I reread the entire arc and I still think it's just a complete and utter mess. More and more super vague IT'S MAGIC AND WISHES concepts are thrown on top of each other to make this shit work in a mega convient for Riko's party way. At first, we learned about balancing system. Great, it was explained pretty straightforward and aside from garbage Mitty 2.0 subplot I didn't have any problems with it. But even Mitty 2.0 could've been an interesting plot device to develop character futher if author had any balls to resolve properly. Than, flashback happened and we've got fucking Deus Ex Machina eggs, just another loli torture instrument. Since then it's absolute trainwreck. Forget about balancing, this shit doesn't work now. Forget about paying for Nanachi's freedom, a character that never was stated to be amnesiac before recovered his memories and did 180. Oh well, now Faputa is about to be tamed like a bitch with magic memories.
So, what about main characters? Reg jobbed, Riko fainted after she was crying and hiding behind Reg's back in previous chapters, Nanachi is just immortal cash cow. They did absolute jack shit, but their plot armor is impressive.
