Wow...thats lot of research in there.It sounds so real and convincing,with all those added info O_O And you got it accurate too,about the roles of the Sumeragi and the Sakurazuka ^^
But the part with Setsuka reciting the story to the doll,it just felt...haunted...a bit creepy too,thou it actually look cute on her...
One piece I enjoy ^^ nice treat

i think this is brilliant -the fact that you have made some serious research before making this story. I would love to see the next chapters. i think this is going to be the most serious,well-prepared fanfiction i have ever read.
o yeah, and not many wrote about setsuka^^
