Doraemon - S04

Nobita Nobi is an elementary school student who hates studying, is bad at sports, and does everything half-heartedly. He is a pushover, unlucky, and afraid of many things. His personality makes him a failure in life, even affecting his descendants. This causes his great-great-grandson, Sewashi, to take matters into his own hands. 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 Sewashi pressured him into helping Nobita, with their ultimate goal being to make Nobita happy. 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?
