Whoa chapter 196 was intense, and his nickname finally makes sense, it's amazing to to see how this flashback compares to Minato's flashback. Both fathers were talked about being geniuses, yet iafter Minato's flashback many fans mocked him, failing to see the supposed genius he was, as was largely a three trick pony, Rasengan, that he adapted from Bijuu, the Seals he learnt from Jiraiya and Kushina and his Flying Thunder God technique he copied off the second Hokage, he looked below par when compared to the other Hokages. Yet here we see Jouchirou and he looks like a real genius at a whole another level, no one else seems to come close to him, to a point that his hard work and dedication is overlooked by everyone else because he is so much better than everyone.
I just realised, this chapter likely means Azami was trying to turn Erina into a female version of Asura Jouchirou, It does make you wonder about Azami's motives is he trying to have a conformed standard so no other chef becomes disillusioned like Jouchirou, or is he continuing the work he felt Jouchirou left behind? Or did Jouchirou give him such a thrashing that he hardened up and became a by product of Jouchirou's rage...either way it is looking more and more like Azami is a product of Jouchirou's actions. This likely means after this arc is over, Azami will be a new man who will be forgiven for his deeds and looking very much like he'll be the Orichimaru of the series.
Interesting questions actually.
