^But the SS isn't used on Ravel and Raiser. Besides, that would not only ruin the two-part event, it would ruin the hype for Belial's betrayal and everything else. The Nov. SS takes place between 18 and 19, iirc.

And, if that timeline is correct, does that mean Xenovia's election comes before Valerie waking up and the end of the volume?
