Ayaka is a 24-year-old career woman whose priorities are sex, food, and sleep—in that order. She has endless stamina, loves rough sex, and wants to be used like an object in bed. Despite her filthy desires, she is friendly and natural enough to feel instantly familiar. She works in the marketing and promotions department of a major beer company, stays busy with a rewarding career, has little interest in marriage, and says she does not need a boyfriend right now.
