This season is probably the best season this anime has to offer, is not focus on the fighting and action but on the characters, some of them that we barely saw before but now are the protagonists . The story makes u attach to the characters and understand them , is really nice how this saga manage to avoid the easiest cliche' that we often see in animes, and can picture characters unique and interesting. Finally a bit of deep in ao no exorcist! Sound and visual are good as well. What lacks is a bit of impact on the main story for the wholeepisodes , and would be nice to see more the other casts of characters that are completly forgotten.
