Hakuaki Kyouryuu Kitan: Ryuu no Kuni no Yuta

Yuta, who lives in Naga on the outskirts of Nanosland, rides an elderly Pachycephalosaurus named Jisama to the meeting place to apply for a job as a guide for a Navy caravan. Although it seemed impossible given Jisama’s slow pace, Yuta was successfully hired and begins working alongside his childhood friend Phil and the others. However, on the way, they encounter a Tyrannosaurus that shouldn’t have been there, and the slow-moving Jisama becomes the Tyrannosaurus’s target. Yuta, who had been hired specifically for this very situation, finds himself in a life-or-death crisis, but for some reason, he begins to hear Jisama’s voice. By following its advice, he succeeds in fending off the Tyrannosaurus. An adventure drama manga set in a world where dinosaurs and humans live together, following the growth of a young dinosaur handler. (Source: Akita Shoten, translated)
