interest by organizing trips for coworkers to attend idol performances. Her connection to the books extends beyond merchandising; she becomes visibly distressed when titles face bans, experiencing conflict between her responsibilities as a bookseller and her personal advocacy for reader access. Her management style merges professional dedication with fandom enthusiasm, positioning her as both an authority figure and engaged participant within the bookstore. The helmet serves the dual purpose of providing anonymity while reflecting her admiration for the heroic archetypes found in the genres she curates.
