Aah yeah... now that I think about it, in chapter 1 Kasane was depressed because a lot of things had gone wrong for her recently -- and one of these things was that her fav idol retired.
I'd never had guessed that this girl would actually have a character role in the story. Omoshiroi, omoshiroi!
On another note, I don't get Meguru's calculations. Why was 14.10 the perfect time? What was she expecting to happen with Toki?
