“There is one key to protecting the throne. And that is not to misjudge the ambition of the young.”
This is a political strategic mind-battle manga dappled with intrigue, violence and provoking messages to the reader. It doesn’t mean this series is something overwhelming and stilted, though. The scope is indeed epic: from one’s dignity and pride to ideological inconsistencies and the world peace, - however downright realistic.
Pros:
Just the right size and pace. No dragging on the plot development. Once the tempo is set in the beginning, it proceeds till the very end. Smooth storyline makes it really easy to read and comprehend.
Art is simply amazing.
The depth of manga. On political level Sanctuary covers two worlds at once – the yakuza underworld and politics environment. It depicts their similarities and differences to the fullest. Politics/politicians go around behind the curtains, and at the same time, yakuza people respect pride, dignity and truth. And though these are the lower and the upper worlds, they co-exist and entwine with each other. On the social level Sanctuary covers contemporary problems of youth nonchalance, lack of ambitions, and stagnation of older generations. Describing all you can get a glimpse of in this manga can go on for a couple of pages.
Scope. Once again I have to emphasize that Sanctuary has a wide range of aspects implemented and balanced properly in it: a dream, friendship, love; violence, lust, fear; dignity, loyalty, trust; ideological conflicts, corruption, manipulation, change of generations, etc. In the end all those serve as a background for the two men struggling to reach their goal.

Cons:
They cry and pretty often it’s out of place and mood. Though maybe it has connection to the next disadvantage listed.
Some may find art lacking in facial expression dpt.. Although, the portrait art is mind-blowing, it is somewhat static. Maybe, the artist decided to use crying so that, at least, characters’ suffering emotions could be distinguished.
Weak representation of female characters in the manga. The female characters in this manga are simply useless and one can keep wondering, the whole purpose of introducing them in the first place. They contribute neither to the plot development, nor do their personas possess any distinctive features.
