I hadn't decided how Tani appoints its chunin. Likely it's by recommendation and evaluation. But perhaps a chunin could recommend a subordinate genin for examination. The genin goes on a B-rank mission accompanied by a jounin 'proctor' that will record their progress. The mission, whether a success or failure, is later graded more or less by the jounin presenting his case to the Daimyo and possibly other strong ninja in the village.<br/><br/>That reminds me, Jun receives a complimentary Battle Vest (Archaic) with one enhancement seal, 6th level or less.<br/><br/>Edit: I knew there was a lightning wolf in Japanese myth. Hah. (http://en.wikipedia.org/wiki/Raij%C5%AB) :P
