Why Can a Fetish Be a Profession?

Pi Xing transmigrates to a world where innate preferences can be turned into professions. If your preference is elves, you can become an elf professional; if it's catgirls, you can become a catgirl professional. But Pi Xing is the only one who can draw professions for specific characters from works of fiction created after his arrival! "Whoa, there are beastfolk too?" "That's a furry thing." "...Then what are all those animals you see around town?" "Oh, they're probably migrant workers from South Fan next door." "???" "How ignorant. I've even seen an attack helicopter, a shopping bag, and a giant mushroom." Pi Xing looked at the white-haired, red-eyed beauties all over the streets, then at the little girl speaking to him with a perfectly serious expression, and fell into deep thought. Then Pi Xing called the police.
