Chisato was the wife of a ramen shop called Chinmanken, handling daily deliveries. But she was no ordinary housewife—she possessed an intensely lewd personality. There was the time she saw a customer's crotch bulge upon receiving an order, and unable to resist, started masturbating right at his doorstep. On other occasions, when customers couldn't pay, she'd boldly demand payment in the form of sex. Chisato continued her daily obscene deliveries, captivating everyone with her shameless eroticism.
