What is the timeline of these stories? Like what's first and what's last in this series?
I think "Angel's downfall" to be the first one in the timeline. The other ones follow as they are published, but that's the first, I don't know why it comes in third, actually.
Anyway, it was about time that we had a flustered sensei, she almost never showed any feeling (well, we know she did, but Saaya doesn't :-D ).
I saw an image of a blindfolded sensei on Twitter. Someone knows something about it?
