The new opening was pretty good. I still think I like the first one better. The "frame shudders" in this opening I thought were the best part.
I love that they opened with Oga and Satou's buddy talking about Satou (favorite character) and then Ike. Glad to hear they're committed to tagging along with Margery when the time to leave the city comes. Minor characters got a good amount of screentime in this ep, so I really liked it. It's also good that we got more info on Balle Masque, except I'm still wondering where Silver is and who that Green Flame was that Sydney recognized.
Kashim is a very familair character, but I can't make the connection. Still too hungover...
The concept of "tuning" really intrigues me, and I can't help but wonder how it might be done. Kashim said there was alot of distortion in the city from all the Torches (and, I assume, all the repairs done to cover up the constant battles). So I would imagine, to get the place back 'in tune', you would either need to raise the level of real souls or decrease the Torches. Kashim's recruiting Yukari as a Helper made me think that it was going to be the first way. But I don't know what kind of awesome power would be needed to create actual existence... and I doubt Kashim has that much ability.
So, the only viable option for tuning would be decreasing the Torch energy. That makes Yuji the number one priority, because his Reigi Magou keeps recharging every night, outputting infinite Torch energy into the environment. Yuji has been used to create tons of torches, do huge repairs to the city, and bring people back to life, so HE is the biggest source of distortion. So, as for what happens next, I see Kashim going at odds with Shana. Since Yuji is a great help in killing Tomogara (as support to Shana), Alastor, whose main priority is killing Tomogara will want him around. Kashim seems to be more about 'the big picture' and his Flame Haze probably doesn't care about killing Tomogara if it means creating tons of distortion. Yes, I realize that is all speculation on my part (without watching the preview btw), but I also think it sounds plausible.
