Well-written but nihilistic, with intense grit and gore. A good read if you like Darker and Edgier stories, but occasionally rather disturbing.
This story is definitely meant to appeal to hardcore fans of Zero and Nitro+, what with the dark, violent tones. However, those aren't the only selling points, since the storytelling itself is also a superb example. In addition, no prior knowledge of Phantom is required to enjoy this one, but it does help to understand Ichiro's Assassin's backstory.
Strong characterization, but depressingly bleak and oppressive, keeping in line with the tone of the source materials. Later chapters are incredibly, incredibly brutal, verging on mean-spirited. Worth a read just for the clash with the Shadow.
