Fujiko F. Fujio's beloved manga and anime Doraemon was the story of underachieving fifth grader Nobita, whose great-great grandson sends the titular, slightly defective robot cat back in time to help Nobita be less of a screw-up. In Toyota's latest ad campaign, we see Nobita, as well as bully Gian, 20 years later and check if Doraemon's trip back in time helped.
