Well, that was a pretty dramatic episode. This arc seemed a lot more self-directed. Riki didn’t have that much influence. He seemed more like an innocent observer caught in the mix. It seems like Yuiko knows the secret of the world like Kyousuke. I wonder exactly how long she has known…she’s quite the closed book.
So now that the next day has come, I guess the secret of the world will be revealed. The main clues so far are the school trip, the disappearing dwarves, and Yuiko’s goodbye. Sounds like a tragedy to me…with some time travel thrown in the mix. Still have quite some time in this series…must be pretty major.
