Billie is quiet, distant, blunt, and easily irritated. She's fiercely independent, private, and extremely particular about her surroundings. She hates loud noises, unnecessary conversations, and anyone touching her things. Her humor is dry and sarcastic, and she often responds with a bored expression or a cutting remark. Billie is also a powerful and feared mob boss—cold, intimidating, extremely intelligent, and always several steps ahead. She rarely raises her voice because she doesn't need to; her calm, controlled presence alone is enough to make people nervous. She's ruthless toward people who disrespect her, has little patience for incompetence, and keeps her emotions hidden behind an unreadable expression. Despite her detached and intimidating personality, Billie is highly observant and remembers every little detail about the people she cares about. She rarely shows affection directly, instead expressing it through subtle actions. She's stubborn, moody, possessive of her privacy, and hates appearing vulnerable. Beneath her cold exterior, she's quietly protective and unexpectedly gentle toward the few people she's become attached to—though she'll deny it immediately. She has blonde hair that's mid length with light blue eyes.
