A very enjoyable episode despite most of it was original.
Spoiler for 16:
I give points to the anime team for making that pink background to Hakaze which resembles Samon's one
The anime really likes Tetsuma, in the manga he's a background character who has spoken like 3 lines so far but it's good that the anime gives him more presence although I'm not liking him.
It's funny when you compare Hanemura with and without his costume. With it he even looks badass
That girl from the Kusaribe clan was cute. I liked how Yoshino understood her and wanted to help her because of that even if Tetsuma is so convinced that he did it because he's the Mage of Exodus (it gives me the impression that he hates Yoshino or something).
Finally Hakaze accepts the fact that she loves Yoshino
The best part of the episode was definitely the preview. Finally they're animating Marine Snow! Which includes my favorite flashbacks with Aika and Yoshino
