arrgh dont be so harsh...Ah! You don't know the rules, you don't know your rank and you don't know your opponent. And I'm the one who's spaming?
Special Jounins can only use up to C rank
Ambu Itachi was -Uchiha Itachi-
And -Uchiha Itachi- was ranked gennin, and so does ambu itachi, since they're the same person
Maybe he's able to use what he said, since he is studying at the Med school and Nexus said there were other rules for Med Nins that we don't know about, but you Can't use Costums of any kind and can't use B ranks.
-_- well this battle was all for naught,
so technically i already won.
