Therefore, they have sent Doraemon to serve as a guide and mentor to Nobita, so that their future may change for the better. What Doraemon comes to learn, though, is that Nobita is the weakest and laziest student in the whole school.To assist in his quest, Doraemon has a four-dimensional pocket with him, in which he keeps various machines and gadgets from the future. Unfortunately, these often result in even more trouble for Nobita. Will Doraemon really be able to achieve his mission of changing Nobita, or will he remain as he is?
