tells the story of the life of a lazy 5th grade boy named Nobi Nobita who was visited by a robot cat named Doraemon who came from the 22nd century.
He was sent to help Nobita keep Nobita's offspring enjoying his success rather than having to suffer from future financial debt - which will happen in the future - caused by Nobita's stupidity.
Doraemon is sent back to Nobita's lifetime by Nobita's great-grandson, Sewashi, to improve Nobita's life in order for his offspring to experience a better life.
Doraemon is the title of a popular manga composed by Fujiko F. Fujio since 1969.
