Shitamachi in Tokyo’s Ota Ward, not far from Haneda Airport, has a variety of atmospheres. There is an old manga-centered bookstore \”Kujukudo\”. The owner of the shop is Kujuku Sakura (52). There is a room called \”たまりば\” in the depths of the used bookstore, where people who have nowhere to go gather. As a result, the host Sakura will delve deeper and ask for free parent-child donuts. Those who are satisfied on an empty stomach will start to tell Sakura bit by bit about her.
