ogata judan i submit that ogata's name above his character section should have dan replaced with the japanese judan for the reason that judan is not a literal rank it is the name of a title of which he is the current holder for the duration of the series his rank is dan there is no such thing as a dan see especially the sentence challenging for the title warrants a promotion to dan actually winning the title promotes to dan and finally winning the title twice gives an immediate dan promotion if it were a literal dan rank then winning it wouldn't guarantee a promotion to dan would it
