Famicom Jump II: Saikyou no 7-nin

In Jump World, peace had been restored after 16 heroes defeated the villains—led by Piccolo Daimaou—who had plotted a rebellion.

In the Great Temple, where the spirit of Jump World resides, the three flames—the source of “Friendship,” “Effort,” and “Victory” in *Weekly Shounen Jump*—burned brightly.
However, those flames were beginning to fade. It seemed that another crisis was about to befall the world.
To protect the Great Temple, the Spirit sealed the Great Gate and selected the seven bravest heroes in the current Jump World.
When the seven heroes gather at the Great Temple, the Great Gate will open, and a new battle will begin.

Famicom Jump II: Saikyou no 7-nin is a 1991 RPG for the Nintendo Family Computer published by Bandai. The sequel to Famicom Jump: Hero Retsuden, the game features seven main characters (as the subtitle indicates) from different Weekly Shōnen Jump manga serialized at the time. Only four of the 16 represented titles from the original are brought back, while the remaining three are new to the sequel. There would not be another crossover game until the release of Jump Super Stars and Jump Ultimate Stars. (of which six of these series would be represented, the only one not being Magical Tarurūto-kun.)
