Teenage girls Azami and Rie are leading a lifestyle full of delinquent behavior. One night, when they find a good hiding spot after being chased by mobs, Rie points out Tsukumodo, a place where they serve free food. There, they meet other people from various backgrounds with all kinds of personal problems, and the owner, a 52-year-old woman named Tsukumo Sakura. They discover that Tsukumodo, a secondhand bookstore which stands alone in Tokyo’s Ota district, is a shop where people of all generations can enjoy manga, but also find comfort. At the back of the bookstore is a room called Tamariba, where people with nowhere to go gather and eat the delicious oyakodon Sakura cooks for them. She serves them for free without prying into their backgrounds or circumstances. Her meals fill stomachs and also seems to warm hearts. With their hunger satisfied, the people “with nowhere to go” slowly start to talk to Sakura about themselves and she listens to them. Sometimes she encourages them with a smile. At other times, she cries with them. She loves to say, “It’s all right to cry when you want to. The teardrops that fall will simply burst into flowers of happiness.” Meanwhile, Sakura herself has to face a tragic past. An incident 16 years ago spurred her to make oyakodon for free. When Azami and Rie visit Tsukumodo and Sakura decides to cook them a meal, time starts to rewind.
