In a world where dragons are not just fantasy but live in fairly constant contact with humans, there exists an organization called Toryumon. The organization acts as a middle man between the human race and dragons so that both societies can live harmoniously. Teenager Rukopio is a part of Toyrumon but his dragonism, the ability to talk to dragons, makes him an important and very rare member as there are only a handful of people with that ability.
Rukopio is pure hearted and sometimes he's taken advantage of by people with ulterior motives. However, that doesn’t stop him from trying to convey to people that dragons are not blood thirsty creatures, but rather intelligent beings with family and friends, just like humans. Rukopio continues his work for the Toryumon so that humans and dragons can coexist.
