I cant help but think that Noragami and its seconf season are at its core more polished versions of Blue Exorcist. Noragami deals with gods, while Ao No Exorcist is about demons. While Ao No Exorcist is pretty much what youd expect in a shounen like series, Noragami is something more. I cant promise the other way around that if you like Noragami you'll like Blue Exorcist, but I am saying it might definetly be worth a try.
Both anime contains good mixture between action and humour! The main characters are not from this world plus they manage to get humans tangled in their mess. Both anime have male protagonist who delivers in the action and humour but gets shafted by the female characters. Definitely similar level of enjoyment.
The MC's are both careless teenage boys who are unaffected by what is going on around them. Though they also show great empathic ability especially regarding their friends. They are generally laid back and funny.
This may be sound ridiculous..considering how far different the theme concept of both anime.
So? Why you recommend each other?
The story and the feeling brought.
Both of them have a similar kind of fate and bit by bits of storyline.
They are connected with Gods, powerful being that hold control to the world and how the heaven and hell hold a powerful control that determines the whole story, simply to say...JUDGEMENTS from something beyond humans.
Both of the series sacrificing the most dearest character of the main character which in the leaves a scar to us (the audience) of how the story could end with a happier kind of ending yet it is not.
Altho in that regard Shingeki no Bahamut have a more tense and tick plot while Noragami Aragoto a little bit more casual and slower.
Both have a concealed and surprising which will led us to switching opinion with some protagonist turns into antagonist and the other antagonist turns out to be protagonist.
Both have a majestic way of showing how enormous and Godly a battle between Gods, Demons and Human and...as well as showing a STRONG emotions of sadness losing someone dear to you. That pain in your chest is real.
Well, enough to say....if you like those 'pain in the chest' feeling of losing someone dear, both share the exact thing you looking for with an extra of GRAND BATTLE between HEaven and Hell.
At moments they make you happy, at others they make you cry, at others they make you rage. Monogatari Second Season and Noragami Aragoto, aside of being the two supernatural and sequels, can really be compared because of they're atmosphere. The two know perfectly when and how to manipulate the feelings of the spectator and they do it very well. If you watch them, you're not gonna forget 'em so easily
-Both about kill spirit
-Both main girl got a special power (Hiyori and Inoue)
-Both Main male character has a bad history past about them and they parents
-Both has LITTLE romance
-Both have GREAT sound affect
-Both have great plot and hooks
Sorry If you don't agree with any of these recommendations.
Both deals with the supernatural, both male MC were struggling to make ends meet, and it also involves a girl who somehow got involved with them, however one was more about comedy, while the other is about action.
Im actually SURPRISED noone made this recommendation yet.
Its so similar to the extend where it involves r/s n FEELS between gods n human n livelong phenomenon creatures (yokai / ayakashi)
Comedy wise, both are equally entertaining no lame cold jokes >.>
Artwise, man 10/10 if u like Yato theres no way u wont like Tomoe n vice versa!
Story wise, not only does both Yato n Tomoe have dark pasts but they also involved past X present n tons of amazing time leap stuff!
These 2 are definitely my very best n favourite animes of all time and whole life :')
