It's sad to admit, but this franchise is deader than the girls. Mappa doesn't seem to care about it, and the management and promotion have been awful. We've missed the timing. Just look at any other idol anime and see how much more effort they put into promoting it.
Unironically a great title for the anime. Saga, as in the prefecture, and Saga, as in 'a long story of heroic achievement'. They cooked up an incredible title for an incredible anime.
