Stand By Me Doraemon

Nobita Nobi is an elementary student who hates studying, is bad at sports, and does everything half-heartedly. He is a pushover, unlucky, and fearful of many things. His personality makes him a failure in life, even affecting his progeny. This causes his great-great-grandchild, Sewashi, to take control of the situation. Sewashi travels back in time from the 22nd century to the 20th century to meet Nobita, who is shocked to see him appear out of his drawer alongside a blue robotic cat. The robotic cat calls himself Doraemon, who claims to have been pressured by Sewashi to assist Nobita, with their ultimate goal being to provide Nobita happiness. Frustrated after seeing Nobita's hopeless state, Doraemon decides to go back to the future. However, Sewashi activates a program within Doraemon that prevents him from doing so. Forced to stay, Doraemon helps Nobita using futuristic gadgets through his four-dimensional pocket—a bag containing anything inside it. Can Doraemon bring Nobita happiness and return to the future? Doraemon is a robotic cat that lives in the 22nd century, and is known as a caretaker who helps others with his futuristic gadgets. One day he is approached by Sewashi Nobi, the great-great-grandson of Nobi Nobita. Sewashi demands of Doraemon to go back to the past and make Nobita happy in order to prevent a disastrous and bleak future. Doraemon is not excited about this idea, but Sewashi installs a program into Doraemon and eventually sends him back to the past.
