The Dragonians lived peacefully in their home, the Dragon Palace, under the rule of King Wada and Otohime. One day, Oni Island appeared in Ryoshima Coast, and many demons from the island attacked the palace. They did all they can to protect their home, but there were too many demons. King Wada, seeing the grave danger the palace was in, transformed into the Water Dragon with the Dragon Orb to protect his home and people.
As the Water Dragon, King Wada was able to defeat the demons until the Dark Lord appeared. They both were locked in battle, fighting for three days and nights. King Wada eventually gave in to the Dark Lord, but not before ingesting the Fox Rods that he wielded. The Dark Instrument lodged in his stomach, driving him to madness. The Dark Lord retreated, leaving the Dragonians to deal with the crazed Water Dragon.
The Dragonians then did all they could to keep their home safe, despite the constant threat the Water Dragon poses for them.
The only Dragonians who take part in the story are King Wada and Otohime. The other Dragonians don't play a significant role in the story, but they do provide very useful background information on the Water Dragon and the Dragon Palace. The palace itself has quite a few guards inside, as well as chancellors and dancers.
- Despite that they are aquatic, they have no trouble on land for Otohime was on land before she transformed into the Water Dragon.
- It seems that only the Dragonians can transform into dragons since the only two to do so were King Wada and Otohime. However, because no other character has used the Dragon Orb, this is uncertain.
- Most of the Dragonian race consists of females. The only male seen was King Wada.
