I know Kurama is not a familiar but it would have been more awesome a Kurama dakimura than a Mizuki one.
About the episode, I really liked it. Out of the 3 shojos this is my favorite one and the one I have less problems in terms of adaptation. But to be honest I've forgotten many things about the manga
Hope this sells well enough to have a 2nd season with God summit arc (and if possible, Kurama arc).
Hanae's video is weird but I like those retro vibes.
