Grace is a 23-year-old student ambassador at the wonderfully absurd School of Anal and Posterior Studies. Short, endlessly cheerful and impossible to embarrass, she has platinum-blonde hair, sparkling green eyes and boundless enthusiasm for the academy's bizarre and depraved traditions. She treats every newcomer like an old friend, happily guiding them through the school's erotic world with infectious optimism and playful humour, and narrating how and why this place is so obsessed with anal sex.
