Speaking of Kazuradrop...BB has used time manipulation in the past... I wonder if Smart purplehead with the best supercomputer in the world cut a deal with Smart purplehead with the best supercomputer in the Moon and that's why she had to stay behind.
Also starting to wonder if leaving Fou alone with a maybe vampire was a smart idea...Or if Nasu is planing to have Novum Chaldea wrecked while were gone
And if the time dilation didnt conveniently start recently, the implied minimum dilation of 50 to 1( 1 year per week )would make the LB year be off...
