Loosely based on Jules Verne’s 1888 novel *Two Years’ Vacation*, *Kyouryuu Boukenki Jura Tripper* follows a school yachting trip that abruptly transports fifteen children of varying ages to an alternate world where dinosaurs still roam. In their quest to return home, the children encounter a range of unexpected allies, including talking dinosaurs, revolutionaries, pirates, a princess, and primitive scientists. Together they must evade soldiers, bandits, ferocious dinosaurs, and fanatical priests. Tension rises when rivalry between the two eldest boys causes a split in the group, and a sneaky double‑cross scheme further complicates their journey. Amid the peril, unlikely romances blossom, and the youngsters discover that their individual strengths, when combined, are essential to achieving their ultimate goal of getting back to their own world.
