Quan

Quan is (as seen in Quan's dwelling) Vivi 's grampa. This is very strange because Vivi is a defect of a Black Mage and Quan was (as Vivi said : Dead) and is a Qu. Somehow Quina thought s/he recognized Quan. The link between Vivi, Quan and Quina is not completly clear and is kind of funny if you think of it.
