Jesus. Literally, since this is an anime about diabolical characters. The first season was great, even if it was filtered with melodramatic themes, as it wasnt the main plot device, and still had other elements that were well explained. The second season came, and the pacing was very quick, the characters seemed entirely new, almost as if it's an entirely new show. Do not watch this if you were expecting the same show, it's entirely different, and has shitty pacing.
They introduce characters and do not explain at all about any of the plot, to the point where it's just a clusterfuck and insanely confusing. I was watching this with my friend, and we both watched the entire season in a day and hated it. We even watched the 1st season to compare the contrast in the characters in the newer season. Almost 10 whole years for a completely drama driven show, and I am 100% positive the only reason this would have good reviews is due to hype and fanboys who did not want to believe that this show turned into the most disrespectful attempt of the first season.
