The Hisakawa clan came into being sometime in medieval Japan, back when everyone still believed in Gods; initially a cult which branched away from the original teachings of both Buddhism and Shinto. Their worship revolved around an ambiant entity, a dragon who was a self-claimed god. This so-called God was one who would always grant favours for humans...in exchange for something in return. The dragon was a fulfiller of wishes, one could say. Morals were nonexistent in it's eyes- someone wanted another dead? An entire village? Or one wanted to be together with their love one despite obstacles that blocked their affection? No problem, with a simple oath of pronise, all of those desires and more can be reality.

It was because of the dragon's powers, that the cult formed. Entranced by the enigmatic being, the entire group became blood brothers and sisters in arms, and formed a pact with the dragon to have a taste of that magic. In exchange, they had to uphold the promise of handing over any child from the newest generation of both the head and branch families; for that child would be chosen to be the dragon's vessel. In order to grant the dragon's own wish-- to learn how it's truly like to be human. For the dragon found humans to be rather peculiar, and he himself was a little greedy.

However, people change, and time moves on. Cults such as the Hisakawa steadily declined as religious beliefs changed and the minority grew to be snuffed out. To their misfortune, their proclaimed God was unable to save them during a massacre oh-so-many years ago. As of now, only his current vessel remains. With the symbols for "river" and "time", which every "guardian" of the dragon is marked with, burned onto the nape of his neck; a spirit of some sort residing in his body; and no home to return to... Ryuunosuke is cursed to a fate of aimless wondering. Until the day his, extended, time on this planet runs out. Currently, his life as a vagabond has led him to the odd, little town of Stargate.
