Setsuna

At 99% and missing two gallery images. I've done every trophy that could possibly unlock art but I don't have the 100 Challenge Mode complete one or one that isn't even listed on the online lists. I'm only at like 28% overall on challenge mode. I got two arts when I hit 20% overall on challenge mode. So I don't know if I get two more at a higher % or at 100 trophy.
