Both titles show characters that rely more on strategy, intelligence and cunning rather than brute force, shear determination or "The Power of Friendship" to succeed.
If you enjoy an intelligent manga then these two are for you. These titles are very smart and are very detailed and most important of all no overpowered teenager who can destroy entire mountains or planets with a single super powerful finishing move
