Quite an episode indeed. It left a few confusing details, though, like if Yuri was indeed going to rape Ringo or if it was an utterly too elaborate plot to achieve something. I very much doubt she could have predicted Shouma was in the next room - unless the diary half said so - so it's a stretch in my opinion she would have done all that to get those two together. However, if her objective is to bring Momoka back, there's no point in raping Ringo. Very strange.

But anyway, like Ryll said, Yuri is much more understandable now.

I hope things will now work between Shouma and Ringo. That alone would make me happy.
