Coming out from an egg the size of a man from a volcano, comes Guzura, a dinosaur half rhinoceros half dragon. Adopted by the Nuketa family he's puzzled by the human world always causing confusion by his own clumsiness. He can spit fire, eat metal and has super force but despite that he's a coward and is scared by syringes, which is bad for him because there's a doctor alyways trying to sting him with one.
