Was eh. Maybe like a 7. Hirose always has a strong start of a story, kind flounders through the middle part, and then just abruptly decides on an ending. Anna gets together with Mei but Anna had shiptease with literally all the characters, and the other characters all had shiptease with each other as well. You could say there was hints of the final two pairings but you could also say that about anybody ending up with any body as well.
Much like Mimi Mix, where the character tries to get her ears under control and then just kinda does out of nowhere at the end with zero buildup, the whole "Anna working with the kamis to become one" just gets completely dropped without a mention and the author note going "well she was based on me so doing it would be arrogant" which seems like a cheap cop-out since that was Anna's driving narrative throughout the series.. So the overall plot gets completely dropped without even an in story mention, and we get two of the gods revealing they had made the game to merge their heavens which they do....and literally nothing changes. There's a like 4 page "We're disbanding the company!" that gets instantly and then the two pairings happen. Roll credits.
It's still good fluffy yuri, but until Hirose can figure out how to storyboard a coherent plot and follow through on it they should really just stick to slice of life stuff without any overarching plots. Which sucks a lot, cause there are usually some really interesting ideas but they never get followed through on in a satisfying way.
