Hello everyone,
Here we are again to talk about the on air manga/anime series Yumekui Merry after the last episode that got finally some kind of progress in the main story (even thought a little clichè to be honest).
Yes, we finally found who was the real enemy (the teacher) and really it wasn't this great surprise. He was looking plain creepy in all the shots they gave him from a long time and the last episodes reeked of "I'm evil, watch me, muahahahah" or something very similiar. (Hell, even Kyubey looks like an innocent puppy if put together with this madman)
Another important note in this episode is that my prediction that Isana was going to be involved in all this mess caused by the dream demons proved true, I seriously hope she's not going to lose her dreams and become lifeless cause it's one of my favourites characters of the show for her cheerful personality. (just after Merry that is too cute to be second)
There has to be a way to send back to the dream world these guys without hurting the host, this is not Mahou Shoujo Madoka Magica, but it supposed to be a light hearted show. 
I think the key is behind our dear Heracles that is likely to be hiding something, because he was the first to open the door and has to know more about all these happenings. (as he is the one making them happen in the first place)
This series is also lacking in another place, that is the powerless protagonist, that is able only to shout and bark like a dog, but is not able to do anything useful to the battles they find themselves in.
From what I've heard about the manga (I have to pick it up in some shipment to read it later on), Yumeji by this time should have much more powers than he is showed in the anime adaptation and this makes me shivers thinking of an rushed anime ending.
Merry is the other character of note in this series that is still shrouded into mistery for her past.
I feel there is more than meets the eye for this girl, I can only imagine that she is not a dream demon and not even a human, but some sort of watchdog between the two races as her power are too powerful to be a common dream demon, but at the same time she possess full body without having to possess anyone.
But well, those are all speculations, there are still some episodes till the end of the adaptation and I'm curious to see how they'll manage to close all the gaps in this short time,
See you soon,
