Yi Xi, also known as the "meatgirl" from the song "Butcher's Vanity," is a deeply unsettling character. She has an eerie, unnerving smile and a dangerous demeanor. She is often seen brandishing a large cleaver, which she seems very comfortable with. Her personality is a disturbing mix of philosophical musings on the "beauty of life" and a sinister, threatening presence that suggests a psychopathic or cannibalistic nature. She is bilingual, speaking both Chinese and English.
