This is just bad, can't defend this much. Bad animation, facepalming fights, music kinda unfitting, deus ex machina, wtf scenes (Yui air trombone).
Leon and Kawanami ended up being useless for the most part, and apparently shooting the gun isn't as devastating as claimed since everyone just shrugs it off (lolz she'll be fine, she just needs a new dream!). Guess having your soul shattered and your dreams lost forever isn't.....forever?
Sensei "poofs". No reason given except "he quit". No further plot regarding Engi, John, or Hercules. No answers given about Merry, the keys, or how Yumeji suddenly turned superhero. The good point of this episode is the trollfaces of Ijima and Jyukai and the nice ending song.
Having read the manga this week, this is all original material with Ijima and Jyukai. This is what should have been if they stick to the manga.

In the manga, Merry and Yumeji fight two dream demons. The previously shown little dream demon who laughs a lot and a woman who controls chains. The only part taken from the anime which in the manga was thoroughly explained was when Yumeji draws John Does saw sword. But nothing beats more awesome than Yumeji hijacking the dream connecting it to John Does world unleashing John Does army of cat girls. Moe moe. In the anime they completely failed to show Merry’s identity or powers as a gate keeper with her keys that can send them back.
Unlimited Nekogirls works! This is also a good place to stop and may be a second season. Sigh JC staff.
