Also, were you planning on asking why Koishi did what she did to herself? I think it might actually get an interesting reaction, if Yukari does know.
That may be a good idea, actually. And it may also be worth mentioning that the satori were driven underground because of their mind-reading ability; it would show Shuuei that people aren't just okay with that kind of exposure. I'm not too sure on that one, though. Asking about Koishi I agree with, but talking about the satori in general I'm not too sure on, so discuss amongst yourselves.
Also, I won't be able to be on as much today and tomorrow (weekends in general, really), so don't think you need to wait for my input. Just remember the stuff I want to say to Shuuei about her reaction to the Koishi idea.
