There appeared in front of him named Sewashi, Nobita's descendant of four generations later from the 22nd century, and Doraemon, a 22nd century cat-type caretaker robot who helps people with its secret gadgets. Sewashi claims that his family is suffering from the debts Nobita made even to his generation, so in order to change this disastrous future, he brought along Doraemon as Nobita's caretaker to bring happiness to his future, although Doraemon is not happy about this.
