The Graceful and Stern Yoriko-san

The manga follows Shindou Yoriko, a 29-year-old Kyoto cigarette shop owner who has a sharp look in her eyes but is actually a kind-hearted person. It may not come across, but she truly loves the city of Kyoto, and is willing to give up some of her time to share that love with tourists and other visitors (as long as they don't get on her nerves).
