Megumi Oohara

The story is based on Robert Louis Stevenson's Treasure Island novel.

One day Doraemon, Nobita, Shizuka, Gian and Suneo were shooting a film as space heroes. When they were shooting the film in the open lot a boy called Aron comes and alerts them of aliens attacking his planet. They agree to help him by turning into real superheroes, but it isn't as easy as it looks.

In the suburbs of Tokyo some time ago, there lived a clumsy boy about 10 years old. There appeared in front of him named Sewashi, Nobita's descendant of four generations later from the 22nd century, and Doraemon, a 22nd century cat-type caretaker robot who helps people with its secret gadgets. Sewashi claims that his family is suffering from the debts Nobita made even to his generation, so in order to change this disastrous future, he brought along Doraemon as Nobita's caretaker to bring happiness to his future, although Doraemon is not happy about this. And so Sewashi installed an accomplishment program into Doraemon forcing him to take care of Nobita. Unless he makes Nobita happy, Doraemon can no longer go back to the 22nd century. This is how the life of Doraemon and Nobita begins. Will Doraemon succeed this mission and return to the 22nd century?
