Ghost in the Shell: Kodansha Edition, Vol. 01 (Mature)

In a futuristic world where the line between artificial intelligence and human consciousness is ghostly thin, a cybernetic investigator is called upon to solve a peculiar case of network crime and terrorism, involving a highly intelligent being that is not organic in origin. An influential story that dares to ask what makes a human being 'human' and what, exactly, is the soul?
