Thanks for the response!
I should point out is that I didn't put the rank in order from Artistry -> Faith, but from highest to lowest rank.
Since we're on the topic of endings, I gotten 6(.1) of the endings including where you 5 hearts/stars for all 4 heroines, but I've hit a wall on how to get the 7th (I assumed that Sakuya was connected to it).
Could I get a hint on what I have to do to reach it?
