I'm very interested to see where it goes. I don't really have many things to say about it because I still don't really know what to expect for the rest of the show. From what I gathered, the show seems like it could be a sort of retelling of Love Live Sunshine, but from the perspective of Yohane and her imagination. Though I could be missing something and be completely wrong about that.
So far the music is amazing as usual. I really like the artstyle as well.
Also I thought the fact that the dog is named Lailaps was a cute detail.
Now that you mentioned it, I can definitely see this show going in a direction of "retelling, but fantasy". Took me a while to remember that we've already had a Lailaps in Sunshine though, at first I thought the show is just referencing Greek mythology for no reason in particular :P
