my favourite book is doraemon. In the story set in the 22nd century, Doraemon is a robot cat of the future run by the Matsushiba factory - a factory specializing in the production of robots.Doraemon has a small magic bag in front of his stomach that contains a lot of useful treasures of the future, which is why he is often borrowed by Nobita.
