In a way this manga is still kinda amazing with how over-the-top it can be. In context, the big bad guy of the series is essentially the worst a-hole food snob you'd ever meet in your entire life. But also add how damn creepy he is, and his brainwashing a little girl, and that goes WAY beyond that. Heck, if there was another villain in Shonen Jump I'd say he's equal with, it'd be Doflamingo from One Piece. They both come off as the most evil, creepy people you'd ever meet.
I really liked the beginning part of this chapter. I was hoping we'd get more Dojima again, and eventually get him meeting up with Soma's dad again. Of course, Joichiro being Joichiro, it took Dojima meeting Soma first to know his friend wasn't dead in a gutter somewhere. Learning that Azami was the third seat on the council of ten behind those two was a really cool reveal, and I'd love to see the both of them now get pulled into this conflict and have to try and deal with Azami themselves in some way.
I had to reread the chapter because I missed it, but Azami must have married into the Nakiri family and took his wife's last name since his was Nakamura. Which would be the reason why it was easy for Senzaemon to disown him from the family for his brainwashing of Erina.
Now we have the big overarching challange for the series: saving Erina from a crazy food critic that will brainwash her into being an even possibly greater a-hole food critic. ...good luck to ya Soma! I would find it hilarious though, if the easy way to break her brainwashing in the future is if Soma just fed her one of his horrible food experiments. One squid tentacle covered in panut butter later and Erina's back to her usual self, because her food critic self can't comprehend the horrible thing she just ate.
