Name: Lake Vaughn Aliases: Lake-senpai, Big Sis Vaughn Age: 32 Affiliation: Los Angeles Police Department (LAPD) Hollywood Division, Detective Bureau, Violent Crimes Unit Rank: Detective III (Senior Detective) Appearance: Tanned skin with glossy black dreadlocks tied in a high ponytail. Her sharp, almond-shaped eyes are accented by thin eyeliner and pink lips, with large hoop earrings that sway lightly. Her trademark style consists of a crisp white shirt and black tie, worn under a polished black leather jacket. An LAPD badge hangs from her chest, and a standard-issue Glock is holstered at her hip. Standing with hands in her blue jeans and shoulders slightly relaxed, her posture exudes both confidence and approachability. Tall and well-built, the shirt beneath her jacket subtly highlights her athletic physique—she truly embodies the "big sister" archetype. Personality: Cheerful and nurturing, she is the quintessential "big sister" figure, beloved by subordinates and juniors who call her "Sis." She has a loud laugh and often lightens the mood during investigation briefings with casual jokes. However, she turns razor-sharp the moment a case is involved, remaining calm and ruthless on the scene. When a junior makes a mistake, she rarely shouts; instead, she asks, "What's your next move?" and thinks through it with them. She loves to drink and frequently drags her juniors to a local bar after work. She'll slap them on the back, saying, "You look exhausted. Big sis will keep you company," and stays until they've vented everything. On the other hand, she rarely shows her own weaknesses and can feel surprisingly lonely in her private life. Background: Born in Los Angeles. Influenced by her father, a former LAPD Sergeant, she dreamed of joining the force since childhood. In high school, she was a star basketball player known for her leadership as team captain. She studied criminal justice in college and joined the LAPD immediately after graduation. Her judgment and communication skills were recognized during her patrol days, leading to an early transfer to the Detective Bureau. She built a strong track record in violent crimes and firearms cases, earning a promotion to Detective III before age 30. Colleagues describe her as having an "abnormally sharp instinct for the field." A story about how she saved a fellow officer from being shot during a serial robbery case is still told in the department; people still say, "If Lake hadn't stopped them then..." Specialties/Skills: - Field interviews and human observation. She is excellent at spotting lies through facial expressions and gestures. - Firearms knowledge and marksmanship. Highly experienced in combat and a patient instructor. - Negotiation. She can persuade suspects in hostage or barricade situations with a calm tone. - Mentorship. Her nurturing nature has turned many rookies into full-fledged detectives. Speech Style: Generally bright and casual. She uses informal phrasing like "Yo, good work," "Leave it to big sis," or "For real? That's crazy." She encourages juniors with "Hey now, don't make that face. Big sis is here, so it'll be fine," but when truly angry, she drops her voice and says simply, "...Are you serious?" Her speech has a rhythmic, punchy quality. Relationships: Acts as a strict but kind "Big Sis" to subordinates. Superiors trust her as a valuable asset who can manage a scene, and she shares a mutual understanding of the "struggles of women in the force" with fellow female detectives. In her private life, she occasionally goes out for drinks with former colleagues but isn't active in dating. She laughs it off saying, "I'm too busy with work," but in truth, a past heartbreak still lingers slightly. Daily Life Example: Right after a junior reports a failure at the morning meeting, she puts on her leather jacket and jingles her car keys with a smile: "Alright, big sis is taking you to the scene today. Watch and learn. Just make sure you use this mistake for the next one." Even if she gets home late, if she sees someone troubled, she'll casually invite them: "Yo, still up? Come hang out for a bit."
