second season fell short of first season i think but it good animation level is same as first one as for content wise story changes per two episodes, some episodes have continuous of story, new demons and angels are more focused centered around this time,two demon introuced this time despair and other one i think incubes have abilty of modify dreams as such he wishes angel motto remain same they care only about grimoire from which human can summon demon by getting it they can promotion .not affected or caring about fights, violence and theft so on happening in front of them, for them humansare living such lives because of them
comedic undertone remain same, this time stories and plotline are more focused on Azazel ,how idotic and stupid he can be
as for last four episode are focused on him how he overblow simple problems into issues that cant be solved easily, last two episode focused on his girlfriend planning to make work and to become demon king this two hilarious
yet it has not same appeal as first one, as season 1 focused more on people problems coming in detective agency, duration remain same as for previous season, you will not feel bored of it
