Zankyou no Terror

Both animes focus on the mind-battle between a great detective and a smart criminal, who happens to be the main character. Death Note is a must-watch anime which sort of feels like a game of chess or a cat-and-mouse between the detective (L) and the main character (Light). Both L and Light are of exceptional intelligence and their plans are always exciting to watch. Zankyou no Terror's character's plans, in my opinion, aren't quite as clever and infallible as those of L and Light, but they're satisfying nevertheless. Rather than a cat-and-mouse game, Zankyou no Terror follows a pattern where the 'terrorists', Nine and Twelve, broadcast a riddle for the detective to solve if he wants to prevent their next terrorist attack. If you like clever schemes and interesting 'bad guy' protagonists, then you will like both of these shows.

Both start out very strong with an interesting premise and loveable characters and awesome fight scenes. Both also have disappointing anime-filler-endings but much more awesome-completely-different manga endings. Soul Eater's manga is finished though, while Ao no Exorcist's isn't at the time of writing.

Both focus on some of the more political aspects of being trapped in a world to do with games.
