Went with kind of low expectations into this one because the first chapter of the manga was meh and just felt and looked so ... different compared to E7(No surfing or bitching music as of yet).
But it proved itself to be so many times better than the manga and with Gintama gone for now and Bakuman ending, E7AO fills my weekly dose of shounen nicely.
Definitely going to keep watching.
Even if it should derp out in the middle.
I also re-watched the last episode of Nisemonogatari and I think I just "got" it somehow.
(People who didn't like Nise, read this)
Kaiki sold charms in that city (Hint by Oshino, maybe) to not make money, but to draw out something supernatural, looking for "Allies of Justice"(Kagenui was talking about Phoenix using immortality to fight evil).
After he found his true objective, he left and told Kagenui about the Phoenix
Then, Oshino(who left) and Kaiki probably worked together somehow to get Kagenui to accept her sister(Kaiki was always saying that the fake thing is far more worth than the real thing) through Koyomi.
And the ghost/sister is working for her to get accepted by her as a real sister, maybe
That's what I think, at least
