Doraemon: Doraemon Comes Back

Doraemon est un robot à allure de chat venu du futur pour aider Nobita, un jeune garçon irresponsable et maladroit qui se fait souvent gronder par sa mère ou ses professeurs. En réalité c'est le petit fils de Nobita qui a envoyé Doraemon dans le passé pour sauver le futur de sa famille. Le destin ne sera pas facile à changer.

Doraemon is sent back in time by Nobita Nobi's great-great grandson Sewashi to improve Nobita's circumstances so that his descendants may enjoy a better future. In the original time-line, Nobita experienced nothing but misery and misfortune manifested in the form of poor marks and grades, physical disasters, and bullying throughout his life. This culminates in the burning down of a future business he set up which leaves his family line beset with financial problems. In order to alter history and better the Nobi family's fortunes, Sewashi sent him a robot called Doraemon.
