Stand By Me Doraemon

Nobita's laziness, bad luck, and lack of confidence are destined to leave painful consequences for generations. To change that future, his descendant Sewashi arrives from the 22nd century with Doraemon, a robotic cat ordered to help Nobita become happy.

Doraemon's futuristic gadgets can solve almost any immediate problem, but Nobita's greatest challenge cannot be fixed by a machine: he must learn to make choices that change his own life, while the friendship growing between him and Doraemon makes the thought of eventually parting increasingly difficult.
