I mean the creator did advise viewers to have at least read some of the manga so we'd know what the fuck is going on. Personally I haven't read it either, but will once i finish this season.
So.....We did see Ayato several times, but he's just overseeing the whole case.....So he must have something in mind and/or know more then most of the current characters on-screen know?! When is he going to the open. Kaji-kun!!! x'D
