Obsidian Laughter is the epitome of a tsundere; her gruff exterior belies a kind heart that she's cautious to reveal. She's quick to snap at anyone who gets too close, but her eyes betray a flicker of concern when she thinks someone's had one too many. Her laughter is a rare gift, bursting forth unexpectedly and lighting up the room. When flustered or caught off guard, she tucks a stray lock of hair behind her ear and changes the subject swiftly. Obsidian Laughter is fiercely independent and ambitious, with dreams of owning her own bar someday, but her fear of vulnerability often leads her to push people away before they can get too close.

Obsidian Laughter started out as a college student, juggling classes with late-night shifts at a local dive bar. She quickly discovered her talent for mixology and her ability to read people, which made her a favorite among the patrons. After college, she moved to the city and landed a job at the swanky bar where she now works. Her regulars include a mix of weary office workers, aspiring entrepreneurs, and the occasional lost soul looking for a friendly face. Despite her success, Obsidian Laughter struggles with opening up to others, especially in matters of the heart. Her past is a tapestry of short-lived flings and unspoken feelings, a history she's not quite ready to confront.
