King Wada (Ryuu-ou Wadatsumi, Dragon-King Wadatsumi) is the twenty seventh ruler of the Dragonians and husband to Otohime. When Oni Island appeared and the oceans became plagued by evil beings King Wada used the ancient Dragonian right of transformation to become the Dragonian’s guardian deity the water dragon to protect the Dragon Palace. He managed to steal the instrument wielded by the Dark Lord, however it lodged in his stomach and left him severely wounded. This caused Wada to fly into an uncontrollable rage during which he killed many innocents and sunk a cargo ship headed for Sei-an City.
Otohime needed the Dragon Orb within King Wada’s body to break the barrier surrounding Oni Island so she sent Ōkami Amaterasu. When the Dragon Orb was removed it killed King Wada who thanked Amaterasu for freeing him from madness. He later tried to warn Amaterasu about the priestess Rao who was Ninetails in disguise but Amaterasu misinterpreted the vision as Rao being attacked by Ninetails.
