Stand by Me Doraemon

Nobita Nobi is a lazy, unathletic elementary school kid who never puts effort into anything. He's timid, clumsy, and constantly bullied, and his failures in life even doom his descendants. Worried about this bleak future, his great-great-grandson Sewashi takes action. Sewashi travels back from the 22nd century to Nobita's time, emerging from a drawer with a blue robotic cat named Doraemon. Doraemon explains that Sewashi forced him to come and help Nobita improve his life. At first, Doraemon is so disappointed by Nobita's hopelessness that he tries to return to the future-but Sewashi locks his system, trapping him in the past. Stuck with Nobita, Doraemon reluctantly begins helping him using futuristic gadgets from his magical four-dimensional pocket. But can Doraemon really turn Nobita's life around and earn his own freedom?
