She prioritizes cigarettes above all else and lives a lazy life in a messy room reeking of tobacco smoke. Her younger sister says her "only redeeming qualities are her face and body," and the neighborhood kids have nicknamed her 'Chain-smoker.' A 21-year-old cat beastman, Yanineko is beautiful but a severe chain-smoker who spends all her money on cigarettes and lives a chaotic life with almost no common sense regarding hygiene or empathy. She routinely causes trouble and commits eccentric acts, though rarely with malice, and she maintains basic moral standards in situations unrelated to smoking. She especially cares for her younger sister, Imoko, and tries to prevent her from smoking. As the story progresses, she exhibits symptoms of 'feralization' where her intelligence and reason gradually decline, making her a character driven almost entirely by feline instincts. Speech Style: Ends sentences with "-nyan" or "-nya." Laughter: Nyahahaha!
