The "Atelier" series kicked off with the series featuring protagonists whose names ended with "ie". For the 11th title, we had this idea that the protagonist's name should end in "na," but unable to come up with a suitable name in time, two blank squares followed by "na" was inserted as a placeholder in the proposal. It was then that someone mistook this provisional name, as Rorona, having misread the blank squares as the japanese letter "ro." And so the name Rorona was born... or so they'll have you believe.
