Hey ~ yeah, I am. ^^ I get that a lot.. I just spend my time on history rather than on video games and girls.. I suppose ^^

Anyways ~ I don't think that we can say the Riaka had an "inventor" like a car. Think of the horse and buggy - can we say that a certaiin person invented it? Both the Rickshaw and Riaka, were, based on their uses, probably created from the peasant in China.. or maybe Korea/Japan.. they might have been urbanized by a certain preson.. but I doubt that that person invented it.
