Kūsō Kagaku Sekai Gulliver Boy is one of the games based on the anime series Gulliver Boy, quite different from the PC Engine CD game of the same name. You are a boy named Gulliver, who lives together with his two best friends - the girl Misty and the young inventor Edison - in Venice, Italy. The evil Prince of Spain, Judou, is after the mysterious Blue Crystals who grant immense power to those who possess them. Gulliver's father was apparently connected to the secret of the Crystals, and was mercilessly killed by Judou. Now Gulliver swears revenge and embarks, together with Misty and Edison, on a grand journey that will take him to several cities and countries all over the world, from Rome to the Himalayas.
