RE: Blue Exorcist: The Blue Night Saga

Just like you say, it may not have had as much action as other things that were coming out, but the amount of story and revelations they packed was incredible. I loved Rin's whole journey into the past, finally getting to know her mother, understanding more about Satan and the whole secret of the Blue Night... it was incredible! We needed a season like this, one that focused on the lore and setting everything up for what's to come.
