I just picked up Spica today! Saki is a long, long ways away though. Need to pick up another 284 or so Demon Crystals. Doable since I already managed 200 of the things, but definitely will be a grind.
I also sent a ticket in about the event, random non-helpful generic response (only deviation I've seen from others was a single sentence saying that the SC we got was "not for delaying the event, but for maintenance".
